UK Registration Check

Used Car Lookup by Reg

Enter a registration to see MOT history, mileage and tax status before you buy. Free, instant.

Enter a UK number plate, for example AB12 CDE

A used car lookup by registration pulls a vehicle's official details from DVLA and DVSA records: make, model, colour, fuel type, engine size, year of manufacture, MOT status and history, tax status and recorded mileage. It is free, takes seconds and is the best first step before viewing any second-hand car, though it does not show finance, stolen status or service history.

The lookup answers a large family of everyday questions, from engine size and colour to when the next MOT is due, but it is not a full vehicle history report. This explains which questions it settles, which it cannot, and where to go for the rest.

What Is A Used Car Lookup?

A used car lookup is a search by number plate that returns the facts held on official records for that vehicle. The DVLA holds registration and tax data; the DVSA holds MOT results. The free number plate check brings those together.

Who uses a used car lookup?

Buyers, sellers, owners and traders all use it, for different reasons.

  • Buyers: checking that an advert matches the car.
  • Owners: confirming their own MOT and tax dates.
  • Sellers: proving the specification to a buyer.
  • Fleet managers: keeping dates under control.

What it is not

It is not an owner finder. Names and addresses are protected data and never appear.

How To Check A Car By Reg

To check car by reg, type the registration, with or without the space, into the lookup and read the result. The details should match the vehicle's V5C and the car itself.

The routine

  1. Take the registration from the advert or the car.
  2. Enter it into the lookup.
  3. Compare make, model, colour and engine size with the vehicle.
  4. Read the MOT and tax sections.
  5. Note anything that does not match.

Typing the registration correctly

A single wrong character returns a different car or nothing at all. Letters such as O and 0 or I and 1 are easy to confuse, so read the plate carefully and compare the result with the vehicle.

Car Check By Reg: What You Will See

A car check by reg shows the official vehicle details and test history. The headline items are below.

  • Make and model: as recorded.
  • Colour: the colour on the register.
  • Fuel type and engine size: as registered.
  • First registration year: and year of manufacture.
  • MOT status and expiry: with a full test history.
  • Tax status: and the due date.
  • CO2 and Euro status: where recorded.
  • V5C issue date and export marker.

Dates are as important as details

Dates for the last V5C issue, MOT expiry and tax due tell you how recently the car changed hands or was tested, which helps you judge how current the information is.

Check Car Details By Reg: What The Answers Mean

When you check car details by reg, read each field as a clue. A mismatch between the colour on the record and the car in front of you may simply mean a respray that was never reported, or it may mean a different car. Always ask.

Fields worth a second look

  • Engine size: does it match the badge on the boot?
  • Fuel: a diesel listed as petrol is a red flag.
  • Colour: changes should have been notified to the DVLA.

Check Car Model By Reg

To check car model by reg, read the make and model on the result and compare them with the badges and the V5C. Trim levels and variants are not always shown, so look at the V5C and manufacturer details for those. The car spec check topic covers specification by reg.

Check my car model by reg

Owners who check my car model by reg are often looking for parts compatibility. Use the model and year together, because parts differ between production years.

Check Vehicle Model By Reg And Variants

If you check vehicle model by reg and need a trim level or engine variant, combine the lookup with the VIN. The VIN decodes to more detail on a manufacturer's system. The get a VIN from a reg topic explains the link.

Why do variants of the same model matter?

Two cars of the same model can have different engines, gearboxes and trims, which changes value and parts. Use the VIN and the handbook to pin down the exact version.

MOT Check By Reg

An mot check by reg returns the current MOT status, the expiry date and the full history of past tests. This is the same data the DVSA publishes on GOV.UK.

  • Status: valid, expired or not yet due.
  • Expiry date: drives your renewal plan.
  • History: pass, fail, advisories and defects.
  • Mileage: at each test.

See MOT check for detail on how to read the result.

Reading advisories

Advisories are not fails, but they show wear that is likely to need attention soon. A long list on a car you are about to buy can help you negotiate.

Check MOT By Reg Versus MOT History By Reg

If you check mot by reg you see the current certificate; mot history by reg shows all earlier tests, defects and mileage. Both come from the same record, and the MOT history topic explains the layout.

Why does MOT history matter?

Repeated advisories, long gaps and failures that return later are patterns you only see in the full history.

When the MOT is not yet due

Cars under three years old show no MOT history. That is normal and is not a red flag, so look at servicing and the V5C instead.

Check Car Tax By Reg

When you check car tax by reg, the lookup shows whether the car is currently taxed, taxed with a due date, SORN or untaxed. Tax is not transferable between keepers, so a buyer must tax the car before driving it. Read more at is my car taxed.

Check tax by reg quickly

To check tax by reg before a viewing, note the due date. A car showing as untaxed may be SORN or may have changed hands recently.

Tax and SORN

If the lookup shows SORN, the car is declared off the road and must be taxed before use. See the vehicle tax status topic for what each status means.

Can You Check Tax Cost By Reg?

If you want to check tax cost by reg, the lookup shows tax status, not the price. The amount depends on the vehicle, its CO2 or registration date and the rates set at the time, so check the current figure on GOV.UK. The vehicle excise duty topic explains the factors.

Check car tax cost by reg

When you check car tax cost by reg, use the first registration date and CO2 recorded on the lookup to find the right band on GOV.UK. Do not rely on an old figure from an advert.

Other wording for the same question

Phrases such as car tax price check by reg, check tax price by reg, tax cost check by reg and check car tax rate by reg along with car tax check by reg, check car tax price by reg and car tax cost check by reg, all mean the same: find the vehicle's details, then read the current rate on GOV.UK.

Why the figure changes

Rates differ by when the car was first registered, its emissions and fuel, and they can change between years, so a fresh check on GOV.UK is always safer than a remembered number.

Check Engine Size By Reg

To check engine size by reg, read the engine capacity on the result in cubic centimetres. It matters because tax, insurance and some parts depend on it. For power, the BHP check topic explains how horsepower relates to the registration.

  • Engine capacity: shown on the lookup.
  • Power output: not usually shown in the free lookup.
  • Fuel economy: see MPG for vehicles.

Engine size and insurance

Engine capacity affects insurance and, for older cars, tax. If an advert quotes a different engine size from the record, ask for an explanation.

Check Car Specs By Reg

Buyers who check car specs by reg will find the basics: fuel, engine size, colour and emissions data. Detailed equipment lists such as trim, options and infotainment are not on the register, so you need the manufacturer, the VIN or the advert.

What spec data is missing

  • Trim level and options.
  • Gearbox type.
  • Weight and towing capacity.

Using the manufacturer for detail

A franchised dealer can often decode a VIN into a full specification sheet, which covers options the registration record never lists.

Check Towing Capacity By Reg

If you want to check towing capacity by reg, note that the free lookup does not show it. Towing limits are set by the manufacturer and appear on the vehicle plate, in the handbook and sometimes on the V5C. Never guess, because exceeding limits is unsafe and can be illegal.

Where limits are written

Look for the plate under the bonnet or in the door frame, which lists maximum weights. Combine it with the handbook to confirm what the car may tow.

Check Car Colour By Reg And Paint Codes

To check car colour by reg, read the colour field. The lookup does not show the manufacturer's paint code, which is on a plate or sticker on the car. The car colour code finder topic shows where to look.

If the colour has changed

A respray should be notified to the DVLA so that the record matches. A mismatch on the record may mean the update was never made.

Finding the paint code

Paint codes are usually on a sticker in the door shut, boot or under the bonnet. A parts supplier can use the code to match the colour.

Check Tyre Size By Reg And Tyre Pressure By Reg

A request to check tyre size by reg or tyre pressure check by reg cannot be answered by the free lookup, because tyre data is not held on DVLA or DVSA records. Look at the sidewall, the door pillar sticker or the handbook. A tyre check by reg is really a check of the car itself.

Where tyre information lives

  • Sidewall markings.
  • Door-jamb or fuel flap label.
  • Owner's handbook.

Check Insurance Group By Reg

To check insurance group by reg, note that the group is assigned by industry bodies and insurers, not the DVLA. The free lookup does not show it, and neither does it show whether the car is currently insured. For that, askMID uses the Motor Insurance Database. See is my car insured.

Checking whether a car is insured

Insurance status is held on the Motor Insurance Database. Anyone can check that a vehicle is insured by using askMID with the registration.

Engine Check By Reg, Engine Code And DPF

An engine check by reg cannot reveal the engine code, and a check engine code by reg or check my engine code by reg request is not answered by the free lookup either. The code is on the engine or in the handbook, and a dealer can find it from the VIN. A dpf check by reg is likewise not available; DPF presence depends on the exact model and year.

Why the handbook helps

Manufacturer documents list fitted engines, DPF presence and servicing needs far better than a registration search.

Oil And Coolant Check By Reg

An oil check by reg or coolant check cannot show levels or grades from a registration; those are physical checks. The registration helps you identify the right oil specification in a manufacturer database. For the physical task see how to check the oil in a car.

Coolant

A halfords coolant check by reg style request is really a parts-finder tool offered by retailers. Use it to match the correct product, then follow the handbook.

Matching the right fluid

Use the registration and engine size with a parts catalogue to find the correct specification, then confirm it against the handbook before topping up.

Recall Check By Reg

A vauxhall recall check by reg or peugeot recall check by reg is done through the official recall service on GOV.UK or the manufacturer's tools, which search by registration or VIN. Recalls are safety notices issued by manufacturers and the DVSA publishes information about them.

  • Check on GOV.UK: for official recall details.
  • Check with the dealer: for work done.
  • Be careful: with unofficial sites.

What to do if a recall applies

Contact a franchised dealer for the make, who carries out the recall work. There is normally no charge for a safety recall, but confirm with the dealer.

ULEZ Check By Reg

A ulez check by reg uses the Euro status and fuel type to judge compliance, but the definitive answer is on the official Transport for London or GOV.UK checker. Charges and zones are set by Transport for London and local authorities, so verify before driving into a zone.

What the lookup contributes

The CO2 and Euro data on the lookup supports the check, as explained in CO2 emissions checker.

Why does a check beat guessing?

Compliance depends on fuel and emissions standard, not simply on age. An official check removes the guesswork and protects you from charges.

Vehicle Check By Reg: Quick Answers To Common Questions

A vehicle check by reg or check vehicle by reg search usually wants one fact, and the free lookup settles some of them and not others.

What it settles

  • Check my car by reg or check car info by reg: make, colour, fuel, year and engine size, which also covers a check engine by reg, check car engine by reg or car engine check by reg for capacity and fuel type (not the engine code).
  • Check model of car by reg, check model by reg, check make and model of car by reg, car model check by reg or check vehicle type by reg or check car type by reg: the make and model, with a van or car type where recorded.
  • Check vehicle specs by reg, check my car specs by reg check van specs by reg or check van details by reg: only the basics the DVLA holds, so use the manufacturer for features, parts and check alloy size by reg or check wheel size by reg questions.
  • Tax check by reg and check car tax band by reg: the status and due date, with the band worked out from the recorded CO2 or registration date on GOV.UK.
  • Check car mileage by reg or mileage check by reg: the odometer readings recorded at each MOT.

What it does not settle

  • Check who owns a car by reg: owner details are protected and never shown.
  • Check car value by reg: no valuation appears; a motor trade guide or dealer gives that.
  • Check my tyre size by reg, tyre size check by reg, check my tyre pressure by reg and check my oil by reg: the sidewall, door-pillar sticker and handbook answer these.
  • Check car insurance group by reg and insurance group check by reg: groups come from insurers, not official vehicle records.
  • Check car tax amount by reg, car tax check cost by reg, check cost of car tax by reg and check price of car tax by reg: the lookup gives status, and GOV.UK gives the current amount.
  • Check car parts by reg, check car features by reg and check specs by reg: parts suppliers and the manufacturer hold this detail, not the DVLA.
  • Check oil by reg, check engine oil by reg, check oil capacity by reg, check tyre pressure by reg and check paint code by reg: these live in the handbook, under the bonnet or on the car itself.
  • BMW warranty check by reg and similar warranty queries: only the manufacturer or dealer can confirm warranty, and a DVLA recall check by reg is done through the official recall service on GOV.UK.

If you only have a registration, typing it into the free check car by reg number tool is a sensible first step; just treat anything it cannot show as a question for the seller or manufacturer.

Why a vehicle history check goes further

A vehicle history check from a commercial provider (HPI is the best-known name, and several others offer similar reports) draws on finance, insurer and police sources, including data that can reach the Police National Computer. It can help confirm vehicle provenance, such as whether a scrapped vehicle has been recorded as destroyed, and it does not replace seeing the logbook (the V5C) in person.

What A Used Car Lookup Does Not Show

The free lookup deliberately stops at official data. It does not show:

  • Outstanding finance: held by finance companies.
  • Stolen vehicle status: police data via commercial checks.
  • Write-off category: from insurers through MIAFTR.
  • Service history: garages and manufacturers.
  • Number of previous keepers: protected data.
  • Insurance status: askMID.
  • Owner details and VIN.

The what does a number plate check show topic sets out the boundaries.

Used Car Lookup Versus A Full History Check

Free lookup compared with a commercial check
FeatureFree lookupCommercial history check
MOT history and mileageYesYes
Tax statusYesYes
Outstanding financeNoYes
Stolen markerNoYes
Write-off categoryNoYes
Service historyNoNot usually

Choosing between them

Use the free lookup for every car and a commercial check on any you are serious about. The free versus paid vehicle checks topic goes into the trade-offs, and a car finance checker style check covers finance.

Where each tool stops

The free lookup stops at official data; a commercial check adds finance, stolen and write-off markers; neither shows service history in full.

Checking A Used Car Before You Buy

A lookup is one step in a wider routine. Follow this order.

  1. Run the registration through the free lookup.
  2. Read the MOT history and mileage.
  3. Run a commercial history check.
  4. Inspect the car and read the V5C.
  5. Test drive and negotiate.

The what to look for when buying a used car topic adds practical tips, and used car history checks summarises the records.

Reading Mileage In The Lookup

The lookup includes the odometer reading at each MOT, which lets you see whether the mileage rises sensibly. A reading that falls is a warning. The mileage check topic explains how to read the pattern.

Motorbikes, Vans And Classics

The same lookup works for most road vehicles registered in Great Britain, but with caveats.

  • Motorbikes: usually included; frame numbers matter.
  • Vans: high mileage is normal.
  • Classics: historic vehicles may be MOT exempt, so history may be thin.
  • Electric vehicles: zero tailpipe emissions but still need MOTs when due.

Northern Ireland And Imports

Great Britain records come from the DVLA and DVSA; Northern Ireland tests are run by the Driver and Vehicle Agency (DVA), so results can differ. An imported vehicle may have no history before its UK registration, so ask for foreign documents.

Common Mistakes With A Lookup

  • Treating a clean MOT as proof of condition.
  • Believing no finance appears so there is none.
  • Entering a wrong character: check carefully.
  • Ignoring a colour mismatch.
  • Relying on a seller's screenshot instead of running your own.

Why running it yourself matters

Screenshots can be edited. Run the registration yourself.

A clean record is not a guarantee

A lookup shows what was recorded. It cannot show what was never reported, so always inspect the car.

When The Record Looks Wrong

If the details do not match the car, do not assume the lookup is wrong. Ask the seller to explain. If your own record has an error, correct it through the DVLA or the test station via GOV.UK.

Where The Official Sources Are

The official services are the DVLA Vehicle Enquiry Service and the DVSA MOT history, both on GOV.UK. The DVLA Vehicle Enquiry Service topic explains what it returns. For the final word, always check GOV.UK.

Frequently Asked Questions

How do I check a car by reg for free?

Enter the registration into a free lookup built on DVLA and DVSA records. It shows make, model, colour, fuel, engine size, MOT status and history, tax status and recorded mileage. It does not show finance, stolen status, service history or owner details, so use it as the first step and add a commercial check for a serious purchase.

What information does a car check by reg show?

The free result usually shows the make, model, colour, fuel type, engine size, year of first registration, MOT status with expiry and full test history, tax status, CO2 and Euro status where recorded, the V5C issue date and whether the vehicle is marked for export. It does not show insurance, finance or owner information.

Can I check tax cost by reg?

The lookup shows whether a vehicle is taxed, not the price. The rate depends on the vehicle, its emissions or registration date and the current rates, so use the details from the lookup and check the figure on GOV.UK. Do not rely on an old advert, because rates can change.

Can I check tyre size or tyre pressure by reg?

Not with the free lookup, because DVLA and DVSA records do not hold tyre data. Look at the sidewall markings, the sticker on the door pillar or fuel flap, or the handbook. Retailer tools that match tyres to a registration use separate databases and should be checked against the car itself.

Can I check insurance group by reg?

No. Insurance groups are set by industry bodies and insurers and are not shown on DVLA or DVSA records. The free lookup also does not show whether a car is insured. For that, askMID searches the Motor Insurance Database, and a quote provider can show the group for a specific model.

Can I check towing capacity by reg?

The free lookup does not show towing capacity. The manufacturer sets limits, which appear on the vehicle plate, in the handbook and sometimes on the V5C. Never guess, because exceeding limits is unsafe and can be illegal. A franchised dealer can confirm the figure for the exact model.

Can I do a recall check by reg?

Yes, through the official recall information published on GOV.UK or via the manufacturer, which can search by registration or VIN. Recalls are safety notices, and a dealer carries out the work. Use official sources rather than unfamiliar sites, and check again if you buy a car second hand.

Can I do a ULEZ check by reg?

The Transport for London checker uses the registration to say whether a vehicle meets the standard, and the lookup's fuel and Euro status data support it. Zones and charges are set by Transport for London and local authorities and can change, so always confirm with the official checker before driving in.

How do I find the engine code of my car by reg?

The free lookup does not show it. The code is usually on the engine itself, in the handbook or on a manufacturer database searched by VIN. A franchised dealer can help. If you need it for parts, supply both the VIN and the registration so the supplier matches the right variant.

Does a used car lookup show if there is finance?

No. Outstanding finance is held by finance companies and appears on commercial history checks. A clean lookup does not mean a car is free of finance. Run a finance check before paying, and ask the seller whether the car has ever been on a finance agreement.

Can I find a car for sale by reg?

No. A registration lookup verifies a specific car; it does not list cars for sale. Find the car through an advert or a dealer, then run the registration through the lookup and a history check before travelling to view.

Does the lookup work for motorbikes and vans?

It generally works for road vehicles registered in Great Britain, including motorbikes and vans, showing MOT, tax and basic details. Frame numbers matter on bikes, and exempt historic vehicles may show little history. Northern Ireland tests are run by the DVA and may not appear in the Great Britain record.
