What is the MID Database UK 2026

Last reviewed: 26 April 2026

What the Motor Insurance Database is and who operates it

The Motor Insurance Database is the UK's authoritative central register of motor insurance policies. It is operated by the Motor Insurers' Bureau (MIB), a government-backed, industry-funded organisation established under a Memorandum of Understanding with the Secretary of State for Transport, on behalf of all FCA-authorised UK motor insurers.

Every FCA-authorised UK motor insurance company is legally required to report all policy lifecycle events to the MID: policy inception, policy renewal, mid-term material changes (vehicle change, address change, driver change), and policy cancellation. These events must be reported to the MID within a defined timescale, typically within seven days of the event, with inception reporting required within 24 hours on electronically transacted policies.

The MID contains details of: every insured vehicle (by registration number); the insurer providing the cover; the policy number; the policy period; the use class; and the policyholder's details. This information is accessible to: police forces for roadside enforcement; DVLA for automated enforcement via number plate recognition; other UK insurers for underwriting verification; and the insurer's own fraud prevention systems.

The legal basis for the MID lies in the Road Traffic Act 1988, supplemented by the Motor Vehicles (Compulsory Insurance) (Information Centre and Compensation Body) Regulations 2003 and retained EU Motor Insurance Directives under UK law post-Brexit. The MID is the UK component of the pan-European motor insurance information exchange system, enabling insurance verification for cross-border incidents.

How insurers report to the MID

Every FCA-authorised UK motor insurer, whether a direct brand, a Lloyd's syndicate, or a specialist underwriter, must hold MIB membership as a condition of conducting motor insurance business in the UK. MIB membership includes the obligation to report all policy data to the MID within the required timescales and to fund the MIB's uninsured driver compensation scheme through a levy on UK motor insurance premium volume.

Policy reporting occurs through a standardised electronic reporting interface between the insurer's policy administration system and the MID database. The reporting covers all policy events in near-real-time for electronically transacted policies. Manual or telephone-transacted policies may take up to 24 to 48 hours to appear on the MID following inception.

The consequence of this reporting structure: from the moment a motor insurance policy is incepted, the insurer's systems report the vehicle's registration number to the MID. The vehicle appears as insured on the MID within hours of policy inception for most direct and online transactions.

The AskMID consumer service

The MIB operates AskMID (askmid.com) as a free consumer-facing service that allows any member of the public to check whether a specific vehicle registration number appears on the MID as currently insured.

The AskMID service does not display the specific insurer, policy number, or policy terms, it confirms only whether the vehicle registration appears as insured on the MID at the date and time of the query. A positive result ("this vehicle appears to be insured") means the registration number is currently in the MID. A negative result ("this vehicle does not appear to be insured") means either the vehicle is genuinely uninsured, the policy has been incepted but not yet reported to the MID (within the 24-hour lag), or the registration number was entered incorrectly.

Policyholders who have recently incepted a policy should check AskMID within 24 hours of policy start to confirm MID registration. A negative result within 24 hours of inception may indicate a reporting lag rather than a genuine uninsured status, allow 24 hours before contacting the insurer to investigate.

DVLA's automated number plate recognition enforcement

DVLA uses the MID as the data source for its Continuous Insurance Enforcement (CIE) programme. The CIE system cross-references DVLA's registered vehicle database against the MID, identifying vehicles that appear on the DVLA register (as registered keeper, not SORN-declared) but do not appear on the MID as insured.

Where this cross-reference identifies a vehicle as apparently uninsured, DVLA issues an automatic Insurance Advisory Letter to the registered keeper at the address held on the V5C, a warning to insure the vehicle or declare it SORN. Failure to respond results in a Fixed Penalty Notice of £100. Failure to pay the Fixed Penalty Notice escalates to court proceedings.

DVLA also provides MID data to police forces for roadside enforcement via automatic number plate recognition (ANPR) cameras deployed on roads and at roadside checkpoints. A vehicle whose registration does not appear on the MID is identified immediately by ANPR and can be stopped and dealt with by officers under the Road Traffic Act 1988, section 165 (failure to provide insurance details) and section 143 (uninsured driving). Officers have the power to seize and impound uninsured vehicles at the roadside.

Key Figures

MID and cross-border incidents: the European context

The MID is the UK component of a pan-European motor insurance information exchange system established under EU Motor Insurance Directives and retained in UK law post-Brexit. Under the Compensation Body and Information Centre regulations, each EU member state maintains a national motor insurance database (the UK's MID being one), and these databases are cross-referenced for international claims.

Where a UK-registered vehicle is involved in an accident in an EU member state, the injured party or their insurer can query the UK's MID (through the Green Card Bureau / MIB international department) to identify the UK insurer responsible for the UK vehicle. This enables cross-border injury and damage claims to be pursued against the correct insurer.

UK vehicles no longer require a Green Card to enter EU member states following the 2021 post-Brexit bilateral arrangements, the MID cross-referencing system provides equivalent insurance verification. However, the MID-based verification applies to UK-registered vehicles. Drivers taking foreign-registered vehicles into the UK should confirm their vehicle's insurance registration on the relevant country's motor insurance database before travel.

DVLA confirmed the post-Brexit MID international arrangements at gov.uk. The BIBA broker finder at biba.org.uk/find-insurance/ can provide advice on cross-border motor insurance for policyholders with international driving requirements.

Frequently Asked Questions

What is the Motor Insurance Database?

The MID is the UK's central register of all valid motor insurance policies, operated by the Motor Insurers' Bureau on behalf of FCA-authorised UK motor insurers. Every UK motor insurance policy must be registered on the MID by the insurer.

How do I check if my car is on the Motor Insurance Database?

Use the free AskMID service at askmid.com. Enter your vehicle's registration number to confirm whether it appears as currently insured. Allow up to 24 hours from a new policy inception for the MID registration to appear.

What happens if my car is not on the Motor Insurance Database?

DVLA's CIE programme cross-references the DVLA vehicle register against the MID. A vehicle registered with DVLA but not appearing on MID (and not SORN-declared) receives an automatic warning letter and, if unresolved, a £100 Fixed Penalty Notice from DVLA. Police can also seize uninsured vehicles identified by ANPR cameras.

How quickly does a new insurance policy appear on the MID?

For electronically transacted policies (online or direct), MID registration typically occurs within 24 hours of inception. Most standard direct brand policies appear within a few hours. Check askmid.com 24 hours after policy inception to confirm registration.

Who operates the Motor Insurance Database?

The Motor Insurers' Bureau (MIB) operates the MID on behalf of all FCA-authorised UK motor insurers. The MIB is a government-backed, industry-funded organisation established under a Memorandum of Understanding with the Secretary of State for Transport.
