The Motor Insurance Database (MID) is the UK's central record of all insured vehicles, managed by the Motor Insurers' Bureau (MIB). Police, the DVLA, and cameras at the roadside all query the MID to check whether a vehicle is insured. Your insurer is legally required to update the MID within seven days of a policy starting. You can check your own vehicle at askMID.com for free. If your car does not appear — even though you are insured — contact your insurer immediately, as it may trigger an Insurance Advisory Letter under Continuous Insurance Enforcement.

What the MID is and who runs it
The Motor Insurance Database is a national register that holds details of every valid motor insurance policy in the UK. It was established to combat the problem of uninsured driving and is maintained by the Motor Insurers' Bureau under a statutory obligation. Every insurer operating in the UK must submit policy data to the MID — it is not optional.
The database is queried millions of times a week: by police officers at the roadside, by Automatic Number Plate Recognition (ANPR) cameras, by the DVLA when cross-checking its own vehicle register, and by border agencies checking vehicles entering and leaving the UK.
How your policy gets on the MID
When you buy or renew a motor insurance policy, your insurer is required by law to submit the policy details to the MID within seven days. In practice, most major insurers upload electronically within 24 hours. The record includes your vehicle registration number, the policy start and end dates, the insurer's details, and a reference number.
Midterm changes — adding a driver, changing your vehicle, changing your address — should also be reflected within seven days of the change. This matters because roadside and camera checks reference the registration number, not the policyholder's name.
There can be a short gap between the policy start date and your details appearing on the MID — sometimes up to 7 days. Carry your insurance certificate (or a digital copy) for at least the first week on any new policy, so you can show evidence of cover if stopped before the MID updates.
Checking your own record on askMID
Anyone can check whether a vehicle is on the MID at askMID.com. A basic check is free: enter the registration number and the site returns a yes/no on whether a valid policy is recorded. It does not reveal the insurer's name or policy details to the public — that information is accessible only to police and authorised agencies.
If you are involved in an accident and need to find the other driver's insurer (for example, in a hit-and-run or where the driver cannot produce documents), you or a solicitor can request insurer details through the MIB's formal process, not through the public portal.
What happens when a vehicle is not on the MID
The DVLA continuously cross-references its vehicle register against the MID. Any registered vehicle with no matching insurance record — and no SORN declaration — is flagged under Continuous Insurance Enforcement. The sequence is:
- The MIB identifies a gap: the vehicle appears in the DVLA register but not the MID.
- An Insurance Advisory Letter (IAL) is sent to the registered keeper's address, warning them to insure the vehicle or declare SORN within a set period.
- If no action is taken, a £100 fixed penalty notice is issued.
- Continued non-compliance leads to court prosecution, with an unlimited potential fine.
- DVLA enforcement officers may clamp or seize the vehicle from public roads.
Importantly, this can happen even if you are in fact insured — if your insurer has not yet uploaded your policy. This is why checking askMID shortly after a policy starts and chasing your insurer immediately if the record is absent is important.
The MID and claims: why accuracy matters
In any accident, the MID is the first reference point for identifying insurers. If your record is out of date — for example, showing an old vehicle or a lapsed policy — it can slow down a claim significantly. Third parties may not be able to identify your insurer quickly, adding delay and potential costs.
Equally, if you are the victim of an accident caused by an uninsured driver, the MIB's Uninsured Drivers Agreement covers you — but the MID is what establishes whether the other driver had any cover at all. Keeping your own record accurate speeds the process if you ever need to make this kind of claim.
Key actions to keep your MID record accurate
- Check askMID.com within 7–10 days of any new policy or renewal.
- If your vehicle is not shown, email or call your insurer and ask them to upload to the MID urgently.
- After changing your vehicle mid-policy, verify the new registration appears within a week.
- After cancelling a policy, confirm SORN is declared if the vehicle is going off the road, so no CIE letter follows.
