To find out who your car is insured with, you can try the following methods:

• Search your email inbox for keywords like "car insurance," "policy," or your vehicle registration number, as insurance companies usually send policy documents electronically. Check your spam or junk folders too.
• Check any physical paperwork or documents you might have stored where you keep important files; these may include your insurance provider's name and policy details.
• Look through your bank or credit card statements for payments to an insurance company, which can help you identify your insurer.
• Use the Motor Insurance Database (MID) or askMID service online to confirm if your car is insured. While this service shows if you have valid insurance, it may not always disclose the insurer’s name directly.
• If you still cannot find the insurer, you can submit a Data Subject Access Request to the MID for your insurance details, usually requiring proof of identity.

These steps should help you identify your car insurance provider efficiently.
