You can call your insurance provider (insurance company, broker, etc.) and they can tell you by accessing your record on the MID.
Alternatively, you can go to www.askmid.com and check your own vehicle registration is on the MID.
Type in your vehicle registration mark (VRM) and tick the disclaimer as appropriate and askMID will check the MID and return a ‘yes’ or ‘no’ indicator as to whether your vehicle is on the MID today.
It may also display any vehicle make and model details that may have been loaded to the MID by your insurance company. If there is no make and model detail displayed, there isn’t a problem, it simply means your insurance company chose not to load this data and there is no issue with this.
