In my experience IDs are checked very informally by most companies such as utilities, etc. GDPR access requests usually require a proof of identity and I very much doubt they are checked beyond the details on them matching the account so it can be yet another vector for stealing more data based on the passport. Banks are probably the only place where they may be checked against s lost/stolen DB but it won't prevent you getting your SIM & phone number taken over because someone impersonated you to your mobile carrier.
