Factual error: During the mid-credits scene T'Challa is addressing the United Nations about Wakanda's true nature. A Welsh flag can be seen among the other nation's flags, which would suggest that Wales is a separate nation from The United Kingdom - not the case.
Factual error: The ambulance in the museum robbery scene has the registration number LD59 QQI. In the UK Q is never used within a registration number, only as a prefix for particular vehicles, for example kit cars. The letter I is also never used in any part of a registration number as it can be confused with a 1. (00:19:07)
Suggested correction: Sounds like this is merely similar to phone numbers starting with 555 or impossible IP addresses in films.

No, this would by like having a phone number start with 5Q5 and impossible IPs are valid mistakes.
