What country has has the area code 002921?

Answer 1

'00' isn't part of the country code, it is a commonly used international access prefix. However, country code +292 does not exist.

Some countries use '002' as an international access prefix, which would leave country code +92, which is Pakistan.

(This is why it is confusing and incorrect to include the access prefix with the country code. The country code should be quoted with the plus sign (meaning "insert your international access prefix here") and the one-, two-, or three-digit country code. For example, the United States and Canada are +1, Pakistan is +92, and Ghana is +233.)
