Is area code 529 real or fake?

Answer 1

There is no telephone area code +1 529 in North America (USA, Canada, etc.).

Country code +52 is Mexico, and there are valid numbers beginning with +52 9. A telephone number beginning +52 9 is a landline in the southernmost part of Mexico.

If 529 shows up on your caller ID, it might be a call from southern Mexico, or it could be a telemarketer or other caller with a PBX (business phone system) that has been "accidentally" mis-programmed to send nonsense instead of valid Caller ID.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
