Where in North America is area code 399?

Answer 1

There is no area code 399. However, it is relatively easy for a telemarketer (or anyone with a medium-sized business phone system) to send a false number for Caller ID.

Please also be very careful about any calls that come up with all zeroes as the number as this is reported to be associated with scams.

Answer 2

There is no area code 399 in North America (+1 = USA, Canada, etc.).

There is also no area code 399 in Mexico (+52).

International telephone country code +39 is Italy, but there are no valid numbers beginning with +39 9.

(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.)

Answer 3

There is no area code 394 in North America (USA, Canada, etc.).

Telephone country code +39 is Italy, but there are no valid numbers beginning with +39 4.

(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.)
