What country code is 00153088?

Answer 1

00 = commonly used international access prefix, not part of the country code

+1 = country code for North America (USA, Canada, etc.)

530 = area code for northeastern California, USA, incl. Redding, Chico, Lake Tahoe

88 = first 2 digits of 7-digit subscriber number

Alternatively,

001 = less common international access prefix

+53 = country code for Cuba

088 = invalid number in Cuba

or,

0015 = international access prefix for faxes from Australia

+30 = country code for Greece

88 = invalid number in Greece

Because of the ambiguity in different access prefixes used in different parts of the world, it is best to quote international telephone numbers in international format, without the access prefix, with the country code prefixed only by a plus sign.
