Where is land code 0079 and area code 504?

Answer 1

Telephone country code +7 (dialed as 00 7 from many places) is Russia and Kazakhstan. A number beginning with +7 9 is a Russian mobile phone.

(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.)
