Until 2005, Russia had several area codes beginning with 0, but the 0 was changed to a 4 (e.g., +7 095 became +7 495), except that area code +7 011 changed to +7 401.
(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, and many other countries use different prefixes.)
