Which area code in Spain is 902?

Answer 1

A telephone number in Spain beginning with 902 (or +34 902 in international format) is a "national-rate" number. It may or may not be reachable from outside Spain.

(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.)
