Where in the UAE is area code 56?

Answer 1

A UAE telephone number beginning with +971 56 (or 056 within the UAE) is an Etisalat 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.)
