What is the dialling code from belfast to mayo?

Answer 1

County Mayo, Ireland, has several different area codes, including at least 094, 096, 097, and 098. Calling from the UK, including Northern Ireland, you must dial the number in full international format: replace the leading 0 of the Irish area code with country code +353. From a mobile, dial +353 9x; from a landline, dial 00 353 9x, followed by the local number (mostly 5 digits).

(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.)
