Statistics as at February 2012[1]

With a population of over 1.8 million people, BT is the second most populous UK postcode area, after the B postcode area (Birmingham, 1.9 million).



Belfast had already been divided into numbered districts. Today, the Belfast post town covers postcode districts BT1 to BT17 and part of BT29. In common with all addresses in Northern Ireland, Belfast postcodes start with the letters BT, a mnemonic of the capital city's name. The commercial centre of the city is designated BT1 and the surrounding districts form a roughly sequential clockwise ring around the city. The postcode of the Royal Mail offices at Tomb Street in Belfast is BT1 1AA.

Rest of Northern Ireland

Certain addresses in BT29 located at Belfast International Airport (a total of 31 delivery points) are in the post town of BELFAST despite being geographically under the post town of CRUMLIN, which has the remaining 7,206 delivery points in that postcode area.[2]
