The BT postcode area, also known as the Belfast postcode area, covers Northern Ireland and was the last part of the United Kingdom to be coded, between 1970 and 1974.

Belfast

Belfast had already been divided into numbered districts. Today, the Belfast post town covers districts 1-17, 58 and part of 29. 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.
