{{main|Counties of Northern Ireland|Local government in Northern Ireland}}

In Northern Ireland, a major reorganisation of local government in 1973 replaced the six traditional counties and two [[county borough]]s ([[Belfast]] and [[Derry]]{{efn|name="LDerry"|The city and county officially named ''Londonderry'' are often called ''Derry''. See [[Derry/Londonderry name dispute]].}}) with 26 single-tier districts for local government purposes. In 2015, as a result of a [[Reform of local government in Northern Ireland|reform process that started in 2005]], these districts were merged to form 11 new single-tier "super districts".

The six traditional counties remain in use for some purposes, including the three-letter coding of [[British car number plates#Northern Ireland|vehicle number plates]], the [[Royal Mail]] [[Postcode Address File]] (which records counties in all addresses although they are no longer required for postcoded mail) and [[Lord Lieutenant#Northern Ireland|Lord Lieutenancies]] (for which the former county boroughs are also used). There are no longer official 'county towns'. However, the counties are still very widely acknowledged, for example as administrative divisions for sporting and cultural organisations.
