With their decline in official use, there is often confusion surrounding towns and cities which lie near county boundaries, such as Belfast and Lisburn, which are split between counties Down and Antrim (the majorities of both cities, however, are in Antrim).
Med deres tilbagegang i officiel brug, opstår der ofte forvirring i de byer, der ligger nær et amts grænse, som Belfast og Lisburn, der er delt mellem amterne Down og Antrim (størstedelen af begge byer ligger dog i Antrim).
