Current codes
Subdivision names are listed as in the ISO 3166-2 standard published by the ISO 3166 Maintenance Agency (ISO 3166/MA).
BS 6879 gives alternative name forms in Welsh (cy) for some of the Welsh unitary authorities (together with alternative code elements). Since this part of ISO 3166 does not allow for duplicate coding of identical subdivisions, such alternative names in Welsh and code elements are shown for information purposes only in square brackets after the English name of the subdivision.[1]
