Telecommunications

See also: List of Wales dialling codes

029 is the current telephone dialling code for Cardiff, as well as for the neighbouring towns of Penarth, Dinas Powys and Caerphilly. The dialling code is optional when dialling within the area, with it being possible to dial between any two phones within the 029 code using only the eight-digit local number.

Prior to the Big Number Change on 22 April 2000 the area had shorter, six-digit local numbers with an area code of 01222 (with 0222 preceding this, prior to May 1995). There remains a common misconception that local numbers are still six digits long and that the code is 02920, despite the existence of newer Cardiff numbers in the ranges (029) 21xx xxxx and (029) 22xx xxxx.
