Formatting an 029 number

029 numbers should be displayed in the format 029 xxxx xxxx or (029) xxxx xxxx, with the first space always placed between '029' and the eight-digit local number.

For international callers, use: +44 29 xxxx xxxx.

02920, 02921 and 02922 numbers should all be written as above; formats such as '02920  xxxxxx' are incorrect. [Why?]

Notes and links

The 029 area code has existed since April 2000, when it replaced the older 01222 area code. As of 2014, standard local numbers begin with 20, 21 or 22.

Just under 80 million local numbers can be accommodated in the 029 area code; this is ten times the capacity of the codes allocated to bigger cities such as Bristol (0117) or Birmingham (0121).

As of March 2014, only 3% of available Cardiff 029 numbers have been allocated. This reflects the fact that when first introduced the 029 area code was planned to replace all other area codes in Wales at a later date. This would have led to a single area code for all of Wales, with all landlines able to dial each other using just the eight-digit local number, as is the case in Northern Ireland.
