02920 Numbers


In the UK, an 02920 number is a normal landline phone number within the Cardiff (029) area code.

Any UK number beginning with 029 is a Cardiff number. The '029' area code at the beginning is optional if you're dialling from one Cardiff 029 landline phone to another.


029, 0292 or 02920?

There is no 02920 area code. Since the year 2000, Cardiff has had the three-digit area code 029, followed by eight-digit local numbers.

The correct way to write a number beginning '02920' is (029) 20xx xxxx, as this clearly distinguishes the optional 029 area code from the eight digit local phone number. (Why this matters...)

Have things changed?

During the year 2000, Cardiff's area code changed from 01222 to 029, while its old six-digit local phone numbers were prefixed with '20' to make them eight digits long.

For example, (01222) 872087 became (029) 2087 2087. The overall length of the number is the same, but dialling locally now needs eight digits to be dialled instead of six.

The new system gives Cardiff nearly 80 million numbers: (029) 20000000 to (029) 99899999. Prior to the change, less than 800,000 were available: (01222) 200000 to (01222) 998999.
