Misconceptions
It is a common misconception that the code for Cardiff is 02920, whereas in fact it is 029 followed by an eight-digit local number. This is due to Cardiff previously having a 5 digit code (01222) with six-digit local numbers and that all of its local numbers begin with 20 until 2005. This problem is also widespread in cities with other 02x codes such as Coventry, London, Portsmouth and Southampton, and in the region of Northern Ireland.
