02921 isn't a phone code in the UK.
However, Cardiff has the area code of 029 and some of the local numbers there begin with '21' so a number (029) 21xx xxxx is probably in Cardiff.
A lot of people wrongly write numbers in the style 02921 xxxxxx which confuses others into thinking '02921' is an area code, when it isn't!
