How much does it cost to call an 02 number on TalkTalk?

TalkTalk (all one word) offers both a broadband and mobile network in the UK. It was originally part of the Carphone Warehouse, but they parted company in 2010 and became disparate businesses.
02 numbers are also known as geographical numbers as they are linked to specific areas of the UK. On landlines with TalkTalk these may be up to 13p. For mobile networks with TalkTalk they may be 3p to 55p, those these prices are approximate. It may cost more if you are using your phone abroad. Many phone packages offer a number of free calls, so it is always better to check.
Please contact Ofcom if you are experiencing problems with either your landline or mobile phone call charges and they may be able to assist.
