Why do UK numbers start with 0?

In the UK it’s 00. 44 is the country code for the UK. 0 is the long distance dialling code within the UK, from STD (subscriber Trunk Dialling) used to access the ‘long distance’ or trunk network. You don’t need it if dialling the UK from overseas as the call arrives already on the trunk network.

Why do we add 0 before phone number?

Dialling “0” before the mobile phone number was a practice followed for outstation mobile numbers before the government allowed inter-circle mobile number portability, which effectively meant that there was no trunk dialling when it came to mobile numbers and all numbers were considered local.

Do British phone numbers begin 0?

The United Kingdom adopts an open dialling plan for area codes within its public switched telephone network. Therefore, all area codes have a preceding “0” when dialling from within the United Kingdom. When dialling a UK number from abroad, the zero must be omitted.
