Where is the telephone code 02073 from?

Answer 1

In the UK, telephone area code 020 is London.

A number beginning 020 7536 is most likely a BT landline in Poplar; however, with number portability, any specific 020 number could be located anywhere in the greater London 020 area, served by any local carrier.

Answer 2

In the UK, area code 020 is London. From outside the UK, that's +44 20.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, and many other countries use different prefixes.)

Answer 3

In the UK, area code 020 (not 0207 or 02073, just 020) is London.

Many other countries have similar telephone area codes.
