Geographic telephone numbers are a conventional method of assigning landline numbers that indicate a specific geographical location. In traditional telecommunication practices, for instance, a 0207 number is associated with Central London, while a 01273 number is linked to Brighton.

Businesses can opt for a UK Geographic number, allowing callers from UK landlines and mobiles to reach them at standard rates. 

The unique aspect of Internet Telephony is that users can select any geographical number, regardless of their actual location. This means having a number associated with a specific location around the world. 

These numbers serve various purposes, offering businesses a telephone address even if they are physically located elsewhere.
