An 03 number is a number that allows your customers to call you for free (depending on their call plan) from anywhere in the UK.

1. Numbers beginning with 030 (such as 0300 and 0303 numbers) which can only be used by Government / Public Sector and Registered Charities

2. All other 03 numbers (such as 0330 and 0333 numbers) that can be used by everyone else.
