03 Numbers - Explained
What is an 03 Number?
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. Calls to 03 numbers will cost your callers the same as calls to geographic numbers (starting 01 or 02), and be included as part of any inclusive call minutes or discount schemes in the same way as geographic calls.

03 Numbers are split into two categories:

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.
