Home > Numbers > 03 Numbers. What you need to know


03 Numbers are UK-wide numbers. They are not associated with any particular location, but are charged at the same rate as 01 or 02 numbers.

Within the 03 ranges there are three different groups of numbers which are aimed at specific users and businesses.

033 Numbers

The 033 ranges are available for anyone to use and are available on a first-come basis via our website.

0344 and 0345 Mirror Numbers

These ranges are known as mirror numbers as they can only be obtained if the requestor has the existing "mirror" 0844 or 0845 number.

Anyone that wishes to obtain an 0344 or 0345 number must have the equivalent 0844 or 0845 number.

For example, if you have 0845 388 7744, you can apply for 0345 388 7744.

030 Numbers

Numbers starting with 030 are specifically reserved for public sector bodies, charities and other non-profit organisations.
