0300 Charity Numbers & Public Sector Phone Numbers

0300 Numbers for Charities, Government & Not-for-Profit Organisations

0300 numbers are a special range of non-geographic telephone numbers reserved by Ofcom exclusively for charities, public sector organisations and recognised not-for-profit bodies.

Unlike standard business phone numbers, 0300 numbers cannot be used by commercial organisations. This makes them a trusted and recognised choice for charities, NHS services, government departments, local authorities, housing associations, educational institutions and Community Interest Companies (CICs).

If you are looking for 0300 charity numbers, 0300 telephone numbers or need advice on 0300 number eligibility, our team can help you secure and deploy the right solution for your organisation.

Can a Business Use a 0300 Number?

No. Ofcom 0300 numbers are reserved exclusively for charities, public sector bodies and qualifying not-for-profit organisations.

Commercial businesses that do not meet the eligibility criteria should instead consider alternative number ranges such as 0333 or 0330 business numbers.

A 0300 number is a UK non-geographic phone number designed specifically for organisations that provide public benefit, charitable services or public sector functions.
