0300 numbers can only be ordered and used by public sector bodies and non-profit organisations such as registered charities.
Ofcom considers that the bodies eligible to use 0300 numbers should meet at least one of two basic criteria:
They should appear on one of the lists of appropriate bodies on Ofcom’s Guidance on bodies eligible to use 030 telephone numbers.
They should fulfil any of the other criteria indicated by Ofcom in the Guidance on bodies eligible to use 030 telephone numbers.
Please note that if you order a 0300 Number and you are not eligible, TTNC is obliged by regulation to re-claim the number, regardless of whether the number has been advertised online or is in print.
