Free 03 Numbers (SIP DIDs)

03 numbers are non-geographic numbers, not assigned to a fixed location and covering the whole UK to offer a fully national presence. Unlike other non-geographic numbers 03 are charged at the same rate as 01/02 numbers.

We can offer 03 non-geographic numbers with calls received instantly redirected to your current 01/02 number, a mobile or even SIP UR (VoIP). There are several 03 ranges:

- 03303 (These are available online for instant activation)
- 0300 (public sector/charities only)(please contact if you require an 0300 number).

Typical Application

- Your national number for your business

Cost to caller
