Avoid tying the business to one geographic area
An 0330 number does not identify one particular town or city, making it suitable for national and multi-site organisations.
0330 BUSINESS NUMBERS
0330 National Phone Numbers for Business
An 0330 number gives your organisation a UK-wide contact point without tying the business identity to one town or city. Choose an available 0330 number through UKDDI and connect it to the phone service your team already uses or wants to adopt.
QUICK ANSWER
What you need to know
0330 is a UK non-geographic 03 number range. Ofcom rules mean calls to 03 numbers cost callers no more than calls to geographic 01 and 02 numbers and must be included in the same call allowances where those geographic calls are included.
CHOOSING THE RIGHT OPTION
Why businesses choose 0330 phone numbers
0330 is useful when your customers are spread around the UK and a single national-facing number makes more sense than a local area code.
Familiar 03 call pricing for customers
Ofcom requires calls to 03 numbers to cost no more than equivalent calls to 01 and 02 numbers, including the same treatment within inclusive allowances.
Use one number across changing locations
Because call delivery can be IP-based or diverted, the organisation can retain a stable public number while the answering location changes.
HOW IT WORKS
Connect an 0330 number to your business phone system
Choose the number first, then select how incoming calls should reach your users.
0330 SIP trunk
Deliver the number to a compatible PBX or 3CX installation using SIP.
0330 hosted VoIP
Use hosted business phones when you want cloud extensions and user-based call handling.
0330 call forwarding
Divert incoming calls to an existing UK landline or mobile for a straightforward setup.

Multi-site business contact number
