National, low-cost numbers

A national number your customers can afford to call

03 numbers are not linked to any area, so they give you one number for the whole country. Calls cost the same as calling a normal 01 or 02 number, and they count towards the inclusive minutes on most landline and mobile plans.

That makes 03 numbers a fair, trusted choice for customer service lines, helplines and organisations that want one number for every office.

  • Charged like a normal landline call
  • Included in most callers' inclusive minutes
  • One number for all your sites
  • Easy to move to new premises without changing number

0300 numbers are for public-sector and not-for-profit organisations only, under Ofcom rules. Businesses can choose 0330, 0345 or 0370 instead. They cost callers exactly the same.

FAQ

03 number questions

How much does it cost to call an 03 number?
The same as a call to a normal 01 or 02 landline number. Calls to 03 numbers are included in the inclusive minutes on most landline and mobile plans.
Who can have an 0300 number?
Ofcom reserves 0300 numbers for public-sector bodies and not-for-profit organisations such as charities. Any business can choose 0330, 0345 or 0370 numbers, which cost callers the same.
Should I choose 0345 or 0370?
0345 and 0370 numbers work exactly like 0330. They are popular with organisations that already have an 0845 or 0870 number and want a matching, cheaper-to-call alternative.
Are 03 numbers free to call?
No. For numbers that are free to call, see freephone 0800 and 0808 numbers. 03 numbers cost callers a normal landline rate.
Where can my calls go?
Anywhere in the UK: a landline, a mobile, or our cloud phone system. You can change the destination at any time in myAlphaTalk, or set different destinations for office hours and evenings.
Can I bring a number I already have?
Yes. We can move most UK numbers to Alphatalk from your current provider, and our team manages the switch so your calls keep flowing. See number porting.
