What are 03 numbers?

What are 03 numbers and how much do they cost?

Ofcom introduced UK-wide 03 numbers as an alternative to chargeable 08 numbers, such as 0870.

These numbers allow organisations to have a non geographic number without callers having to pay any extra to call them.

Calls to 03 numbers cost no more than a national rate call to an 01 or 02 number and must count towards any inclusive minutes in the same way as 01 and 02 calls.

These rules apply to calls from any type of line including mobile, BT, other fixed line or payphone.
