Standard rate numbers
What are 0333 numbers?
0333 numbers and all other numbers starting with 03 are standard landline rate numbers used by businesses, government and other organisations.
Using 03 numbers instead of area-specific local landline numbers gives companies more flexibility in handling incoming calls but does not cost the caller any extra.
0333 number call costs
0333 numbers, and all other numbers that start with '03', cost the same to call as a normal landline.
The cost to call 0333 numbers is the same as calling a normal local or national landline.
If your tariff or call package offers free or inclusive calls to landlines, numbers starting with 03 will be included in the exact same way.
All phone numbers beginning with 03 work in the same way. Although they differ from traditional landlines by not being linked to any specific location, they cost the same to call - this is a legal requirement put in place by the UK telephone regulator, Ofcom.
The 03 numbering range, including 0333 numbers, was introduced during 2007.
Information about 0333 numbers applies to all UK numbers starting with 0333, including those that begin 03330, 03331, 03332, 03333, 03334, 03335, 03336, 03337, 03338 and 03339.
