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 local or national landline.
Although 0333 numbers are not freephone numbers, they can often be called for no extra charge. If your tariff or call package offers inclusive calls to landlines, numbers starting with 03 will be included in the exact same way.
The 03 numbering range was introduced during 2007, as a caller-friendly alternative to more expensive business rate numbers such as 0845 and 0870.
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.
