0333 Numbers

0333 numbers are special use landline numbers that are not tied to any geographic location. This means that when you receive a call from a 0333 number, you have no way of knowing where it’s coming from. These numbers are used for government bodies, charities, public sector, and not-for-profit organizations and are in use across the UK. While the numbers aren’t tied to any geographic location, they don’t cost any more to call than standard, geographic-based landline numbers, like 01 or 02 numbers.

Since 0333 numbers don’t cost any more to call than a normal home or business landline, that means they are often included in call packages if you’re calling from a landline, or in included ‘talktime’ or bundled minutes when calling from a mobile.

0333 numbers were introduced as an alternative to chargeable 084 and 087 numbers. 0300 numbers let companies have a single point of contact for customers or interested parties without having to charge people extra to call them.

Calling costs for 0333 numbers

While a 0333 number is not categorized as a freephone number, calling them will not result in any added charges. Any 0333 number you call should be charged at your standard network rate. This applies to all 0333 numbers you call, no matter what the digits are afterwards.
