Non-geographic 0343 UK virtual numbers
0343 numbers and all other numbers starting with 03 are standard landline rate numbers used by businesses.
Using 0343 numbers instead of area-specific local landline numbers gives companies more flexibility in handling incoming calls but does not cost the caller any extra.
This is because if you have an allowance of inclusive calls to 01 and 02 numbers, that allowance will also cover calls to 0343 numbers on the exact same terms. This rule covers all landline and mobile providers and has been in place since 2007.
All 03 numbers, including 0343 and 0345 numbers, work in the same way. Although they differ from normal landlines by not being linked to any specific location, they cost the same to call.
