The main benefit of using a 0345 number is that the cost of your call is usually the same as it would be when calling a landline 01 or 02 number, whether making the call from a landline or a mobile. Nevertheless, we'd still recommend that you check with your current provider (mobile or fixed line), who will be able to send you a list of all UK call charges.

034 and 037 numbers are non-geographic numbers that have been assigned by Ofcom to replace existing 084 and 087 numbers.

030 numbers are specially designated for use by government, councils, public services, not-for-profit organisations, and charities when used for new allocations.
