Telephone numbers starting with 0845 and 0870 are classed as 'non-geographic' numbers, which means they're not tied to a particular location. These numbers are usually used by large companies, banks and other businesses.
Calls to 0845 and 0870 numbers may be free from your BT landline depending on which calling plan you're on. This doesn't include dial-up internet calls to ISPs, or calls to dial-through or calling card access numbers.
Do I need to opt-in?
No, it's automatic. If you're on a calling plan you'll be able to make inclusive 0845 and 0870 calls at certain times covered by your calling plan.
Are 0871 and 0844 calls included?
No, calls to 0871 and 0844 numbers are not included. Additionally, calls to Internet Service Providers (ISPs) and dial-through and calling card access numbers are not included.
What is a dial-through access number?
A dial-through access number is any number which connects you to another number that is both known by and could be directly dialled by you from your BT landline. The dial-through access number charges a cheaper rate. There are typically two types of these calls.
1. You first dial an 0870 or 0845 number, and then, while still connected, you dial the intended destination number to be connected;
2. You're connected directly to the intended destination number by dialling an 0870 or 0845 number, having previously routed the destination number through an 0870 or 0845 number, which can be done via the internet or by other means.
