Question: what is the difference between 0845 and 0345 telephone numbers?
Answer: 0345 numbers are UK wide numbers (like 01 and 02 prefixes), and are therefore cheap to call (they can often be free or included in call packages.) ... 0845 numbers are local rate numbers which cost more to call. As it costs more to call these numbers, they can often be free to set up and point to a UK landline.
