What are 0345 numbers?

Telephone numbers starting with 0345 prefixes are national UK helplines used for a variety of purposes including customer service support, sales, donations and general enquiries. Their use became prominent from 2015 following a change in legislation which outlawed the use of the more-expensive 0845 numbers for use as post-sales customer care support.
