Key Facts

Overview

0845 numbers are non-geographic telephone numbers within the United Kingdom's telephone numbering system. Unlike traditional area-code numbers (such as 020 for London or 0121 for Birmingham), 0845 numbers are not tied to a specific geographic location, allowing businesses and organizations to maintain a single contact number regardless of where they are physically based.
