0345

0345 is a four-digit prefix used in the United Kingdom as part of the national non-geographic numbering system. Numbers that begin with 0345 are typically assigned to businesses and public bodies for contact lines, such as customer service, helplines, and support desks. The 0345 prefix sits within the wider 03 numbering range, which was created to provide non-geographic numbers that are portable between providers and, in many cases, priced similarly to geographic numbers for landlines.

In terms of billing, calls to 0345 numbers are generally not tied to a specific geographic location. For landlines, many operators price 0345 calls at the same rate as calls to 01 or 02 numbers. Mobile networks, however, may charge per minute according to the user’s tariff, and some inclusive-minute bundles fully cover 0345 calls. Pricing can vary by operator and plan, so callers are advised to check their tariff.

0345 numbers are distinct from geographic area codes because they do not map to a particular place. They are designed to be portable; a business can keep the same 0345 number when switching service providers. The use of 0345 and other 03 numbers is governed by UK telecoms regulation to promote price transparency and consumer protection; providers are typically required to publish clear cost information and ensure fair access.

Overall, 0345 functions as a nationwide contact number that offers businesses a stable, non-geographic option for customer communication, balancing accessibility for callers with predictable pricing for organizations.
