055 corporate numbers

Varies by provider

Corporate numbers assigned to a single business customer.

Calls to this range are billed as two parts: an access charge set by your own provider, plus a service charge set by the organisation you are calling. Adverts must quote both.

055 numbers are UK corporate numbers. Businesses use them to route calls to different offices or staff, so a call from 055 is usually from a company.

What are 055 numbers?

055 is a non-geographic range set aside for corporate numbering. A company can publish a single 055 number and have calls forwarded to different sites or people without customers noticing.

Calls are charged like calls to a standard UK geographic number, and are usually included in landline and mobile minutes.

Should you worry about an 055 call?

The range itself is not dangerous, but because it is cheap and flexible it is also used by sales teams and, occasionally, scammers. Treat an unexpected 055 call the same way as any unknown business call: do not share passwords or pay anything over the phone, and look the company up independently.
