056 numbers UK — VoIP, cost, who is calling

056 is the UK Location-Independent Electronic Communications Service (LIECS) range — Ofcom's name for VoIP numbers that are not tied to a geographic area. Calls cost the same as a 01 or 02 landline call, included in mobile inclusive minutes. The 056 range is small, niche, and mostly used by enterprise VoIP customers who want a portable national number without using the 03 family.

#What 056 actually is

Ofcom defines the 056 range as the Location-Independent Electronic Communications Service prefix — the formal name for what consumers think of as 'VoIP numbers'. Unlike 020 / 0121 / 0161 landlines (which carry an implicit geographic association even when delivered over VoIP), 056 numbers carry no geographic claim and can be allocated to any UK communications customer.

#What 056 costs to call

056 calls are charged at the same per-minute rate as a 01 or 02 landline call, and are included in inclusive minute bundles on every major UK mobile network in 2026. There is no service charge, no per-minute revenue share, and no premium uplift.

#Who uses 056 in the UK?

056 ranges are concentrated among enterprise VoIP wholesalers and their resellers. Looking at the Ofcom Numbering Data, common 056 Range Holders include:

• Voicehost — UK VoIP-first provider, large 056 portfolio.
• Voipfone — long-standing UK VoIP reseller.
• Magrathea Telecommunications — wholesale SIP, common backbone for resellers.
• Gamma Telecom — large business-telecoms wholesaler.
• Andrews & Arnold (AAISP) — engineering-focused UK ISP and VoIP carrier.

End-users on 056 tend to be: distributed UK businesses without a fixed office, freelance technical workers, regional charity networks, and edge-case telephony products (PBX testbeds, call-routing demos). 056 is rarely the first choice for a public-facing consumer service.

#Is 056 a scam prefix?

No more than any other non-geographic prefix. 056 has the same allocation eligibility as 03 (open to any UK customer through their VoIP provider) so the prefix itself isn't a trust signal either way. The same playbook applies:

1. Look up the number on this site to see the Range Holder.
2. Search the number + the company name they claim to be from.
3. If the call concerns money, accounts or credentials, hang up and ring back via a number you trust.
