Toll-free and premium numbers in the United Kingdom
Toll-free numbers in the United Kingdom start with 0800 or 0808 when dialled inside the United Kingdom (800 or 808 after +44 from abroad) and have 7, 9 or 10 digits after the country code. Premium-rate numbers start with 0842–0845, 0870–0873, 090, 091, 0982–0984 or 0989. Example: 0800 123 4567, or +448001234567 in E.164.

What each type means for the caller
- Toll-free: 0800 or 0808

- One national number for a business with several sites, routed to the nearest or chosen office. 10 digits after +44.
- Personal number: 070
- A follow-me number that forwards to whatever phone its owner chooses, so the digits don't reveal the line behind it. 10 digits after +44.
- VoIP: 056
- Numbers issued for internet telephony services rather than a fixed line or a mobile network. 10 digits after +44.
Writing and dialling a United Kingdom toll-free number
Inside the United Kingdom, dial the number with its leading 0. From abroad or in E.164, drop the 0 and put +44 in front: 0800 123 4567 becomes +448001234567. Many freephone numbers still only accept calls from inside the United Kingdom, and a call from abroad that does connect is usually charged.
Toll-free and premium numbers in a phone list
In a lead or customer list, a toll-free number usually reaches a company line rather than a person, and a premium-rate number costs you money to call. The free toll-free number checker flags them in a pasted list or CSV, and the United Kingdom phone number format page covers mobiles and landlines.

Common questions
- What is the toll-free prefix in the United Kingdom?
- United Kingdom toll-free numbers start with 0800 or 0808 at home, written +44 800 or 808 internationally. Every valid toll-free number starts that way, though not every number with those digits is in service.
- How many digits is a United Kingdom toll-free number?
- 7, 9 or 10 digits after the country code +44, plus the trunk prefix 0 when dialled inside the United Kingdom.
- Can I call a United Kingdom toll-free number from abroad?
- Sometimes. Dial +44 and the number without the leading 0. Many freephone numbers only take calls from inside the United Kingdom, and where they do connect from abroad the call is usually charged.
- How do I spot a premium-rate number in the United Kingdom?
- By its first digits: 0842–0845, 0870–0873, 090, 091, 0982–0984 or 0989. The prefix tells you the range is charged; the actual price is set per service.

- Ranges, lengths and examples: Google libphonenumber numbering-plan data (libphonenumber-js 1.13.15), the data our validator uses.
- Official plan: ITU-T E.164 national numbering plan for United Kingdom. The regulator’s filing is the authority when the two disagree.
The numbering plan only knows what a range was issued for.
In the US and Canada mobiles and landlines share the same prefixes, and anywhere a number can be ported or reassigned the range stops telling the whole story. A live carrier lookup asks the network data instead, which is what Pro + Phone ($49.99/mo) adds.
- 5,000 live carrier lookups a month: real line type, including US numbers
