How to Call UK from USA

Use this sequence when dialing from a phone keypad, calling card, or VoIP dialer that expects international access codes. It works for normal landline and mobile formats as long as the final local number is valid.

  1. Dial 011, the international exit code for USA.
  2. Dial 44, the country code for UK.
  3. Enter UK area code without leading 0 + local number. Remove any domestic trunk prefix when required, such as a leading 0 on many European numbers.
  4. Check the full number before calling. Example: 011 44 20 7946 0018.

Number format notes

International numbers work best when saved in E.164 style, meaning +44 followed by the national significant number. From a mobile phone, that usually lets you tap the saved contact from any country without changing the prefix. From a landline or office phone in USA, the manual version is 011 before 44.

If the UK number was written for local use, check whether it includes a domestic trunk prefix. Many countries write landlines with a leading 0 for local calls, but that 0 is normally removed after the country code. North American numbers are different: keep the 3-digit area code and 7-digit subscriber number after country code 1.

Costs can differ between landlines and mobiles because carriers route those calls differently. If a number has moved between providers or uses a special service prefix, the billed rate can differ from a normal city landline. For predictable spend, check the country rate before long calls and confirm whether the number is landline, mobile, or premium.
