How to Call USA from UK
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.
- Dial 00, the international exit code for UK.
- Dial 1, the country code for USA.
- Enter 3-digit area code + 7-digit local number. Remove any domestic trunk prefix when required, such as a leading 0 on many European numbers.
- Check the full number before calling. Example: 00 1 212 555 0198.
Number format notes
International numbers work best when saved in E.164 style, meaning +1 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 UK, the manual version is 00 before 1.
If the USA 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.
