🇺🇸 🇨🇦 +1 country code
+1 is not one country but a shared numbering plan: the United States, Canada and more than twenty Caribbean and Pacific territories all use it, told apart only by the three-digit area code that follows. A +1 call from an unfamiliar area code may be international.
- Country code: +1
- Time: UTC−11 to UTC+10

A +1 number is not always domestic
Area codes such as 876 (Jamaica), 809 (Dominican Republic) and 284 (British Virgin Islands) look like US codes but connect internationally. "One-ring" scams use them to get you to call back at international — sometimes premium — rates.
How to dial +1
- Within the US and Canada: dial 1, the three-digit area code, then the seven-digit number (or the ten digits alone, where local calls allow it).
- From abroad: dial your exit code (or + on a mobile), then 1, the area code and the number.
- Caribbean +1 codes dial the same way but are billed as international — check the area code before calling back.
