Dialing the USA, Step by Step
The country sits inside the North American Numbering Plan (NANP). Below is the standard sequence to follow when you dial in from another country.
Exit Code
Begin with the international exit code for wherever you are.
00 for Europe/UK.
0011 for Australia.
(On a mobile or VoIP line, a simple + replaces it.)
US Code (+1)
Punch in +1. The same code covers the United States, Canada, and parts of the Caribbean.
Area Code & Number
Add the 3-digit area code, then the 7-digit local phone number.
Example: 212-555-0199
How US Phone Numbers Are Built
Every US number runs to 10 digits once you set the +1 country code aside:
3-digit Area Code joined to 7-digit Subscriber Number.

Frequently Asked Questions
Which country code do I use to call the USA?
The United States uses +1. Enter it right after your local exit code, which is 00 or 011, and just before the 3-digit area code.
Does calling a US mobile cost more than a landline?
Usually not. Across much of Europe and the wider world a mobile costs more, but the US runs on a 'Receiving Party Pays' system, so dialing a US mobile generally costs the same per minute as dialing a landline.
Can I reach a US toll-free number from another country?
Standard toll-free prefixes (800, 888, 877, 866, 855, 844, 833) frequently fail when dialed from outside the US on an ordinary carrier. Intercalling's VoIP service carries the call over the internet, so you can still get through.
Should I dial a 1 ahead of the area code?
Yes. From outside the US the pattern is +1 (Area Code) Number, where that leading 1 serves as the country code.
