Most phone numbers in United States are written in the following formats:
Prefix: long distance or international -------------------------------------- | Carrier or area code | -------------------- | | Subscriber number | | ----------------- v v v AAA SSS-SSSS - Local format +1 AAA SSS-SSSS - International format
Most telephone numbers in United States have 10 digits and are written in the format of "AAA SSS-SSSS". Here are some examples: 800 335-2247; 305 876-7000.
When dialing locally inside United States, dial the phone number directly as "AAA SSS-SSSS". Long distance prefix is not needed.
When dialing from outside of United States, the international dial-in prefix "+1" is required. So the format becomes "+1 AAA SSS-SSSS".
When dialing from United States to other countries, the international dail-out prefix "+" or "011" required.
To validate phone number formats for other countries or regions, see our Generic Phone Number Format Validator.
