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.
