Time in the US. the United States is on GMT-5 in winter and GMT-4 in summer. That is the main time zone. the United States has several, so check the city before you call.
Busy cities have several area codes on top of each other, so Manhattan also uses 646, 917 and 332.
Toll free numbers start with 800, 833, 844, 855, 866, 877 or 888, and many of them cannot be called from outside North America.
Inside the US you dial 1 before the area code for long distance calls. From abroad that same 1 is the country code.
Numbers 555 0100 to 555 0199 are kept for films and examples, so they never ring a real person.
Missed call from +1?
The FTC warns that one ring scam calls often come from area codes like 268, 284, 473, 649, 664, 767, 809, 829, 849 and 876, which look American but belong to Caribbean places that share +1, so calling back is charged at international rates.
