Calling the U.S.A. Long Distance
The U.S.A. is a vast country that spans 6 time zones, so it’s important to consider where you are calling and what time it will be when you do so. U.S. time zones include Eastern Time, Central Time, Mountain Time, Pacific Time, Alaska Time, and Hawaii Time. All of the United States participate in Daylight Saving Time except for Hawaii and Arizona. As of 2007, Daylight Saving Time is in effect from mid-March through early November.
The country code, or the first number you will dial, for the United States of America is 1. The U.S.A. adheres to the North American Numbering Plan (NANP), so all area codes have 3 digits.

For a call to New Orleans, dial the area code 504, followed by the 7-digit subscriber number: 1-504-xxx-xxxx. Check out our list of major area codes.
