Calling from Vietnam to the United States

To call United States from Vietnam, follow this exact dialing sequence:

00 + 1 + Area Code + 7-digit phone number
  • 00 - Vietnam's international access code
  • 1 - United States country code
  • Area Code - Specific U.S. area code
  • 7-digit number - The local phone number

Example: To call (312) 555-0123 from Vietnam, dial: 00 1 312 555 0123

Useful tip: Prevent misdials and unnecessary expenses by checking who owns a number with the United States phone verification service. If you know you should be calling to a specific U.S. city, let's say Albuquerque, then you should use phone number lookup tool for Albuquerque, New Mexico, or its area codes (505, 575).
