Vietnam Phone Number Format

Country code +84 — Complete guide to Vietnam phone number formats, mobile and landline structures, and area codes.

Number Format Overview

Phone numbers in Vietnam use the international country code +84. When dialing from outside Vietnam, you must include this country code before the local number.

International Format

From the United States

011 84 [area code] [local number]
When dialing a number within Vietnam, local dialing rules apply. You may need to include a trunk prefix (often 0) before the area code for domestic calls, but you should omit this prefix when dialing internationally.

Dialing Tips

  • Remove the leading zero: When dialing internationally, drop the trunk prefix (usually 0) that is used for domestic calls in Vietnam.
  • Use the + notation: From a US mobile phone, use +84 instead of 011 84.
  • Verify the number length: Make sure you have the correct number of digits. If your call does not connect, check whether you need to add or remove an area code digit.
  • Save contacts in international format: Always store phone numbers with the full +84 prefix so they work from any country.
