Calling the United States from Vietnam: A Simple Guide

Making calls internationally can sometimes seem daunting, but calling the United States from Vietnam is surprisingly straightforward. The key lies in understanding the correct dialing procedure, which involves using either a zero-zero (00) or a plus sign (+).

To make a call from Vietnam to the United States, you have two options, both achieving the same result.

Method 1: Using 00

Dial 00 1 followed by the US area code and the desired phone number.

For example, to call someone in New York City with a phone number 555-1212, you would dial:

00 1 212 555-1212

Method 2: Using +

Use a plus sign (+) followed by the 1, the US area code, and the phone number.

This method is essentially the same as the first but uses a plus sign instead of the 00.

For the same call to New York City:

+1 212 555-1212

Important Considerations:

• Remove any leading zeros: When dialing from Vietnam, ensure you don't include any extra leading zeros before the 1 or other digits.
• Area Codes: Always include the US area code before the phone number.
• International Calling Rates: Be mindful of international call rates. Check with your telecom provider for current pricing information.
• Mobile Devices: The procedures are identical for calls made from both landlines and mobile phones in Vietnam.

This simple guide should eliminate any confusion about calling the United States from Vietnam, allowing you to connect with your loved ones or business contacts with ease.
