What are the most frequently asked questions about calling Vietnam from the US?
What is the US exit code to call Vietnam?
The US exit code to call Vietnam is 011. You'll need to dial this code first, followed by Vietnam's country code (84), then the area code (if applicable), and finally the local phone number.
To make an international call from the US to Vietnam, you must dial a specific sequence of numbers. The "exit code," sometimes referred to as the "international access code," is necessary to tell the US phone network that you are about to dial an international number. Without it, the system will interpret the digits as a domestic call. Think of it like dialing "1" before a long distance call within the US; "011" serves a similar purpose for international calls. Therefore, the complete dialing format from the US to a landline or mobile phone in Vietnam is: 011 + 84 + Area Code (if applicable) + Local Phone Number. For example, to call a Hanoi number (area code 24) that is 3928-1111, you would dial 011-84-24-3928-1111. If you are calling a mobile number, replace the area code with the mobile prefix (e.g., 90, 91, 92, etc.).What is the Vietnam country code?
The country code for Vietnam is +84. You'll need to dial this code before the Vietnamese phone number when calling from the United States.
When making a call to Vietnam from the US, the full sequence you'll dial is: 011 (US exit code) + 84 (Vietnam country code) + area code (if applicable, without the leading zero) + local number. The "011" is the exit code for the United States, which tells the US phone system that you're making an international call. Remember to omit the leading zero from the area code in Vietnam. For example, if you are calling a number in Hanoi (area code 024), the sequence will be: 011 + 84 + 24 + the 8-digit local number. Always verify the specific area code for the location you are calling in Vietnam to ensure you dial correctly. Mistakes in the area code or local number will prevent the call from going through.How do I dial a Vietnamese mobile number from the US?
To call a Vietnamese mobile number from the US, you need to dial the exit code 011 (for the US), then the country code for Vietnam 84, followed by the Vietnamese mobile number without the leading zero. So the full format is: 011 + 84 + Vietnamese mobile number (without the leading zero).
To elaborate, when dialing internationally, it's essential to first dial the exit code for the country you are calling *from*. In the US, this exit code is always 011. Next comes the country code for Vietnam, which is 84. Finally, you dial the Vietnamese mobile number. Vietnamese mobile numbers typically start with a zero, but you must remove this leading zero when calling from outside Vietnam. For instance, if the Vietnamese mobile number is 0901234567, you would dial 01184901234567. Keep in mind that international call charges can vary significantly depending on your phone plan. Before making the call, it's advisable to check with your mobile carrier or VoIP provider to understand the rates. Many apps and services like WhatsApp, Skype, or Viber allow you to make calls to Vietnam using an internet connection, which can often be a more cost-effective option.What are the cheapest ways to call Vietnam from the US?
The cheapest ways to call Vietnam from the US generally involve leveraging Voice over Internet Protocol (VoIP) services or utilizing international calling apps that take advantage of internet connectivity instead of traditional phone lines. These methods significantly reduce costs compared to direct dialing through your mobile carrier.
Several VoIP services and apps specialize in international calls. Popular options include Google Voice, Skype, WhatsApp, Viber, and Rebtel. These services typically offer per-minute rates that are significantly lower than traditional long-distance charges. Some, like WhatsApp and Viber, allow free calls to other users of the same app, making them ideal if your contact in Vietnam also uses the service. Keep an eye out for promotions or special calling plans, which can further reduce costs. Remember that data charges might apply if you are not using a Wi-Fi connection.
Another cost-effective strategy is to look into international calling cards, both physical and virtual. These cards often offer competitive rates, although you should pay attention to hidden fees and expiration dates. Alternatively, consider purchasing an international calling plan from your existing mobile provider. While these plans are usually more expensive than VoIP services, they can be convenient if you prefer to manage all your communication through a single provider. Before committing, carefully compare the rates, fees, and terms of service for each option to find the most economical solution for your needs.
Do I need to remove the leading zero when calling a Vietnamese number?
Yes, when calling a Vietnamese phone number from the United States, you must remove the leading zero that appears at the beginning of the Vietnamese number.
Vietnamese phone numbers typically begin with a zero when dialed within Vietnam. However, this leading zero is a trunk prefix used for domestic calls within the country. When dialing internationally, this prefix is not needed and should be omitted. Including it will likely result in your call not being connected or reaching the wrong number.
Therefore, the proper format for dialing a Vietnamese number from the US is: 011 (US exit code) + 84 (Vietnam country code) + the Vietnamese number *without* the leading zero. For example, if the Vietnamese number is 090 xxxxxxx, you would dial 011 84 90 xxxxxxx.
Are there apps I can use to call Vietnam from the US?
Yes, numerous apps allow you to call Vietnam from the US, leveraging Voice over Internet Protocol (VoIP) technology to make international calls more affordable than traditional phone lines. These apps use your internet connection (Wi-Fi or mobile data) to transmit voice data, often offering significantly lower rates compared to standard international calling plans.
Many popular and reliable apps offer this functionality. Some, like WhatsApp, FaceTime, and Facebook Messenger, are primarily designed for communication between users of the same platform, but they can still be used to call mobile or landline numbers in Vietnam if the recipient also has the app or if you purchase credits within the app. Other apps, specifically designed for international calling, such as Skype, Viber, and Google Voice, allow you to dial any phone number in Vietnam, regardless of whether the recipient uses the same app. These apps typically require you to add funds to your account or subscribe to a calling plan to cover the cost of the international call. When choosing an app, consider factors like call quality, pricing, ease of use, and the availability of features such as video calling or messaging. Always check the app's current rates for calls to Vietnam, as these can vary depending on the app, the type of number you're calling (mobile vs. landline), and any promotional offers. It's also important to ensure you have a stable internet connection to avoid dropped calls or poor audio quality.What's the time difference between the US and Vietnam when calling?
The time difference between the US and Vietnam is significant, ranging from 11 to 14 hours, depending on the specific US time zone and whether Daylight Saving Time (DST) is in effect in the US. Vietnam operates on a single time zone, Indochina Time (ICT), which is UTC+7. Therefore, when calling Vietnam from the US, you need to factor in this considerable difference to avoid calling at inconvenient hours.
To accurately determine the time difference, you must first identify the US time zone you are calling from. The contiguous US has four main time zones: Eastern (ET), Central (CT), Mountain (MT), and Pacific (PT). During Standard Time, the differences are as follows: Eastern Time is 12 hours behind Vietnam, Central Time is 13 hours behind, Mountain Time is 14 hours behind, and Pacific Time is 15 hours behind. The impact of Daylight Saving Time (DST) in the US reduces these differences by one hour during DST's active period.
Keep in mind that not all US states observe DST. For example, Arizona (except for the Navajo Nation) does not observe DST. Furthermore, Hawaii is 17 hours behind Vietnam, and other US territories may have even greater differences. Before making your call, double-check the current time in both your location and Vietnam using a reliable online time zone converter or world clock to ensure you're calling at an appropriate time.
