Vietnam Virtual Number
A +84 number gives you a Vietnamese line for a fast-industrialising economy that runs on Zalo. Minutes after paying in crypto it is active, texting and calling run unrestricted both ways, and no ID is ever collected.
One price for the number. Everything else is unlimited.
You pay to hold the number, and that is it. Sending and receiving texts, taking calls, and dialling out are all included with no per-message or per-minute charge. Top up in crypto, and your number stays live as long as your plan is active.
- Unlimited SMS, send and receive, verification codes included
- Unlimited calls, inbound and outbound, no per-minute meter
- Keep the same number, month to month or by the year
A Vietnamese line for a rising market
Vietnam is one of the world's fastest-industrialising economies, a manufacturing magnet and an increasingly digital consumer market. It also runs on Zalo, the home-grown messenger that dominates chat and business locally, alongside Shopee and Lazada. A +84 line lets you register on those, reach Vietnamese customers, or stay connected, without a Vietnamese SIM or the biometric registration one now involves.
No limit applies to either direction of texting or calling: a Ho Chi Minh City 28 landline or a mobile can be the number that catches your Vietnamese codes, the one a Shopee seller rings, and the one contacts save, answered wherever you are.
There is no biometric registration behind it either: crypto settles the cost, the +84 number appears in your dashboard, and nothing about it is connected to your name.
Codes land the second they are sent
Point any signup at your Vietnam number and the verification SMS arrives in your dashboard right away, ready to copy. No SIM to swap, no roaming, no waiting. Replies and calls go back out from the same number, all included.
- Instant delivery of SMS codes to your account
- Reply and place calls from the same Vietnam line
How Vietnam numbers work
Your plan is one Vietnam +84 number with unlimited texts and calls, both ways. We assign it from the ranges available to us, so the format is not something you pick at checkout. Here is what each kind of Vietnam number looks like.
Mobile numbers
A +84 mobile line on the 3, 5, 7, 8, or 9 ranges, what Vietnamese apps and services text a code to.
City numbers
A city line, so 24 reads as Hanoi and 28 as Ho Chi Minh City, for a fixed local presence.
Toll-free numbers (coming soon)
A 1800 line, free for callers within Vietnam.
Which apps accept it
A Vietnam +84 number works for most sign-ups. A few strict apps, including some messengers and banks, reject virtual numbers by policy, so here is what to expect by type of app.
No provider can promise every app accepts every number, and app policies change. For accounts you will log into again, keep your Vietnam number rather than using a one-time code, so later login codes still reach you.
What people use a +84 number for
Register on Zalo and local apps
Vietnam runs on Zalo, and many local services want a Vietnamese number at signup. A +84 line lets you register where a foreign number is refused.
Support a manufacturing presence
For companies sourcing or producing in Vietnam, a local +84 number is a credible contact for suppliers and staff without a local SIM.
Sell on Shopee and Lazada
Vietnam's big marketplaces expect a Vietnamese number to verify. Shopee and Lazada codes arrive on the Vietnamese line, no local SIM required.
Keep Vietnam reachable
Vietnamese banks and the contacts already saved in your phone keep reaching the same +84 number no matter where your next posting is.
Good to know about Vietnam numbers
Vietnam runs on Zalo
Zalo, not WhatsApp, is Vietnam's dominant messenger, used for chat, business, and services, and a Vietnamese number helps when registering it.
How the numbers read
Vietnamese mobiles run on the 3, 5, 7, 8, and 9 ranges, while 24 marks a Hanoi landline and 28 a Ho Chi Minh City one.
Registration, avoided
Vietnam has tightened SIM registration, including biometric steps. A virtual number skips all of it, set up online and paid in crypto.
Skips the biometric step
Since the number runs on our network rather than a Vietnamese SIM, a Hanoi line rings through from Oslo or Boston with nothing more than an internet connection.
Vietnam, Zalo, and the factory-floor economy
Vietnam sits at the centre of the global manufacturing shift, drawing brands and suppliers moving production into the country, while at home its consumers have gone firmly digital. The distinctive thing is the software: where most of the world defaults to WhatsApp, Vietnam runs on Zalo, its own messenger, for everything from friends to shopfronts to official notifications.
A virtual +84 line fits both sides. It gives a sourcing manager or exporter a credible local contact number, and it gives anyone a Vietnamese line to register on Zalo, Shopee, and local services, without a biometric-registered SIM. Where a Vietnamese bank account is separately needed, the number handles the SMS side rather than the account.

Vietnam number FAQ
Any cap on how much I can text or call?+
No. SMS and voice both ways sit inside the plan, so nothing extra is charged per message or per minute.
Can I use it to register on Zalo?+
Yes. A +84 number can receive the SMS code Zalo and other Vietnamese services send at signup, which is where a foreign number is often refused.
Can I still use WhatsApp on a Vietnamese line?+
Yes. It registers and verifies on WhatsApp, Telegram, and Signal, though Zalo is the dominant app in Vietnam.
Do I need a registered Vietnamese SIM?+
No. Vietnam has tightened SIM registration, but this is set up online with no ID and crypto payment.
Will it receive Vietnamese codes?+
Yes. It takes the SMS one-time codes Vietnamese banks, marketplaces, and services send to confirm a login or a signup.
Can I keep it long-term?+
Yes. For as long as the monthly or yearly plan runs, the +84 number stays yours, working as a lasting line rather than a one-time number.
Do I have to be in Vietnam?+
No. It runs over the internet, so it answers the same from Hanoi, Boston, or anywhere else.
