Get OTP codes right inside Telegram with the OTPVN Mini App

You no longer need a browser to rent a number. The OTPVN Mini App runs right inside Telegram: renting numbers, reading codes, topping up and managing your account all happen in your chat with the OTPVN bot.

What can the Mini App do?

• Sign in with Telegram, no password to remember.
• Rent numbers for OTP codes for 900+ services, just like on the website, with carrier and prefix choice.
• The bot messages you the code as soon as it arrives, with the number and the service.
• Top up and see your history inside the app.
• Once Telegram is linked to your web account, both share the same balance.

Get started in a minute

1. Open the bot @otpvn2026_bot in Telegram.
2. Tap Start.
3. Choose “Open the app” in the welcome message, or the “Rent” button next to the message box.
4. Pick a service and tap rent to get a number. The code shows up in the app and in the chat.

What else does the bot do?

Besides renting numbers, the OTPVN bot:

• Sends your login security code if you turn on two-step login on the website.
• Sends a password reset link when you forget your password.
• Delivers important announcements from OTPVN.
• Lets you chat with support right in Telegram.

The same guarantees as the website

Each rental still waits about 4–7 minutes for the code, and if none arrives the money goes back to your balance automatically. You can still rent the same number again within about 15–30 minutes, and voice OTPs still work. For a full walkthrough with Zalo, see how to rent a number for a Zalo OTP.

Frequently asked questions

I already have a web account. Do I need a new one?

No. Link Telegram to your web account (on the Account page) and you share the same balance and history in both places.

Does the Mini App cost anything?

No. You only pay for each rental, at the same price as on the website.
