Where Telegram OTP fits your verification flow

A user signs up and you need to know the number is real. Call the Verify API, a code lands on their Telegram, and they're confirmed in seconds, fastest in the regions where Telegram is the first app people open.
Add a second step for users who prefer Telegram to SMS. A code lands in an app they already trust, so the extra security doesn't cost you friction at login.
Send the reset code over Telegram instead of email, where it's harder for an attacker to intercept, and a read receipt tells you the user actually saw it.
Before money moves or account details change, confirm the right person is behind the action. A quick Telegram code confirms the right user is in control.
An unfamiliar device or a sensitive change should trigger an extra check. Send a Telegram code the moment it matters, with a fallback ready if the user isn't on Telegram.

Frequently asked questions

What is Telegram OTP verification?

Telegram OTP verification sends a one-time passcode to a user through the Telegram app to confirm their identity. The user enters the code in your app to prove they control the account. It's a fast, low-cost alternative to SMS, and it works well in regions where Telegram is widely used such as India, Russia, Indonesia, Brazil, Egypt, and the U.S.

Is Telegram OTP secure?

Telegram encrypts messages in transit, so verification codes are protected between Dexatel and the user’s device.

Codes are single-use and time-limited, which makes them a safe option for sensitive flows like logins, password resets, and transaction approvals.

What sender do Telegram OTP codes come from?

Codes are delivered from a shared verified sender called “Verification Codes.” Branded or custom senders aren’t supported for Telegram OTP at this time.

How much does OTP for Telegram cost?

Telegram OTP is a flat $0.024 per verification sent, the same rate in every country. There are no monthly fees and no per-conversation charges, so you pay only for the codes you send.

What happens if a user isn't on Telegram?

You can set a fallback channel such as SMS or WhatsApp through the Verify API. If the user can't be reached on Telegram, your configured fallback delivers the code instead, billed at that channel's standard rate. You control the order and timing.

Is Telegram OTP cheaper than SMS OTP?

It can be. Telegram OTP is a flat rate with no carrier fees, while SMS OTP pricing varies by country and network. In markets where Telegram is widely used, it often works out cheaper, which is why many businesses use Telegram as the primary channel and SMS as fallback.
