How to get your Seis verification code online

Choose a country

Pick a country from the price list above. Each one shows the current price and how many numbers are in stock.
Get your number

Tap Buy SMS (top up your wallet first if it is empty). The price is held from your wallet, not charged, and a private number appears in your dashboard.
Enter it in Seis

Type the number into Seis where it asks for your phone number, then ask it to send the verification code.
Receive the code

The Seis verification code shows up in your dashboard, usually within a minute or two. If no code arrives, the hold goes back to your wallet and you can try another number.

About Seis verification

Seis can ask for a phone number to verify an account, and sends a one-time code by SMS to confirm it. That is where a private number helps: the code comes to your dashboard, not your personal phone.

Today we have Seis numbers in 13 countries, from $0.40 to $5.28. The cheapest right now are United States ($0.40), Indonesia ($0.44) and Brazil ($0.44). Start with a cheap, well-stocked country, and switch if a number is turned away.

Price range: $0.40 to $5.28
Typical delivery: Usually a minute or two, when the code comes
Number window: Up to about 20 minutes; the timer shows the exact time

Tips for a smooth Seis verification

Have Seis open on the screen that asks for your number before you buy, so the code window starts when you are ready.
Wait for the app's resend timer before asking for a new code; repeated requests can get a number turned away.
If a number is refused or no code comes, tap Cancel & refund and try another number or country. Retrying costs nothing.

Private temporary number vs free public inbox

Free public inboxes are fine for a quick test, but every code sent to them is public. A private number keeps the sign-up code to you; for an account you will log in to again, add your own number or email and turn on two-step verification right after, or rent a number.

Seis number FAQ

What does a verification number for Seis cost?

Seis numbers cost from $0.40 to $5.28 today, with a median of $0.49 across 13 countries. The cheapest right now are United States ($0.40), Indonesia ($0.44) and Brazil ($0.44). Prices update several times a day, and you only pay if the code arrives.

Which country is best for Seis verification?

The cheapest well-stocked countries for Seis right now are United States, Indonesia and Brazil; if one number is turned away, try another country.

What if my Seis OTP never arrives?

Not every number gets a code. If yours does not, you are not charged: the price is only held while you wait, and it goes back to your wallet automatically when the timer ends. You can also tap Cancel & refund after a few minutes and try another number.

How long do I have to receive the Seis code?

Up to about 20 minutes per number; the timer on your number shows exactly how long. When a code comes, it usually arrives within a minute or two, but not every number gets one, because some apps turn certain numbers away. If nothing comes, the hold is refunded and you can try another number or country.

Is this a temporary number for Seis?

Yes, and a private one: the number is yours alone for one Seis verification, for up to about 20 minutes, and the code shows only in your dashboard. Free public inboxes are different: anyone can read the messages there.

Can I receive a second code or log in again later?

The number is meant for one verification within its window, so finish signing up in one go. If you need to log in again later or receive codes over weeks, rent a number instead.

Why does Seis say the number is not valid or blocked?

Apps sometimes turn away certain number ranges, even real SIM numbers. If that happens, tap Cancel & refund and get another number or pick a different country. You are not charged for a number that never received a code.

Are these real SIM numbers?

Most of our numbers are real SIM numbers, and a few are virtual. If an app refuses a number, cancel it for a refund and try another country.

How do I pay?

Create a free account, then top up your wallet from $10 by card, crypto or the other methods shown at checkout. Numbers are paid from that balance, and unused balance stays for later numbers: it never expires, but it cannot be withdrawn. The price is held when you take a number and only charged once the Seis code arrives.
