Kwai asks for a phone number before it lets you in. No code, no charge — a number that never receives one costs you nothing. You choose the market, we hand you a real number, and whatever Kwai texts to it appears in your SMS For U account within seconds of Kwai releasing it. The same catalogue covers 1,400 services and buys numbers on four continents.
How you get your code
- Look Kwai up in the SMS For U catalogue.
- Take a country from the ones the app is offering for Kwai today.
- Confirm the order; the Kwai number is live from that second.
- Type it in at the phone-number step during sign-up on Kwai and ask to be sent the code.
- The code turns up in your SMS For U account unprompted — copy it into Kwai and you are through.
Why a phone number is asked for
Kwai is a single login with a lot behind it, so the number is how it proves it is you and how you get back in. Kwai asks for it on the sign-up form, before the account exists at all. The number goes in at: the phone-number step during sign-up. Kwai normally asks for the number once and does not come back to it afterwards.
What the code looks like
Kwai sends a short numeric code by SMS. The message from Kwai arrives in your account unaided — no refreshing, no forwarding, and no second device involved in reading the Kwai code. The window Kwai allows is short, so do not leave the code sitting in your account. One number can usually serve more than one Kwai account, although Kwai may limit that.
What can go wrong
Kwai accepts numbers from many countries but not from all of them. Which countries work for Kwai changes over time, because Kwai adjusts its checks and because the available ranges of numbers change. That is the honest state of it — we can hand you a number, we cannot make Kwai take it. Read none of this as Kwai committing to anything. We keep success numbers off the page on purpose: they age faster than the page does.
Countries we serve
Below are the 50 markets we hold numbers in, Kwai included. Treat them as our footprint rather than as today’s shelf: ranges run dry and are topped up again while you read this, so a market listed here may be unavailable for Kwai within the hour. The country screen in the app is where that question is answered honestly for Kwai, because it is the only thing that updates as fast as the ranges do.

Common questions
How do I get a Kwai verification code without my own SIM card?
Open SMS For U, search for Kwai and pick a country. You get a real phone number, you enter it at Kwai (the phone-number step during sign-up), and the code Kwai sends appears in your SMS For U account by itself. No SIM card is involved, and the Kwai number is not yours to keep.
How fast does the Kwai code arrive?
The Kwai code appears in your account within seconds of Kwai sending it. How long Kwai itself takes is up to Kwai and to the country the number comes from, which is why nothing here is worded as a promise.
What happens if no Kwai code arrives?
You do not pay for a Kwai number that brought no code. Cancel the order in the app and the payment is refunded as soon as the cancellation is confirmed. That is the whole rule, and it is why a failed Kwai attempt costs nothing: no code, no charge.
Which countries can I use for Kwai?
Kwai numbers come from the 50 markets listed on this page. Which of them can be picked for Kwai at this moment is on the country screen in the app: that list moves through the day, and a page in a search index cannot keep up with it.
Can I use the same number for Kwai again later?
A used Kwai number is not reserved for you indefinitely. Kwai normally does not come back to it after sign-up, but if you need lasting access to the Kwai account, use a number of your own.
