Claude wants a phone number, and it does not take no for an answer. No code, no charge: nothing is billed for a number that stays silent. So borrow one — choose a market in SMS For U, give the number to Claude, and the Claude code arrives in your account by itself, seconds after Claude sends it. 1,400 services sit in the same catalogue, with numbers from markets across Europe, the Americas, Asia and Africa.
How you get your code
- Start in SMS For U by looking up Claude.
- The app lists the countries open for Claude at this moment; choose one of those.
- Say yes, and a working number is on your screen immediately.
- Hand that number to Claude at the phone step right after you enter your e-mail, then trigger the code.
- Watch it land in SMS For U by itself, and paste it back where Claude asked.
Why a phone number is asked for
Claude 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. Claude asks for it on the sign-up form, before the account exists at all. The number goes in at: the phone step right after you enter your e-mail. Claude normally asks for the number once and does not come back to it afterwards.
What the code looks like
Claude sends a short numeric code by SMS. The message from Claude arrives in your account unaided — no refreshing, no forwarding, and no second device involved in reading the Claude code. Claude expires its codes quickly — type it in while it is fresh. One number normally carries one Claude account.

Common questions
How do I get a Claude verification code without my own SIM card?
Open SMS For U, search for Claude and pick a country. You get a real phone number, you enter it at Claude (the phone step right after you enter your e-mail), and the code Claude sends appears in your SMS For U account by itself. No SIM card is involved, and the Claude number is not yours to keep.
How fast does the Claude code arrive?
The Claude code appears in your account within seconds of Claude sending it. How long Claude itself takes is up to Claude and to the country the number comes from, which is why nothing here is worded as a promise.
What happens if no Claude code arrives?
You do not pay for a Claude 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 Claude attempt costs nothing: no code, no charge.
Which countries can I use for Claude?
Claude numbers come from the 50 markets listed on this page. Which of them can be picked for Claude 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 Claude again later?
A used Claude number is not reserved for you indefinitely. Claude normally does not come back to it after sign-up, but if you need lasting access to the Claude account, use a number of your own.
