Why a phone number is asked for

Numbers from Czechia carry the dialling code +420, so the service you are signing up to sees a Czech number and treats the account accordingly. A +420 number matters wherever a service varies its content or its shipping options by country, and it matters nowhere else — for a plain sign-up the only thing that counts is that the Czech number receives the SMS. You do not have to be in Czechia yourself: a +420 number is reachable wherever you are. Which services can be verified with a Czech number at a given moment changes through the day, because ranges of numbers are used up and refilled, so that list lives in the app rather than on this page.

Common questions

Do I have to be in Czechia to use the number?

Which services work with a number from Czechia?

What if no code arrives on my Czech number?

You do not pay for a Czech number that brought no code. Cancel the order in the app, and the payment is refunded once the cancellation is confirmed. There is no subscription: you pay per number, never per minute and never per month.

No code, no charge

You do not pay for a number that brought no code. If nothing arrives, cancel the order in the app; the payment is refunded as soon as the cancellation is confirmed. While it is being checked, the amount stays reserved rather than spent.

Cancelling is possible after a short wait at the start of an order — a number needs a moment before it can be reached at all, and a cancellation in the first seconds would be refused anyway.

If a number has already received one code and you need a second one, you can ask for another SMS on the same number. That is a separate, chargeable attempt and it is not refunded even if no second code arrives; the app shows what it costs before you confirm. There is no subscription: you pay per number, never per minute and never per month.

What this is not for

Do not use these numbers for banks, payment services, wallets or crypto exchanges. Those are excluded — and an account resting on a number that is not permanently yours is an account you can lose. The same goes for anything you need access to for years: government portals, tax accounts, insurance. A temporary number is for a one-off confirmation, not a lasting key to something important.
