Temporary phone number
A temporary phone number is any line you use briefly and then give up. Four different products share the name — a one-time activation, a rental, a prepaid burner SIM and an eSIM — and they are not interchangeable. Most people asking for one want the first: a number that receives a single verification code and disappears, from €0.07 here.

Which temporary number does what
The honest comparison. Cost figures for the two rental columns depend on the window you pick; the activation price is live.
| Option | You keep it for | Receives | Costs | Use it for |
|---|---|---|---|---|
| One-time activation | One verification, up to 20 minutes | SMS from the one service you chose | From €0.07 per code | Signing up once, at any volume |
| Short rental | 4 hours to 1 day | Repeated SMS from one service | Priced per window, paid up front | A signup that sends more than one code |
| Long rental | 1 week to 12 months | One service, or every sender | Per window; all-senders costs about 85 % more | An account you must not lose access to |
| Prepaid SIM (burner) | Until the credit or the line expires | Everything, including voice calls | Handset, SIM and airtime | Real contact with real people |
| eSIM | The length of the plan | Everything, on your own phone | Monthly, per plan | Travel data and a second personal line |
| Free public inbox | No control over it at all | Whatever arrives, in public | Free | Nothing you would mind losing |
The vocabulary, briefly
The words are used loosely, and the differences between them matter more than the labels suggest.
- Temporary number
- The umbrella term. Any line you hold for less time than you would hold your own — minutes, days or months.
- Disposable number
- A number meant to be used once and abandoned. In practice that is a one-time activation: it exists for a single verification and is released straight afterwards.
- Burner number
- Borrowed from prepaid handsets. People mean either a physical prepaid SIM bought with cash, or — more often now — a rented line they can drop without consequence.
- Rental
- The same number kept for a fixed window, from four hours to twelve months, receiving repeatedly from one service or from every sender.
- eSIM
- A downloadable profile that adds a second line to your own phone. Excellent for data and calls abroad, and the most expensive way there is to receive one code.
- Second-number app
- A line provisioned inside someone else's application. Convenient, but the ranges are well known to the services that score them, and you keep the number only while you keep paying.
Which one you need
You are signing up once and will not be asked again
A one-time activation. It is the cheapest option by an order of magnitude, and releasing the number afterwards costs you nothing because you are never going to need it again. This is the right answer for most signups.
The service will ask for the number again
A rental. Messengers re-verify on every new device, exchanges ask again at withdrawal, and recovery flows send the code to the number on file. If the account matters, keep the line for as long as the account exists.
Somebody is going to call the number
None of the online options. A receive-only line passes signup and then fails the first time a driver, courier or support agent dials it. Buy a prepaid SIM and put it in a handset.
You want a second personal number on your own phone
An eSIM, or a second-number plan from your carrier. Verification numbers are built to receive one message and be recycled; they are the wrong shape for a line you hand out to people.
What a temporary number will not do
- It will not make an account permanent. A number released back to the pool can be reissued to someone else, and a service that texts it later is texting a stranger.
- It will not defeat domestic-only verification. Platforms that check national subscriber records refuse foreign ranges structurally, whatever the delivery rate says.
- It will not place or receive calls. These are receive-only SMS lines; voice fallback exists on some services and rentals, and never as a general phone number.
- It will not hide you from anyone with legal authority. Activations are logged, paid from an identifiable balance, and disclosed when a lawful request requires it.

Frequently asked questions
In practice, none. Both describe a line used for a single purpose and released afterwards. Disposable emphasises that you never get it back, which is exactly what a one-time activation does.
Not quite. A burner is traditionally a prepaid SIM in a handset, which can take calls. A virtual number is hosted and receives SMS only, but it is available in seconds and costs cents rather than the price of a phone.
A one-time activation lasts for a single code, up to 20 minutes. A rental runs from four hours to twelve months and can auto-renew before it expires.
You can register, and thousands of people do daily. The catch is re-verification: both ask for the number again on a new device, and a released number cannot answer. Rent the line if the account matters.
Rarely in the bank's home market, where virtual ranges are treated as a fraud signal. Delivery is better where the service is still expanding, but plan for refusal rather than around it.
It is quarantined and then returned to the operator pool for another activation. That is why nothing that needs long-term access should live on a one-time number.
