What Is a Virtual Number and What Is It Used For?
A virtual number is a real, dialable phone number that is not tied to a SIM card in a handset. It lives on an operator's network and delivers its messages to software instead — a dashboard, an app or an API. To the service sending you a code, it looks and behaves like any other number.
A virtual number (also called a temporary or rented number) is a real phone number that can receive SMS without being tied to a SIM card or a physical line. The number is registered on a carrier's network; you read whatever arrives at it from a dashboard in your browser or from the app. In everyday use the term almost always means one thing: getting the verification code an app sends at signup without handing over your own phone number.
Below: how it works, how it differs from a SIM, an eSIM, and a VoIP line, what popular services cost today, and when it will not get you through.
How does a virtual number work?
The flow is short and identical for every order:
- Pick a country. The dashboard lists 195 countries, Turkey included; the number's country code (+1, +44, +90) follows this choice.
- Pick a service. More than 700 are listed, from WhatsApp and Telegram to Instagram. Both the price and whether the number will be accepted depend on this choice.
- Coins are deducted. The price for that country and service pair is shown before you confirm, then comes off your balance.
- A number is assigned. The system attaches a real, currently available number to your account; you copy it into the app.
- The countdown starts. The order stays open for a fixed window, and the app has to send the code inside it.
- The code appears in the dashboard. When the SMS lands, the code shows on the order card; copy it into the app.
If no code arrives before the countdown ends, the order closes on its own and the coins go back to your balance automatically. There is no ticket to open; the refund runs by itself on every order that receives no code.
"One-time" means the number is yours only for that order. Afterwards it returns to the pool and may be assigned to someone else, possibly for another service. You cannot ask for the same number a month later, so add a backup email and any recovery codes as soon as the account exists. We cover the trade-off in one-time vs permanent virtual numbers.
Is a virtual number permanent or one-time? SIM, eSIM, and VoIP compared
The phrase "virtual number" gets used for three different products, so it helps to draw the lines clearly:
- Physical SIM card: Bought from a carrier with ID; makes calls, uses data, needs a monthly bill or top-up, and stays with you for years. Opening a line for one verification is expensive and slow.
- eSIM: The same SIM loaded onto the phone digitally. It still needs ID, a subscription, and a compatible device; good for a data plan while traveling, not for receiving one code.
- VoIP line: A permanent number that runs over the internet and handles calls and SMS. It carries a monthly fee, and many apps recognize VoIP ranges and reject them at signup.
- A virtual number on Vernum: A real carrier number rented for a single order window that only receives SMS. No subscription, no contract; you pay in coins, only for the order you place.
The most common mix-up is calls: a virtual number cannot make or receive voice calls, so the "call me instead" option some apps offer will not work; ask for the code by SMS. There is no mobile data either; the number never goes into your phone and exists only in the dashboard.
So a virtual number is the wrong tool for a banking app or an identity-linked government service, anything that expects the number to stay with you. The right fit is a service that verifies once and never asks again: a new social account, a one-off signup on a shopping site, an app you want to try.
What does a virtual number cost? Real prices for popular services (Vernum, August 27, 2026)
The table was pulled from the Vernum catalog on August 27, 2026; 1 coin = $0.01. "Cheapest country" is the one that asked for the fewest coins for that service at that moment, and the last column is the price of a Turkish (+90) number for the same service.
| Service | Cheapest country | Coins | ≈ USD | Turkish number |
|---|---|---|---|---|
| South Africa | 63 | $0.63 | 432 coins | |
| Telegram | South Africa | 42 | $0.42 | 360 coins |
| Canada | 6 | $0.06 | 42 coins | |
| Indonesia | 5 | $0.05 | 42 coins | |
| Discord | Angola | 4 | $0.04 | 4 coins |
| Tinder | Canada | 6 | $0.06 | 74 coins |
The catalog holds 195 countries and more than 700 services. What the table shows is that the price is set by the service and country pair, not by the number itself: a Canadian number is 6 coins for Instagram and 6 for Tinder, while WhatsApp's cheapest country, South Africa, is 63. WhatsApp and Telegram cost noticeably more than the other four services. A Turkish number is among the cheapest options for Discord at 4 coins and costs 432 coins for WhatsApp. Since coins are refunded automatically when no code arrives, a failed attempt in an expensive country does not drain your balance. Prices refresh hourly; the live list and stock are in the dashboard.
Coins are topped up through Google Play in the Vernum app; the web dashboard shows your balance and takes orders. There is no subscription or monthly fee on top of the coin price.
Can you open WhatsApp with a virtual number? Which services and which country?
Yes. WhatsApp is listed in all 195 countries and is one of the most ordered services. It is also more sensitive to the country you pick than most, so use the country list sorted by success rate to improve your odds of finishing on the first try. See the WhatsApp virtual number verification guide for a walkthrough and the WhatsApp virtual number page for the current country list.
The same applies to every other service. The dashboard covers social media (Instagram, TikTok, X), messaging (Telegram, Discord), shopping and rides (Amazon, Uber), gaming (Steam, Roblox), and finance (PayPal, Binance); if a service is in the list, you can get a number for it. The full list is on the services page.
When choosing a country, go in this order:
- Does the app require a country? If it expects a local number or signups from one region, satisfy that first.
- Start from the top. When you search for a service, countries are sorted by the success rate measured for it; codes arrive most often at the top.
- Compare the coin price. If success rates are close, take the cheaper one; a "cheapest first" sort is available too.
- Check stock. Skip a country with no numbers right now and move to the next.

When a virtual number does not work
A virtual number does not finish every signup on the first try. The four most common cases and what happens in each:
- The code did not arrive: When the countdown ends, the order closes and the coins are refunded automatically. Next time, pick the country one step down the list instead of the same one. For the reasons a code can get stuck on the app's side, see SMS code not arriving: fixes.
- The app rejected the number: Some services refuse certain country codes, or ranges they classify as virtual or VoIP, and show "this number is invalid." No code was requested, so the coins come back when the timer runs out; try another country on the next order.
- The number was already used on that service: Pool numbers are real carrier numbers, so someone may have used one on the same service before, and the app may say "already registered." No code will arrive, the refund applies, and a new order means a new number.
- The countdown expired: If you were slow to enter the number, the timer may have run out. The order closes, the coins return; open a new order and enter the number right away.
Some jobs are simply not for a virtual number: accounts that expect the number to stay with you, apps that verify by voice call, and services that will want a fresh code from the same number months later. Use your own line for those.
Frequently asked questions
Is a virtual number legal?
Using a virtual number is not illegal in itself; the number is a real carrier number and all you do is read the SMS that arrives at it. The limits are set by each app's own terms of service: some services restrict accounts opened with a virtual number. Use the number only for your own accounts.
Can you make calls with a virtual number?
No. A virtual number only receives SMS; it does not support incoming or outgoing voice calls, cannot use mobile data, and is never installed on your phone. An app's 'call me instead' option will not work with these numbers, so ask for the code by SMS.
How many times can a virtual number be used?
A virtual number is assigned for a single order window. Once the code arrives and the process is complete, the number returns to the pool and may later be assigned to another user; you cannot request the same number again afterwards.
What happens if the code never arrives, do I lose money?
No. If no code arrives within the countdown, the order closes on its own and the coins you spent are refunded to your account automatically. You can open a new order and try a different country.
Is a virtual number safe?
Once the order ends, the number is no longer tied to you; it cannot be tracked like a permanent line. The only thing to guard is the code itself: enter it only into the app you are signing up for and never share it with anyone. For accounts you plan to keep, add a backup email and two-factor authentication as well.
Is a virtual number a real phone number?
Yes. It is allocated from the same international numbering plan as any other number and routes through carrier networks the same way. The difference is where the message ends up: in software rather than on a SIM card in a phone.
Can a virtual number receive a call?
It depends on what the number was provisioned for. Numbers rented here are provisioned to receive SMS, so a service that falls back to a voice call reading the code aloud has no path to you — which is why the SMS route has to succeed within the window.
Does using a virtual number hide who I am?
It keeps your personal line out of the service's records, which is a real privacy gain. It is not anonymity: the number is allocated by an operator, and lawful requests to that operator reach the records behind it.
