Virtual number and SMS verification FAQ
Answers about numbers and codes, refunds, top-ups and bonuses, the API and your account.
Getting started
How do I receive an SMS verification code with a virtual number?
Sign up, add funds, then choose a country and a service on the order form. Enter the number in the app and the code appears on My numbers within the 20-minute window.
What is a one-time phone number?
A number you use for one verification and then let go. On tomnumber a number is yours for 20 minutes and receives SMS codes for the service you picked.
What is tomnumber?
tomnumber is a website for receiving SMS verification codes online with one-time virtual phone numbers, paid per number.
How do I create an account?
Pick a username of 4 to 20 lowercase letters and numbers that starts with a letter and has at least one number, enter a password of at least 8 characters twice, and add an email address for account recovery. Up to 3 accounts can be created from one IP address.
My service is not on the list. What now?
Search by the company name as well as the app name. If it is still missing, choose Any other app: it is meant for services that are not listed, in the countries shown on its page.
Numbers and codes
How long can I use a number?
20 minutes from the moment you get it. After that it is released and cannot receive new codes for you.
Can one number receive more than one code?
Yes. Every SMS for that service within the 20 minutes is shown, so a resent code appears too.
How fast do codes arrive?
That depends on the service sending it. Most apps let you resend after about a minute, and any code that arrives within 20 minutes is shown.
Which country should I choose?
One where the service is available, ideally matching the region of your account. After that, price decides; each service page shows every country's price.
Can I make calls or send SMS from the number?
No. Numbers receive SMS codes only.
Refunds
What if no code arrives?
The number closes after 20 minutes and the full price returns to your balance automatically.
Can I cancel a number myself?
Yes, as long as no code has arrived. The price goes back to your balance right away.
Is a number refunded after a code arrives?
No. Once a code is received the number counts as used, even if more codes come later.
Top-ups and bonus
Which payment methods are accepted?
Cryptocurrency through the payment window: USDT (TRC20, BEP20, ERC20, Solana), USDC (BEP20, ERC20, Solana), BTC, ETH, BNB, SOL and LTC. Cards, PayPal and bank transfers are not available.
What is the minimum top-up?
$50 per payment, up to $1,000.
How big is the top-up bonus?
$50 +6%, $100 +10%, $200 +15%, $400 +20%, $700 +25%, $1,000 +30%. It applies to every top-up, not only the first one.
When does a top-up show in my balance?
After the payment window confirms the payment on the network. The time depends on the coin's network.
Can I withdraw my balance?
No. The balance is for buying numbers, and refunds always go back to the balance.
API
Can I use tomnumber through an API?
Yes. Create a key under API key in your account. The API covers balance, services, prices, getting a number, status and cancel.
Are API prices different?
No. The API uses the same prices, balance and refunds as the website.
Is there a request limit?
Up to 120 requests a minute per key.
Safety and account
Is it safe to sign up with a virtual number?
It works well for verification. For accounts you plan to keep, add your own number or an authenticator app afterwards, because the virtual number is released after 20 minutes.
How is my password stored?
Only as a scrypt hash. Nobody at tomnumber can see your password.
I forgot my password. Can it be reset?
Email tomnumber@gmail.com from the address you signed up with. We confirm it matches your account and help you set a new password. Passwords are stored only as a hash, so nobody can read your old password.
