US Phone Number for SMS Verification
Get a one-time number from the United States for one SMS code. TwoLine US numbers are for a single verification, not for keeping. Prices are live and availability changes with stock.
Get a number See live prices, no account needed.
Best fit
US app signups, marketplace accounts, contact forms, and any service that asks for a US number once. You get one code on a US number, and then the number ends.
Price and duration
Prices are live and start at $0.39. They vary by app, country and line, so a US number has no fixed price. You see the exact price before you pay, with no account needed, and it comes out of your balance only when you buy. A number lasts long enough for one code: usually 10 to 20 minutes, sometimes shorter. The order page shows the exact end time.
Acceptance caveat
Availability of US numbers is live and not promised, and strict banks and regulated financial services are not sold on TwoLine at all. Apps can refuse a number because of its carrier type, its history, the country, your device, or a policy change. TwoLine does not publish its own delivery measurements. The methodology page explains what the prices and supplier-reported rates on the site mean.
Setup checklist
Before you buy: read the guide for your app, confirm the account will never need another SMS on this number, and be ready to enter the code. Right after signup, add email recovery and an authenticator where possible. Do not use a one-time number for any account you must not lose.

Choose the right number type
| Need | Better fit | Why |
|---|---|---|
| One low-stakes SMS code | TwoLine | One number for one code, a live price first, and the full price back in your balance if no code arrives. |
| Future SMS for days or months | Your own SIM or a kept-number service | A one-time number cannot be kept, renewed, or reused for later logins. |
| Outbound calls and voicemail | Calling-focused second-line app | TwoLine receives one code. It is not a phone service. |
| Bank, tax, healthcare, government, high-value crypto | Real SIM | Regulated and identity-critical accounts should never depend on a one-time number. |
This split keeps the product honest. TwoLine is not a replacement for every phone service, and it is not a number you can keep. It is the simple option for people who need one code on a number that is not their own, and who will never need that number again.
Pre-purchase checklist
- Decide whether future SMS may matter. If yes, do not buy a one-time number.
- Search for your app, then pick a country and a line. Countries vary by app and change with stock.
- Read the app-specific receive-SMS guide before you buy.
- Review the live price, then check the end time on the order page.
- After the code, add email recovery and authenticator-based two-factor authentication where supported.
- Remember that the number cannot receive future codes. Use your own SIM for accounts you must not lose.
The checklist is deliberately conservative. It reduces lockout risk and stops a cheap SMS decision from becoming a recovery problem later.
Availability, stock, and timing
Stock can move quickly. A number that is available when a guide is written may be out of stock later, and a country that is out of stock can return after restock. TwoLine should be read as a live product, not a static catalog promise.
Before you buy, check the current price and stock in the search. If an app or country shows no stock, do not plan the account around it until stock returns. Prices are live and start at $0.39, and they vary by app, country and line.
Buy the number only when you are ready to request the code. A number usually lasts 10 to 20 minutes, sometimes shorter, and the order page shows the exact end time. Give yourself time to receive the code and set up backup recovery right after.
Policy and safety notes
Use TwoLine for legitimate privacy protection, testing, one-off signups, and receive-SMS verification. Do not use one-time numbers for spam, fraud, ban evasion, harassment, regulated identity, or services where the terms require a personal carrier number. TwoLine does not sell numbers for banks, payment apps, money transfer, crypto exchanges, securities accounts, or government identity services. Those are refused at checkout.
Balance is not cash and buys numbers on TwoLine. If no code arrives by the end of the window, the full price returns to your TwoLine balance automatically. You can also cancel and get the refund after 2 minutes. Once a code has been delivered the purchase is final. Read the refund policy before you buy.
TwoLine or a kept number?
Need one SMS code and will not need the number again? Use TwoLine. Need a number you can keep receiving SMS on for days or months? TwoLine cannot do that. Use your own SIM or a kept-number service.

FAQ
How much does a US number cost?
Prices are live and start at $0.39. They vary by app, country and line, so there is no fixed US price. Search for your app and you will see the live price before you pay, with no account needed.
Will a US number work for every app?
No. Apps decide for themselves whether to accept a number. They can refuse one based on carrier lookup, number history, device reputation, country mismatch, or policy changes. If no code arrives by the end of the window, the full price returns to your TwoLine balance automatically.
Can I keep the same US number?
No. One number is for one code. It cannot be kept, renewed, or reused for later logins. That makes it the wrong choice for any account that may need a future SMS.
