The 27 services
Choose the service first, then a country. Numbers are matched to the service, so a number for one service is a different purchase from a number for another.
The “What to know” column only repeats what the service itself says in its official help or terms. A dash means we found no specific official statement, not that the service will accept the number.
| Service | Type | What to know |
|---|---|---|
| Messaging | WhatsApp’s terms ask you to register with your current mobile number and to update it in the app if it changes. Plan how you’ll receive later codes. | |
| Telegram | Messaging | Mobile numbers only. Telegram says whoever has the number has the account: turn on two-step verification and move to a number you keep. |

Not offered as one-time codes
Signal and bank or payment-service verification are not sold as one-time codes. If you choose them in the app, it says so and points to a DualLine line as a possible alternative, which can’t guarantee acceptance either.
Price and availability
There is no single price list. The price depends on the service and the country, and the app shows it before you pay. Stock is live, so a country may have no number for a service at a given moment; the app shows what is available right now.
The price is taken from your DualLine credit when you place the order. If no code arrives, the full credit returns to your DualLine balance automatically. If a code arrives, the order is complete, even if the service then refuses the number.
Acceptable use
One-time codes are for verifying your own account. The DualLine terms forbid using the service to obtain or intercept verification codes or accounts without authorization, to misrepresent your identity or to break platform rules, and reasonable limits may apply to codes and account creation.
In practice: register only your own account; no bulk or automated sign-ups; don’t use a number to get around a ban or a platform’s limits; never try to access an account that belongs to a number’s previous user; and follow each service’s own rules.
The services’ rules point the same way. WhatsApp forbids creating accounts through unauthorized or automated means. Viber’s terms forbid creating multiple or false accounts, and buying, selling or renting access to an account. Telegram forbids using its service to send spam or scam users.
Your take-away checklist
- Choose the service before the country.
- Read what the service says about virtual numbers.
- Check the price and availability shown in the app.
- Verify only your own account.
- Follow the service’s own rules.
- Plan how you’ll receive future codes.
Common questions
Why isn’t Signal on the list?
Signal isn’t offered as a one-time code. The app explains this when you choose it and suggests a DualLine line as a possible alternative, without guaranteeing acceptance.
Does a service on this list guarantee the number will work?
No. The list shows which services you can order a number for. Each service decides whether to accept it; if no code arrives, the credit is returned automatically.
Why is there no price on this page?
Prices change with the service, the country and current availability, so the app shows the live price before you pay.
Which countries are available?
Availability is live and differs by service. The app shows the countries that currently have a number for the service you chose, with the price.
Can I use one-time codes to create several accounts?
No. One-time codes are for verifying your own account. Bulk or automated sign-ups are against the DualLine terms, and many services forbid multiple or false accounts.
