An OTP, or one-time password, is the short numeric code a service texts to a phone number to prove you control it, usually as part of signup or two-factor login. Most services will not let you finish creating an account without receiving and entering that code, which is why a working phone number is the first thing you need.
On asms.ai the flow is three steps. First, search the list above for the service you are verifying, such as WhatsApp, Telegram, or any of the 1,800+ services in stock. Second, pick a number type: VoIP High Quality for the lowest price, or a UK (+44) or Australia (+61) number for country-specific signups. The price is shown right next to each service. Third, a private number is allocated to you. Paste it into the service, and the SMS with the code appears in your inbox, usually within seconds.
VoIP High Quality numbers cover the large majority of signups at the lowest price, so they are the right default when you are not sure which to choose. Some services run strict checks and reject VoIP numbers outright, including banks and some messaging apps. For those, try a UK number, or rent a private non-VoIP number, which usually stands a better chance. If a code does not arrive, you are refunded automatically, so you only ever pay for codes that actually land.
Usually within seconds of the service sending it. The code appears live in the number's inbox, with nothing to install.
VoIP High Quality is our lowest-priced pool and works for the large majority of signups. We also carry UK (+44) and Australia (+61) numbers for country-specific signups, and a UK number is worth trying when a strict service, such as a bank or messaging app, refuses VoIP. For a non-VoIP line, rent a private number on the Numbers page. The exact price is shown next to each service, since it varies by service and number type.
You are refunded automatically. You only pay for codes that actually arrive, with no subscription and no wasted top-up.
Yes. A clean REST API and a native MCP server let scripts and AI agents pick a service, request a number, and read the code on their own.
No. The inbox of a paid number is private to your account, unlike the free shared numbers, whose inboxes anyone can view.
