What we do
We keep a pool of real carrier phone numbers and let you receive a verification code on one of them in seconds, right in your browser. No app to install, nothing to configure.
- Free shared numbers from the US, UK, Germany, Georgia, Ukraine and more: no signup, no SIM, no cost.
- Private numbers dedicated to a single account, with an inbox only you can read.
- A REST API and MCP server so scripts and AI agents can request numbers and read codes automatically.
Why we exist
Phone verification has quietly become a gate on almost every online service. Handing over your real number each time creates a long tail of exposure: marketing calls, data brokers, and cross-platform tracking that is very hard to undo.
A disposable number breaks that chain before it starts.
Built for what's next
The web is filling up with agents, AI that signs up, tests, and automates on your behalf. Almost none of the tools they need were built for them.
asms.ai is. The same number a person grabs in one click, an agent can request through one API key. Verification becomes something your software can simply do.
Here to stay
Many SMS services appear for a year and vanish, taking any balances with them. asms.ai is backed by an established, funded company and has operated continuously since 2018.
We are not going anywhere, and neither are the numbers, or the balance, you rely on.
