# The right sender for every message.

Long codes, short codes, toll-free numbers, and alphanumeric sender IDs — provisioned, registered, and routed through one endpoint. The sender you send from decides throughput, cost, and which compliance regime applies.

## Four sender types, one API.

Numbers are the foundation of the Bird SMS API. Search availability, buy a number, and route inbound to a webhook with the same client you already send with. Which type you pick depends on volume, geography, and how much registration you can take on.

## Search, buy, and route in a few calls.

Find a number by country and capability, buy it, and point its inbound traffic at a webhook — all from the same SDK you send with. The number is live as soon as any required registration clears.

## Registration, handled where it's required.

Most US application traffic needs A2P 10DLC brand and campaign registration; toll-free needs verification; many countries require sender-ID pre-registration. Bird runs each of these from the dashboard, and the compliance surface tracks status from the API.

## Provision the right number, route it in minutes.

Numbers are one capability of the Bird SMS API: sending, two-way inbound, compliance, routing, and analytics ship with it.
