# Send from your name, where it's allowed.

An alphanumeric sender ID puts your brand name in the from field instead of a number. Many countries require you to pre-register that name before it can deliver. Bird files the registration and reports its status through the API so you know when the sender is live.

## Why some senders need registering first.

Sender-ID registration is part of SMS compliance on the Bird SMS API. To curb spoofing, a number of countries only deliver alphanumeric sender IDs that have been pre-registered with the local carriers or regulator. Where that applies, an unregistered branded sender is rejected or rewritten. Bird files the registration for you and exposes its state, so you don't send into a sender that can't deliver yet.

## How registration works.

Where it's required, who files it, and when it's live.

## Check a registration's status from the API.

You file the sender ID from the dashboard; the API tells you where it stands per destination. Read the registration and branch on its status before you send from that sender.

## Registration follows the alphanumeric sender.

This is the compliance step behind alphanumeric sender IDs. The sender type lets you send from a brand name where the country allows it; registration is what makes that name deliverable where the country requires it first.

## Register your sender ID, then send branded.

Sender-ID registration is one regime of SMS compliance on Bird. File from the dashboard, track approval through the API, and send from your brand name where it's allowed.
