# Caller ID
> Set up and manage outgoing caller ID names to increase answer rates and build trust with recipients
## Overview
An effective outgoing caller ID name helps you stand out and connect with your contacts more successfully. When recipients see your business name instead of just a phone number, they're more likely to answer your calls and trust the communication.
Caller ID name is exclusively available to paying customers who represent a business with a Tax ID and an approved US carrier registration. This feature is not available for personal use.
## Understanding caller ID
### How caller ID works
When you make a call, carriers reference authoritative databases to display your business name on the recipient's phone. This process involves:
1. **Database registration**: Quo, formerly OpenPhone, submits your caller ID information to national databases
2. **Carrier lookup**: Recipients' carriers pull your information when you call
3. **Display on device**: Your business name appears on their screen
If you've ever seen a caller's name without having them in your contacts, this is the same system at work.
