# Tracking numbers vs. destination numbers: what's the difference

Nimbata uses two different types of phone numbers to power call tracking.
Understanding the difference helps you set up tracking correctly and avoid routing issues.

### 1. Tracking numbers

[Tracking numbers](https://app.nimbata.com/tracking/numbers) are the numbers your customers **see and call**. 
They are provisioned by Nimbata and used exclusively for tracking. They:
* Are assigned to pages, listings, campaigns, or sources
* Capture attribution data like source, medium, and campaign
* Forward calls to one or more destination numbers
* Appear in call logs, analytics, and reports

### 2. Destination numbers

[Destination numbers](https://app.nimbata.com/tracking/destinations) are your actual business phone numbers
tHEY receive calls forwarded from tracking numbers. They:
* Can be mobile, landline, VoIP, or call center numbers
* Do not track attribution on their own
* Can be reused across multiple tracking numbers
* Control where calls are routed

### How they work together

| Every tracked call in Nimbata follows the same path: Caller > Tracking Number > Destination Number

This separation lets Nimbata track performance correctly while still delivering calls to your existing setup.
