When a campaign ends, releasing the tracker stops the billing for its tracking numbers. Your call history stays.

### Open the Tracker's Settings

Go to your **Trackers** page and click the manage icon in the Manage column for the tracker you want to release.

### Release the Tracker

Press the red **Release Tracker** button at the top of the settings page. You'll be asked to confirm, because this cannot be undone.

Releasing will permanently:

* **Remove all tracking numbers** attached to the tracker.
* **Stop forwarding calls** to your destination.
* **Release the numbers for good** — they go back to the carrier.

### What You Keep

**All call history and reporting for the tracker stay available.** Past calls, recordings, transcripts, tags and values remain, and the tracker continues to appear in your reports for the periods it was running. Releasing ends the number, not the record.

### The Part That Catches People Out

**You cannot get the number back.** Once released it returns to the carrier's pool and may be reassigned to someone else. If the number is printed on anything still in circulation — a vehicle, a sign, a business card, an old brochure — those callers will reach whoever holds it next.

Release numbers you have advertised offline only when you're confident the advertising is out of circulation.

### Billing

Tracking numbers are not billed pro rata. A number released mid-month is still billed for the current period, then drops off the next invoice. See [An Overview of Call Tracker Billing](https://help.calltracker.io/hc/ct/articles/an-overview-of-call-tracker-billing).
