Where Can I Find My Collar's Serial Number? – Halo Collar Help Center

Environment:

Answer:

There are a few ways to locate the collar's serial number:

- On the collar: Find the white label on the back of the Collar
  - - Note: It will be located under the QR code and underneath the Strap
- In the app: Go to Settings > Collars and the serial number will be underneath the collar name
- On the box: As a last resort, you can look for your collar's serial number on the outside of the box your order came in. This is the last recommended method because occasionally, collars are shipped in a box that does not match the serial number on the collar.

Note:

The serial number should start with either 20, 21, or 22, then an "H" and ends with a "-RT"
- For example "21-h1234567-rt"
