Finding the Serial Number for a Chirp

Since chirp serial numbers are considered confidential information and are unable to be registered, there is no serial number on the chirp itself. The device that set up the chirp will be able to view the serial number, while other GPS devices will require the last five digits of the unit ID of the device that programmed the chirp as a PIN to view the serial number.

To view the serial number (if using the device that programmed the chirp, skip steps 4 and 5):

1. Select Setup from main menu.
2. Select Geocache.
3. Select Program chirp.
4. Select Enter Pin.
5. Enter in the last five digits of the device's unit ID¹ that programmed the chirp.
6. Select Show Chirp Details.

The serial number will now appear, along with the number of visits and date of last visit.

¹ The unit ID can be found in the About section within the Setup menu.
