How do I find my Dexcom G7 serial number?

Your Dexcom G7 Continuous Glucose Monitoring System (Dexcom G7) serial number is a 12-digit number used to identify your sensor. You can find it in several places:

• On the sensor packaging
• On the sensor applicator
• In the Dexcom G7 app
• In the Dexcom G7 receiver

Tip: Take a photo or screenshot of the serial number each time you start a new sensor. It can help you find it later and confirm when the sensor was inserted.

On the sensor packaging

Check the side of the sensor box. The serial number appears after the label (21).

On the sensor applicator

Turn the applicator over to find the back. The serial number appears after the label (21).

In the Dexcom G7 app

Open the app and go to Connections > Sensor to find the serial number, labeled SN.

If your sensor is not currently connected, the serial number may not appear. However, if you use an insulin pump, your Dexcom G7 serial number might still be visible in the pump’s app.

In the Dexcom G7 receiver

From the home screen, select Menu, then go to Information > Sensor > Session info. The serial number appears near the bottom of the screen, labeled SN.
