What will I need when contacting Tech Support to report a sensor issue?
To report a sensor issue and request a replacement under the Dexcom Sensor Replacement Policy, you will need the unique identifying number of your product, otherwise known as the Serial Number (or “SN”). The information below will help you locate the SN of your product generation as the SN of different generations are located on different components of the system or in different sections of the mobile app or receiver.
If you don’t have this information, your replacement will be considered a goodwill replacement and count toward your replacement limit within a 12-month period.
TIP: Snap a picture of the Serial Number on your sensor box, transmitter box, or applicator to ensure you can find it later should you ever need support.
