I lost my Dexcom ONE+ sensor code. What do I do?

You need the pairing code to use your Dexcom ONE+ system. The 4-digit code and the QR code are printed on the applicator. If you lose your applicator prior to pairing your sensor with the display device, you will have to use a brand-new sensor.

Do not use a code from a different sensor or make up a code. If you do, your sensor will not work as well and could display inaccurate data.
