Does Dexcom G7 have a sensor code?

Dexcom G7 is factory calibrated. Unlike G6 sensors, the G7 sensors are pre-programmed with the factory calibration setting so you don’t need to enter a sensor code. However, you will still need to enter the 4-digit pairing code provided on the body of each new G7 applicator to pair a sensor to your compatible smart device* or receiver.
