Why is an email address required for Dexcom account setup?
Dexcom sends out important educational and support information covering your first 10 days with your new CGM system. So even if you’re using your mobile number to create and verify your account, Dexcom asks for your email address and sends an email verification. Please verify your email as soon as possible, so we can get you the information you need to use your system safely and effectively.
