Create an emergency Medical ID
A Medical ID provides information about you that may be important in an emergency, like allergies and medical conditions. Your Apple Watch can display this information so that it’s available for someone attending to you in an emergency.
Tip: Having an emergency Medical ID that includes your date of birth is particularly important for those who are 55 and older. Apple Watch SE and Apple Watch Series 4 and later include fall detection, which is turned on by default if you’re 55 and older (and can also be turned on for anyone 18 years or older).
Set up your Medical ID
Open the Health app on your iPhone.
Tap your profile picture at the top right, then tap Medical ID.
Tap Get Started, then enter your information.
View your Medical ID on Apple Watch
On your Apple Watch, hold the side button until the sliders appear.
Drag the Medical ID slider to the right.
If you don’t see your Medical ID when you hold the side button on your Apple Watch, open the Apple Watch app on your iPhone, tap My Watch, tap Health, tap Medical ID, tap Edit, then turn on Show When Locked. To hide your Medical ID when your Apple Watch is locked, turn off Show When Locked.
Tip: Add emergency contacts to your Medical ID, and your Apple Watch alerts them if it makes an Emergency SOS call to emergency services. See Make an emergency phone call on Apple Watch.
