I carry my iPhone almost everywhere, so it makes sense to prepare it for situations in which I may be unable to communicate. Learning how to set up Medical ID on iPhone for emergencies creates an accessible digital medical card containing critical health information and contact details.
A first responder or nearby helper can view this information from the Lock Screen without entering the device passcode. The setup takes only a few minutes, but entering accurate details, enabling access, and testing the finished Medical ID are essential.
What Does Medical ID Do on an iPhone?
Medical ID is a safety feature built into Apple’s Health app. It can display your name, date of birth, medical conditions, allergies, medications, blood type, primary language, emergency contacts, and other information that may help during an emergency.
A responder might use these details if you are unconscious, disoriented, injured, or otherwise unable to answer questions. Medical ID does not replace official medical records, a medical alert bracelet, or professional healthcare advice. Instead, it provides a quick summary that may help responders understand your immediate needs.
Allowing access does not unlock the iPhone. A person viewing Medical ID cannot open your messages, photos, apps, email, or complete Health records through the emergency screen.
How Do You Create or Update Medical ID in the Health App?
The Health app comes preinstalled on an iPhone and has a white icon containing a red heart. Menu wording can vary slightly by iOS version, but the basic setup process remains similar.
Open Your Health Profile
Launch the Health app and tap your profile picture or initials in the upper-right corner. Select Medical ID under the profile information. Tap Get Started if you have not created a profile before. If one already exists, tap Edit.
Enter Accurate Medical Information
Complete the fields that could be useful during urgent treatment. These may include your medical conditions, medical notes, allergies and reactions, current medications, blood type, height, weight, date of birth, and primary language.
Prioritize information that may affect immediate care, such as a severe medication allergy, seizure disorder, diabetes, heart condition, implanted medical device, blood-thinning medication, or communication requirement.
Check prescription labels or medical records before entering medication names and dosages. Never guess your blood type or add an unconfirmed diagnosis. An incorrect detail could create confusion at a critical moment.
Avoid entering Social Security numbers, financial details, passwords, insurance login credentials, or unrelated private information. Medical ID should contain a concise emergency summary rather than your complete medical history.
Add Trusted Emergency Contacts
Scroll to Emergency Contacts and tap the plus icon or Add Emergency Contact. Choose someone from the Contacts app and specify that person’s relationship to you. Repeat the process if you want to include another dependable contact.
Choose people who recognize your phone number, understand that they have been selected, and are likely to answer. Tell each person that they are listed and confirm that their saved phone number is current.
To remove someone later, return to Medical ID, tap Edit, and use the delete control beside the contact’s name. Confirm the removal and save the changes.
Enable Emergency Access and Save the Profile
Turn on Show When Locked. This setting allows someone to open the Medical ID card without knowing your passcode.
Next, enable Share During Emergency Call. Depending on the iOS screen, Apple may display a shorter label such as Emergency Call. In supported regions, this setting can share Medical ID information with emergency services when you call or text them from an iPhone or Apple Watch.
Review every field and tap Done in the upper-right corner to save the profile.
Should You Turn On Show When Locked?
Show When Locked makes Medical ID useful when you cannot unlock the phone yourself. However, it creates a privacy tradeoff because anyone holding the device may be able to view the details you chose to display.
Review the card carefully before enabling this option. Include information that could assist during an emergency while excluding anything you do not want accessible from the locked device.
Even with this option enabled, your passcode continues protecting the rest of the iPhone. The emergency screen only reveals the information stored in Medical ID.
How Does Share During Emergency Call Work in the US?
Share During Emergency Call can transmit Medical ID information to supported emergency services when you call or text for help. For US users, this feature may provide useful details during a supported 911 interaction, although availability can depend on the region, network, device, and local emergency system.
The feature may require Emergency Calls & SOS location access. To check it, open Settings, choose Privacy & Security, tap Location Services, select System Services, and make sure Emergency Calls & SOS is enabled.
Medical ID and Emergency SOS perform different jobs. Medical ID stores emergency health information, while Emergency SOS contacts emergency services and may notify the people you have designated.
For broader safety preparation, I also review how to enable government emergency alerts on iPhone so I can receive supported warnings about severe weather, public safety threats, and other urgent situations.
What Happens to Your Emergency Contacts After an SOS Call?
After an Emergency SOS call ends, your iPhone can send your emergency contacts a text message unless you cancel the notification. The message may include your current location. Contacts may also receive temporary updates if your location changes while the emergency-sharing status remains active.
Simply opening Medical ID does not call 911 or automatically notify anyone. A responder can manually tap a listed phone number to call that contact from the Medical ID screen.
How Can You Test Medical ID From the Lock Screen?
Testing confirms that the information is visible before an actual emergency occurs. Lock the iPhone, wake the screen, and open the passcode entry screen without using Face ID or Touch ID. Tap Emergency in the lower-left corner and then tap Medical ID.
On many newer iPhones, pressing and holding the side button and either volume button also displays emergency controls. If a Medical ID slider appears, use it to view the card.
Repeatedly pressing the side or power button may initiate an Emergency SOS countdown when that shortcut is enabled. For this reason, the passcode-screen method is safer for routine testing. Do not complete an SOS countdown or place a test call to 911.
Confirm that the card shows the intended medical details and correct contact numbers. If the Medical ID option does not appear, return to Health, open Medical ID, tap Edit, and confirm that Show When Locked is on.
Can Medical ID Be Viewed on an Apple Watch?
Medical ID can also appear on a paired Apple Watch. A responder can press and hold the watch’s side button and use the Medical ID control to view the available information.
After making an important change in the Health app, check the information on both devices. This extra verification helps ensure that outdated medications or contact details are not still displayed.
How Often Should You Update Your Emergency Information?
Review the profile at least once every six months. Update it whenever you start or stop medication, receive a diagnosis, identify an allergy, change your primary language, or replace an emergency contact.
I also recommend reviewing the card after a major iOS update. The information will generally remain saved, but checking the access and sharing settings confirms that everything still behaves as expected.
If the update causes unusual power consumption, understanding why your iPhone battery drains fast after an iOS update can help you identify background activity and settings that may need attention.
Frequently Asked Questions
1. Why should I learn how to set up Medical ID on iPhone for emergencies?
It provides responders with health information and contact details when you cannot communicate. Its usefulness depends on accurate information and enabled Lock Screen access.
2. Can anyone view Medical ID without my passcode?
Yes, if Show When Locked is enabled. They can view the Medical ID card, but they cannot use it to access the rest of the device.
3. Does viewing Medical ID alert my emergency contacts?
No. Opening the card does not send an alert. Contacts may receive notifications following an Emergency SOS call, or someone can call them manually from the card.
4. Does Medical ID work without cellular service?
Information saved for Lock Screen access can be viewed directly on the device without cellular service. Calling 911, sharing data, or sending contact notifications requires a supported emergency connection.
Final Thoughts
I see Medical ID as a simple but valuable part of emergency preparation. The most important steps are entering accurate details, selecting dependable contacts, enabling Lock Screen access, and testing the card without triggering an SOS call.
The information also needs regular maintenance. Reviewing the profile every six months can prevent an expired phone number or outdated medication from appearing when a responder needs reliable information quickly.
