What to include in a Medical ID, and where to set it on iPhone and Android.

Here is a five-minute setup that could genuinely save a life. Both iPhones and Android phones can show medical information and emergency contacts right on the locked screen, where a paramedic or a good Samaritan can reach them without the passcode. Allergies, conditions, medications, and who to call — all available in an emergency when the person cannot speak for themselves. This guide walks you through setting it up on either kind of phone. No jargon. No judgment. No rushing.

Why This Can Save A Life

Picture the worst moment: someone collapses, alone or among strangers, and cannot speak. The information on their phone could guide the help they get.

In an emergency, seconds and facts matter. Knowing a person is allergic to a drug, or takes a blood thinner, changes how responders treat them. Having that on the lock screen means the information is there even when the person cannot say it themselves.

  • A paramedic can learn about allergies before giving a medication
  • They can see existing conditions like diabetes or heart trouble
  • They can call a family member listed as an emergency contact
  • All of it without needing to unlock the phone

What Information To Include

The Medical ID holds several kinds of information. Fill in what is relevant and would help a responder.

You do not have to fill in every field — put in what genuinely matters in an emergency. Allergies and major conditions are the most important. Emergency contacts are essential so responders can reach family quickly.

  • Medical conditions — diabetes, heart disease, epilepsy, and the like
  • Allergies and reactions, especially to medications
  • Current medications, particularly critical ones like blood thinners
  • Blood type, if known, and emergency contacts

Setting Up Medical ID On iPhone

On an iPhone, the Medical ID lives in the free Health app. Here is the step-by-step.

Take your time filling it in accurately. The emergency contacts are chosen from the phone's contacts, so make sure the family members you want are saved there first. Once done, the information is stored and ready.

  • Open the Health app (white icon with a red heart)
  • Tap Medical ID, then Edit
  • Fill in conditions, allergies, medications, and blood type
  • Add emergency contacts near the bottom
  • Tap Done to save

The Crucial Show When Locked Setting

This is the setting that makes the whole thing work. Without it, the Medical ID is hidden behind the passcode and useless to a responder.

With Show When Locked on, a responder can reach the Medical ID from the locked phone by tapping Emergency, then Medical ID. That is the whole point — the information available without the passcode. Do not skip this step, or the setup does nothing in a real emergency.

  • In the Medical ID edit screen, scroll to Show When Locked
  • Turn it ON
  • Also turn on Share During Emergency Call if offered
  • Save your changes

iPhone Emergency SOS

Beyond the Medical ID, the iPhone can call for help fast with Emergency SOS, and even share the Medical ID with emergency services automatically.

This turns the phone into a fast lifeline: a few presses and it is calling for help, alerting family, and sharing the medical details. Setting it up and practicing it once means it is ready if the frightening moment ever comes.

  • Pressing and holding the side and a volume button starts an emergency call
  • You can set it so pressing the side button several times does it too
  • When you call emergency services this way, the Medical ID can be shared
  • It can also notify your emergency contacts with your location

Emergency Contacts On iPhone

The emergency contacts you add do double duty — a responder can call them, and Emergency SOS can alert them automatically.

Pick contacts who are likely to answer and able to help — usually an adult child or spouse. Adding two or three is wise, so if the first does not pick up, a responder or the SOS feature can reach the next. Tell those people they are the emergency contacts.

  • In Medical ID, tap add under emergency contacts
  • Choose a family member from your contacts and their relationship
  • Add more than one if you can, in case the first is unreachable
  • Make sure those people know they are listed

Emergency Info On Android

Android phones — Samsung, Pixel, and the rest — have their own version, found in the settings. The idea is the same.

The exact wording varies a little by phone brand, but every modern Android has this under Safety and emergency. Fill in the medical details and contacts just as on the iPhone, and make sure the lock-screen option is on.

  • Open Settings and find Safety & emergency
  • Tap Medical information and fill in conditions, allergies, and medications
  • Add Emergency contacts from your contacts
  • Turn on the option to show this on the lock screen

Showing It On The Android Lock Screen

As on iPhone, the key is making sure the info is reachable from the locked screen. Confirm this setting on Android.

The whole value depends on a responder being able to reach the information without the passcode, so confirm the lock-screen option is turned on and then test it yourself. If you can find it from the locked screen, so can a paramedic.

  • Look for a show-on-lock-screen option in the emergency settings
  • With it on, a responder taps Emergency on the lock screen to see it
  • Test it by locking the phone and finding the emergency info
  • The exact path varies by brand, but the option is there

Android Emergency SOS

Android phones also have an Emergency SOS feature to call for help quickly, usually with a button press.

Like the iPhone version, this turns the phone into a fast way to summon help. Setting it up and knowing the button pattern — often five quick presses of the power button — means it is ready if a scary moment arrives.

  • In Safety and emergency, find Emergency SOS
  • It is often triggered by pressing the power button several times
  • It can call 911 and text your location to emergency contacts
  • Set it up and know the button pattern in advance

Smartwatch Fall And Crash Detection

If the person wears a smartwatch, it can add another layer — sensing a hard fall or a crash and calling for help on its own.

For someone at risk of falling, a watch with fall detection is a powerful companion to the lock-screen Medical ID. If they fall and cannot get up or reach the phone, the watch can summon help by itself. I compare these in my guides on fall detection devices.

  • An Apple Watch or some Android watches can detect a hard fall
  • If the person does not respond, it can call emergency services
  • It can share the Medical ID and alert emergency contacts
  • This works even when the phone is not in hand

Keeping It Up To Date

Medical information changes, and outdated info can mislead a responder. Keep it current.

An out-of-date Medical ID can be worse than none if it lists a medication the person no longer takes or misses a new allergy. Tie the update to something regular — a birthday, a New Year, or after each doctor visit — so it stays honest.

  • Update the medications whenever a prescription changes
  • Add any new condition or allergy as it comes up
  • Update emergency contacts if numbers or people change
  • Review it every so often, perhaps yearly

The Privacy Balance

Some people worry about having medical details on the lock screen. Here is a sensible way to think about it.

There is a fair balance: the critical facts that could save a life — major allergies, key conditions, contacts — belong on the lock screen, while routine private details can stay locked away. You control exactly what to include. For most people, the emergency benefit clearly wins.

  • Only include what would genuinely help a responder in an emergency
  • You do not have to list every private detail
  • The benefit in an emergency usually far outweighs the small exposure
  • The everyday pill schedule can stay behind the passcode; emergency facts go here

Low-Tech Backups Too

The phone is powerful, but a dead battery helps no one. A couple of old-fashioned backups round out the plan.

Paramedics are trained to check the fridge and wallet for medical information, and a bracelet is visible instantly. Pairing the lock-screen Medical ID with one of these low-tech backups covers the case where the phone is not available.

  • A medical alert bracelet or necklace noting key conditions or allergies
  • A wallet card with medications, conditions, and emergency contacts
  • A list on the fridge, where responders are trained to look
  • These work even if the phone is dead or lost

For Someone With Memory Loss

For a person with dementia, emergency info takes on extra importance, because they may not be able to explain their situation at all.

Someone with advanced memory loss may not know their own medications or be able to give a phone number. Having it all on the lock screen and on a bracelet means responders and good Samaritans can help and reach family even when the person cannot assist at all.

  • Note the dementia diagnosis so responders understand confusion
  • List medications and conditions they cannot report themselves
  • Include multiple contacts, since one may not be reachable
  • Pair it with an ID bracelet, since they may not have the phone

Testing That It Actually Works

A safety feature you have not tested is only a hope. Take two minutes to confirm the emergency info is really reachable.

If you can pull up the Medical ID from the locked screen, so can a paramedic. If you cannot, the Show When Locked setting is off — go back and turn it on. This quick test is the proof the whole setup works.

  • Lock the phone completely
  • On the lock screen, tap Emergency
  • Then tap Medical ID and confirm the information appears
  • Check the emergency contacts are listed and correct

If They Do Not Use A Smartphone

Not everyone carries a smartphone, and that is fine. The emergency information still needs a home — just a low-tech one.

For someone without a smartphone, the wallet card and the bracelet do the whole job the lock screen would. Paramedics are trained to check the wallet and the fridge, so keep the information there, clear and current.

  • A medical alert bracelet or necklace listing key conditions and allergies
  • A wallet card with medications, conditions, and emergency contacts
  • A clearly posted sheet on the refrigerator
  • A basic phone can still store emergency contact numbers

Questions People Ask

A few questions come up often. Here are the plain answers.
