It happens every single time you move. You’re sitting on your couch, trying to order a pizza or buy those sneakers you've been eyeing, and Safari suddenly insists you still live at that apartment you left three years ago. It is maddening. You’d think a trillion-dollar company would make this seamless, but honestly, learning how to update home address on iPhone autofill feels like navigating a digital labyrinth where the walls keep shifting.
The problem isn't just one setting. It’s a spiderweb. Your iPhone pulls data from your Contact card, but Safari also remembers things, and Apple Maps has its own opinion on where "Home" is. If these three things aren't in sync, you’ll keep seeing that old address pop up like a ghost from your past.
Let's fix it.
The Contact Card: The "Brain" of Your Autofill
Most people assume there's a specific "Autofill Menu" in Settings that handles everything. There isn't. Not really. Your iPhone's identity is tied directly to your personal contact card in the Contacts app. If that card is outdated, your phone literally doesn't know who you are or where you live.
Open your Contacts app. Right at the very top, you’ll see your own name with a little subtext that says "My Card." Tap that. This is the holy grail of your device's data.
Hit Edit in the top right corner. Scroll down until you find the address section. If you see your old address there, delete it. Seriously, don't just add the new one—trash the old one. iPhone's AI is sometimes a bit too helpful and might offer both if you keep the old entry, leading to those annoying "Which one?" prompts when you're in a rush. Type in your new street address, apartment number, city, and zip code.

Once you hit Done, your phone starts a background process to update its internal database. But wait. Don't close the app yet. You need to make sure the phone actually knows this specific card belongs to you. Go to your main Settings, scroll down to Safari, and then tap AutoFill. Ensure "Contact Info" is toggled on and that "My Info" is actually pointing to the card you just edited. Sometimes, after an iOS update, this link gets severed or points to a duplicate contact. It's a mess, but checking this saves hours of frustration.
When Safari Won't Let Go of the Past
Even after you fix your contact card, Safari might still betray you. Why? Because Safari caches form data. It remembers what you typed into websites previously, independent of your official contact card. This is why you'll see a greyed-out suggestion that is just plain wrong.
To kill these ghosts, you have to be a bit aggressive. Go to Settings > Safari. You’ll see an option for Clear History and Website Data.
Now, I know. You don't want to lose your open tabs or your login sessions. I get it. If you want to be more surgical, go into Settings > Safari > Advanced > Website Data. You can actually swipe left on specific sites where the wrong address keeps appearing and delete just that data. It’s tedious. But it works.
Apple’s machine learning, specifically the "Siri Suggestions" engine, also plays a role here. It watches your behavior across apps. If you frequently receive mail at a certain address or mentioned an address in a recent Note, Siri might "suggest" it in an autofill field. It’s trying to be smart, but it’s often just intrusive. You can toggle this off in Settings > Siri & Search, though most people find that overkill.

The Apple Maps Factor
This is the sneaky one. You’ve updated your contact card, you’ve cleared Safari, but when you go to ship a package, the phone still defaults to the old neighborhood. This often happens because Apple Maps still thinks your "Home" pin is at the old house.
Open Apple Maps. Swipe up on the search handle to see your "Favorites." You’ll see a house icon labeled Home. Tap the "i" or the "More" button next to it.
- Tap Change Address.
- Input the new location.
- Delete the old "Home" favorite if it lingers.
Why does this matter for autofill? Because iOS uses "Significant Locations" to verify your identity. If your phone sees you spending 10 hours every night at a location it doesn't recognize as "Home," it creates a conflict in the system’s logic. By aligning your Maps "Home" with your Contact Card "Home," you’re essentially telling the operating system, "Yes, I am sure this is where I live now."
Third-Party Apps and the Keychain Headache
We can't talk about how to update home address on iPhone autofill without mentioning iCloud Keychain. This is the encrypted vault that stores your passwords and credit card info. Sometimes, your address is attached to a specific credit card stored in your "Wallet & Apple Pay" settings.
If you’re checking out on a site and the shipping address is right but the billing address is wrong, that’s a Keychain issue.

- Open Settings.
- Tap Wallet & Apple Pay.
- Tap on your primary credit card.
- Look for Billing Address.
- Update it here.
Changing it in your Contacts won't always change it in your Wallet. Apple treats financial data with a higher "wall" of security, so you have to manually confirm that your billing address has moved along with your physical body. It’s a safety feature, but man, is it a chore.
Common Misconceptions About iPhone Autofill
People often think that if they change their address on their Apple ID via the website (https://www.google.com/search?q=appleid.apple.com), it will magically fix their iPhone. It won't. That changes your legal billing address for subscriptions like iCloud+ or Apple Music, but it doesn't necessarily push that data down to the Safari autofill engine on your local device.
Another weird quirk? The "Shared with You" feature. If a spouse or roommate sends you a contact card with your own name but an old address, your iPhone might get confused about which "version" of you is the real one. Check your Contacts for duplicates. If you see two versions of yourself, merge them. Always keep the one that is linked to your iCloud account as the primary.
Actionable Steps for a Clean Slate
If you've done everything above and things are still wonky, here is the "Nuclear Option" that usually clears the pipes:
- Toggle Autofill Off/On: Go to Settings > Safari > AutoFill. Turn everything off. Restart your phone (the actual "Slide to Power Off" restart). Turn it back on. This forces the system to re-index your contact card.
- Update Your "Me" Card: If you have multiple email accounts (Gmail, Outlook, iCloud) synced to your phone, make sure they aren't all fighting over which contact card is the "Me" card. Go to Settings > Contacts and check the My Info selection.
- Check Chrome: If you use Google Chrome on your iPhone instead of Safari, none of the steps above will work. Chrome uses your Google Account data. You’ll need to go into the Chrome app settings, tap Addresses and More, and update it there.
The reality is that iOS is a collection of legacy code and modern features layered on top of each other. Updating your address isn't just about changing one line of text; it's about updating the five different databases that Apple uses to track your location. Once you align your Contact Card, your Maps Favorites, and your Wallet Billing info, the autofill "ghosts" finally disappear.
Final Verification
After you've finished these steps, open Safari, go to a random retail site, and tap on a "Shipping Address" field. You should see your new address appear in the predictive text bar above the keyboard. If it's there, you've successfully updated the system. If it’s still showing the old one, double-check your "My Card" in Contacts for any hidden "Previous Address" labels that might be lingering in the notes or secondary fields. Remove them entirely to ensure the AI doesn't have any old data to latch onto.
You're now set for your next online order without the fear of your packages heading to your old front porch.
