Sudden disappearance of contacts on iPhone

Sounds frustratingespecially since you’ve already tried the main iCloud synch steps. If contacts have suddenly disappearedit’s probably due to a sync source issue rather than deletion. Here are some tips:

Go to Settings > Contacts > Accounts and check if you have multiple accounts (iCloudGmailOutlooketc.) Sometimes contacts are stored in a different accountand toggling iCloud wont affect those. Turn each account’s “Contacts” toggle off and back on one at a time to refresh.

Login to iCloud.com then press Contacts. If the missing contacts are therethey just aren’t syncing to your iPhone. Trying signing out of iCloud (iPhone Settings> your name > Sign Out) and back in.

On iCloud.comclick your name at the top then press Data Recovery and select Restore Contacts. You can roll back your entire contacts database to a previous date.

Open the iPhone Contacts app and tap Lists or Groups in the top left. Make sure all groups are checkedsome can be hidden because their group isn’t selected.

If none of the above workedit may be worth contacting Apple Support directly. They can check your iCloud server logs to see if there was a sync error.

Hello everyone! I have never posted before but I figured after successfully getting my contacts back it would be worth sharing with you all because this was VERY frustrating to say the least.

I found out after all of the previous options had failedyou must:

1. Go into your contacts settings
2. Click Contacts Accounts (which may include iCloudGmailOutlookExchange and any other email accounts)
3. iCloud should already have contacts selected so continue through the others
4. When I clicked into my other accountsthere was something at the top to click which said along the lines of "email not authenticated"
5. So basicallyyou must re-sign into each of your email accounts through the Contacts settings and then your contacts will basically start flowing back into your phone! (or at least mine did). And I did have to sign back into all of my accounts but this MUST be done through the contacts accounts settings

Hope this helps!!

After talking with an Apple tech and walking through a number of optionsthe final conclusion was that the missing contacts were linked to an old work email that I no longer have access to. Because they were never loaded to Icloudthe restore wouldn't recover them.

The fix would be to contact my previous employer to see if they can share a Vcard of my old contacts to reupload to my phone and then save under my personal email address.

It is unfortunate that the contacts were still showingeven though I no longer had access to the email account they were associated to.

Hopefully this helps,

I panicked when this just happened to me. All I did to fix it was go to phones icon on main screen. Click on contacts then hit lists in top left hand corner and then hit all contacts and they came back.

Me too. Tried all of the solutions given below. (Thank you!!) Then I had the bright idea to reboot my phone.

Duh. It worked :)

Does that happen to be when you were in college? I’ve just had this happen for my last 10 years of contacts. For years I’d periodically get these bizarre pops about logging into a Microsoft exchange account. From what I’ve read around the internet somehow all the contacts were very geniously saved to a (now) nonexistent student email account from the time I first added my student email to an iPhone 10 years ago. Even dumber is that it kept somehow saving every contact for at least 6 years after to a non-existent and not-logged-in account and suddenly with one of the recent updates has decided to no longer associate itself with wherever that information was (no doubt) locally stored.

Contacts are not stored locally. They are stored in whatever account you've chosen. You need to go to Settings>Apps>Contacts and check to make sure that your contacts are being saved to the proper account. I usually check this after a major updatejust in case.

I have concluded that this is what happened with my contacts; an old work email account that can no longer be authenticated. But I have family members contact info and other personal contacts that was lost having nothing to do with my work. Seems that Apple would have given notification or heads up before they took action that is now causing me quite a bit of time to re-enter those contacts.

Apple has no control over or knowledge of the status of your old work email. Once the account fails to authenticatethe data becomes inaccessible. Apple can't force your phone to retain data that doesn't belong to you. And once you stored those contacts in your work accountit became their data.

Make sure that you go to Settings>App>Contacts>Default and check to make sure that the default account to which contacts are being saved is on that is under your control.

I also face the same issue that happened from 7 to 8Sept2025.

I log into my 4 accounts and random contacts including all last contacts are missing on all of themiCloudMicrosoft personalGmail and Microsoft business.

I have a backup that’s is 3 months old in iCloud but I didn’t manage yet to restore due to missing spare phone. I wonder if it will bring back those deleted contacts up to my last backup 3 months ago. Has anyone tried a restore to previous backup? if yes did it resolve the issue? Did you manage to see all deleted contacts to the backup date?

On a side noteI see no logic on these deleted contactsI have contacts older then 5y ago deleted but also all recent contacts and I have no clue about a rational to justify this which is the worsthundreds people with same issue and no rational to explain it? Support can’t check update logs? I work with software teams and this is mind blowing! While a bug or human mistake are bad but at least it could justify this issuethe worst is still not knowing the root causeit totally shakes my trust over apple.

The issue is always caused by adding accounts to mail and failing to turn off all accounts except one (iCloud is my favourite) then moving all other account contacts to that one account.

Multiple contact accounts is a disaster waiting to happen.

Apple really showing what it means to be a trillion dollar company on this one 👍

I called Apple support about this same issue about a month ago and my inquiry was escalated to a supervisor who told me that their engineers are working on a solution and that I'll have to wait for an iOS update to come out. It's still a HUGE issue. I just texted someone in my contacts this morning and instantly his name disappeared and it just showed a phone number. Every day I'm having to create a new contact for people I've known for years. I get calls daily from phone numbers I don't recognizeso I have to let it go to voicemailthen re-create the contact and call them back once I realize they're a friend or biz contact. I've lost everyone's email and mailing addresses as well. FRUSTRATING.

I had the same issue and tried all kinds of things that were reco'd…. Glad I kept my old iphonebecause i just airdropped the old contact list into the new phone…. a bit of a PIA on duplicatesbut the point made. I at least now I know who is calling me!

Can’t believe this issue still hasn’t been fixed. I have around 1,000–2,000 contacts saved from 2019 until nowand NEARLY ALL of them just disappeared. I didn’t do anything unusual with my phoneand there was no notification at all. The contacts were simply goneleaving only 12 that I saved about two weeks ago.

I could lose my job because of this. It’s frustratinghopelessand disappointing.

And what cloud service were you syncing them with?

Have you checked to see if they still exist on the server?

Replying to several community members: I have tried everything to restore my contacts. Including speaking for hours with apple advisors on the phone and going to genius bar 4 times. The latte has told me they cannot fix the problem and basicallythat they are surprised I keep coming back for a fix. This tells me they are saying: go away and don't come back about this. One of the genius managers told me that when I sign up for iCloud and anything AppleI am signing up to leave Apple free of any responsibility when they loose data. Howeverand this is a big however: it would be appropriate for Apple to warn users that this is a continuing problem so that we can move to protect ourselves by getting our data off ICloud. Look at the Apple community complaints and you will see that users are complaining about this loss of contacts for much of August. I think it is connected to upgrading your current OS as Apple advises you to do. Once your contacts are moved to iCloudthey do not remain on your computer No one told me this before I signed up I would have gotten another backup like Verizon. NowI cannot even find them on my external backups. You cannot use Time Machine to recover your backups either. Alsothis kind of contact loss has been going on for years. I went to reddit and found folks complaining about this contact loss as far back as five years ago. Question: what can users do about this? Apple is not going to do anything. I think they lost the data and cannot recover it. That is why they let the data loss go on without warning their users. It is truly outrageous.

Happened to me too starting Aug 14. Sleptwoke up and suddenly realized hundreds of contacts were missing. The missing contacts are completely randomnothing in common or particular orderthe only relation I came to was MOST contacts from 2019 to 2023 and some from 2024.

Tried every possible solution mentioned here and elsewherenothing worked. Reached out to apple supportthey tried to walk me through every possible solution I already triedagain nothing worked. Now escalated to apple software engineering team.

Hoping to find a solution with Apple soon.

Hi There

I have spent a few hours on phone to Apple support Mon and Tues this weekstill no real results and they have indicated ludicrous things that it is linked to a work email I had 5 years ago. It all happened after an upgrade over weekend. I must say I am nervous about any future upgrades now. And when I went to icloud to use the back up before it happened it gave me nothing. So in essence I have been paying icloud storage for nothing. SMSs gonecontacts gone. My last iphone bought in Nov last year. They managed very clunkily I might add for the biggest tech co in the worldto restore from my old iphone but they still have 10months of info they can't get back and they said they would ring me back but haven't. I think it's too hard and they don't have an answer. My problem is this is my business so it REALLY affects me. They speak down to you too at Apple support. It feels like a culture there as I have now spoken to a few people with the same attitude. I just want answers and I don't believe them with what they think has gone on ie the link to the old work email from 5 years ago. Particularly with messages I read here on this community board where others have experienced something similar with no answers. What is particularly alarming is the steps they give to retrieve infoI believe has lost more info. So I noticed I lost the contact names to phone numbers yet the name appeared on an SMS. Then all the SMSs went and the names associated with them. I scroll down the SMSs and it takes me to messages from years ago. Anyway good to know there is a community to talk this through with.
