Duplicate Contact Overload

For some reason, my contacts list has exploded. I have one phone number in my contact list over 1,000 times. In all, I have 22,348 contacts in my phone. Clearly, there is something wrong! How can I delete the duplicates quickly?

Hello,
What happened just before this behavior started? Did you do an OS update? Did you integrate a new account to your device? Something else?
Are the contacts OK on the email server? If so, then you could simply remove the account from the device and reintegrate, which will refresh the data from the server to the device.
Good luck and let us know!

Need help to acheive Duplicate Contacts detector

Hi All,
I need to develop a feature in which my app would detect all the duplicate contacts of the user. A user can have many contacts. App shall find all his contacts which match on the basis of email, name and mobile number.
I am quite confused as what can be the logic here? Where should I do this work? Should I do it in a stored procedure or will something work in Java. I am using Hibernate as the ORM tool. Can I use some of the features of hibernate for this problem?
If I go by simple algorithm then I would probably have to make n database requests where n is the number of contacts.
Any help will be highly appreciated.
Regards,
Nitin

You can certainly do it in a stored proc.
Unless you are going to do it a lot then it doesn't matter.
Although "many" might come into play there. 10 is nothing. 100,000 is.

I currently use an iPhone, an iPad, and a Mac computer for business. The three devices have Contacts Managers that sync with each other through both Google and through Mobile Me. Currently, this has created a mess of duplicate contacts. Please advise me on the steps necessary for removing these duplicates and establishing a syncing solution that doesn't regenerate the duplicates. There are several applications available that remove duplicates, but I am not sure which ones work or don't work. I want information on this, but most importantly I want to understand how to fix this problem permanently. Also, I read somewhere that Mac's new operating system, Lion, can help deal with duplicates. I don't have Lion, but I would be willing to get it, if this would fix the problem.

Had the same problem with 4 devices (two computers, an iPhone and an iPod). The solution is simple: open the Address Book application in your mac, ask it to locate duplicate entries (under one of the top menu items, "edit" I think), and then ask it to consolidate them: it took me all of three seconds after I figured it out: worked like a charm! PS: if you have more than one mac with unconected Address Books, repeating the operation in the second one may be a good idea.

Report to show duplicate contacts

We have duplicate contacts in CRMOD. Is there a way to create a report that will show me all of the duplicates?
Thanks,
Sharon

Create a Report with following fields:-
Contact Full Name, Temp Column.
Edit the Temp column Formula and add COUNT(Contact."Contact Name" BY Contact."Contact Name"). On the Temp column add the filter is greater than 1.
Thanks

How can I add duplicate contacts on my iPhone

I know that the majority of related Qs on here are about deleting duplicated contacts; and yes that can be a pain, but I want to go the other way.
After I have spent ages filling in all the contact ino for someone [workwise etc], I often need to have another person from that same organisation. OK, so the name and SOME info is different, but at least 50% is relkative.
Can I duplicate the original entry and then amend the copy to get the new contact without just entering the WHOLE thing again ?

Thank you randers4 for answer above. I highly recommend using the info. in the two apple links below:
Archive or make copies of your iCloud data - Apple Support and

How to Delete duplicate contacts in the messaging app?

I set up a new email account, and was trying to send my contacts to the new account. In doing so I did not get the contacts to sync with the new account, but they did duplicate in my contacts app and my messaging contacts app. I can not find a means to delete the duplicate contacts in the messaging app. I stopped by Verizon at Best Buy, and they told me that there is no way to delete the contacts once they are in the messaging app. I can't believe that.
There must be a way to remove the contacts from the messaging app. Please help.

Hi Tidbits,
I ended up going to Best Buy, where I got my LG G3 Verizon phone. The Tech tried everything to correct the duplication, but could not find how to do it. He deleted everything, and went back to factory settings. Darn if the duplicates didn't come back.
He went to my Verizon account, and went to the Verizon Cloud. Clicked on Contacts, and there were all the duplicate contacts. He deleted the duplications, leaving the original for each contact. BINGO the problem was solved.
I am using the Standard Messaging instead of Verizon messaging Plus. The Tech said that if I had been using Using Verizon Messaging Plus this may not of happened. I just down want the added cost of Messaging Plus.
Thanks for the response.

Remove you icloud contact information on all your IOS devices, go to the icloud setting on you ios device and turn off the addressbook syncing, when it asks you "do you want to remove keep the address on your ips device you say NO... So now your MacBook is the only thing syncing too the icloud.

Deleted duplicate contacts from icloud and want to sync updated contacts to iphone and ipad?

Can anyone help with this?
Deleted duplicate contacts from icloud and want to sync updated contacts to iphone and ipad? Did it on icloud cause have duplicates on ipad and iphone also

Check icloud.com to be sure you contact list is correct there. If it is, just go to Settings>iCloud on your device and turn Contacts to On to sync the contacts to your device. If contacts are already set to On and you still see duplicates, you may be viewing a duplicate contact group in addition to the iCloud contacts. Open Contacts, tap Groups, then tap any groups other than iCloud to uncheck them, then tap Done. See if the duplicates are still there.

How do I get rid of the duplicate contacts on my iPhone?

I just transferred my 3Gs apps and data to my new iphone5. The contacts are now duplicated (a few times each) and are not identical. I am using OS X version 10.8.2 with itunes and icloud.
Any ideas how to merge or remove the unwanted contacts? What causes this duplication?
Any input would be appreciated!

Duplicate contacts is usually caused by user error due to syncing between iTunes and iCloud simultaneously. Turn off sync between either iCloud or iTunes and the duplicates should be removed.

Duplicate Contact/Address Book entries on iPhone

why do I have duplicate contact and address books entries on my iPhone? I never had this problem until I upgraded to iCloud. I have an iPhone 4 and it is upgraded to the current OS.

If you are using Outlook 2011, make sure you have the latest service pack and update.
Make sure your Mac Book and all devices have the latest update.
If the Calendar on the Mac Book is correct go to step 3
Assuming Mac Book Calendar is correct, remove accounts from iPhone, iPad.
Reconnect account to iPhone, iPad account.
All calendars should now be in sync.
There are times when the Mail, Calendar, Contact application has been corrupted (Outlook 2011, Mac Mail, Entourage, etc). This will cause all kinda of issues on your devices. You have to repair the mail client first. In the case of Outlook you can delete the profile and recreate it. In Mac Mail you can rebuild (from Tools on the menu bar)

TS4147 Syncing contacts only through iCloud with Outlook 2007 and iPhone & iPad I have duplicate contacts only on the iPhone & iPad. If I remove one of the duplicates the other one is also removed. A solution would be appreciated.

Go to contacts on your phone/ipad, click groups, make sure that the only checked contacts are icloud. That shoud do.
