This Device Is Already Associated With an Apple ID

Because you've done one of these things on an account : View and remove your associated devices in iTunes - Apple Support

Your iPhone, iPad, iPod touch, Mac, PC, or Android phone automatically associate with your Apple ID and iTunes when you:

• Sign in to Apple Music with your Apple ID.
• Download music to your iPhone, iPad, or iPod touch in the Music app to listen to when you're offline.
• Turn on iCloud Music Library.
• Download past purchases that you made in the iTunes Store, App Store, or iBooks Store.
• Turn on Automatic Downloads for iTunes Store, App Store, or iBooks Store purchases.
• Turn on Family Sharing.
• Subscribe to iTunes Match.

You also said you have 2 Apple IDs.

If you have 2, you may have accidentally signed in with the "other" one. By doing this, you have triggered the 90 day timeout, as was pointed out earlier in the conversation.

Do you have a question about the message ? The message means what it says, the device is already associated to an account and you can't use auto-downloads (nor iTunes match or iCloud Music, nor redownload a different account's purchases) on a different account until the 90 days have completed : View and remove your associated devices in iTunes - Apple Support

I have the same problem , I only have one ID and it tells me that my phone is already associated to another ID when i try to download my music on my phone. I paid for this membership on apple music and I can't even use it haha .

Either you, or somebody who has used the phone, has associated the phone to another account. If it's been associated to the account for more than 90 days you could ask the person whose account it is to log into the account and remove the phone from their account, or try contacting iTunes Support and see if they can/will remove it

No nothing of that happened , I downloaded the beta of ios 11 and then restored my phone for a fresh ios 11 install so when I put my apply ID and then tried to go and download my music it said that my phone was associated to another ID .

I only have 2 apple ID one if for my iphone 4 one is for my iphone 6 but I did not use my other phones ID so im guessing its a bug with the beta ios so I reverted to ios 10 but still the same .

Downgrading from a beta won't remove an association. If you are getting a message that the phone (or iPad as this is the Using iPad forum) is associated to an account you could try logging into the account that it's associated to and see if you can remove it, try contacting iTunes Support and see if there is anything that they can / will do, or wait until iOS 11 is released and see if that fixes it - unless you are a developer you shouldn't be using beta software, and not on a critical device.

What are you talking about "unless im a developper" the beta is available for everyone .

Also I only have one apple ID so how exactly do you propose that I find which ID is associated to this phone.

This is my phone and I only have one ID no one else has access to my iphone

The membership or music has nothing to do with any device. It is permanently tied to whichever AppleID you used to purchase the content or subscription. Purchases are forever tied to the AppleID used when purchasing and have nothing to do with the device’s you own and use over your lifetime.

So if you purchased the music with the other AppleID, then that is the one you must sign in to the iTunes Store with to keep those purchases, on any device you own or use.

Maybe my english is bad or people here don't understand what they are saying.

When you want to download music from apple music you have to enable the Icloud music library and that is where the problem is ! When I try to activate it , it tells me that my phone is already registered with another apple ID .

Better now ?

The beta is public, but by definition it's beta and isn't ready for public release, and it shouldn't be installed on a primary device, and only developers should really be installing it - you install it at your own risk, knowing that it will have bugs, and knowing that you may end up with issues and/or an unusable device

how exactly do you propose that I find which ID is associated to this phone.

It will be an account that has been used on the device and done one of the specified things on it. But it might also be due to a bug in iOS 11 . If it doesn't show on the account(s) that you've used on it try contacting iTunes Support and see if they can / will do anything - which they might not be able to do.

This whole Apple ID lock when u transfer device is because all the people who are poor would make new Apple ID for there free 3 month trials or they would use a friends Apple ID to get free music instead of paying 10$ a month with screws it up for people who are like me and pay the money but now locked out of downloads thanks to the poor people

Im having this problem. It seems simple to login to my old id and remove my iphone from that account but when i try to login it wants to send a verification code to a very old phone number so I have to go though a lengthy verification process. Apple support has been absolutely no help all I want is to enable music downloads on my current account so i either wait the whole 19 days or hope the verification completes so i can get in the account.

I think this is what is going on. You can only restore from an iCloud backup so many times before you are locked out of your ID for 90 days - if you used another Apple ID on the device previously in order to download past purchases without paying for them again.

Look at this discussion.

Apparently some users have had success in contacting iTunes Store support when they run into this issue.
