You can have ten devices (no more than five computers) associated with your Apple ID for purchases at one time.

Can I use my Apple ID on multiple devices?

You can use a single AppleID on many devices, including 2 iphones. Note though that if you use the same AppleID for iCloud, iMessage, FaceTime then you are using a single account for those services. All devices using that AppleID share all messages, conversations, iCloud emails, contacts, calendars, phone logs etc.

Can I use same Apple ID for 3 devices?

Answer: A: Yes you can do it. I do it with 4 different devices all using the same Apple ID. You need to associate different email addresses for each device in order to use those email addresses as the “contact at” email address.
