How to change your Apple ID and email addressNeed to change the email address associated with your Apple ID? Here's how.
Your Apple ID is your gateway to all of Apple's cloud services: iTunes, Apple Music, and iCloud. But what about your actual username? It's usually an email address: Often, it's an @icloud, @me, or @mac address — but you might also have signed up with your third-party email account, like @gmail.com.
If you want to change the email address associated with your Apple ID, you can do so from a web browser. For the most part, it's simple.

Never fear: We'll walk you through the steps of changing the email address associated with your Apple ID and help troubleshoot some common problems.
