Your Apple ID is the most important piece of information in the Apple ecosystem. It’s the account you use to sign in to iCloud, the App Store, Apple Music, and more. But if you haven’t signed in for a while, it’s easy to forget which email address or phone number you used.
If you’re wondering, “How do I find what my Apple ID is?” don’t worry—there are several quick ways to check on your iPhone, Mac, or even via the web.
1. Check Your Settings on iPhone, iPad, or Apple Watch
If you are already signed into an Apple device, finding your Apple ID takes only a few seconds.
- On iPhone or iPad: Open the Settings app. Your name will be at the very top. Tap it, and you will see your Apple ID (usually an email address or phone number) listed right under your name and profile picture.
- On Apple Watch: Open Settings, then tap your name/profile.

2. Check Your System Settings on Mac
If you are using a MacBook or iMac, your Apple ID is stored in your System Settings.
- Click the Apple Menu () in the top-left corner of your screen.
- Select System Settings (or System Preferences on older macOS versions).
- Click on Apple ID (or your name) in the sidebar.
- Your Apple ID will be displayed prominently at the top.
3. Check Apple Apps (App Store, Music, or Messages)
Sometimes you might be signed out of iCloud but still signed into individual apps.

- App Store: Open the App Store and tap your profile icon (top right). Your Apple ID will be listed there.
- Messages: Go to Settings > Messages > Send & Receive.
- FaceTime: Go to Settings > FaceTime.
4. Search Your Email Inbox for Messages from Apple
Your Apple ID is almost always an email address. Search your various email accounts (Gmail, Outlook, Yahoo, etc.) for messages from Apple. Look for:
- Receipts for App Store purchases.
- iCloud storage bills.
- “Your Apple ID was used to sign in” notifications.
If you find an email from Apple addressed to a specific account, that account is likely your Apple ID.
5. Use the “Look It Up” Tool on the Web
If you don’t have your device handy or none of the steps above worked, Apple provides a lookup tool.
- Go to the Apple ID account page.
- Click “Sign In” and then click “Forgot Apple ID or password?”
- Click the “Look it up” link.
- Enter your first name, last name, and the email address you think you used.
- If you enter the correct information, the site will confirm your Apple ID.
6. Check if You Are Logged In on a Windows PC
If you use Apple services on Windows:
- iCloud for Windows: Open the iCloud app. Your Apple ID is usually visible under your name.
- iTunes: Open iTunes, click Account in the top menu, and select View My Account.
What if I found it but forgot the password?
Once you have identified what your Apple ID is, if you can’t remember the password, you can reset it at iforgot.apple.com. You will need to verify your identity using your trusted phone number or security questions.

Summary
Finding your Apple ID is usually as simple as checking the Settings menu on your iPhone or Mac. If your devices are locked or lost, the Apple ID Lookup Tool on Apple’s website is your best second option.
Pro Tip: Once you find it, consider adding it to a password manager so you never lose access to your digital life again!
