When you sign up with Apple, Apple may create a private relay email for your account instead of using your real email. It looks like a random string of letters and numbers, like 2dgjmgh6hx@privaterelay.appleid.com.
This is an Apple privacy feature. Any email we send to that address gets automatically forwarded to your real email — so you still receive everything from us — but the address itself is what's on file in our system.
To find your relay email:
Option 1 — Easiest, if you can still log in:
Open the Split Pay app and sign in with Apple
Go to your account settings
Your email on file shows there
Option 2 — From your Apple ID:
Go to appleid.apple.com and sign in
Select Sign-In and Security
Choose Sign in with Apple
Find Split Pay in your app list
Under "Hide My Email," you'll see your Apple Relay Email for Split Pay
Save that relay email somewhere safe — you'll need it any time you contact support or need to recover your account.
If you can't find it either way, get in touch with us and we'll help you locate your account.
