How to Find Your Device Account Number (Last 4 Digits)
To identify the specific 4 digits that merchants see during a transaction, follow these steps on your iPhone:
Open Settings.
Tap Wallet & Apple Pay.
Select the specific Credit Card you used.
Go to the Info tab.
Tap Card Information.
Check the 4 digits displayed under Device Account Number (or "Apple Pay").
Important Information on Transactions
Merchant View: The last 4 digits of your Device Account Number are what appear on your transaction history and what merchants see, not your physical card's last 4 digits.
Unique Assignment: Each card added to Apple Pay is assigned its own unique Device Account Number per device.
Security: This process ensures your actual credit card details are never shared with the merchant during a purchase.
