The Device Account Number created for your card when you add it to Apple Pay is unique to that device and used for secure transactions with Apple Pay.
This account number does not match the actual number of your virtual card and is used to avoid disclosing the actual number of your card during transactions.
To find the Device Account Number for your Apple Pay payzy card, follow these steps:
Open the ‘Settings’ app on your device.
Scroll down and select the ‘Wallet & Apple Pay’ option.
Select the payzy card you have added.
The number is displayed under the card information.
