Zuora can use the following identifiers:

• PAN (primary account number) - The 16‑digit card number collected from the payer and stored securely in Zuora.
• Gateway payment method identifier (gateway token) - The gateway‑generated ID returned after a successful PAN‑based transaction.
  • It is specific to a single gateway.
  • It is not a real card number.
• Network token - A 16‑digit surrogate card number issued by the card network, obtained via Worldpay’s token provisioning service.
  • It is tied to the merchant and the card.
  • It is gateway‑agnostic within the set of gateways where Zuora supports network tokens.
