Warning: Guest Checkout Tokenization is currently available only in India and will be rolled out to other markets in the future. Please contact your [Mastercard representative](https://developer.mastercard.com/mastercard-checkout-solutions/documentation/support/index.md#get-help) for more details on market expansion.

Guest Checkout Tokenization allows merchants and Payment Service Providers to tokenize PANs entered by consumers when performing guest checkout. Guest Checkout allows cardholders to make a purchase without the need to create an account or save their payment details with the merchant.
