# JPMC-PDP Documentation from https://developer.payments.jpmorgan.com # Authentication Each country or region has consumer protection regulations that may include cardholder authentication. Ensure that you are aware of these requirements and preferences, as authorization rates and processing costs could be impacted. The following table shows the supported authentication methods. **Supported authentication methods** | Authentication method | Description | | --- | --- | | Address verification service (AVS) | AVS contains consumer information sent within a verification or authorization request to the issuer. - The issuer validates the billing information and provides a result code in the response. - You should interrogate the result code in the response to ensure the consumer information submitted is correct before proceeding with the payment. - Not all regions or issuers support this service. | | Card verification value (CVV) | The CVV is the 3 or 4-digit value printed on the front or back of a payment card. - The issuer validates this code, and then sends back the card security result code in the response. - You should interrogate the card verification result code to ensure it indicates that the submitted CVV is correct before proceeding with the payment. - CVV is required for Canada eCommerce transactions. | | 3-D Secure (3DS) | The 3DS protocol allows issuers to directly authenticate cardholders prior to authorization and is required in some countries for e-commerce merchants. - After a cardholder is authenticated, 3DS response fields are included in the authorization request. - You should interrogate the 3DS response field results to ensure the cardholder authentication is a match before proceeding with the payment. | > Learn more about [3D Secure](/docs/commerce/online-payments/capabilities/online-payments/payment-enhancements/3d-secure) authentication. > ## Related [3-D Secure](/docs/commerce/online-payments/capabilities/online-payments/payment-enhancements/3d-secure) [Verify a payment](/docs/commerce/online-payments/capabilities/online-payments/how-to/verify-payment)
