X9 and PCI SSC Create Unified Pin Acceptance Security Standards

Unified PIN Standard Viewed as a Win for the Payment Industry

WAKEFIELD, Mass. and ANNAPOLIS, Md., Jan. 21, 2020 – In response to industry feedback, the Accredited Standards Committee X9 Inc. (ASC X9) and the PCI Security Standards Council (PCI SSC) have completed a joint initiative to create one unified PIN Security Standard for payments stakeholders.

In 2018, ASC X9 entered into a long-term partnership with the PCI SSC to combine the X9 TR 39 technical report with the PCI PIN Security – Requirements and Testing Procedures standard, the latter to be the surviving document. Over the next months, members of X9 and the PCI SSC worked together to merge the two documents. The combined document is version 3.0 of the PIN Security – Requirements and Testing Procedures standard, which was approved in August 2018. X9 will continue to partner with the PCI SSC on future versions of the standard.

Since all recent work had been directed to the PCI SSC standard, X9 TR 39 became out of date, and X9 has approved its withdrawal from publication. The PCI SSC standard can be downloaded from the PCI website at no charge. Reporting requirements previously contained in X9 TR 39 can now be found in the PCI SSC’s Template for Report on Compliance.

The goal of this joint initiative was to create a single PIN security standard and assessor qualification program to be managed by the PCI SSC. The PCI PIN Assessment Working Group, made up of representatives of X9, the PCI SSC and payment brands, collaborated to ensure that the resulting standard satisfies both PCI and X9 requirements.

“This is a significant win for the payments industry in that we now have greater clarity and consensus around a single PIN standard. We were very pleased to work collaboratively with ASC X9 on this important challenge,” said PCI SSC Senior Vice President Troy Leach. “Our two organizations have always enjoyed a strong working relationship, and this is yet another example of us coming together to advance better payment security. The outcome of this effort is a simplified PIN standard and assessor program process for payment card industry stakeholders.”

X9 Executive Director Steve Stevens said, “Our two organizations can be very proud of the results of our ongoing partnership through the PCI PIN Assessment Working Group: the unification of X9 TR 39 with the PCI PIN Security Standard. This document contains the best of both its predecessors, and it will enable the highest level of security at the lowest possible cost. We look forward to continuing this effort into the future to ensure that the standard continues to meet the needs of the financial industry user base.”
