Last Updated on November 4, 2021 by Corepay

Announcements from major credit card companies have been frequent in 2021. With the adult content revisions announced earlier this year, we have now met another significant update.

This article will break down the edits and what it means for customers regarding Do Not Honor.

Mastercard has announced they are introducing two new issuer Do Not Honor edits to their Data Integrity Monitoring Program. Mastercard will begin monitoring issuer declines with these changes, specifically with the response code 05, Do Not Honor (DNH), in efforts to ensure response code 05 doesn’t make up more than five percent of an issuer’s card-not-present (CNP) declines per month.

Visa has also announced that they are rolling out a similar program that targets Do Not Honor.

So, What Is Mastercard Doing?

They will be monitoring issuer submission of the response code within data element 39 for 05 DNH CNP declined transactions over five percent of all CNP declines in authorization request response/0110 and financial transaction request response/0210 messages.
