Mastercard 4849

Questionable merchant activity

Mastercard 4849 is raised where a merchant appears in one of Mastercard's risk or compliance programmes. It is handled with the acquirer, not through an evidence submission.

We do not cover this code

This code comes from a Mastercard compliance programme, not from a cardholder claim. Talk to your processor rather than filing evidence.

Reply to your processor directly with what it asks for. We would rather say that than sell you a document that cannot help.
