Reason Code

A specific alphanumeric code assigned by a bank to explain the cause of a chargeback or dispute.

Updated March 1, 2026•3 min read

A Reason Code is a standardized value provided by the card issuer (the customer's bank) to explain exactly why a transaction is being disputed. Every Chargeback or Retrieval Request is accompanied by a reason code that dictates the specific type of evidence required to challenge the claim. Common categories include:

  • Fraudulent: The cardholder claims they didn't authorize the charge. This is the most common code and requires proof of identity or 3D Secure (3DS) authentication.
  • Product Not as Described: The customer claims the item was damaged or different than advertised. This requires proof of clear Unclear Product Descriptions.
  • Subscription Cancelled: The customer claims they were billed after cancelling. This requires proof of informed consent and clear Hidden Subscription Terms.

Merchants must tailor their Evidence Packets to the specific reason code provided to maintain Risk Confidence and improve their dispute win rate.

Why this term matters for Stripe account risk

Reason Code is not only a vocabulary item. It is a live risk signal that influences how Stripe evaluates dispute exposure, payout predictability, and verification confidence for your account. When this signal appears together with abnormal refund velocity, delivery uncertainty, or weak policy disclosures, account controls can become stricter. Treat Reason Code as an operational metric that should be monitored, documented, and explained with evidence.

Diagnostic signals to review weekly

  • Track trend direction, not just a single snapshot. A persistent rise is more important than one isolated spike.
  • Compare this signal with fulfillment timing, support response speed, and billing clarity to identify root causes.
  • Document the exact trigger conditions so your team can reproduce, audit, and resolve the issue consistently.
  • Escalate early when this term appears alongside dispute-heavy reason codes or repeated verification requests.

Practical actions to improve confidence

  1. Define an internal threshold and owner for this signal so actions are not delayed.
  2. Link this signal to a checklist in your operations workflow (checkout, fulfillment, support, and evidence retention).
  3. Update website disclosures and receipts so customer expectations match real delivery and billing behavior.
  4. Keep a short incident log with timeline, root cause, and remediation to support future platform reviews.
