Dispute evidence file requirements
Last updated: April 2, 2025
Schemes impose their own file limits for evidence you submit to challenge a dispute. If you submit evidence that does not comply with the scheme's requirements, they may reject it.
To streamline the evidence submission and review process, keep the evidence files short and highlight information relevant to the chargeback reason. For example, if the dispute was raised due to canceled merchandise, only submit the section of your cancelation policy that the customer violated and highlight relevant details.

You can use third-party compression tools to reduce file sizes to meet the scheme's requirements.
