Assessment basis: Individual business-category assessment. This is an editorial category assessment, not a bank’s rating, an individual merchant decision, a forecast of losses or a promise of approval.
How we assess risk & source references ↗No specific high-integrity-risk flag is reproduced here from the reviewed Visa classification section. This is not an exemption or a finding that no other requirements apply.
Questions worth preparing
- What goods or services generate the largest share of your sales?
- How and when do customers pay, and when are products or services delivered?
- Does a more specific network classification describe your actual business?
Your provider may also ask about transaction size, monthly volume, refunds, disputes, customer locations and delivery timing. Use your actual business facts when discussing the code.
