What MCC 7399 covers
Merchant Category Code 7399 is the ISO 18245 identifier used by the card networks for business services (nec). Acquirers, issuers and regulators use this code to set interchange, scheme fees, fraud rules and reporting categories for every transaction your business processes.
Other business services not elsewhere classified. Choosing the right MCC is critical: an incorrect code can lead to higher interchange, surcharges, or, in regulated categories, declined transactions and account holds.
MCC 7399 includes a broad range of 'Business Services, Not Elsewhere Classified'. This can encompass services from environmental consultants, secretarial services, telephone answering services, and more specialised B2B offerings.
Ticket sizes and transaction frequency vary wildly, from one-off large consultancy projects to routine, smaller administrative supports. Many transactions are B2B, which often involves invoice payments or larger sums.
Chargebacks can occur due to 'Services Not Rendered' or 'Services Not as Described'. For high-value transactions, clear contracts and proof of service delivery are crucial.
B2B transactions often have longer dispute windows under scheme rules, up to 120 days from service date or transaction date. Visa's Integrity Risk Program or Mastercard's ECP could flag merchants if persistent service issues or consumer complaints surface, even if not explicitly consumer-facing.
Cardflo's sophisticated KYB onboarding and transaction monitoring solutions are critical for MCC 7399, enabling thorough risk assessment for diverse business models and continuous oversight to detect unusual activity, protecting both the merchant and the acquiring bank.

Common questions
How does the 'Not Elsewhere Classified' nature of MCC 7399 impact risk assessment?
The 'Not Elsewhere Classified' nature means acquirers must assess each merchant individually, as the risk profile can range from low (e. g.
, secretarial services) to high (e. g.
, some types of lead generation). Cardflo performs detailed KYB to accurately categorise and underwrite these varied business models.
Are B2B transactions in this MCC exempt from 3D Secure?
While 3D Secure is generally recommended for card-not-present transactions, B2B payments often quality for exemptions under PSD2's Transaction Risk Analysis (TRA) rules if they are low value, recurring, or initiated by the merchant (MIT).
Corporate cards also often have their own fraud prevention tools that may mitigate the need for 3DS or facilitate frictionless pathways.
What specific documentation should a 7399 merchant provide to mitigate chargeback risk for service-related disputes?
Merchants in this MCC should maintain detailed records of service agreements, contracts, project deliverables, communication logs (emails, meeting notes), and proof of service completion. For digital services, access logs or usage reports are valuable.
These documents are crucial for representment against 'Services Not Rendered' or 'Not as Described' chargebacks.
