What MCC 5399 covers
Merchant Category Code 5399 is the ISO 18245 identifier used by the card networks for miscellaneous general merchandise. Acquirers, issuers and regulators use this code to set interchange, scheme fees, fraud rules and reporting categories for every transaction your business processes.
General merchandise retailers 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.
This MCC captures miscellaneous general merchandise stores that don't fit into more specific retail categories. Merchants here can vary widely, from novelty shops to pop-up stores selling various goods.
Ticket sizes and frequency are highly variable depending on the specific merchant's offerings.
Chargeback profiles for this MCC are eclectic; they can be low or moderately high based on the specific goods sold and the merchant's operational efficiency. Common reasons might include 'merchandise not received' for online orders or 'not as described.'
This general category typically does not have specific scheme monitoring programmes but can be flagged if individual merchant metrics deviate significantly.
Cardflo's flexible KYB and fraud monitoring solutions can adapt to the diverse business models within this MCC, ensuring tailored risk management.
Merchants in miscellaneous general merchandise must structure acceptance strategies reflecting their specific product mix and sales channels. For higher ticket items, implement 3D Secure 2 for online transactions and ensure clear delivery terms to prevent 'merchandise not received' disputes.
If offering a wide range of goods, a multi-acquirer setup through Cardflo can optimise routing based on item value or risk, particularly for cross-border sales, ensuring competitive rates. Reserve requirements might be adjusted based on the individual merchant's historical chargeback rates and product liability exposures.
Acquirer and acquirer assessment stance.
Low-to-medium-risk standard board, depending on the specific business model. Thorough underwriting is essential to assess product type, sales channels, and operational history.
Some cases may warrant closer monitoring or a reserve if initial risk factors are elevated.
Dispute and chargeback profile.
The most prevalent disputes here are "13.1 / 4853 (merchandise not as described)" and "13.2 / 4855 (merchandise not received)". "Not as described" often arises when product variations are not clearly communicated, or quality expectations differ.
Detailed product photos and descriptions are essential. "Not received" occurs frequently with online sales where tracking is absent or unreliable.
Proof of delivery, including signed receipts or courier tracking showing successful delivery to the cardholder's address, is the strongest defence.

Common questions
How does the 'miscellaneous' nature of MCC 5399 impact onboarding and risk assessment for merchants?
The broad nature of MCC 5399 means that acquirers perform more detailed due diligence during KYB.
Instead of relying solely on the MCC, the underwriting team will scrutinise the specific types of products sold, the sales channels (online, in-store, pop-up), average ticket size, and business history. This ensures the appropriate risk tiering and payment processing terms are applied.
What are common chargeback scenarios for miscellaneous general merchandise stores?
Given the variety, chargebacks can range from 'merchandise not received' (Mastercard 4855, Visa 13.1) for unique online items, to 'merchandise not as described' (Mastercard 4853, Visa 13.3) if the customer's expectation wasn't met. Fraud chargebacks (Mastercard 4837, Visa 10.4) can also occur.
Clear refund policies, detailed product descriptions, and reliable shipping are crucial for defence.
Can merchants in MCC 5399 easily transition to a more specific MCC if their product focus changes?
Yes, if a merchant in MCC 5399 evolves to primarily sell goods that fit a more specific category (e. g. , consumer electronics, clothing), they can request a change of MCC from their acquirer.
This typically involves submitting updated business details and may trigger a re-evaluation of their risk profile and processing rates, potentially leading to more favourable terms or specific industry programmes.
For miscellaneous general merchandise merchants with varying ticket sizes, how should they balance fraud prevention with customer experience?
Merchants selling diverse goods with fluctuating ticket sizes should implement a tiered fraud prevention strategy. For low-value transactions, focus on basic address verification and velocity checks to avoid friction.
For higher-value items, leverage advanced fraud tools, including pre-authorisation checks, 3D Secure 2, and IP address geolocation, which add security without unduly hindering buying.
A multi-layered approach, dynamically adjusting the level of scrutiny based on transaction value, historical customer data, and known fraud patterns, can strike an optimal balance between security and a smooth customer experience, thereby reducing chargebacks.
How can miscellaneous general merchandise merchants effectively manage and communicate diverse return policies across a broad product range?
Merchants with a wide product range should create a clear and easily accessible return policy that categorises items by their specific return conditions. For instance, 'perishable goods are non-returnable,' 'electrical goods within 30 days unopened,' and 'general merchandise within 14 days with proof of purchase.'
Displaying this policy prominently at the point of sale, on all receipts, and on their website is crucial. Consistent application of these policies by trained staff and clear customer service channels can prevent misunderstandings from escalating into disputes, building trust and reducing chargeback rates.
