Visa and Mastercard Have Cracked Down on Miscoded Transactions

What High-Risk Merchants Need to Know
If you’re operating in a high-risk industry, like cannabis, nutraceuticals, adult, or firearms, you’ve probably heard the phrase “miscoded merchant account” tossed around more than once. Maybe you’ve even used one. But in 2025, relying on that workaround has become a liability.
Visa and Mastercard are cracking down hard on miscoded transactions, and if you’re not paying attention, your merchant account could be frozen, or worse, terminated without notice.
Let’s break down what’s happening, why it matters, and what you can do to stay compliant without compromising your revenue.
What Is a Miscoded Transaction?
A “miscoded” transaction happens when a merchant’s business type (known as an MCC, Merchant Category Code) is inaccurately classified. For example, a cannabis dispensary might be listed as a “health and wellness” business to get approved for a merchant account, even though cannabis remains federally illegal.
This tactic has been used in:
- Cannabis (posing as CBD or wellness)
- Adult content (labeled as education or media)
- Firearms (misclassified under sporting goods)
- Nutraceuticals (filed as general retail or supplements)
While this used to be a gray area, it’s now a red flag for card brands.
Why Visa and Mastercard Are Cracking Down
In 2025, Visa and Mastercard rolled out stricter monitoring protocols to identify mismatched MCC codes and high-risk merchants flying under the radar. Their concern? Fraud, money laundering, reputational risk, and non-compliance with federal regulations.
Key reasons for the crackdown:
- Regulatory pressure from lawmakers and international watchdogs
- Chargeback spikes in miscoded accounts
- Cardholder complaints leading to higher fraud ratings
- Increased oversight on payment facilitators and ISOs (Independent Sales Organizations)
They’ve invested heavily in AI-based tools that scan transaction metadata, website content, and shopping cart behavior to ensure the MCC matches the actual business model.
What Happens If You Get Caught?
The consequences of miscoding can be severe:
- Immediate merchant account termination
- Frozen funds (up to 180 days)
- Permanent placement on the MATCH list (a blacklist for merchants)
- Loss of processing privileges across all providers
- Reputational damage that can affect future partnerships
This isn’t theoretical, it’s happening.
Common High-Risk Industries Affected
Visa and Mastercard’s enforcement has hit several verticals especially hard:
- Cannabis & Delta-8: Despite legality in many states, cannabis is federally restricted. Merchants miscoded as CBD or wellness are being shut down.
- Adult Entertainment: MCCs that don’t match explicit content are getting flagged by site crawlers and AI review tools.
- Firearms & Ammo: Misclassified firearms merchants are losing accounts overnight as card brands require proper MCC usage.
- Nutraceuticals & Supplements: Selling “miracle cures” or unapproved claims under general retail codes is no longer tolerated.
What Can You Do Instead?
1. Get Properly Underwritten as High-Risk
Work with a processor that specializes in high-risk verticals (like Signature Payments). You’ll pay slightly higher fees, but keep your account.
2. Use Accurate MCC Codes
Don’t hide your business model. Apply under the right MCC. It builds trust and reduces risk of shutdown.
3. Choose a Processor That Understands Compliance
High-risk processors work directly with sponsor banks that allow these industries. They know how to structure accounts legally and securely.
4. Explore Alternative Payment Methods
Use ACH, eCheck, and closed-loop wallets to supplement card acceptance, especially in restricted categories.
Stop Playing the Miscoding Game
Visa and Mastercard have made it clear: the days of skating by with incorrect MCCs are over. If you’re in a high-risk industry, misclassifying your merchant account might seem like a shortcut, but it’s really a ticking time bomb.
