Washington, D.C. runs roughly 125 licensed cannabis retailers under a medical framework that lets adults self-certify, producing about $140 million in 2025 sales. Bank-to-bank ACH settles the full basket next day on federally regulated banking rails, with no card network in the transaction.
D.C. has adult-use demand running through a medical license structure, which is unusual and shapes everything downstream.
The short version
- About 125 licensed retailers serve the District under a medical self-certification model.
- A congressional appropriations rider has blocked a conventional commercial adult-use market.
- The licensed market competes directly with unlicensed gifting operations.
- Bank-to-bank ACH runs on federally regulated banking rails with next-day settlement.
The District market, in numbers
The District recorded roughly $140 million in licensed cannabis sales in 2025, up about 22%, across about 125 licensed retailers regulated by the Alcoholic Beverage and Cannabis Administration. Roughly 37,000 people are registered under the program.
The structure is unusual. Possession has been legal in D.C. since 2015, but a long-running congressional appropriations rider has prevented the District from standing up a taxed commercial adult-use market. Instead, D.C. widened its medical program so adults 21 and over can self-certify, which converted much of the demand into licensed channels.
The licensed market still competes with unlicensed gifting operations, which carry none of the compliance cost. Licensed retailers therefore compete on legitimacy and reliability, and a payments outage undercuts exactly the thing they compete on.
Why card processing closes in Washington, D.C. too
The mechanism is national, not local. Card networks require every merchant to be classified with a four-digit merchant category code when an acquiring bank boards the account, and there is no code for state-licensed cannabis. A licensed D.C. retailer accepting cards is boarded under a category that does not describe it, and network monitoring is built to find exactly that mismatch.
Washington, D.C.’s own rules do not change this. State licensing determines whether you can operate; card network operating rules are written against federal law, which has not moved. The sequence is the same everywhere: the account boards, it works for a while, monitoring flags the mismatch, and the account terminates with settled funds held, commonly for around 90 days.
Cashless ATM and PIN debit programs are common among D.C. retailers and carry the same underlying structure regardless of how the terminal is labeled at the counter.
Bank-to-bank ACH as the alternative
ACH moves money directly between the customer’s bank account and the merchant’s, on federally regulated banking rails. There is no card network in the transaction, so no merchant category code applies and there is no network monitoring comparing behavior against a coded category.
At the counter the customer scans a QR code with their phone camera, connects their bank once in about thirty seconds, and confirms. No app download. Every purchase after that is a single confirmation, typically under twenty seconds. Greencard Payments platform data puts the repeat rate at roughly 87%. Funds settle next day into your own account, and cash acceptance is unaffected — this is an addition to the payment mix, not a replacement.
Federal proximity, federal rules
Operators in the District run their businesses inside the jurisdiction whose federal law is the reason for the merchant category code gap in the first place. Nothing about that proximity changes the underlying classification problem, and it does not make card acceptance any more durable here than in Denver.
What it does change is scrutiny. A D.C. operator has less room than most for an acceptance arrangement that depends on a card transaction being described as something it is not.
Bank-to-bank ACH does not route through the card networks at all, so no merchant category code applies to the transaction. That is a structural difference in how the money moves, not a better-worded application.
Delivery, online and wholesale
The District is compact and delivery is a meaningful channel for licensed retailers. SMS pay links settle a delivery order before the courier leaves, and e-commerce prepay collects the full basket on online pickup orders.
On the supply side, wholesale between licensees still settles largely in cash and checks. B2B invoicing on the same platform settles against a specific invoice, next day, with recurring billing for standing orders, and every transaction posts to QuickBooks automatically.
