If you’re a B2B merchant that used to get reduced interchange rates on commercial card transactions but no longer do, getting this resolved should be a top priority.
Interchange optimization is one of the best ways to save money on payment processing because you’re starting at the source. And when those savings go away, high-volume merchants can easily see their processing fees increase by five figures in a single month.
But you probably never got a clear explanation of why you no longer qualify for reduced Level 2 or Level 3 interchange rates.
There isn’t a single answer.
The reasons why merchants lose L2/L3 savings can be very different, and so are the responses for getting it fixed. So before you do anything else, you need to figure out which scenario you fall into.
Program Changes at the Network Level
Visa replaced its legacy Level 2 and Level 3 interchange programs with a new Commercial Enhanced Data Program (CEDP) back in April 2025.
This was not just a rebrand of the old program. CEDP was a complete structural overhaul with stricter validation requirements and even new rate categories.
Merchants who previously qualified under the old system didn’t automatically carry over. And since CEDP rolled out in phases, many merchants are just now realizing that those savings have disappeared even though the program was officially introduced more than a year ago.
To qualify for CEDP rates, you need to become a “verified” merchant by complying with Visa’s new data quality standards. And if that never happened, your commercial transactions likely defaulted to the standard interchange rates without any obvious notice.
Your Processor Was Never Submitting Clean Data to Begin With
One of the reasons why Visa introduced CEDP was to combat “automatic” interchange optimization. For years, processors offered Level 2 and Level 3 optimization services that genuinely resulted in lower interchange rates for merchants.
The problem was that these processors weren’t actually collecting Level 2 and Level 3 data. Tons of processors were just using placeholder data and generic descriptions that looked complete and passed validation.
Visa’s system now checks the math and reconciles across line items and requires that every description contains real values.
If your rates changed around October 2025 and never recovered, there’s a good chance that this is the reason why.

Level 2 Rates No Longer Exist
This one is straightforward but worth stating regardless: Visa eliminated Level 2 interchange for Small Business and Commercial cards in April 2026.
So if you were previously qualifying for reduced rates by submitting Level 2 data, that discount is gone. Level 2 data alone no longer qualifies you for anything under CEDP.
The only path forward to reduced interchange on commercial Visa cards now runs through Level 3, meaning you’ll need to capture significantly more data than you were previously.
Make sure your systems are set up to capture and pass along everything based on the new requirements.
Data Quality Slipped and Nobody Told You
Sometimes an internal action on the merchant’s side is what triggered the problem.
What used to be a set-it-and-forget-it qualification process is now something that requires monthly maintenance. Transactions can pass validation one month and then fail the next depending on your data quality.
Things like an ERP upgrade, new software integration update, integrated payment change, or a gateway configuration change on the processor side can quietly break the data fields that were being submitted on commercial transactions.
A single missing field or misformatted data point is enough to downgrade the transaction to standard interchange.
The worst part about this is that processors have no financial incentive to flag this for you. Their markup sits on top of the interchange regardless of whether your transactions are qualifying for the lowest possible rate or the highest possible rate. So if your data breaks, they aren’t losing anything.
This is worth emphasizing because lots of merchants assume their processor is monitoring CEDP qualification on their behalf. But most aren’t (at least not proactively), even if they’re charging you extra for an enhanced data service.
Visa Paused New Verifications
Visa stopped approving merchants as “verified” back in November 2025.
So if you missed the original window for getting compliant or if you’re newly eligible and haven’t gone through the verification process yet, you’ll need to wait until Visa resumes approvals.
That said, you can still qualify for reduced interchange rates under CEDP even if you aren’t verified.
Clean data submission still qualifies you for CEDP credits through the lagged interchange process in the meantime.
You Switched Processors
Your CEDP qualification status is tied to your processor.
So a merchant that switched providers after getting verified will lose their verification status until they go through this process again with their new provider.
But as mentioned above, new verifications are still paused. So you’ll need to focus on getting reduced rates in the form of a credit (10-15 days after settlement) as opposed to getting them automatically at the time of the transaction.
You can’t get re-verified until Visa lifts the pause.
The Rate Math Changed
For some merchants, the issue isn’t that you were suddenly disqualified from a particular program. It’s that qualification is no longer worth what it used to be.
January 2026 rate changes increased Product 3 rates across Small Business tiers by 65 basis points.
So for certain card types, the savings from submitting Level 3 data barely offset the 0.05% participation fee and whatever expenses you’re incurring from capturing and submitting enhanced data.
The net benefit here is minimal.
So if your savings shrunk significantly in 2026 rather than disappearing entirely, this is likely part of the picture. It doesn’t mean you should stop participating entirely, but it does mean you should revisit your costs against your actual commercial card volume to see if the extra effort is still worth it.
Your MCC Excludes You From the Program
Certain business types and industries are excluded from CEDP entirely, regardless of how accurate your data is.
Travel (airlines, hotels, card rentals, cruise lines, travel agencies), restaurants (MCC 5812 and 5814), and fleet single-fuel-only transactions don’t qualify for Product 3 rates.
This matters because the 0.05% CEDP participation fee still applies to eligible transactions even if your MCC excludes you from the rate benefits. So if you’re in a non-eligible category but your processor still has you enrolled in CEDP, you could be paying a fee for something that offers zero savings.
In this case, the fix is to opt out of participation entirely rather than wasting time trying to submit better data.
What to Do About It
Each of these scenarios above has a different fix.
A merchant using a processor that was never submitting clean data needs a completely different solution than one who used to qualify for Level 2 rates or a business that switched processors after being verified.
But one thing most of these situations have in common is that your processor likely isn’t going to remedy everything on their own.
Whether it’s a data quality issue, missed transition to CEDP, or a fee you’re paying with no benefit, the only way to actually know what’s happening is to look at all of your numbers independently.
