Level 2 Data

Also called Level II, L2 data, enhanced data

Extra fields - PO number, sales tax, tax ID - passed with a commercial card transaction to earn cheaper interchange. Visa retired it in April 2026; Mastercard and American Express still run it.

What it is

Level 2 is the first tier of enhanced data. When a business, corporate, purchasing or government card is used, passing additional fields with the authorization qualifies the transaction for a cheaper interchange category. Whether that still works depends entirely on the network, and this is where most advice written before 2026 is now wrong. Visa retired its Level 2 program on 18 April 2026 and folded enhanced data into the Commercial Enhanced Data Program. The only Level II category Visa still lists is a fuel-specific one. Mastercard continues to run both Level 2 and Level 3. American Express supports Level 2 with advance approval and has no Level 3 equivalent. Discover has neither. The required Level 2 fields are a customer or PO code, the sales tax amount, the merchant postal code, a sales tax indicator, and optionally the merchant tax ID. One rule catches people: the sales tax amount must be between 0.1% and 31% of the transaction total. A transaction with zero tax - common on wholesale or resale sales - will not qualify on that basis, which is a real limitation for some distributors and one nobody mentions at signing. Where it still applies, Level 2 is achievable on many terminals and virtually all gateways, which made it the easy half of the enhanced-data opportunity. On Visa volume that easy half no longer exists: the equivalent saving now requires the full line-item data set, and the data has to survive an accuracy check. We do not reprint interchange rates. They change every April and October, and a figure copied into a reference page is wrong within months - see the source below for the current schedule.

Why it matters to your business

If you take business or purchasing cards - contractors, wholesalers, professional services, medical and dental suppliers, marine parts, anyone selling to other businesses - enhanced data is still likely the largest single fixable line on your statement. What changed in April 2026 is which network pays you for it. The practical consequence is that a merchant who enabled Level 2 years ago and never revisited it has been losing the Visa portion of that saving since April, and it does not appear as a line item. It shows up only as a slightly worse effective rate. Mastercard and Amex volume is unaffected. Anyone still selling "turn on Level 2" as a Visa saving in 2026 is quoting a program that no longer exists.

Where it gets contested

The problem with Level 2 is not that it's controversial. It's that it's almost never enabled, and the reason is that nobody's compensation depends on it. Enabling Level 2 requires someone to configure fields, map data from the merchant's invoicing system, and run test transactions. It takes hours, not weeks. It saves the merchant real money on commercial card volume. And on tiered pricing, it saves the merchant nothing at all, because the qualification improvement lands inside a bucket the processor prices - which is a structural reason a tiered-pricing processor has no incentive to mention it exists. The second issue is silent failure. A merchant told their account is Level 2 enabled may still be downgrading, because the fields are technically enabled but not actually populated - the POS passes a blank PO field and a zero tax amount and the transaction qualifies for nothing. Enabled is not the same as passing. Only the interchange qualification report shows which. What processors don't say out loud: B2B merchants on non-optimized commercial card interchange are overpaying by a wide margin, and identifying that is a thirty-minute statement review that most reps have never been trained to do.

How to check it yourself

Get an interchange qualification report and split it by network before you conclude anything. On Mastercard, look for Data Rate II designations on commercial, corporate, business, purchasing, GSA or fleet transactions. If they are not there, you are not capturing it. On Visa, Level 2 categories are gone - look instead for Commercial Product 3 or Business Product 3. Volume landing in the standard commercial card-not-present category, or in non-qualified, is enhanced data that did not qualify. Then verify the fields actually populate. Run a test transaction and ask your processor to confirm the PO and tax fields arrived non-empty, because a gateway will cheerfully send blanks and report success.
