Level 2 and Level 3 data:
real interchange savings
for B2B merchants

Every commercial card — corporate cards, purchasing cards, small-business cards issued to a company rather than a person — carries a published interchange rate that is meaningfully lower than the standard rate for the exact same card, provided the merchant sends the network extra transaction detail at the time of authorization or settlement. Most B2B sellers process these cards through systems that were never built to send that detail, so every qualifying transaction defaults to a "Standard" or "Data Rate 1" tier that is, in effect, the wrong rate — not because anyone did anything improper, but because nobody configured the plumbing to claim the discount that already exists.

What "Level 2" and "Level 3" actually mean

The terms describe layers of transaction data, each one adding fields on top of the last. Level 1 is what every card transaction already sends — card number, expiration, transaction amount, merchant category code, date. It's the bare minimum any consumer swipe generates.

Level 2 adds business-purchase context: the sales tax amount charged on the transaction, a customer or purchase order reference number the buyer's accounting system can match against, and the merchant's tax ID. This is the data a company's card program needs to auto-reconcile a purchase against a PO without a human touching it.

Level 3 adds everything Level 2 has, plus true line-item detail: item description, quantity, unit of measure, unit cost, a product or commodity code, freight and duty amounts, and ship-from/ship-to postal codes. It's effectively an itemized invoice traveling with the transaction instead of a single lump total. Mastercard documents both tiers directly as "Level 2 and Level 3 data" in its Gateway developer documentation, calling the underlying interchange programs Data Rate 2 and Data Rate 3.

Who can actually qualify — and who can't

This is the detail that trips up the most merchants: enhanced-data interchange only exists for commercial cards. A corporate card, a purchasing card (P-card), or a small-business card issued to a registered company can qualify for Level 2 or Level 3 rates. A consumer credit card, a consumer debit card, or a personal rewards card issued to an individual cannot qualify — no amount of itemized data submitted on that transaction unlocks a lower rate, because the discounted tiers don't exist for that card category in the first place.

That makes the addressable savings a function of one thing: what share of your card volume is commercial. A pure consumer retailer has effectively nothing to gain here. A wholesaler, distributor, manufacturer, government contractor, or any B2B seller invoicing other companies — where a meaningful slice of buyers pay with a corporate or purchasing card — has real money sitting unclaimed on every one of those transactions that isn't sending qualifying data today.

The discount already exists in the network's rate table. Most B2B merchants simply never send the data that unlocks it.

Why most B2B sellers never claim it

Standard point-of-sale terminals and most off-the-shelf e-commerce checkouts are built to move Level 1 data only — card number, amount, date — because that's all a typical consumer transaction needs. Capturing and transmitting Level 2 and Level 3 fields requires a payment gateway, ERP integration, or invoicing platform specifically wired to pass line-item and tax data through to the processor at authorization or settlement. If your invoicing system doesn't carry structured item, quantity, and tax data — or your gateway can't forward it — the transaction settles at Level 1 by default, whatever discount existed on paper goes unclaimed, and nobody downstream flags it because nothing "failed." The transaction still authorizes and funds normally; it just clears at a costlier tier.

This is a close cousin of the downgrade problem covered elsewhere on this desk — a transaction that misses a data requirement doesn't get rejected, it gets quietly repriced. The difference here is that Level 2/3 data isn't a compliance requirement you accidentally miss; it's an optional upgrade path that has to be deliberately built and turned on.

What changed on the network side in 2026

Visa restructured how it incentivizes enhanced data during 2026 through what it now calls the Commercial Enhanced Data Program (CEDP), shifting more of the qualification weight toward complete Level 3 (line-item) data rather than Level 2 data alone. Practically, that means a merchant sending only Level 2 fields on Visa commercial transactions captures less of the available discount than one sending complete Level 3 detail — the gap between "some enhanced data" and "full enhanced data" widened rather than narrowed. Mastercard, by contrast, continues to run Level 2 and Level 3 as separate, distinct interchange programs (Data Rate 2 and Data Rate 3), each with its own qualifying rate. The practical takeaway is the same on both networks: line-item Level 3 detail captures meaningfully more savings than tax/PO-only Level 2 detail, and the gap matters more on Visa now than it used to. Program specifics move; confirm current requirements with your processor or gateway rather than relying on last year's guidance, and treat any specific percentage or dollar figure you're quoted as something to verify against your own statement rather than take at face value.

What the gap is worth

The exact discount varies by card product, network, and transaction channel — there's no single universal number, and any processor quoting one flat figure across every scenario should be treated skeptically. What's consistent across the published Visa and Mastercard commercial interchange tables is the shape of it: on a card-not-present commercial transaction, moving from bare Level 1 data up through Level 2 to complete Level 3 data commonly recovers on the order of a full percentage point of that transaction's value, concentrated mostly in the Level 2-to-Level 3 step rather than the Level 1-to-Level 2 step.

Run that against real volume and it stops being abstract. A B2B seller processing $50,000 a month in card-not-present commercial-card volume that clears entirely at Level 1 today, and could realistically qualify for Level 3 with the right gateway setup, is leaving somewhere in the range of a few hundred dollars a month unclaimed — not a rounding error at that volume, and it compounds every month the integration isn't built. At $500,000 a month in qualifying commercial volume, the same gap moves into five figures a year. None of this touches your consumer-card volume at all; it applies exclusively to the commercial-card slice of your business.

How to find out if this applies to you

Two questions decide whether this is worth pursuing. First: pull a recent statement and check what share of your card-not-present or invoiced volume is running on corporate, purchasing, or business cards rather than consumer cards — your processor can usually break this out by card product. If that share is small, the addressable savings are small regardless of what data you send. Second: ask your processor or gateway directly whether your current setup transmits Level 2 or Level 3 data today, and if not, what it would take to enable it — some gateways support it as a configuration change, others require an integration project with your invoicing or ERP system. There is no cost or downside to sending enhanced data on a transaction that doesn't qualify for a better rate; the network simply ignores fields a given card product can't use.

Frequently asked questions

What is the difference between Level 2 and Level 3 processing data?

Level 2 adds transaction-level detail on top of standard (Level 1) authorization data — tax amount, customer/PO reference number, and merchant tax ID. Level 3 adds line-item detail on top of Level 2 — item description, quantity, unit of measure, unit cost, product/commodity code, ship-from and ship-to postal codes, and freight/duty amounts.

Do Level 2 and Level 3 data work on any credit card?

No. Enhanced-data interchange tiers only apply to commercial cards — corporate, purchasing, and business cards issued to companies. A consumer rewards card, debit card, or personal credit card cannot qualify for Level 2 or Level 3 rates no matter what data a merchant submits.

How much can Level 2 or Level 3 data actually save a B2B merchant?

It depends entirely on commercial-card volume. On a card-not-present commercial transaction, moving from unqualified data to fully qualified Level 3 data commonly saves on the order of a full percentage point of that transaction's value. A merchant running $50,000 a month in card-not-present commercial-card volume can realistically be leaving several hundred dollars a month on the table by submitting bare Level 1 data.

Did Visa retire Level 2 processing?

Visa restructured its commercial enhanced-data incentive program in 2026 to weight qualification more heavily toward Level 3 (line-item) data rather than Level 2 alone, changing how much benefit a Level-2-only submission captures on Visa transactions specifically. Mastercard continues to operate separate Level 2 and Level 3 data-rate programs. Merchants should confirm current program rules with their processor rather than relying on older Level 2 guidance.

Does my point-of-sale or payment gateway automatically send Level 2/3 data?

Not by default in most systems. Standard retail POS and basic e-commerce checkouts are built to capture Level 1 data only. Capturing and transmitting Level 2 and Level 3 fields requires a gateway, ERP integration, or invoicing platform specifically built to pass that data through to the processor at the time of authorization or settlement.
