What Is Level 2 and Level 3 Processing?
Every card transaction carries data from the merchant to the card networks and issuing banks, and the depth of that data determines how the transaction is classified for interchange. Standard consumer purchases send Level 1 data: the basics like card number, amount, and merchant category. Commercial cards can send far more.
Level 2 data adds a sales tax amount (or a tax-exempt indicator) and a customer or purchase-order reference. Level 3 datagoes further still, adding full line-item detail for every product or service in the transaction — descriptions, quantities, unit costs, unit-of-measure codes, freight, and discounts. The more complete and accurate this data, the more favorably the networks can classify eligible business, corporate, and purchasing card transactions.
One thing to understand up front, because it changed recently: “Level 2” and “Level 3” still describe this enhanced data, and that data is still what unlocks better commercial rates. But the programs the networks use to price it have diverged. On Visa, enhanced commercial data is now handled through the Commercial Enhanced Data Program (CEDP). On Mastercard, it continues to flow through the established Data Rate II and Data Rate III programs. The sections below cover each network on its own terms.
How Enhanced Data Lowers Your Commercial Interchange
Interchange is typically the largest single component of card-processing costs, and the networks set it based on many factors — including card type, merchant category, and the level of data submitted. When a business card that could qualify for a lower commercial rate is processed with only basic data, it settles at a higher, non-enhanced rate.
Submitting complete Level 2 and Level 3 enhanced data lets eligible commercial transactions qualify for lower interchange categories, because the added detail helps issuers reconcile corporate spend, reduces disputes, and creates a clearer audit trail. The size of the benefit depends on the card types involved and the quality of the data — which is why we analyze your actual card mix rather than promising a blanket percentage.
Visa's Commercial Enhanced Data Program (CEDP)
Across 2025 and 2026, Visa replaced its separate Level 2, Level 3, and large-ticket commercial incentive programs with a single framework: the Commercial Enhanced Data Program. If your business accepts Visa commercial cards, several things changed in ways worth understanding:
- Level 3 became Product 3.The enhanced commercial rate tier that used to be called Level 3 is now Visa's Product 3 classification.
- Visa's standalone Level 2 rate tier was retired in 2026. On Visa, there is no longer a separate Level 2 interchange program to qualify for — the meaningful commercial savings now sit at the full-data Product 3 level.
- Data accuracy is now enforced automatically. Visa validates submitted data and rejects placeholder, static, or inconsistent values that would have passed in the past. Totals must reconcile, and tax-exempt transactions must be flagged as such rather than sent as zero tax.
- Qualification is ongoing, not one-time. Rather than enrolling once, merchants are evaluated continuously on the quality of the data they send, and Visa can reclassify transactions after the fact if the data does not hold up.
- A new program participation cost applies. Visa now adds a small per-transaction participation fee to commercial transactions that carry enhanced data, which should be weighed against the interchange savings.
One important nuance: following Visa's 2026 rate changes, the savings picture now varies sharply by card type. Visa corporate and purchasing cards continue to see meaningful reductions when full enhanced data is submitted. Visa small-business cards see much smaller reductions, and in some cases submitting partial (Level 2 only) data on those cards no longer produces a benefit at all. Ireland Pay helps you send full, qualifying data where it counts and avoid paying for data that will not.
Mastercard: Data Rate II and Data Rate III
Visa's CEDP overhaul does not apply to Mastercard. Mastercard continues to run its long-standing commercial enhanced-data programs — Data Rate II (comparable to Level 2) and Data Rate III(comparable to full Level 3 line-item data) — with less rigid validation than Visa's new system. Mastercard has tightened some data-formatting requirements, but it did not restructure these programs the way Visa did.
The practical takeaway is that the two networks now need to be handled separately. A combined “Visa and Mastercard Level 2” program no longer exists, and the requirements, rates, and qualification rules differ between them.
Who Qualifies for Lower Commercial Rates?
The reduced rates apply specifically to transactions made with business-class cards — corporate cards, purchasing cards (P-cards), and business credit cards. They do not apply to standard consumer credit or debit cards, regardless of what data is submitted. Because the issuer determines the card type, you cannot control which customers pay with an eligible card — but if your customers are primarily other businesses or institutions, a meaningful share of your card volume is likely eligible.
The businesses that benefit most typically include:
- Wholesale distributors selling products to retailers, restaurants, or other businesses
- Manufacturers supplying components or finished goods to commercial buyers
- Professional services firms including law firms, accounting practices, IT consultancies, and marketing agencies
- Government and institutional suppliers that accept commercial or purchasing cards
- Office supply and industrial suppliers serving business accounts
- Medical and dental supply companies selling to healthcare practices
If that describes your business, Ireland Pay's merchant services teamcan review your statement and card mix to estimate what you stand to save — and confirm the current rates with your processor before anything is promised.
What Data Is Required
Requirements differ by network, but the direction is the same: more complete, accurate data qualifies for better rates.
Visa (CEDP / Product 3)
To reach Visa's enhanced Product 3 rates, transactions generally need full line-item data — item descriptions, quantities, unit costs, unit-of-measure codes, tax, freight, and discounts — along with reference details such as customer or purchase-order numbers. The data must be real and accurate rather than auto-filled or generic: line-item totals must reconcile with the transaction amount, and tax-exempt sales must be flagged as exempt rather than sent as zero tax. Data must accompany the transaction or be supplied within Visa's enhanced-data window (currently 96 hours). Simply passing data fields does not guarantee the Product 3 rate — Visa validates the content.
Mastercard (Data Rate II / III)
Mastercard's Data Rate II generally requires a sales tax amount (or tax-exempt indicator) and a customer reference, while Data Rate III requires full line-item detail similar to Visa's. Mastercard's validation is currently less strict than Visa's, though it has tightened certain formatting rules such as unit-of-measure codes.
A quick clarification worth making: address verification — matching the cardholder's billing ZIP code, or AVS — is a separate fraud control from the commercial enhanced-data fields above. Both are worth enabling, but AVS is not part of the Level 2 data that earns commercial rates.
Savings Depend on Your Card Mix — and We Won't Guess
Because Visa's authoritative rate tables are not publicly published and every figure in circulation is processor-specific, we deliberately avoid quoting blanket savings percentages or fixed dollar amounts on this page. What we can tell you is directional and honest:
- The clearest savings are on Visa corporate and purchasing cards and Mastercard commercial cards processed with full enhanced data.
- Savings on Visa small-business cardsare considerably smaller after Visa's 2026 changes, and partial data on those cards may no longer help.
- Any savings should be weighed against Visa's new participation cost and the effort of sending accurate data on every transaction.
The right answer is specific to your business. Send us a recent processing statement and we'll analyze your actual card mix, confirm the current rates with your processor, and show you a realistic estimate — with no guarantees we cannot stand behind.
Ongoing Data Quality, Not a One-Time Setup
Under the old model, enhanced data was largely set up once and left alone. Under Visa's CEDP, qualification is scored continuously: transactions must carry accurate data every time, status is reassessed on an ongoing basis, and Visa can reclassify a transaction and reclaim a discount after settlement if the data does not pass validation. In practice, a merchant can qualify one month and slip the next over small data errors.
That makes enhanced-data processing an ongoing discipline rather than a one-time switch — and it is where Ireland Pay adds the most value. Our point-of-sale and gateway integrations are configured to capture and transmit the required fields automatically, and we help keep your data clean so eligible transactions keep qualifying. Implementation is typically measured in days, not weeks, with no change to how your customers experience checkout.
Combining Enhanced Data with Fraud Prevention
The same detailed data that supports better commercial rates also strengthens fraud prevention. Customer references, tax detail, and line-item records create a clearer audit trail that makes suspicious activity easier to spot and disputes easier to defend. Ireland Pay pairs enhanced-data processing with our full suite of fraud and dispute tools, so your business benefits from both cleaner economics and stronger security.
