What is Level 3 data in payment processing?

Level 3 data is the most detailed tier of transaction information submitted to card networks, including line-item details like product descriptions, quantities, unit costs, commodity codes, tax, and freight. Merchants that submit accurate Level 3 data on qualifying commercial card transactions receive reduced interchange rates, typically saving 0.50% to 1.50% per transaction compared to standard processing.

Which card types qualify for Level 3 interchange rates?

Only commercial card types qualify for Level 3 interchange savings: corporate cards, purchasing cards (P-cards), government procurement cards, and fleet cards. Standard consumer credit cards and personal debit cards do not qualify regardless of how much transaction data the merchant submits. The card must be classified as a commercial instrument by the issuing bank.

What is the difference between Level 1, Level 2, and Level 3 data?

Level 1 is baseline transaction data every payment carries: card number, amount, and merchant name. Level 2 adds tax amount and customer reference codes. Level 3 adds full line-item detail including product descriptions, quantities, unit costs, commodity codes, freight, and duty. Each tier provides more transparency and qualifies for progressively lower interchange rates on commercial cards.

How does Visa's CEDP affect Level 3 data requirements?

Visa's Commercial Enhanced Data Program (CEDP) replaced the legacy Level 3 program in 2025 with stricter validation standards. Visa now uses AI to verify data quality and classifies merchants as verified or non-verified. Only verified merchants with complete, accurate data receive preferred Product 3 interchange rates. Placeholder values or math errors disqualify entire transactions.

How much can companies save with Level 3 processing?

Companies processing significant commercial card volume can reduce interchange costs by 0.50% to 1.50% per qualifying transaction. On $500,000 in monthly commercial card payments, that translates to roughly $2,500 to $7,500 in monthly savings. Navan's corporate card platform captures the granular transaction data needed to support Level 3 qualification on the merchant side.

Key Takeaways

Level 3 data is the most detailed tier of transaction information that merchants can submit to card networks, including line-item details like product descriptions, quantities, unit costs, and tax amounts. Submitting complete Level 3 data on qualifying commercial card transactions unlocks reduced interchange rates.

Merchants submitting Level 3 data can reduce interchange costs by 0.50% to 1.50% per qualifying transaction compared to standard Level 1 processing [1].
Only commercial card types qualify: corporate cards, purchasing cards, government procurement cards, and fleet cards. Consumer credit cards are not eligible for Level 3 interchange savings.
Visa replaced its legacy Level 2 and Level 3 programs with the Commercial Enhanced Data Program (CEDP) in 2025, requiring validated, invoice-quality line-item data to earn Product 3 interchange rates [2].
Navan captures 130-plus data elements per corporate card transaction automatically, giving finance teams the granular spend visibility that Level 3 data standards demand.
As of 2026, submitting weak or placeholder data on commercial card transactions incurs penalty fees in addition to forgoing the lower rate, making data quality a cost driver rather than just an optimization opportunity [3].

What is Level 3 Data?

Level 3 data is the most granular category of transaction information that merchants transmit to card networks (Visa, Mastercard) during payment processing. It includes line-item detail for every product or service in a transaction: item descriptions, commodity codes, quantities, unit costs, extended amounts, tax, freight, and duty. Card networks reward this transparency with lower interchange rates on qualifying corporate card transactions because the detailed data reduces fraud risk and simplifies dispute resolution.

The "level" terminology refers to a hierarchy of data richness. Level 1 is the baseline every transaction carries: card number, amount, merchant name, and merchant category code. Level 2 adds tax amounts, customer reference codes, and a few commercial-purpose fields. Level 3 adds the full invoice: every line item broken out individually with pricing, quantities, and descriptions.

How Does Level 3 Data Reduce Processing Costs?

Card networks set interchange rates based on perceived transaction risk. When a merchant submits only basic card-present data (Level 1), the issuing bank has limited information to assess the legitimacy of the charge. When that same merchant submits invoice-quality detail showing exactly what was purchased, the risk profile drops and the network applies a lower rate.

The savings are significant for B2B payment volumes. Merchants processing corporate card transactions can see interchange rates drop from approximately 2.65% to as low as 1.70% on qualifying transactions [1]. On $500,000 in monthly commercial card volume, that difference can represent $3,750 or more in monthly savings without changing pricing, products, or customer behavior.

These savings apply exclusively to commercial card types. A company paying suppliers with virtual cards or receiving payments on ghost cards assigned to cost centers benefits from Level 3 qualification only when those cards are commercial-grade instruments.

What Fields Does Level 3 Data Require?

Qualifying for Level 3 interchange rates requires submitting specific data fields for each line item in a transaction. Missing or inaccurate fields disqualify the entire transaction from preferred rates.

Required line-item fields include:

Item commodity code (category classification)
Item descriptor (specific product or service description)
Quantity and unit of measure
Unit cost per item
Extended line-item total
Discount amount (if applicable)
Freight or shipping charges
Duty amount (for cross-border transactions)
Tax amount and tax-exempt indicators
Customer reference or purchase order number

The sum of all line items, tax, shipping, and discounts must equal the total authorization amount. Arithmetic mismatches trigger automatic disqualification.

Visa's Commercial Enhanced Data Program (CEDP)

Visa overhauled its approach to enhanced data in 2025. The Commercial Enhanced Data Program (CEDP) consolidates the legacy Level 2 and Level 3 interchange structures into a unified Product 3 framework with stricter validation [2].

Under CEDP, Visa uses AI-driven validation to classify merchants as either "verified" or "non-verified" based on historical data quality. Verified merchants receive Product 3 interchange rates at daily settlement. Non-verified merchants may still receive benefits, but on a lagged basis (10-15 days after settlement) following Visa's data review.

Key CEDP timeline changes that affect corporate payment workflows:

April 2025: CEDP launched with a 0.05% per-transaction participation fee on all enhanced data submissions.
October 2025: Full enforcement began. Legacy Level 3 interchange categories sunset.
April 2026: Level 2 interchange incentives sunset entirely. Product 3 is now the only path to reduced Visa commercial rates.

Mastercard continues to maintain separate Level 2 and Level 3 qualification programs, though it introduced stricter units-of-measure requirements in October 2025.

Why Level 3 Data Matters for Corporate Expense Management

For companies issuing corporate cards to employees, Level 3 data flows through the entire expense reconciliation process. When merchants submit complete line-item data with each transaction, that detail appears on corporate card statements and feeds into expense platforms.

This creates two advantages beyond interchange savings. First, finance teams gain item-level spend visibility without requiring employees to manually itemize receipts. A hotel charge that includes room rate, parking, and minibar as separate line items makes automated expense categorization more accurate. Second, policy compliance checks become granular. An expense policy that caps meals at $75 per person can be enforced against individual line items rather than transaction totals.

Navan's expense platform uses this transaction-level detail to auto-categorize spend and route exceptions to the right approver, reducing the manual matching that typically delays month-end close.

The shift to CEDP also means that companies accepting commercial card payments from other businesses face a new cost calculus. Submitting accurate Level 3 data is no longer optional for cost control. Networks now penalize weak data submissions on top of withholding interchange discounts [3], making integration between ERP systems and payment gateways a finance priority.

Best Practices for Level 3 Data Compliance

Organizations on both sides of B2B transactions benefit from getting Level 3 right:

Automate data capture at the source. Pull line-item detail directly from invoicing or order management systems into the payment gateway. Manual entry introduces errors that trigger CEDP disqualification.
Avoid placeholder values. Generic descriptions like "services" or zero-value tax fields on taxable transactions fail Visa's validation checks and disqualify the entire transaction.
Audit monthly. Review transaction logs to identify which commercial card transactions qualified for Product 3 rates and which were downgraded. The gap between qualified and total volume represents recoverable savings.
Confirm processor readiness. Many legacy payment processors have not fully configured CEDP compliance. Verify that your gateway passes all required fields and that your merchant status is verified.
Reconcile weekly. When Level 3 detail flows into your credit card reconciliation workflow, the richer data makes matching faster but also surfaces more exceptions. Clearing them weekly prevents month-end backlogs.
