What Are Level 2 and Level 3 Data?

Card transactions carry different amounts of data. Level 1 is the basic set sent with every payment. For purchasing, corporate, and fleet cards, the card networks allow richer data with each payment. Level 2 adds fields such as the tax amount, a customer or purchase order reference, and the merchant’s postal code. Level 3 adds line-item detail: product codes, descriptions, quantities, units of measure, unit prices, discounts, and freight. Sending the extra data can qualify the transaction for a lower interchange category than the same card would otherwise receive.

The benefit is narrow, and that is what makes it a sales conversation. It applies to businesses that sell to other businesses or to government and accept commercial cards, such as distributors, suppliers, and contractors with large invoices. The merchant’s software or gateway must be able to pass the fields, and the pricing model must let the savings reach the merchant: under blended or flat pricing the processor may keep the difference, while interchange-plus structures pass interchange changes through. A rep who asks how much of a merchant’s volume is commercial cards is asking the right question.

People confuse these with PCI levels, which rank a merchant’s security compliance obligations by transaction volume and have nothing to do with data fields. Expecting savings on consumer cards is another error, since they do not qualify. Inaccurate line items can cause downgrades, and the processor will not configure the gateway automatically. Setup usually takes work on the merchant’s invoicing or ERP side.
