Introduction to Level II and Level III Processing

For business to business customers, Level II and Level III processing can provide lower interchange rates in exchange for providing more information during a transaction.

Level II processing includes additional customer and tax information for the transaction. Level III processing includes line-item data for each transaction. Barclays does not support Level II processing only. You must include at least one line-item to process Level II transactions with Barclays. See Supported Processors and Card Types: Level III for lists of the supported card types for your processor.

IMPORTANT

Barclays does not support discounting.

This document provides guidelines that indicate which fields are required to obtain the best interchange rates. These guidelines are based on industry information available at the time of publication. Cybersource recommends that you contact your acquirer for the most current information requirements, as these requirements can change at any time.
