## Overview {#overview}

The Mastercard Merchant Identifier service provides detailed information about various data fields related to merchant information.
Please refer to the [Merchant Identifier Response Fields](https://developer.mastercard.com/merchant-identifier/documentation/tutorials-and-guides/data-elements/index.md#merchant-identifier-response-fields) table for a comprehensive understanding of the return fields.

## Merchant Identifier Response Fields {#merchant-identifier-response-fields}

This table lists all the fields available through the Merchant Identifier Service.
Before diving into the table, it's important to understand two key terms that appear frequently:

* Scrubbing is Mastercard's process of improving the readability of raw data. This step includes basic operations such as removing whitespace and eliminating extraneous characters.
* Cleansing is Mastercard's proprietary process of enhancing populated values for a data field. This extensive operation is performed by matching against third-party data sources, standardization, and leveraging rules and data science techniques to present the best possible field values.

Tip: For definitions of these and other terms used across the documentation, see the [Glossary](https://developer.mastercard.com/merchant-identifier/documentation/glossary/index.md).
