About the Database and Locator Service The "Authorized IRS e-file Provider" database is a nationwide listing of all businesses which have been accepted to participate in the electronic filing (IRS e-file) program. "For Profit" Providers that have "opted in" are included in the locator service which allows you to: Identify and locate different types of Authorized IRS e-file Providers through interactive searches - e.g., Electronic Return Originators (EROs), Transmitters, Software Developers, and Intermediate Service Providers. Download delimited text files by state or District of Columbia for creating mailing lists using data base software packages. See "Downloading Delimited Text Files" below. To opt in or out of the locator service, see "Updating the Authorized IRS e-file Application" below. How to Search for a Provider This interactive search allows you to enter the either your full 5 digit ZIP Code, or select your state. Search results will be sorted in alphabetical order by the business name. Use the arrow at the bottom right of the page to advance to the next page.

The delimited text files contain "records" grouped by state or the District of Columbia. These text files can be imported into database software packages and used to create mailing lists. Updating the Authorized IRS e-file Application The IRS e-file Application is available through the Internet-based business tools called e-Services.

This is done by selecting "yes" or "no" on the Firm Information page of the application.
