Tax Exempt Organization Search provides access to IRS information about tax-exempt organizations. The information is produced from computer records and is subject to certain limitations, particularly in the format and arrangement of the entries. Searching - in general To pinpoint an organization, include the name, or part of the name, in quotation marks. For example, to search for Anytown General Hospital, enter "Anytown General Hospital" or "Anytown General". Fields are not case-sensitive. When entering an employer identification number, the dash after the first two digits is optional. Organizations are listed under the legal name or a “doing business as” name (dba) that is on file with the IRS. No separate listings of common or popular names of organizations are included. Some exceptions to the general rule may appear, however. In the Pub 78 data (organizations eligible to receive tax-deductible charitable contributions), dba names of organizations are not listed. Effective searching tips Avoid common words such as the or Foundation. If your search is not producing good results, search using more terms or fields and then sort your results to pinpoint the result you need. For example, you can focus your search results by sorting by city, state or zip. When searching for organizations on the Auto-Revocation List, you can narrow your search to organizations whose names were added to the list during a particular time frame. You can enter the date information in the required MM-DD-YYYY format or by selecting the date range on a calendar. Note: Date range searches are not inclusive. If you want to search for organizations whose revocation was posted on the 12th or 13th of a month, enter a search range of MM/11/YYYY to MM/14/YYYY. If an organization is listed on the Auto-Revocation List, you can search organizations eligible to receive tax-deductible contributions (Pub. 78 data) to see if its tax exemption has been reinstated. Due to the different structure of foreign addresses, data is sometimes found in an unexpected location. For example, the province or country in which the organization is located is sometimes in the City field in the Auto-Revocation database. Thus, if you are not obtaining expected results, try searching for information in a different way.
