Find Out if Your Nonprofit Already Has its 501c3

There are two ways to find out if your nonprofit already has its 501c3.

1.     Click here  and go near the bottom of the page where it says “Tax Exempt Organization Search.” Search by name or EIN, typing in the nonprofit name and/or the EIN (EIN is better because the IRS may have more than one nonprofit with your name). The IRS takes liberal opportunity to change its web site, so if this address isn’t correct, go to and select “Charities and Nonprofits” and then “Search for Charities.” If you don’t find your nonprofit’s name on the list, it does not necessarily mean that it does not have its 501c3, and you should go to step 2 below. (It is our experience that sometimes the IRS list is not comprehensive.)

2.     Call the IRS Customer Service for nonprofit organizations at 1-877-829-5500 and give them your corporate name (and EIN if you have it). The best time to call them is about 8:35 a.m. Eastern Time. Later in the day, they may be busy and unable to take your call.
