How to find a charity's EIN, and where your return actually asks for it

It is filing season, the software is asking for the charity's tax ID number, and you are holding a receipt with a store name on it and nothing that looks like a number. This is the most common dead end in the whole donation workflow, and it has a slightly surprising resolution: on the federal form itself, you usually do not need the number at all.

Both halves of that are worth having. Here is how to find an EIN when you want one, and where the requirement actually lives.

What an EIN is, in one line

The IRS describes an employer identification number as “a federal tax ID number for businesses, tax-exempt organizations and other entities.” It is nine digits, written 12-3456789, and it is the only thing that identifies one organization uniquely. Names do not: dozens of legitimate charities share a name, and one charitable brand can cover hundreds of separately incorporated organizations.

It is worth clearing up what an EIN is not. It is not proof of exempt status. Publication 1828 states the point directly: “The IRS does not assign a special number or other identification as evidence of an organization's tax-exempt status.” There is no exemption number. An EIN identifies; it does not certify.

Four ways to find one

1. The receipt

Start here, because it is both the fastest route and the most accurate one. A donation receipt or acknowledgment letter usually carries the organization's legal name and often its EIN, and crucially it names the entity that actually received your donation, which a web search cannot do for you.

If you dropped bags at an unattended bin and have nothing at all, read the drop-box section of our receipts article before worrying about the EIN: the record you are missing is a bigger problem than the number.

2. IRS Tax Exempt Organization Search

The IRS runs a free lookup, usually called TEOS. No account, no fee. Search by organization name, narrowed by city and state, and the result gives you the EIN alongside what the IRS knows about the organization's status.

The dataset you want to land in is the Publication 78 data, which the IRS describes as the “list of organizations eligible to receive tax-deductible charitable contributions.” A hit there is the answer to both questions at once: this is the number, and yes, gifts to it are generally deductible. The tool also searches the automatic revocation list, determination letters issued from 2014 onward, Form 990-N filings, and the full Form 990 series returns.

3. The organization's Form 990

Annual returns in the Form 990 series are public, searchable through the same IRS tool, and the EIN is on the front page of the form. This route is useful when a name search returns several candidates and you want to tell them apart by what they actually do and where they operate.

4. Ask the organization

Underrated. A charity's EIN is public information that it puts on every acknowledgment letter it sends, and any treasurer or development office can read it to you in ten seconds. This is the only reliable route for a small congregation or a local group that never appears in the search tool, which is a normal situation rather than a red flag: the IRS states that churches, group ruling subordinates, and governmental units eligible to receive tax-deductible contributions may not be listed in the Publication 78 data.

Where the return actually asks for it

Here is the part almost nobody gets told. On Form 8283 (Rev. December 2025), the form for noncash charitable contributions, Section A Part I column (a) asks for the “Name and address of the donee organization.” That is it. There is no identifying-number field anywhere in Section A, and Section A is the half that covers deductions of $5,000 or less, which is nearly every household clean-out ever made.

The only “Employer identification number” box on the whole form sits in Section B, Part V, the Donee Acknowledgment. Section B applies to an item or group of similar items deducted at more than $5,000, and Part V is completed and signed by the charity, not by you. In that part the organization acknowledges that it is a qualified organization under section 170(c) and that it received the property described, and it prints its own name, address, and EIN.

Why it is still worth writing down

None of the above makes the EIN useless. It makes it a record-keeping tool rather than a filing requirement, which is a better reason to capture it.

• It disambiguates. Three years later, “the thrift store on Route 9” is not an organization; a nine-digit number is.
• It is the fast path back to the IRS lookup, which is the only way to check whether an organization's status has changed since you gave.
• A preparer reconciling a client's noncash schedule can group by EIN in seconds and by store name never.
• If a donation ever does cross $5,000 for a group of similar items, the charity's details are already in hand when Section B lands on the table.

The right moment to capture it is the moment you are handed the receipt, not the following April. That is the argument for recording a donation the day it happens rather than reconstructing a year of them from a shoebox, which is what DeductiBee is for: the organization, the date, the photos, and a cited value range live on one record and export together.

While you are in there, check the status

You are already in the lookup, so spend the extra ten seconds. A hit in the Publication 78 data tells you the organization is eligible to receive tax-deductible contributions. A hit on the automatic revocation list tells you something more urgent: the IRS states that organizations which do not file for three consecutive years automatically lose their tax-exempt status.

If a revocation shows up, check the dates before assuming the worst. The IRS states that donors can deduct contributions made before an organization's name appears on the Automatic Revocation List. Your dated receipt is what settles which side of that line you were on. The full picture, including the three categories of qualified organization that never show up in the search, is in our guide to whether an organization qualifies.
