How do you search for an EIN by company name?
You search for an EIN by company name through 6 routes: SEC EDGAR, EDGAR full-text search, the IRS Tax Exempt Organization Search, a filed Form 990, a signed Form W-9, and your own CP-575. Each costs $0.
The routes are ordered by how fast a name resolves without asking anyone for anything. Routes 1 to 4 read records that are already published. Route 5 asks the company. Route 6 applies when the company is yours, and it is the shortest of the 6 at 1 step.
Route 1: Search the company name in SEC EDGAR
Three steps: type the legal name into EDGAR, open any 10-K, 10-Q, or 8-K, and read the filing header, which prints the EIN under the label IRS number.
Covers no company that has never filed with the SEC.
Route 2: Run the name through EDGAR full-text search
Four steps: enter the name, open a matching filing, locate the entity inside the document, and read the EIN. Full-text search reads the body of filings from 2001 forward, so a subsidiary named inside a parent exhibit surfaces even when it holds no filer record of its own.
Reads filings from 2001 forward and nothing filed before that.
Route 3: Search the IRS Tax Exempt Organization Search
Two steps: enter the legal name, then read the 9-digit EIN the IRS prints beside it. The tool accepts a partial name and a state filter, and it covers every registered tax-exempt organization.
Covers no for-profit company of any size.
Route 4: Read the nonprofit's own Form 990
Three steps: find the filed return, open page 1, and read item D of the heading block. Form 990, Form 990-EZ, and Form 990-PF all print the EIN there. Large charities post the return on their own site.
A return names the filing entity, not the brand printed on the appeal letter.
Route 5: Request a signed Form W-9 from the company
Three steps: send the request, receive the signed form, and read line 6, which carries the EIN under a signature attesting that it is correct. Vendors, clients, and payment processors request one as routine paperwork.
The company chooses whether to answer, because no law compels a reply to a stranger.
Route 6: Read your own records when the company is yours
One step: read the CP-575 assignment letter, which prints the EIN beside the legal name it was issued to. A 147C letter reissues the same pairing when the CP-575 is gone.
The IRS releases a 147C to an authorized person only.

How do you find a public company’s EIN by name?
Type the legal name into SEC EDGAR, open the newest 10-K or 10-Q, and read the filing header. The EIN prints there under the label IRS number. The search takes 3 steps and costs $0.
EDGAR works as a name search because federal securities law requires the filings and the SEC indexes each registrant by its legal name. The header block of every 10-K, 10-Q, and 8-K carries the state of incorporation, the commission file number, and the 9-digit EIN in the same 3 lines.
Two EDGAR searches exist and they answer different questions. The company search matches a registrant name and returns that filer’s history. Full-text search reads the body of filings from 2001 forward, which is the route that finds a subsidiary named inside a parent’s exhibit list rather than as a filer of its own.
A worked example
A researcher searches a well known consumer brand and EDGAR returns 0 results. The brand is a product line, not a registrant. Searching the parent holding company returns the filer, and the 10-K header carries 1 EIN for that parent. The brand itself carries none, because a brand is not an entity and the IRS assigns an EIN to entities.
The same logic explains why a large group produces several EINs. A parent, each incorporated subsidiary, and each separately chartered bank hold their own numbers. Exhibit 21 of a 10-K lists the subsidiaries by name, which turns 1 search into a map of the group.

How do you find a nonprofit’s EIN by name?
Search the name in the IRS Tax Exempt Organization Search. It returns the 9-digit EIN beside the registered legal name in 2 steps at $0. Item D on page 1 of Form 990 prints the same number.
This is the only name-based EIN search the IRS itself operates. It exists because tax-exempt status is a public privilege: an organization that accepts deductible donations files an annual return the IRS then publishes. Form 990, Form 990-EZ, and Form 990-PF all carry the EIN in item D of the heading block.
Search the entity, not the campaign. A national charity and its state chapter hold 2 separate EINs under 2 separate legal names, and the receipt a donor needs carries the EIN of whichever entity took the money. The Tax Exempt Organization Search lists each registration under its own name and accepts a state filter to separate them.
A nonprofit name that returns nothing has 3 common explanations: the organization is a chapter operating under a parent’s group exemption, the registration lapsed after 3 consecutive years of unfiled returns, or the organization is not tax-exempt at all.
How do you find a private company’s EIN by name?
Ask the company for a signed Form W-9. Line 6 carries the EIN and the signature attests it is correct. No public database lists private company EINs, so the request is the only reliable route.
A W-9 request is ordinary business paperwork rather than an unusual ask. A payer who will issue a Form 1099 needs the number, and a company that expects payment returns the form the same day. That is why the route works: the incentive runs in your favour when money is moving.
The number matters because of what happens when it is wrong. An incorrect or missing TIN on a payee record puts the payer on the hook for 24% backup withholding, so collecting a signed W-9 before the first payment is cheaper than correcting the record afterwards.

Once you hold a number, confirm the pairing rather than the digits alone. Work through the confirmation steps on the verify ein number page.
Why does the legal name decide whether an EIN search works?
The IRS keys an EIN to the legal entity name, and it matches against a name control built from the first 4 characters of that name. A brand, a DBA, or a punctuation variant fails the match.
Almost every failed name search is a name problem rather than a database problem. The name on a website, an invoice, or a storefront is a trade name. The name in IRS and SEC records is the one on the formation document filed with the state, and the two differ far more than people expect.
| Name you are holding | What it actually is | Carries an EIN | What to search instead |
|---|---|---|---|
| Brand or product line | Marketing name, no legal status | No | The entity that owns the brand |
| DBA or trade name | A registered alias of one entity | No | The legal entity behind the DBA |
| Storefront or franchise name | A license held by a local entity | No | The local franchisee entity |
| Subsidiary name | A separate incorporated entity | Yes | The subsidiary itself, in EDGAR full text |
| Former legal name | The name before an amendment | Yes, the same EIN | The current name, then Form 8822-B history |
| Legal entity name | The name on the formation document | Yes | Nothing, this is the correct input |

The 4-character rule produces results that look arbitrary until you see the mechanism. The name control for a corporation comes from the first 4 characters of the corporate name, ignoring the word The when more than one word follows. A search that writes L.L.C. where the record says LLC breaks the string the IRS is matching on. Read how that string is built on the IRS name control page.
A name change never changes the number. The entity keeps its EIN and records the new name with the IRS on Form 8822-B, which is why a search on the current name and a search on the old name lead to 1 EIN, not 2.
Which databases let you search an EIN by company name?
Three official databases accept a company name and return an EIN: SEC EDGAR, EDGAR full-text search, and the IRS Tax Exempt Organization Search. All 3 cost $0. No state registry publishes an EIN.
| Database | Accepts a name | Returns an EIN | Official | Cost |
|---|---|---|---|---|
| SEC EDGAR company search | Yes | Yes, in the filing header | Yes | $0 |
| SEC EDGAR full-text search | Yes, filings from 2001 | Yes, inside the filing | Yes | $0 |
| IRS Tax Exempt Organization Search | Yes | Yes, for nonprofits | Yes | $0 |
| IRS Form 990 returns | Yes | Yes, item D on page 1 | Yes | $0 |
| Secretary of State business search | Yes, in all 50 states | No, never | Yes | $0 to a small fee |
| A public IRS search for private EINs | Not applicable | No, it does not exist | No | Not applicable |

Row 5 is the one that surprises people. A state registry holds the formation document, the registered agent, the filing history, and the status, because the state chartered the entity. It holds no EIN, because the EIN comes from the IRS through Form SS-4 after formation. All 50 states work this way.

Why does an EIN search by company name return nothing?
Five causes account for almost every empty result: the name searched is a brand, the company is private, the legal name changed, the entity files under a parent, or the business never received an EIN.
The name searched is a brand, not an entity. A brand carries no EIN because the IRS assigns numbers to legal entities. Search the name on the formation document, which is the name both EDGAR and the IRS index on.
The company is private. No public database lists private company EINs, so an empty result is the accurate result. A signed Form W-9 line 6 is the route, and it costs $0.
The legal name changed after the EIN issued. The EIN survives a name change and the record still holds the old name until Form 8822-B is processed. Searching the new name against an unamended record returns 0 rows.
The entity files under a parent. A subsidiary with no filer record of its own appears only inside the parent's filings. EDGAR full-text search reaches those filings from 2001 forward.
The business never received an EIN. A sole proprietor with no employees reports under a Social Security Number, so no EIN exists to find. Applying with Form SS-4 creates one, at $0 from the IRS.
A rejected new application produces its own class of confusion, because a name conflict inside the IRS system reads like a missing record. Read what each rejection code means on the ein reference number 101 page.
How many steps does an EIN search by company name take?
A nonprofit name resolves in 2 steps, a public company name in 3 steps, and a full-text search in 4 steps. A private company takes 3 steps, and 1 of them waits on the company.
| Route | Steps | Waits on anyone | Cost |
|---|---|---|---|
| Your own CP-575 or 147C letter | 1 step | No | $0 |
| IRS Tax Exempt Organization Search | 2 steps | No | $0 |
| SEC EDGAR company search | 3 steps | No | $0 |
| Form 990, item D on page 1 | 3 steps | No | $0 |
| EDGAR full-text search, 2001 forward | 4 steps | No | $0 |
| Signed Form W-9 from the company | 3 steps | Yes | $0 |

Five of the 6 routes take 4 steps or fewer and wait on nobody. Only route 5 involves another party, which is why it belongs last in the order and first in the planning: send the W-9 request at the start, then work the published sources while it sits in someone else’s inbox.
Is it legal to search for another company’s EIN?
Yes when the source is public. SEC filings, IRS Form 990 returns, and the Tax Exempt Organization Search are published records open to anyone at $0. Using another company’s EIN to file or transact is fraud.
The distinction is between reading and using. A vendor confirming a counterparty, a journalist tracing an ownership chain, and a payer preparing a Form 1099 all read published records for a legitimate reason, and the SEC and the IRS publish those records precisely so that they can be read.
An EIN alone is not a credential. It opens no account and authorises no filing on its own, because a bank pairs the 9 digits against the CP-575 and the exact legal name before any account opens. That pairing requirement is what keeps a published EIN from being a key to anything.
Treat your own EIN with the same posture. Give it on a Form W-9 to a party that will report a payment, and withhold it from a party with no reporting reason to hold it.
What does an EIN search by company name cost?
It costs $0 through all 6 routes. SEC EDGAR, EDGAR full-text search, the IRS Tax Exempt Organization Search, Form 990, and a signed Form W-9 each carry no fee, and the IRS charges $0 for a 147C letter.
Paid aggregators exist because a free source is inconvenient rather than incomplete. They scrape the same SEC filings and the same Form 990 returns, then charge for a search box over the top. The record inside is the identical published document, and a fee adds nothing to its authority.
One number is worth checking against the source rather than a reseller. A 9-digit EIN read directly from a 10-K header or a Form 990 carries a filing date and a filer behind it. The same 9 digits inside an aggregator carry a scrape date and nothing else.
What do you do when the company has no EIN yet?
File Form SS-4. A name search finds a number that already exists, and a new entity applies for one instead. The IRS charges $0, and line 7b accepts the entry Foreign when the responsible party holds no SSN.
This is the outcome behind a large share of empty searches. A newly formed LLC that has not applied yet holds a state charter and no federal number. A sole proprietor who never hired anyone reports under a Social Security Number. In both cases the search worked correctly and the answer is that nothing has been assigned.
Applying without a Social Security Number
Form SS-4 line 7b accepts the word Foreign, so the IRS issues EINs to responsible parties who hold no SSN and no ITIN. The application moves from the online tool to fax. The IRS fax line is 855-641-6935 for entities based in a US state and 855-215-1627 for international applicants. The IRS international phone line is 267-941-1099. No identity document is filed with Form SS-4.
