Find an EIN for a public company, a 501(c)(3) nonprofit, or your own business. Public-company EINs appear in SEC filings; nonprofit EINs are in the IRS Tax Exempt Organization Search. For private LLCs, the EIN is not publicly listed - see the lookup-channel matrix below.
Start by naming the entity: a public company, a 501(c)(3) nonprofit, your own business, or a private business you do not own. The entity type decides everything, because only two categories have publicly searchable EINs. Public companies disclose their EIN in SEC filings and nonprofits disclose it in the IRS Tax Exempt Organization Search. A private business EIN is not published anywhere, and the IRS keeps no public database of it.
Match the entity type to its lookup channel. Use SEC EDGAR for a public company, the IRS Tax Exempt Organization Search for a nonprofit, and your own CP-575 confirmation letter or a bank statement for your own LLC. If you lost your CP-575, the recovery channel is a Form 147C request to the IRS Business & Specialty Tax Line at 800-829-4933. Each channel serves a different entity type, and no single channel covers them all.
The live tool deep-links to the correct database based on your inputs, so you land on the SEC EDGAR search or the IRS Exempt Organization Search rather than hunting for it. For your own lost EIN, the tool routes you to the Form 147C recovery instructions. The goal is to send you to the one channel that can actually return the number for the entity type you selected.
If you are recovering your own EIN, follow the Form 147C process; the IRS faxes or mails the confirmation. If you are verifying a vendor's EIN from a W-9, use IRS TIN Matching rather than an open search, since no public lookup exists for a private vendor. Anonymousllc.co keeps a copy of every EIN it files, so its clients recover theirs at no cost, and a new EIN application is $99 flat.

EINs of public companies appear in SEC filings (10-K, 10-Q, etc.). 501(c)(3) nonprofit EINs are public via IRS Exempt Organization Search. Private business EINs are NOT publicly listed - the IRS does not maintain a public database of private business EINs. If you've lost your own EIN, request Form 147C from the IRS Business & Specialty Tax Line.
Private LLC EINs are not searchable because the IRS keeps no public database of them. Unlike the entity-registration databases at state Secretaries of State, there is no federal directory that maps a private business to its EIN. This is by design. An EIN is a tax identifier, and publishing a directory would expose businesses to fraud and identity theft. There is no lawful way to pull a competitor's EIN without an authorized purpose. The channels in the matrix above cover only public companies, which disclose the number in SEC filings, nonprofits, which disclose it in the IRS Exempt Organization Search, and recovery of an EIN you own.
Recover a lost EIN by requesting Form 147C from the IRS Business & Specialty Tax Line at 800-829-4933. The IRS faxes or mails the confirmation to the entity of record. The 147C letter is the official replacement for a lost CP-575, which the IRS issues only once at the time the EIN is assigned. Before calling, check a prior tax return, a bank account opening document, or a past business loan application, since the EIN appears on all of them. Anonymousllc.co keeps a copy of every EIN it files, so its clients request a resend at any time at no cost instead of calling the IRS.
A public company's EIN appears on the cover page of its 10-K and 10-Q filings, labeled 'IRS Employer Identification No.' just below the state of incorporation. SEC EDGAR is the free, reliable channel for this, because public reporting companies are required to disclose the identifier. Search the company name in EDGAR, open the most recent annual or quarterly report, and read the cover page. This is the only broadly available free EIN lookup, and it works precisely because public companies have a disclosure obligation that private LLCs do not.
Verify a vendor's EIN with IRS TIN Matching, which checks a name and EIN against IRS records for enrolled filers. There is no open public lookup that returns a private vendor's EIN. TIN Matching is available to payers who file information returns and enroll in the IRS e-Services program, and it confirms whether a name-and-number combination is valid before you issue a 1099. Banking partners also verify EINs inside their know-your-business workflows when onboarding a business account. For a one-off check, the W-9 the vendor signs is the primary record, and TIN Matching confirms it against IRS data.
Find a 501(c)(3) nonprofit's EIN through the IRS Tax Exempt Organization Search at apps.irs.gov/app/eos. Nonprofit EINs are public because tax-exempt organizations file disclosable returns. Search by organization name or location, open the record, and the EIN appears alongside the organization's filing history, including its Form 990. This transparency is a condition of tax-exempt status, which is why nonprofit EINs sit in the small category of publicly searchable numbers next to public-company EINs. A private LLC, by contrast, files no disclosable return that would surface its EIN.
Yes. An anonymous LLC's EIN is not published in any public database, and forming anonymously keeps the members off the public state filing as well. The EIN is known to the owner, the IRS, and the LLC's bank. An EIN identifies the entity, not the individual owners, so even if a number were known it would not reveal who owns the LLC. Combined with formation in an anonymous state, where members and managers stay off the Articles of Organization, the EIN adds no public exposure. Anonymousllc.co obtains the EIN as part of formation and for a $99 flat standalone fee, and it stores the confirmation for the client's later use.
