How are free EIN lookup sources ranked?
Free EIN lookup sources rank in 4 tiers by publisher. Tier 1 holds the 2 IRS-issued letters. Tier 2 holds 5 self-held records. Tier 3 holds 3 official public filings. Tier 4 holds the 2 that return no EIN.
| # | Tier | Free source | Covers | Authority | Time | Bank accepts | Cost |
|---|---|---|---|---|---|---|---|
| 1 | Tier 1 | CP-575 confirmation letter | Your own EIN | Issued by the IRS | 1 minute | Yes | $0 |
| 2 | Tier 1 | 147C verification letter | Your own EIN | Issued by the IRS | Days to weeks | Yes | $0 |
| 3 | Tier 2 | Form 1120 or Form 1065, page 1 | Your own EIN | Your filed copy | 2 minutes | No | $0 |
| 4 | Tier 2 | Form 941, page 1 | Your own EIN | Your filed copy | 2 minutes | No | $0 |
| 5 | Tier 2 | Form W-2, box b | An employer EIN | Your issued copy | 5 minutes | No | $0 |
| 6 | Tier 2 | Form W-9, line 6 | Any signer, private included | Signed by the holder | 5 minutes | No | $0 |
| 7 | Tier 2 | Business bank account file | Your own EIN | Bank-verified copy | 5 minutes | No | $0 |
| 8 | Tier 3 | SEC EDGAR filing header | Public companies | Published by the SEC | 3 minutes | No | $0 |
| 9 | Tier 3 | IRS Tax Exempt Organization Search | Registered nonprofits | Published by the IRS | 3 minutes | No | $0 |
| 10 | Tier 3 | IRS Form 990, page 1 | Tax-exempt filers | Published by the IRS | 3 minutes | No | $0 |
| 11 | Tier 4 | Secretary of State business registry | Nothing, no EIN is published | State agency, no EIN field | 0 results | No | $0 |
| 12 | Tier 4 | SAM.gov federal award records | Nothing, the TIN is withheld | Federal system, EIN masked | 0 results | No | $0 |
Sources: IRS forms and instructions, the SEC EDGAR system, and SAM.gov entity records, verified July 2026. Every ranked source sits in exactly 1 of the 4 tiers, and no fifth tier exists.
Read the table top to bottom rather than by category. Rank 1 answers the question in 1 minute with a document a bank accepts. Rank 12 answers it in 0 results. Ten rows sit between those two, and each one trades authority for reach: the further down the list a source sits, the more companies it covers and the less it proves.
What is the most reliable free EIN lookup?
The CP-575 confirmation letter ranks first. The IRS issues 1 CP-575 per EIN and prints the 9-digit number beside the legal name it assigned. The 147C letter ranks second and replaces it at $0.
Tier 1 exists because those 2 documents record the pairing at the source. The CP-575 records it at assignment. The 147C records it at reissue. Every other free source on this page is a copy of one of those 2 events, made by a taxpayer, a bank, or a payroll system.
The 1-per-EIN rule on the CP-575 explains the whole ranking. The IRS never reprints that letter, so a business that loses it holds copies and no original. Request the replacement through the 147C letter procedure, and read the anatomy of the original on the CP-575 page.
The 147C carries a cost of $0 and a wait measured in days to weeks. That wait is the only trade in Tier 1. A business with a bank appointment in 3 days reaches for the 5-minute Tier 2 records first and files the 147C request in parallel.
Which free EIN lookup finds your own number fastest?
A filed federal return finds it in 2 minutes. Form 1120, Form 1065, and Form 941 each print the EIN on page 1. Form W-2 box b and Form W-9 line 6 return it in 5 minutes.
| Tier 2 record | Where the EIN prints | Who holds a copy | Minutes |
|---|---|---|---|
| Form 1120 or Form 1065 | Page 1, identification block | The business and its accountant | 2 |
| Form 941 | Page 1, employer block | The business and its payroll provider | 2 |
| Form W-2 | Box b | Every employee issued one | 5 |
| Form W-9 | Line 6 | Every client who paid the business | 5 |
| Bank account file | The account application | The bank and the account signer | 5 |
Source: IRS forms and instructions, verified July 2026.
All 5 Tier 2 records carry the same 9 digits, so speed decides which one you open. The advantage of Tier 2 is distribution: 5 separate parties hold a copy, which is why a business that lost its own paperwork recovers the number from an accountant, a payroll provider, or a client inside 5 minutes.
The limit of Tier 2 is proof. A photocopy of a return demonstrates what the business reported and not what the IRS holds today. A legal name that changed after filing breaks that match, and the change is recorded on Form 8822-B. Panicked recovery order sits on the lost ein number page.
Which free EIN lookup covers a public company?
SEC EDGAR covers public companies at $0. The EIN prints in the filing header of every 10-K and 10-Q, labelled IRS Employer Identification No. A search takes 3 minutes and requires no account.
EDGAR is free because federal securities law compels the filing, not because an agency chose to publish a directory. That distinction sets the boundary of the source: EDGAR reaches the companies that file with the SEC and reaches 0 companies that do not.
Match the filer rather than the brand. A listed parent and its operating subsidiaries hold separate EINs, and the header of a 10-K carries the EIN of the registrant that signed it. A ticker symbol maps to 1 registrant, and a corporate group maps to many.
Which free EIN lookup covers a nonprofit?
Two IRS sources cover nonprofits at $0. Tax Exempt Organization Search returns the EIN of every registered tax-exempt organization. Form 990 prints the same EIN on page 1. Each search takes 3 minutes.
Nonprofits are the most openly published category because the annual Form 990 becomes a public document. That single rule puts 2 of the 12 sources on this page into Tier 3 and makes a charity EIN faster to confirm than a private company EIN of any size.
Search by legal name, not by campaign name. A national organization and its local chapter file separate Forms 990 under separate EINs, and a donor receipt names the entity that received the funds. Read what the public sees and does not see on the is ein public record page.
Which free EIN lookup covers a private company?
None of the 3 free public databases covers a private company. The route is Form W-9, line 6, signed by the company itself. That request costs $0 and produces a document the signer attests is correct.
A private company files no 10-K and no Form 990, so no agency publishes its EIN. The gap is structural and not a gap in coverage that a better tool closes. Any list of private company EINs was built from documents those companies released one at a time.
Form W-9 is the mechanism that releases them. A client, a vendor, or a payment processor requests one before issuing a payment, and line 6 carries the number. The request is routine, and a company that invoices US customers answers it every quarter. Work the name-based routes on the ein search by company name page, and confirm a counterparty on the verify ein number page.
Which free EIN lookups return 0 results?
Two of the 12 ranked sources return 0 EIN results by design: a Secretary of State registry and SAM.gov. Two unranked searches people also try, a county clerk record and a search engine query, return 0 as well.
The Secretary of State business registry. All 50 state registries publish the formation date, the registered agent, and the status. None publishes an EIN, because a state charters the entity and the IRS numbers it.
SAM.gov federal award records. SAM.gov identifies a federal contractor by a Unique Entity ID, not by an EIN. The registration collects a taxpayer ID and displays 0 digits of it in the public record. Source: SAM.gov entity records, verified July 2026.
A county clerk or DBA filing. A DBA carries no EIN of its own. The EIN belongs to the legal entity behind the trade name, so 1 entity with 4 DBAs still holds 1 EIN.
A search engine query for the company plus EIN. A search engine returns copies of the same 3 public databases. A private company EIN appears in 0 of them, so the query surfaces mirrors and no primary record.
A 0-result search is information rather than a failure. It confirms that the EIN you want sits in Tier 1 or Tier 2 documents, or behind a W-9 request. Reading a 0-result state search as a broken tool sends people to paid mirrors that hold the same 0 records.
Does a paid EIN lookup find more than a free one?
No. A paid lookup reads the same 3 free public databases: SEC EDGAR, IRS Tax Exempt Organization Search, and Form 990. Payment buys an interface. It adds 0 records that the free sources lack.
| Question | Free official sources | A paid lookup tool |
|---|---|---|
| Public company EINs | Yes, SEC EDGAR | Yes, copied from EDGAR |
| Nonprofit EINs | Yes, 2 IRS sources | Yes, copied from the IRS |
| Private company EINs | No, W-9 instead | No, W-9 instead |
| Your own EIN | Yes, CP-575 or 147C | No, the IRS releases it to you |
| Proves the EIN and legal name pairing | Yes, on 2 of 12 sources | No |
| Cost | $0 | A fee per search or per month |
Sources: IRS and SEC published records, verified July 2026.
The 1 case where money changes an outcome is a new EIN, not a lookup. A lookup recovers a number that already exists in IRS records. An entity that holds no EIN has nothing to recover at any price, and it applies on Form SS-4 instead. Compare what services charge on the ein cost page.
Which free EIN source does a bank accept?
Two of the 12: the CP-575 letter and the 147C letter. A bank tests the EIN against the exact legal name the IRS holds, and only those 2 documents carry that pairing from the IRS itself.
The test is character-level. A name filed as LLC and presented as L.L.C. fails the match, and the IRS derives a 4-character name control from the legal name to run it. That single rule causes the most common account-opening rejection, and the fix is documented on the irs name control page.
A screenshot fails for the same reason a photocopy of a return fails: it proves a number and proves no pairing. Different institutions ask for different documents, and the document each one accepts is catalogued on the ein verification requirements banks platforms page.
How do you spot an official free EIN source?
An official source runs on an irs.gov or sec.gov address and names the filing it draws from. Five of the 12 sources here are agency-published. A source that lists private company EINs mirrored one of those 5.
Check the publisher, not the price
All 12 sources cost $0, so a free label separates nothing. The IRS and the SEC publish 5 of them. The other 7 are documents a taxpayer or a counterparty already holds.
Check the coverage claim against the structure
No agency publishes private company EINs, so a database claiming full US coverage is describing scraped filings. The 3 public databases cover 2 categories: public companies and registered nonprofits.
Check whether the source names the underlying filing
An official record cites the 10-K, the Form 990, or the CP-575 behind the number. A mirror shows a 9-digit number with no filing attached and no date of record.
Never send identity documents to reach a number you already own
A CP-575, a 147C, and 5 Tier 2 records reach your own EIN with 0 identity uploads. The IRS releases the number to an authorized person over its own channels.
What do you do when every free EIN lookup returns nothing?
Two outcomes explain a total blank. An assigned EIN exists and needs a 147C letter at $0. No EIN was ever assigned, and Form SS-4 creates one, also at $0 from the IRS.
Separate the 2 cases before acting. A business that filed a federal return holds an EIN, and the 147C recovers it. A newly formed entity, a new LLC, or a sole proprietorship that never hired an employee holds none, and no lookup at any price produces one.
International callers reach the IRS at 267-941-1099. Decide whether a new number is required at all on the when do you need a new EIN page.
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. No identity document is filed with Form SS-4.
Have an SSN? irs.gov is free, and the online tool issues the EIN in 15 minutes. Read the full route on the ein without ssn page.
