You can run a background check with an ITIN number for the criminal portion, because criminal records are searched by name, date of birth, and address rather than by any taxpayer number. The credit portion is a different story: an Individual Taxpayer Identification Number submitted in place of a Social Security Number will usually return no results, partial data, or an outright error. And for employers, an ITIN is never a substitute for an SSN when it comes to confirming work authorization. The real question isn’t whether an ITIN “works” as an SSN; it’s which parts of a screening depend on a number at all.
Criminal Searches Don’t Need Your SSN or ITIN
This is the piece most people worry about, and the answer is simple. County, state, and federal criminal record searches run on name, date of birth, and sometimes prior addresses. An SSN, when available, helps the screening company confirm that a hit actually belongs to the right person, but the number itself isn’t what pulls the record from the database.
So a background check company can run a criminal search for someone who provides only an ITIN, or no number at all. The trade-off is accuracy. Without an SSN to cross-reference, there’s a higher chance of returning records belonging to someone with the same name, or missing records filed under a name variation. Common names make this worse. Reputable screeners narrow results using additional identifiers like aliases and prior addresses.
The FBI’s Identity History Summary is a separate matter — it’s matched by fingerprints, not by any number, so neither an SSN nor an ITIN is relevant to that search.1Federal Bureau of Investigation. Identity History Summary Checks Frequently Asked Questions
Where Credit Checks Break Down
Credit is where the ITIN question gets tricky. The three major credit bureaus can technically build credit files linked to ITINs, and some lenders do report account activity under them. But pulling a credit report with an ITIN in place of an SSN is unreliable. Experian has stated that an ITIN entered in the Social Security Number field would be “recognized as an invalid Social Security number.”2Experian. Can You Check Your Credit Score Without a Social Security Number? A credit check run on an ITIN often returns no data, partial data, or simply fails to process.
An ITIN holder who has been building credit with lenders that report under the ITIN may well have a file. Whether a landlord’s or employer’s screening platform can reach it depends on how the query is submitted. Many systems only accept SSN-formatted numbers, and an ITIN pushed into that field won’t match. If you need your own credit report and don’t have an SSN, Experian lets you request it by mail with a government-issued ID and a recent utility bill or bank statement.2Experian. Can You Check Your Credit Score Without a Social Security Number?
For a landlord or employer running a credit check on an applicant with only an ITIN, the realistic expectation is an empty result. That isn’t a sign of bad credit; it means the system wasn’t designed for ITIN-based lookups.
For Employers: An ITIN Is Not Work Authorization
This is the mistake with the biggest consequences. A background check and employment eligibility verification are two separate processes, and ITINs behave very differently in each.
For the background check itself, the rules above apply: criminal searches are name-based, credit searches will likely fail. The more important issue is Form I-9. Every U.S. employer must verify that new hires are authorized to work, and ITINs do not play a role in that process. The IRS issues ITINs strictly for federal tax purposes. An ITIN does not authorize work in the United States, does not serve as identification outside the tax system, and does not qualify the holder for Social Security benefits.3Internal Revenue Service. Individual Taxpayer Identification Number
E-Verify will not accept an ITIN. The system requires a valid Social Security Number to create a case, and an ITIN card is not an acceptable document for Form I-9.4E-Verify. My Employee Entered a Set of Numbers in the Social Security Number Field on Form I-9 If an employee presents an ITIN card instead of a valid List A, B, or C document, the employer must ask for acceptable employment authorization documentation from the official Form I-9 list.5USCIS. Form I-9 Acceptable Documents An employer who confuses the two risks both I-9 compliance violations and E-Verify processing failures.
For Landlords: What to Do When the Credit Report Comes Back Empty
Landlords screening a rental applicant with an ITIN face a practical gap. The criminal portion of the tenant background check will work normally. The credit check will probably return no data. That leaves incomplete information, which is frustrating but does not by itself create a legal basis to reject the applicant.
How you handle the gap matters. The Fair Housing Act prohibits housing discrimination based on race, color, religion, sex, national origin, familial status, and disability.6Office of the Law Revision Counsel. 42 US Code 3604 – Discrimination in the Sale or Rental of Housing and Other Prohibited Practices Immigration status isn’t explicitly listed, but the Department of Justice has noted that national origin discrimination can include bias based on a person’s country of birth or ancestry.7Department of Justice. The Fair Housing Act Applying different screening standards to ITIN holders could overlap with national origin discrimination if it disproportionately affects applicants from certain countries. Safest approach: apply the same criteria to everyone. If a credit report comes back empty for an ITIN holder, consider alternative evidence of financial responsibility like bank statements or rental payment history, provided you offer the same flexibility to any applicant whose credit check returns insufficient data.
The Fair Credit Reporting Act applies to tenant screening the same way it applies to employment screening. A landlord using a third-party screening company must provide written disclosure to the applicant and get authorization before pulling the report. If the application is denied based on the screening, the applicant must get notice of the adverse action, the name of the reporting agency, and a statement that the agency didn’t make the decision.8Office of the Law Revision Counsel. 15 US Code 1681m – Requirements on Users of Consumer Reports
Your Rights as the Person Being Screened
Whether a background check uses your SSN, your ITIN, or just your name, the Fair Credit Reporting Act protects you the same way. Consumer reporting agencies must follow reasonable procedures to assure maximum possible accuracy of the information in their reports.9Office of the Law Revision Counsel. 15 US Code 1681e – Compliance Procedures For ITIN holders, where the absence of an SSN raises the risk of mismatched records, that accuracy obligation matters even more.
Before pulling a consumer report for employment, the employer must give you a clear written disclosure on a standalone document and get your written authorization. Landlords and creditors need a permissible purpose, such as evaluating your rental application or a credit transaction you initiated.10Office of the Law Revision Counsel. 15 USC 1681b – Permissible Purposes of Consumer Reports
If someone takes adverse action against you based on a consumer report — denying you a job, an apartment, or credit — they must notify you, identify the reporting agency, and tell you that you have the right to a free copy of your report within 60 days and to dispute any inaccurate information.8Office of the Law Revision Counsel. 15 US Code 1681m – Requirements on Users of Consumer Reports These rights apply regardless of whether you have an SSN or an ITIN. If the check returns inaccurate results because your ITIN was confused with someone else’s records, you can dispute those errors directly with the reporting agency.
Should You Even Hand Over Your ITIN?
Because an ITIN won’t improve the results of most background checks, there’s rarely a strong reason to provide it to a landlord or screening company. If an application asks for a “Social Security Number,” putting your ITIN in that field is more likely to cause processing errors than to help. Ask whether the screening can be run by name and date of birth instead. For identity verification, a passport or other government-issued ID will often do the work without feeding your tax identification number into a system that wasn’t built to handle it.
The ITIN itself carries a confidentiality dimension most people don’t think about. Tax returns and return information are protected under federal law, and because the IRS issues ITINs through the tax filing process, the number sits inside that framework.11Office of the Law Revision Counsel. 26 US Code 6103 – Confidentiality and Disclosure of Returns and Return Information That protection runs against government disclosure, not against a private landlord asking you for the number. But it’s a reminder that your ITIN is tied to your tax record in a way an SSN on a rental application is not, and treating it with care is reasonable.
