Sooner or later, most landlords receive an application from someone who leaves the Social Security number field blank. The applicant might be a graduate student, a relocating professional, or someone who files taxes with an Individual Taxpayer Identification Number (ITIN) instead of a Social Security number (SSN). Rejecting the application because the usual screening path does not fit can cost you a good renter and, in some places, create legal exposure. This guide explains what the law generally says about requiring an SSN, what an ITIN is and is not, and how to evaluate these applicants with the same rigor and the same standards you use for everyone else. For the broader screening process, the Tenant Screening Hub covers reports, criteria and workflow in more depth.
Note: This article is general education, not legal advice. Fair housing, privacy and screening rules vary by state and municipality and change over time. Consult a qualified attorney in your area before you adopt or change an SSN policy, and especially before you ask any question that touches on immigration or citizenship status.
Can a landlord require a Social Security number?
There is no federal law that generally requires a renter to have a Social Security number in order to lease a home, and there is no federal rule that says a landlord must collect one. Landlords ask for an SSN mostly because it is a convenient key for pulling credit reports and matching public records. According to Experian, credit bureaus do not match information to a person's credit history using only the SSN; they also rely on name, recent addresses and date of birth, and it is possible to have a credit report and a credit score without an SSN at all.
Whether you may insist on an SSN depends on where your property is. Some states and cities restrict what landlords can ask, limit how SSNs may be collected or stored, or require landlords to accept alternatives. Because this area keeps moving, check your current state and local rules before you print "SSN required" on an application.
California's limits on immigration and citizenship questions
California is the clearest example of a state that draws a firm line. California Civil Code Section 1940.3 prohibits landlords from making any inquiry regarding or based on the immigration or citizenship status of a tenant or prospective tenant, and from requiring an applicant to make any statement or certification about that status. The statute does allow landlords to request information or documentation needed to verify a prospective renter's financial qualifications or identity. In practice, that means a California landlord can verify income and identity but should not ask about, or try to infer, immigration status. Other jurisdictions have similar protections.
What not to ask
Keep your application focused on whether the applicant can pay rent and care for the home. Do not ask about immigration or citizenship status where it is prohibited, and do not treat a missing SSN as a stand-in for that question. If you ever believe you have a legal obligation to request status information, talk to counsel first rather than improvising.
What an ITIN is, according to the IRS
Per the IRS, an Individual Taxpayer Identification Number is a nine-digit tax processing number, formatted like an SSN and always beginning with the number 9, issued to people who need a U.S. taxpayer identification number but are not eligible for a Social Security number. The IRS states that the number is issued for federal tax purposes only, and that people can apply regardless of immigration status.
The IRS is equally clear about what an ITIN does not do. It does not authorize work in the United States, does not provide or change immigration status, does not qualify the holder for Social Security benefits, and does not serve as identification outside the federal tax system. For a landlord, the practical point is narrow: an ITIN can be a useful identifier for matching records and, where a screening provider supports it, for searching credit files. It tells you nothing about immigration status, and you should not treat it as if it does.
Why fair housing risk matters here
The federal Fair Housing Act, which HUD enforces, makes it unlawful to refuse to rent or otherwise make housing unavailable because of national origin, and to publish any statement or advertisement indicating a preference or limitation based on national origin. A blanket "no SSN, no lease" policy does not mention national origin, but it can fall hardest on applicants born outside the United States. Fair housing law can reach policies with a discriminatory effect, not only those written with discriminatory intent.
HUD has withdrawn a number of fair housing guidance documents since 2025, so do not rely on an older HUD guidance memo as your only reference point. The statute itself has not changed, and many state and local fair housing laws add their own protections, sometimes including immigration status or citizenship as protected characteristics. Our fair housing compliance guide walks through the protected classes and the habits that reduce discrimination risk.
The safest operational principle is consistency. Write down your screening criteria before you list the unit, apply the same criteria to every applicant, and document how each decision was reached.
Alternative evidence that answers the same questions
Screening exists to answer a few basic questions: Is this person who they say they are? Can they afford the rent? Have they paid housing costs and other obligations reliably? Will they take care of the home? An SSN is one route to those answers, not the only one, and the strongest files combine several of the options below.
Credit history from other sources
Some applicants with ITINs have U.S. credit files built from credit cards, auto loans or other accounts, and some screening providers can search for those files using an ITIN along with name, address and date of birth. Ask your provider directly whether it supports ITIN searches before you promise anything to an applicant. Applicants who recently moved from another country may be able to obtain a credit report from that country, and some services specialize in translating foreign credit histories into a format U.S. landlords can read.
Proof of income and bank statements
Recent pay stubs, an offer letter, tax returns filed with an ITIN, or several months of bank statements can show that the applicant earns enough and manages money responsibly. Apply the same rent-to-income standard you use for every applicant. Our guide to income verification for rental applications covers what to request and how to review it, and it is worth learning how to spot fake pay stubs so that alternative documents get the same scrutiny as standard ones.
Employment verification
A direct confirmation from an employer, or a formal verification report, confirms that the job and income are real. For relocating professionals, a letter from the new employer confirming role, salary and start date is strong evidence.
Prior landlord references
A reference from a previous landlord, including one outside the United States, speaks directly to the question you care about most: did this person pay rent on time and leave the home in good condition? Ask the same questions you ask for every applicant.
Photo identification
A passport, a state-issued ID or another government photo ID lets you confirm identity without asking about status. In California, verifying identity is expressly permitted by Section 1940.3, but asking about immigration status is not, so keep the purpose of the request limited to identity.
Deposits and guarantors, used carefully
When an applicant has limited verifiable history, landlords often consider a larger security deposit or a guarantor. Both can be reasonable, with two caveats.
First, many states cap security deposits. California, for example, generally limits most landlords to one month's rent under a law that took effect in July 2024, with a narrow exception for certain small landlords. Check our overview of security deposit laws by state and your local rules before you set any amount above your standard deposit.
Second, any condition you add must be tied to the risk factor you measured, such as no verifiable credit history, and applied to every applicant with that same risk factor. Requiring a higher deposit or a guarantor only from applicants without an SSN, while waiving it for U.S.-born applicants with equally thin credit, is the kind of inconsistency that creates fair housing exposure. A written policy that says, for example, "applicants without a verifiable credit history may qualify with a guarantor who meets our income standard" applies to everyone and is far easier to defend.
Keep the decision documented and the adverse action process clean
If you deny an application or add conditions based in whole or in part on information in a consumer report, the Fair Credit Reporting Act requires an adverse action notice, as the FTC explains in its guidance for landlords who use consumer reports. Either way, a short written record of the criteria, evidence and reason for each decision protects you if it is ever questioned. The tenant screening compliance requirements playbook covers notices and record-keeping in more detail.
Frequently asked questions
Is it legal to require a Social Security number on a rental application?
No federal law generally requires renters to have an SSN, and some states and cities restrict what landlords may ask or require them to accept alternatives. Check your state and local rules, and consult an attorney before making an SSN mandatory.
Can you run a credit check on a renter with an ITIN?
Sometimes. Some people with ITINs have U.S. credit files, and some screening providers can search with an ITIN plus name, address and date of birth, so ask your provider whether it supports ITIN searches.
What can landlords use instead of a credit report for applicants without an SSN?
Bank statements, pay stubs or an employer offer letter, employment verification, prior landlord references, a foreign credit report and a qualified guarantor can all show ability and willingness to pay. Apply the same written standards you use for every applicant.
Can landlords ask rental applicants about immigration status?
In some states, including California, landlords are prohibited from asking about immigration or citizenship status, though they may verify identity and financial qualifications. Where the rules are unclear, do not ask, and consult counsel.
What to do next
Applicants without a Social Security number are not automatically higher risk; they simply need a different route to the same answers. The real operational problem is keeping that alternative route organized and consistent, so every applicant is judged by the same written criteria and every decision is backed by documents you can find later.
Shuk's tenant screening lets you set your own pass criteria, including minimum credit score, rent-to-income ratio and your policies on bankruptcies, evictions, smoking, pets and renter's insurance, so your standards are written down before the first application arrives. You can request documents from applicants, including a photo ID, proof of income, a landlord letter of reference and a free-text extra document, which is where bank statements or an employer letter can be requested. Optional income verification and employment verification reports, paid by the applicant, add another layer of evidence. Shuk never auto-approves or denies; you make the final decision, and when you decline, the rejection reasons you select are disclosed to the renter. Once approved, leases can be signed through e-signature powered by Adobe and stored with the property.
At as low as $2 per unit per month, with no setup fees and no contract, and with White Glove Onboarding included at no additional cost, Shuk makes consistent, well-documented screening of every applicant feasible for landlords and property managers running 1 to 100 units.
