In most of the US you can ask for a Social Security number, but asking and requiring are different things. Portland bars rejecting an applicant who has no SSN, California bars asking about immigration status, and Canada's privacy regulator says a landlord does not need a SIN at all. This is information, not legal advice.
Can a US landlord ask for a Social Security number?
Usually, yes. No federal law forbids the question, and tenant screening companies often use the number to match a credit file to the right person. The trouble starts when the SSN becomes a gate: a required field on the form, or a policy that sends every application without one to the bottom of the pile.
Plenty of qualified renters do not have an SSN. Some file taxes with an Individual Taxpayer Identification Number (ITIN). Some are new arrivals on a work visa. A blanket rule that turns them away can look like national origin discrimination, and national origin is one of the protected classes in the Fair Housing Act.
Where can you not reject an applicant without an SSN?
Portland is the clearest example. Under Portland City Code 30.01.086, a landlord may not reject an application as incomplete because the applicant or someone in the household does not produce a Social Security number or prove lawful presence in the US. The code also bars asking about immigration status at all.
Instead, you must accept any of these, alone or combined, to verify name, date of birth and photo:
| Accepted in Portland | Notes |
|---|---|
| Social Security card | Optional, never required |
| ITIN | The common substitute for credit matching |
| Permanent resident card | Valid receipt card |
| Immigrant or nonimmigrant visa | Either kind |
| Any government-issued ID | Even if expired |
| Nongovernmental ID | If it allows reasonable verification |
The expired-ID line surprises most managers. An out-of-date passport still proves who someone is, and Portland treats it that way.
Can you ask about immigration status?
Not in California. California Civil Code 1940.3 says a landlord or any agent of the landlord may not ask about the immigration or citizenship status of a tenant, applicant or occupant, and may not require them to make any statement about it.
The same section keeps the parts you actually need. You may still request information to verify an applicant's identity and financial qualifications. So the question "can you show us proof of income?" is fine. The question "are you a citizen?" is not. Federally funded programs with their own eligibility rules are the main exception.
Can a Canadian landlord require a SIN?
No. The Office of the Privacy Commissioner of Canada answers the question directly: a landlord does not require your Social Insurance Number. A basic credit check needs, at minimum, name, address and date of birth.
Unless a law requires the SIN or no other identifier would work, an applicant cannot be refused for declining to give it. A landlord may ask, but the regulator recommends against it, and the number should never become a general ID. British Columbia, Alberta and Quebec have their own private sector privacy laws with similar guidance.
Where does this go wrong in practice?
Two places. The first is the form. A required SSN or SIN field quietly rejects everyone without one before a person ever reads the file. Make the field optional, list the alternatives next to it, and keep copies only as long as you need them. Our guide on how long to keep applicant ID data covers the second half of that job.
The second is the first conversation. When a caller asks "do I need a social to apply?", whatever your team says becomes your policy. One agent says yes, another says no, and you now have two sets of criteria.
LetHub answers rental inquiries by text, chat and phone in about 30 seconds and gives every prospect the same answers you set for the unit, so the ID question gets one answer every time. Book a demo to see it on your listings.
SSN and rental applications: FAQ
Can I deny an applicant who will not give an SSN?
It depends on where the unit is. In Portland you cannot treat the application as incomplete for that reason and must accept alternatives such as an ITIN or any government ID. Elsewhere it may be allowed, but a blanket SSN requirement can raise national origin concerns under the Fair Housing Act.
Can I run a credit check with an ITIN?
Many screening providers accept an ITIN or match a file using name, date of birth and address history instead. Ask your provider which identifiers it supports before you write the rule into your criteria, so the form does not demand something your screening process does not need.
Can I ask if an applicant is a US citizen?
In California, no: Civil Code 1940.3 bars landlords and their agents from asking about immigration or citizenship status. Portland's code bars it too. You may still verify identity and income. Federal housing programs with their own eligibility rules are handled separately.
Does a landlord in Ontario or BC need my SIN?
No. The federal privacy regulator says a basic credit check needs only name, address and date of birth, and a landlord cannot refuse you for declining to give a SIN unless a law requires it. BC, Alberta and Quebec apply their own privacy laws with similar guidance.
