Can you register a car and get plates without a Social Security number?

Registering a car without a Social Security number: title and registration are separate documents with separate rules, and what Texas now requires.

Before the answer, two documents have to be pulled apart, because almost everyone conflates them: the title and the registration are not the same thing, and their rules differ. On the Social Security number, federal law commands nothing: 42 U.S.C. §405(c)(2)(C)(i) permits states to require one, and that is where the national rule ends. Everything else is decided state by state — and in Texas the difference between titling and registering was put in writing on February 27, 2026, effective March 5, 2026.

This page explains what each document is, what federal law actually says, and how two large states whose rules we could read handle it. It is not a 50-state table: there is no federal list, and we are not going to invent the states we did not verify. (Verified August 11, 2026.)

Title and registration: two documents, two transactions

	Title	Registration
What it establishes	Who owns the vehicle	Permission to use public roads
What it produces	A certificate of ownership	The plates and sticker, renewed on a cycle
Texas identification	Accepts “United States or foreign passport” (43 TAC §217.5(d)(1))	Since March 5, 2026, a foreign passport must be accompanied by a DHS document
Insurance	Texas has a “title only” path with no proof of insurance	Texas requires proof of liability insurance

There is no federal definition of “title” versus “registration.” This separation comes from the state agencies whose rules we read — Texas and New York — not from a national rule, and that is how we present it.

What federal law says: permission for the states, not a mandate

The full text is long, and the load is carried by the verb:

“It is the policy of the United States that any State (or political subdivision thereof) may, in the administration of any tax, general public assistance, driver’s license, or motor vehicle registration law within its jurisdiction, utilize the social security account numbers issued by the Commissioner of Social Security for the purpose of establishing the identification of individuals affected by such law, and may require any individual who is or appears to be so affected to furnish to such State … the social security account number … issued to him by the Commissioner of Social Security.” — 42 U.S.C. §405(c)(2)(C)(i)

California’s DMV cites that same provision as its own authority: “Federal law also allows any state to use a person’s SSN for the purpose of establishing his/her identification. (42 U.S.C. §405(c)(2)(C)(i))”.

Read it for what it is: an authorization to the states. It does not convert into a national statement in either direction — it neither requires an SSN nor forbids asking for one.

California: the SSN rule is written about the license and ID card, not the vehicle

The California DMV’s Social Security number fact sheet (Fast Facts 8, revised January 2020) is blunt:

“All applicants for a driver license and/or identification (DL/ID) card must submit his/her social security number to DMV.” “If you refuse to disclose your SSN, you will not be able to start any DL/ID card application.”

Now the detail that matters and that almost nobody points out: the fact sheet’s scope is the driver license and the ID card, start to finish. It never mentions vehicle registration or title.

That is what the source says and what it does not say. We did not find an affirmative California statement that vehicle registration requires no SSN, so we do not write one here. The vehicle-registration pages on dmv.ca.gov could not be read in this review: they returned navigation shells only, and the specific private-party registration addresses returned 404. A block is not evidence of anything — it is only the reason we do not assert.

Texas drew the line between titling and registering, in writing

This is the clearest text that exists today on the subject, and it comes from the preamble with which TxDMV adopted its rules (published February 27, 2026):

“People can continue using foreign passports to obtain legal title to purchased vehicles, so that they can export them to their home country or sell the vehicle if they are unable to use it. Under Transportation Code §502.040, people who are not legally eligible to reside in Texas are not authorized to register vehicles as Texas residents.”

A state agency is stating, in an official document, that titling and registering are separate things and that immigration eligibility bears on one and not the other. That is why this page starts with the distinction: in Texas it is now the decisive one.

Identification for a TITLE in Texas

The title identification rule, 43 TAC §217.5(d)(1), lists the acceptable photo identification: a driver’s license or state identification certificate issued by a US state or territory; “United States or foreign passport”; a US military identification card; NATO identification or identification issued under a Status of Forces Agreement; a Department of Homeland Security, USCIS or Department of State identification document; or a license to carry a handgun issued by the Texas Department of Public Safety. (Rule history: effective March 12, 2015, amended in 2016, 2022 and on November 14, 2024.)

On that list, the foreign passport stands alone, with no accompanying-document condition.

Identification for REGISTRATION in Texas — changed March 5, 2026

Here is the recent change behind this page. TxDMV adopted amendments to 43 TAC §§217.22, 217.26 and 217.29 “with changes to the proposed text as published in the December 5, 2025, issue of the Texas Register (50 TexReg 7868)”, and set the dates as follows:

“The effective date for the amendments to §217.22 and §217.26 is March 5, 2026. The effective date for the amendments to §217.28 and §217.29 is January 1, 2027.”

Since March 5, 2026, per the preamble, an applicant for vehicle registration under Transportation Code Chapter 502 must present one of five types of identification:

A valid, unexpired driver’s license or state identification certificate that complies with REAL ID, is not marked “limited term” or “temporary,” and was issued by a US state or territory.
A valid, unexpired driver’s license or state identification certificate issued by a state that requires proof of legal presence in the United States for issuance.
A valid, unexpired driver’s license or state identification certificate from any US state or territory — REAL ID compliant or not — accompanied by a United States birth certificate as defined in new §217.22(45), a United States Certificate of Naturalization (N-550 or N-570), or a United States Certificate of Citizenship (N-560 or N-561).
A valid passport.
A valid, unexpired license to carry a handgun issued by the Texas Department of Public Safety.

The definition of valid passport is what changes everything for a foreign passport:

“Valid passport– (A) An unexpired passport or passport card issued by the United States government; or (B) An unexpired passport issued by the government of another country accompanied by one of the following documents issued by the United States Department of Homeland Security: (i) Form I-94, unless the Form I-94 shows that the bearer only has Parole status;”

Three things worth reading slowly:

A US passport stands alone. A foreign passport no longer does: it must be accompanied by a DHS document.
The definition expressly excludes a Form I-94 showing only parole status.
The list of DHS documents continues past item (i); see the full adopted text in the Texas Register for the whole list. We reproduce only what we verified.

One drafting detail the agency explained itself: the passport-stamp requirement was dropped at adoption because “the department learned through public comment that the federal government no longer stamps passports but instead uses the Form I-94.”

How many people it reaches, in the state’s own numbers. TxDMV published its estimate in the same document: “only 5.15% of registrants who completed initial registration and titling simultaneously used a passport as their form of identification” and “the department expects that the rule will impact approximately 1.29% of registered vehicles, or about 341,000 vehicles per year, resulting in a reduction in vehicle registration revenue to the state of approximately $19.5 million per year, or 0.84%.”

📅 Watch: the amendments to 43 TAC §§217.28 and 217.29 take effect January 1, 2027. The above describes the state of the rules as of August 11, 2026.

New York solves identification a different way. To register or title, the DMV asks for two things:

“To register a vehicle or get a title, you need to prove your date of birth (DOB) by providing one acceptable document from the list below … name by providing one or more documents that total 6 points.”

And it adds: “A New York State license, permit, or ID that is current or expired for less than 2 years meets both requirements.” In other words, the state license is one route, not the requirement.

The Social Security card appears in that table as one option among roughly forty, and it does not even work for date of birth:

Document	Name points	Valid proof of date of birth?
Valid Employment Authorization Card with photo (I-688B or I-766), issued by DHS	3	Yes
Permanent Resident Card (I-551)	3	Yes
Reentry Permit (I-327)	3	Yes
Refugee Travel Document (I-571)	3	Yes
Foreign passport with a valid I-551 stamp or with a statement on the visa (in English or translated by an embassy)	3	Yes
Foreign passport with a visa and a valid I-94 issued by DHS (in English or translated by an embassy)	3	Yes
US Social Security card (must have signature)	2	No
Valid Canadian passport (without DHS documentation)	0	—

⚠️ The limit, stated plainly: a foreign passport without a DHS document is not on that list, and neither is a matrícula consular. Do not read it any other way.

⚠️ And a reading trap: the word Consular does appear once in New York’s table — “US DOS Consular Report of Birth Abroad (FS-240, DS-1350, F-545)”. That is a birth document for US citizens born abroad, worth 0 name points, and it is not a matrícula consular.

Insurance and plates: in Texas they travel together, and there is a “title only” path

TxDMV puts it in one sentence:

“You must provide proof of liability insurance when you title and register your vehicle. If you do not provide proof of insurance, you may apply for ‘title only’.”

And at renewal: “To register your vehicle in person, take your registration renewal notice and proof of current liability insurance to your county tax office or an approved substation.”

That is the hinge between the two halves of this subject: a title can be obtained without proof of insurance; a registration cannot. How insurance works on its own — including the part almost nobody writes down, that the financial-responsibility duty attaches to the vehicle’s owner — is covered in car insurance without a driver’s license.

And that link between insurance and registration is not universal. In New Hampshire, proof of financial responsibility is a conditional, per-person obligation: the heading of the relevant state statute, RSA 264:2, reads “Proof Required Upon Conviction for Motor Vehicle Law Violations.”

The 30-day deadline — and why it matters to the seller too

A procedural fact that prevents real problems:

“Vehicles are required to be titled in the buyer’s name within 30 days from the date of sale. Failing to properly transfer a vehicle into the buyer’s name could result in the seller being held responsible for tickets, toll violations or even crimes committed with the vehicle.” — TxDMV

If the title is not transferred, the vehicle stays tied to the seller in the state’s records.

What the sources do not say

There is no national rule on whether a Social Security number is required to title or register a vehicle. 42 U.S.C. §405(c)(2)(C)(i) grants permission to the states and nothing more. We do not convert that permission into a national statement in either direction.
California: the source is silent. Fast Facts 8 addresses only driver license and ID card applications. We found no affirmative state statement about SSNs and vehicle registration.
No federal source defines “title” versus “registration.” The distinction on this page comes from state agencies and is attributed as such.
New York’s list does not include a matrícula consular or a bare foreign passport. We do not imply otherwise.
Illinois and Florida: not verified. We could not read the title and registration identification rules for those two states — the Illinois site refused our requests and the Florida pages returned navigation only. A block is not evidence that a rule runs one way or the other, and we make no claim about those states and do not generalize from the ones we could read.
We did not survey 50 states. The honest shape of this page is: here is the federal position (permission, nothing more), here is how two large states actually do it, and that is why the answer is genuinely state-specific. Start with your own state’s page.

Frequently asked questions

What is the difference between a car title and a car registration?

The title establishes who owns the vehicle; the registration is what allows it on public roads and is what produces the plates and sticker, renewed on a cycle. They are two separate transactions with separate requirements. Texas separated them explicitly in 2026: ‘People can continue using foreign passports to obtain legal title to purchased vehicles … Under Transportation Code §502.040, people who are not legally eligible to reside in Texas are not authorized to register vehicles as Texas residents.’

Does federal law require a Social Security number to register a car?

No. 42 U.S.C. §405(c)(2)(C)(i) says any State ‘may, in the administration of any tax, general public assistance, driver’s license, or motor vehicle registration law … require any individual who is or appears to be so affected to furnish … the social security account number.’ That is permission granted to the states, not a federal mandate. Each state decides, which is why the answer changes from state to state.

What documents does New York accept to register or title a vehicle?

New York uses a points system: ‘you need to prove your date of birth (DOB) by providing one acceptable document from the list below … name by providing one or more documents that total 6 points.’ The list includes the Employment Authorization Card (I-688B or I-766), the Permanent Resident Card (I-551), the Reentry Permit (I-327), the Refugee Travel Document (I-571), and a foreign passport accompanied by a visa and a valid I-94. A Social Security card is worth 2 points and is only one option among many. A foreign passport with no DHS document is not on the list.

Can a foreign passport be used to title a car in Texas?

The title identification rule, 43 TAC §217.5(d)(1), lists ‘United States or foreign passport’ among acceptable photo identification. Registration is a different matter: since March 5, 2026 the registration rule requires a foreign passport to be accompanied by a Department of Homeland Security document.

Do you need insurance to get plates?

In Texas yes, and there is a separate path for the title alone. TxDMV states it this way: ‘You must provide proof of liability insurance when you title and register your vehicle. If you do not provide proof of insurance, you may apply for title only.’ Rules vary by state: in New Hampshire, proof of financial responsibility is required after certain convictions rather than as a universal precondition.

How long is there to put the title in the buyer's name?

In Texas, 30 days. TxDMV also warns the seller: ‘Vehicles are required to be titled in the buyer’s name within 30 days from the date of sale. Failing to properly transfer a vehicle into the buyer’s name could result in the seller being held responsible for tickets, toll violations or even crimes committed with the vehicle.’
