The Alternative Identifier Route to a State License

Of all the obstacles to a professional license, the one that catches most people is a single blank field asking for a nine-digit number. It is not an immigration question, it was never intended as one, and for years it functioned as the most effective status test in state licensing precisely because nobody thought of it that way.

Where the requirement comes from

The origin is a federal child support enforcement scheme. States receive federal funding for their child support programs on condition that they adopt a list of specified procedures, and one of those procedures is recording a social security number on applications for professional, occupational, recreational, marriage and driving licenses.

The purpose is straightforward. If a licensing agency holds the number, the child support agency can match records, identify a licensee in arrears, and ask the licensing agency to suspend the license. The number is a matching key. Nothing in the provision concerns immigration, and nothing in it directs a state to refuse a license to anyone.

The consequence arose sideways. A social security number is issued for work purposes only to people with work authorization, so a mandatory field asking for one excludes everyone who has never held it — including people whose licensure the state has no policy interest in preventing, and including people whose state has expressly decided not to condition licensure on status at all.

Boards implementing the requirement generally reproduced the federal wording in their own statutes or rules, which is why the field is so uniform across states and professions that otherwise share nothing.

What the fix looks like

The states that addressed this did it in one of two ways, and both are legislative rather than administrative.

The first is to name a second acceptable identifier. The statute is amended to require a social security number or an individual taxpayer identification number, leaving the child support matching function intact because the tax number is equally usable as a key. This is the more common approach and the more durable one, because it preserves the federal scheme rather than creating an exception to it.

The second is to permit the requirement to be satisfied by a declaration that no number has been issued, in the same way the federal identity-card standard does. This is less common in licensing and leaves the matching function without a key, which is why fewer states chose it.

What no state can do is fix the problem by board policy. The requirement sits in statute, it exists to satisfy a federal funding condition, and a board that waives it administratively is exposing the state's funding rather than solving an applicant's problem. Applicants sometimes press for this and boards sometimes concede it; neither outcome is stable.

Where a state has created the alternative, applicants should expect the form to catch up slowly. Printed applications and online systems are frequently a version behind the statute, and a field that still refuses anything but nine digits in the old format is a software problem rather than a legal one. Raising it with the board in writing generally produces a workaround.

What the alternative does not do

An individual taxpayer identification number is a tax processing number. It exists so that a person with a United States filing obligation can meet it, and it is issued to people who are not eligible for a social security number. That is its entire function.

It does not authorize employment. It does not confer status. It does not make its holder eligible for benefits that depend on work authorization, and it does not appear in the federal verification systems that a state queries when a status condition applies.

That last point is the one that produces disappointment. Satisfying the identifier requirement removes one obstacle. Where the same state's licensing statute also conditions the license on lawful presence, the applicant has cleared a field and not a condition, and the verification query will proceed as before. The two requirements are independent, and the states that opened licensure generally addressed both in the same enactment precisely because addressing one alone achieves little. Which condition a given state applies is the subject of whether a licensing board may ask about immigration status.

Where an applicant holds a tax number and is uncertain whether the state's licensing statute also imposes a status condition, that is a question worth resolving before filing rather than by experiment; an immigration lawyer who advises applicants without a social security number can read the two provisions together in a single sitting.

Obtaining and maintaining the number

An individual taxpayer identification number is obtained by application to the federal tax authority, generally submitted with a tax return, and supported by original identity and foreign status documents or certified copies from the issuing agency. Applications can also be made through authorized acceptance agents, which avoids sending original passports through the post — a practical consideration that matters more than it sounds when the passport is also needed for a licensing appointment.

Processing takes weeks rather than days, and longer in the filing season. Anyone planning a licensure application in a state that accepts the alternative should start the number application well ahead of the licensing timetable, because the two cannot be run in parallel: the license application needs the number in hand.

The number can also expire. Numbers not used on a federal tax return for a period of consecutive years are deactivated, and a deactivated number will not satisfy a licensing requirement or a renewal. Reactivation is a renewal application with its own processing time. A licensee who obtained the number for a license and has no filing obligation should be aware that the number can lapse quietly between renewal cycles.

Finally, keep the correspondence. The notice assigning the number is the document a board will want, and reconstructing it later is slower than filing it away now. The same discipline applies to every state determination in this subject, for the reasons set out in the documents a state agency may require.

One consequence of the statutory route deserves separate mention, because it affects planning rather than paperwork. Where a state accepts the alternative identifier, the acceptance is generally written into the licensing chapter for named professions rather than for licensure at large. A nurse and an electrician in the same state can therefore face different answers, and a practitioner holding two licenses may satisfy the requirement for one and not the other. The list of covered professions is the thing to read, not the headline of the amending act.

The same fragmentation appears on renewal. A statute that opened initial licensure does not always speak to renewal, and boards have occasionally read the silence as leaving the original requirement in place for renewals. That reading is hard to defend but it has to be dealt with when it appears, and the practical answer is the same as elsewhere: ask the board in writing which provision it is applying, well before the renewal window. What happens when the underlying document changes category rather than simply expiring is covered in occupational licensing after a change of status, and the timing problem it creates in work authorization and the license renewal cycle.
