What is an RN number on clothing? The FTC code that stands in for a company name

An RN number on clothing is a Registered Identification Number, a code the Federal Trade Commission issues to U.S. businesses so they can put a number on a label instead of their full company name. If you see "RN 12345" on a tag, you can look up which business holds it for free. It tells you who is responsible for the label. It does not tell you where the garment was made or whether it is any good.

What the FTC says an RN is

The rule sits inside the federal labeling laws for textiles, wool and fur. The FTC's guidance says an RN "may be issued to any firm in the U.S. that manufactures, imports, markets, distributes or otherwise handles textile, wool or fur products." It adds that "RNs are not issued to businesses outside of the U.S."

The point is convenience. The FTC's page says "You may use an RN instead of a name to satisfy the labeling requirement." A company name can be long, and tags are small. The prefix "RN" or "WPL" is part of the number and must come before the digits.

An RN is optional. The FTC states plainly that "An RN is not required in order to do business in the U.S." A brand that prefers to print its full business name can do so. The name must be the full name the company does business under, not simply a trademark or brand, unless that is the business name.

What else must be on the tag

An RN solves only one of three requirements. According to the FTC, textile labels must identify the fiber content, the country of origin, and either the company name or the RN of the manufacturer, importer or other firm handling the product. Fibers go in descending order of predominance by weight, and imported products must identify the country where they were processed or manufactured.

So three lines answer three questions. The fiber line says what the garment is made of. The country line says where it was processed or manufactured. The RN, or the name, says which U.S. business stands behind the label. They are separate facts and one never substitutes for another. For more on the fiber line, see our explainer on clothing fiber content labels, and for the country line our piece on clothing country of origin rules.

How to look up an RN

The FTC runs a public database. Its February 2025 privacy impact assessment says businesses, consumers, staff and law enforcement can search the online RN database to find the owners of RNs. The FTC's database page directs searches to the RN database at rn.ftc.gov and says the new RN system is live. Existing RNs remain valid without a new login account.

What you get back is largely ordinary business information. The assessment says each record has fewer than two dozen data fields, including the legal name of the business, the names under which it does business, its legal form, and its U.S. physical and mailing addresses. That is enough to find a company and check whether the name on the label matches the business that holds the number.

How common are RNs?

Common enough that the FTC runs a whole program for them. The same assessment says the system "contains data on tens of thousands of RN numbers," and that "in recent years, the FTC has issued approximately 3,000 RNs per year." Those are the FTC's own descriptions, and the agency gives no exact total in the document we read. We did not find a published count of how many RNs are currently active.

Getting one costs nothing. The FTC's database page says businesses can apply for an RN, or update an existing one, "free of charge." There is no fee to pay the FTC for the number.

What an RN does not prove

An RN is an identification number, not a seal of approval. Three limits matter.

First, it says nothing about origin. A U.S. importer can hold an RN for a garment sewn in another country, and the country line carries that fact.

Second, it can go stale. The FTC says it urges companies to keep their information current, and it may cancel an RN for failing to do so or for obtaining or using it improperly. A record you find may not describe the business as it stands today.

Third, it is not transferable. The FTC says "RNs and WPLs are not transferable or assignable." If a brand is sold, the number does not simply move with the logo. That matters when you try to track a label through a change of ownership.

It also does not apply abroad. The FTC says only U.S. firms qualify, so a tag from a company outside the country will show its name instead. Absence of an RN is therefore normal and says nothing bad about a label.

When the RN helps

The practical use is detective work. A tag from a seller you have never heard of, a returned item with no brand, a gift with a faded label: the RN lets you identify the U.S. business that stands behind it. If the number returns nothing, or returns a business that does not match the label, that is a reason to ask questions. It is not proof of wrongdoing, because records can go stale and a number can be cancelled.

Our take

Treat the RN as a free directory entry. It is useful, public and easy to check, and it is one of the few places on a tag where a real, named business is attached to the product. It is not a quality mark, a sustainability claim or an origin statement, and brands do not earn credibility by printing one. Read it together with the fiber and country lines, and look it up when a label leaves you guessing.
