# RN Clothing Lookup: How to Search an RN and What It Tells You

_By GradeThread Team · Published October 10, 2026_

> An RN clothing lookup names the company that registered a tag, not the year it was made. Here is how to run one, read it, and use it when you grade.

An RN clothing lookup tells you which company registered the Registered Identification Number on a garment's tag. It does not tell you the year the piece was made, and it does not prove authenticity. Use it as one clue about who stood behind the label, then grade the garment on its own condition.

Here is the scenario we see often. A reseller finds a boxy 1990s-looking jacket with an RN on the tag, searches it, and lists it as 'vintage 1992' because the registrant looks old. The buyer opens a return: the tag is from a later reissue. The RN was never a date stamp. This guide covers how to search one, how to read the result, and where it fits in a listing.

## What an RN number is

The Federal Trade Commission issues RN numbers to US businesses that make, import, distribute, or sell textile products. The number appears on the content tag, usually near the fiber percentages and care instructions. Under the Textile Act, a label can carry either the company name or its RN. The RN is a shortcut that points to the registrant on file.

Three facts shape everything else:

- **It identifies a company, not a garment.** One RN covers every product that company labels.
- **It stays with the registrant.** The same RN can appear on tags across many years.
- **Registrants change.** Businesses merge, rename, and sell the registration, so the current record may not match the brand on the tag.

## How to run an RN clothing lookup

The process takes about a minute per tag. Follow these steps in order:

1. Find the content tag and locate the number printed as 'RN' followed by digits (often five or six). Some tags use 'CA' numbers instead; those are Canadian identifiers and use a separate database.
2. Photograph the tag so the digits are readable and keep that photo for your listing records.
3. Open the FTC's RN database search and enter the digits only, with no spaces or letters.
4. Read the returned record: company name, business type, and address on file.
5. Compare the registrant to the brand on the main label. Note whether they match, differ, or point to a parent company or importer.
6. Write down the result in your listing notes as 'registrant' information, not as a production year.

If the search returns nothing, check for a typo, then try the digits as printed on a second tag if the garment has one. Some older registrations are inactive and may not display the way a current record does.

## How to read the result

The record is a starting point. Here is what each outcome usually means and how to treat it.

| Lookup result | What it suggests | What to do |
| --- | --- | --- |
| Registrant matches the brand on the label | Consistent with a genuine in-house label | Note it, then continue with the rest of your checks |
| Registrant is a parent company or importer | Common for licensed or imported lines | Research the corporate relationship before you describe the piece |
| Registrant is a different, unrelated company | Could be a private label, a licensee, or a mismatch worth investigating | Check stitching, hardware, and label details before listing |
| No record found | Typo, inactive registration, or a non-US tag | Re-check digits; do not draw a conclusion from silence |

A mismatch is a flag, not a verdict. Plenty of genuine garments carry a manufacturer's RN rather than the brand's own. For the full checklist beyond tags, see our guide to authenticity checks.

## What an RN lookup cannot tell you

Resellers overread this tool, so be precise about its limits.

- **Age.** Because the registration persists, a record cannot date a specific garment. Use it alongside the tag format, fiber disclosure style, and construction details.
- **Authenticity.** A real RN can be copied onto a counterfeit tag. A match is supportive, never proof.
- **Condition.** Nothing in the record says how the garment has aged, been worn, or been repaired.
- **Country of origin.** Origin labeling is separate from the RN.

If you state a decade in a listing, support it with several signals, and say 'circa' when you are inferring. A wrong date is a fast route to a 'not as described' case.

## Where the lookup fits in your grading workflow

Identity and condition are two different calls. The RN helps with the first. The second is graded on a 1.0 to 10.0 scale, across five factors: Fabric Condition, Structural Integrity, Cosmetic Appearance, Functional Elements, and Odor & Cleanliness.

A practical order of operations:

1. Run the RN and record the registrant.
2. Inspect the tag itself. Is it crisp or frayed? Is it legible? A cut or faded tag affects Cosmetic Appearance and may limit what you can verify.
3. Grade each factor on the garment. Check seams and stress points for Structural Integrity, zippers and buttons for Functional Elements, and do a smell test for Odor & Cleanliness.
4. Place the piece in a tier: NWT, NWOT, Excellent, Very Good, Good, Fair, or Poor.

Tags matter at the top of the scale. NWT means the original tags are attached, so a missing or removed tag means the item cannot be NWT, whatever the registrant says. A pristine unworn piece with the tag removed fits NWOT. A great RN result on a Fair garment still sells as Fair. Price follows the grade, and the lookup is context, not leverage.

## Using the result in your listing

State what you verified and keep claims modest. On eBay, put the brand and size in item specifics and describe tag details in the description. On Poshmark and Mercari, the same rule applies: say 'RN registered to [company]' if it is useful, and avoid implying a manufacturing date.

Add a clear photo of the content tag and one of the main label. Buyers who collect a brand often search the RN themselves, and a legible tag photo answers that question before they message you. A clean tag photo and a consistent condition grade together cut the ambiguity that leads to disputes.

We do not guarantee that any lookup, grade, or listing detail will prevent a return. What it does is remove the easy arguments, which are the ones that cost you most.

## Grade the garment, not just the tag

If you have a piece on your table with an RN you have just searched, finish the job. Grade one garment with GradeThread and see the five-factor condition report, the tier, and a certificate buyers can verify. It takes a few photos, and it shows you where your own adjective would have drifted from the standard.
