An RN textile lookup takes the Registered Identification Number on a textile tag and matches it to the company that registered it in the FTC database. It identifies who registered the number, which often points to the brand or maker. It does not confirm authenticity, age, or value.
You find a shirt with no brand name, just a tag reading "RN 12345." Five minutes of lookup can turn it from a $4 mystery into a listing with a real brand in the title. Or it can tell you the number belongs to a private-label maker and save you from overpricing it. Either result is useful, as long as you know what the lookup can and cannot say.
What an RN number is (and what it isn't)
The FTC assigns RN numbers to US businesses that make, import, distribute, or sell textile, wool, or fur products. The number can stand in for the company name on the required content label. That is why you see tags with fiber content and an RN but no brand.
What it is: a registration tied to a business entity, with a name and usually a location.
What it is not:
- Not a brand guarantee. The registrant may be a parent company, a manufacturer, or a retailer's private label.
- Not an authenticity check. Counterfeiters can copy a real RN. Treat a match as one data point.
- Not a date stamp. Numbers are assigned over time, but a registration can be reused for decades, so you can't read an exact year from it.
- Not a value signal. Knowing the maker does not tell you what the piece will sell for.
How to do an RN textile lookup: 6 steps
This is the workflow we use at intake. It takes about five minutes per item and less once you've done a few.
- Find the right tag. Check the sewn-in content label, usually at the side seam or inside the back neck. Look for "RN" followed by digits. Don't confuse it with a "CA" number (Canadian) or a "WPL" number (older wool products labeling).
- Photograph the tag before anything else. Capture the full label, front and back if it is printed on both sides. [Screenshot placeholder: FlipDesk intake screen with the label photo slot highlighted.]
- Copy the digits exactly. Read the number against the photo, not from memory. Mixing up a 3 and an 8 sends you to the wrong company.
- Search the FTC's RN database. Enter the number in the FTC Registered Identification Number search. The result shows the business name and, in most cases, an address.
- Cross-check the result. Compare the company name against the other tag details: country of origin, fiber content, style, construction. Search the company name along with the garment type to see whether it matches a known label or private brand.
- Log the finding. Record the RN, the registrant name, your confidence level, and the source. [Screenshot placeholder: FlipDesk item record with an RN lookup note field.]
How to read the result
The database returns a name. What that name means depends on the type of registrant. Use this table to decide your next move.
| What you see | What it likely means | What to do |
|---|---|---|
| Name matches a known brand | The brand registered the tag itself | Use the brand in your title once style and construction fit |
| Name is a parent or holding company | Company owns several labels | Search the company's brand list and match on style before naming one |
| Name is a manufacturer | Made for another label or private brand | List by the garment's features, not a brand claim |
| Name is a retailer | Likely a store's private label | Use the retailer name as the brand only if the tag supports it |
| No record found | Typo, a retired registration, or a non-US label | Recheck the digits, then fall back on other tag clues |
A confident brand match is the best outcome. A "manufacturer" result is just as useful, because it stops you from writing a brand into an eBay title that you can't support. Wrong brand claims are a quick path to not-as-described returns.
The limits that cost resellers money
Four failure modes come up most often.
- Naming the wrong brand. A parent company with six labels gives you a name, not a label. Match on style, not just the registrant.
- Treating a match as proof. An RN on a fake tag can still be real. Check the stitching, hardware, fabric, and label font too.
- Assuming it's vintage. An old-looking RN format doesn't date the garment. Use construction details and care-label style as supporting clues.
- Skipping the grade. Knowing the maker tells you nothing about condition. A garment that is Excellent on Fabric Condition and Structural Integrity sells very differently than one that is Fair with pilling and a loose seam, whoever made it.
What to log so the lookup pays off later
The lookup is only worth doing once. If you don't write it down, you'll repeat it, or forget why you titled an item the way you did. Capture these fields on the item record:
- RN number as printed on the tag
- Registrant name from the database
- Your conclusion: brand confirmed, brand likely, maker only, or unknown
- The supporting clues you checked (origin, fiber, construction)
- The tag photo reference
Over a few hundred items this becomes your own reference. When the same RN shows up in the next bag of thrifted clothes, you can reuse the earlier finding in seconds. It also helps with returns. If a buyer disputes a brand claim, you have a record of exactly how you reached it.
Where the lookup fits in your listing workflow
Run the RN lookup at the catalog step, right after sourcing and before measuring and photographing. At that point it can change your decision: a mystery tag that resolves to a known label might justify a full listing, while a generic manufacturer result on a worn piece might send it to a bundle or a donation pile.
Once the maker is settled, the remaining listing work is condition. Grade the garment across the five factors: Fabric Condition, Structural Integrity, Cosmetic Appearance, Functional Elements, and Odor & Cleanliness. Then place it in a tier: NWT, NWOT, Excellent, Very Good, Good, Fair, or Poor. Maker and condition together drive both your title and your price. Neither alone is enough.
Try it on one tagless-brand item
Pick one item in your queue with an RN but no brand. Run the six steps, log the result, and note how long it took. If you want the record kept with the item, add the RN finding in FlipDesk's intake notes and grade the same garment with GradeThread so the maker and the condition sit side by side.
