An RN number search means looking up the five- to seven-digit Registered Identification Number on a clothing tag in the FTC's RN database to see which U.S. business registered it. It identifies the company, not the garment's brand history, authenticity, or value.
You've got a tag reading "RN 12345" and no brand name. Or a vintage piece with a half-washed-out label. Five minutes of searching can turn an unlisted mystery item into a titled, specific listing. Here's how to run the search, what to do with the result, and where it stops being useful.
What an RN number is (and what it isn't)
The FTC issues RNs to U.S. businesses that manufacture, import, distribute, or sell textile, wool, or fur products. A company can use the RN on a label instead of printing its name. Think of it as a registration ID for a business.
What it is:
- A pointer to a registered company name, and often a business address.
- A useful clue for dating or placing a piece, since the company's history tells you something.
- A way to identify private-label and store-brand garments with no visible brand.
What it isn't:
- Proof the garment is authentic. Counterfeiters can copy an RN or use a real one that isn't theirs.
- A price guide. The registrant may be a department store, a holding company, or a manufacturer that made clothes for dozens of brands.
- A guarantee the number is current. Companies merge, rename, and stop operating, and some tags carry numbers for businesses that no longer exist.
- Available on every garment. Items made outside the U.S. may carry a different identifier, such as a CA number (Canada) or none at all.
How to run an RN number search: 5 steps
This is the workflow we use at the sorting table. It takes about five minutes per item once you've done it a few times.
- Find the tag and read the number exactly. Look on the sewn-in content label, usually at the neck, side seam, or waistband. The RN appears as "RN" followed by digits. Photograph it in good light first. Faded numbers are easy to misread, and 3 versus 8 or 1 versus 7 errors send you to the wrong company.
- Open the FTC's RN database. Search the FTC's Registered Identification Number lookup. Choose the option to search by RN number rather than by company name.
- Enter only the digits. Skip the "RN" prefix. If nothing returns, try the number again with one adjacent digit changed only if the tag is worn enough to justify doubt, then re-verify against your photo.
- Read the registrant record. Note the legal business name, location, and status where shown. Don't treat the first line as the brand. Many registrants are parent companies. Search the company name separately to see which labels it has used.
- Cross-check against the rest of the garment. Compare the registrant to the style, fabric, country of origin, care label format, and any other branding. If they conflict, flag the item. A mismatch isn't proof of anything, but it means you need another source before you name the brand in a title.

What to do when the RN search comes up empty
Some searches return nothing. That's common, and it's not a dead end. Work through these in order:
- Recheck the digits. Misreads are the most common cause.
- Try a company-name search if the tag has a partial name or a city.
- Check other labels. Hang tags, size labels, and interior stamps sometimes carry the brand even when the content tag doesn't.
- Look at the construction. Union labels, stitching style, zipper stamps, and button backs can point to an era or maker.
- Search similar listings using fabric content, cut, and tag layout, and compare sold results rather than active ones.
If you still can't identify it, list it by what you can prove: garment type, fabric content, measurements, and condition. A specific, honest, brandless title beats a guessed brand. Guessing wrong invites a not-as-described case.
How to use the result in your eBay listing
The RN gives you a lead. What you do with it depends on how well it matches the garment.
| Search result | What it supports | What it doesn't support |
|---|---|---|
| Registrant is a known brand's company, and the garment style matches | Using the brand in the title with moderate confidence; filling the Brand item specific | Claiming authenticity or a specific era without more evidence |
| Registrant is a retailer or department store | Identifying a store label; noting "private label" in the description | Naming a designer or manufacturer brand |
| Registrant is a manufacturer with many clients | Narrowing the era and region; using it as a research lead | Putting any single brand in the title |
| No result or conflicting details | Listing by garment type, fabric, and measurements | Any brand claim |
Brand is an eBay item specific, and blank or wrong specifics hurt you twice: buyers who filter by brand won't see the listing, and a wrong brand sets up a dispute. Only enter a brand you can support with more than the RN alone.
Log it so you don't redo the search
The worst time to rerun an RN search is three weeks later, when you're relisting and the tag photo is buried. Record these on every item that needed the search:
- The RN as it appears on the tag.
- The registrant name from the FTC record.
- Your confidence level: confirmed by other labels, likely, or unverified.
- The date and source of the search.
- Any conflicts you noticed.
In a spreadsheet, that's five more columns. In FlipDesk, it belongs in the item's intake record next to the tag photo, so the evidence stays attached to the SKU through listing, sale, and any return.
The time math matters at volume. Say an RN search plus logging adds four minutes. On the 10 items per 100 sourced that lack a visible brand, that's about 40 minutes. If it turns even a few of those from "unbranded blouse" into a correctly specified listing, it earns its time. If it doesn't, you've spent four minutes to rule it out and move on.
Where condition fits in
Identifying the maker answers "what is this?" It doesn't answer "what shape is it in?" Two garments from the same registrant can sell at very different prices depending on grade. A GradeThread grade looks at Fabric Condition, Structural Integrity, Cosmetic Appearance, Functional Elements, and Odor & Cleanliness, and places the piece in a tier: NWT, NWOT, Excellent, Very Good, Good, Fair, or Poor.
Do both before you list. A confirmed maker plus a clear condition tier gives buyers two things to trust. It also gives you a record to point to if a buyer opens a return claiming the item wasn't as described. Tag evidence and condition evidence are both line items in your returns story.
Try it on one item
Pick one tagless-looking piece from your current pile and run the five steps. Log the RN, the registrant, and your confidence. Then grade the garment. If you want the record kept with the item instead of in a loose note, add the RN to that item's intake record in FlipDesk and see whether it saves you a search the next time.
