RN Clothing Lookup: How to Identify a Maker From the Tag in 5 Steps

An RN clothing lookup means entering the RN number from a garment's tag into the FTC's Registered Identification Number database to see which company registered it. It identifies a business, not a brand's current label, a year, or a value, so treat it as one clue and log it.

Say you're at a thrift store with a jacket whose tag has no brand name, just a line reading "RN 12345" and a fiber content list. You have 30 seconds before the cart moves on. A lookup takes about one minute on a phone. A wrong guess costs you $8 and a shelf slot for 90 days. This guide covers the workflow, where it breaks, and how to record the result so the time pays off at listing.

What an RN clothing lookup actually returns

RN stands for Registered Identification Number. The FTC issues it to US businesses that make, import, distribute, or sell textile products, so those businesses can put an ID on the label instead of a full company name. A lookup returns, typically:

• The registered business name
• A business type, such as manufacturer or importer
• An address, when the record has one
• Sometimes other contact details

It does not return a brand story, a production year, a retail price, or an authenticity verdict. A company can also register one RN and sell under several labels, or sell its private-label goods under a name you've never heard of.

The 5-step RN clothing lookup workflow

Run this in order. Each step is one action.

1. Find the RN number on the tag. Check the sewn-in content label, usually at the side seam or behind the neck label. It's printed as "RN" followed by 4 to 6 digits. Don't confuse it with a CA number, which is a Canadian identifier, or with a style or lot number.
2. Photograph the full label. Capture the RN, fiber content, country of origin, and care text in one shot. This is your record if the tag gets cut out or the number is faint later.
3. Search the number in the FTC RN database. Enter only the digits. Read the registered name and business type. If nothing returns, recheck the digits before assuming the number is invalid.
4. Cross-check the result against the garment. Does the company name connect to a brand you can find on the item, in the stitching, on buttons, or in the care label? Search the company name together with the garment type to see what labels it sold under. Treat a match as support, not proof.
5. Log the result with the item. Record the RN, the registered name, the date you checked, and a confidence note: confirmed, probable, or unknown. Then use it in your title and item specifics only where you're confident.

What the lookup can't tell you

The result has real blind spots. Knowing them keeps you from writing a listing you'll regret.

Other limits matter too. Companies merge, get acquired, or close, and a record can reflect an old owner. An RN can be reused by a business across many product lines. And some garments, especially imports and older pieces, carry no RN at all.

How to use the result in a listing

Once you have a registered name, you have three practical uses.

• Search terms for comps. Search the company name plus garment type in eBay's sold listings. If a registered company sold under a known label, you may find matching tags and styles in past sales.
• Item specifics. Fill Brand only when the evidence supports it. If you only know the manufacturer, say so in the description rather than claiming a brand. A wrong Brand specific sets up a not-as-described claim.
• Title keywords. A confirmed brand belongs near the front of the title. A probable one belongs in the description with the wording "tag reads RN 12345." Buyers who search by RN will find it.

Then grade the garment on its own merits. Brand identification and condition are separate questions. A maker you've identified still needs a condition tier, whether NWT, NWOT, Excellent, Very Good, Good, Fair, or Poor, based on Fabric Condition, Structural Integrity, Cosmetic Appearance, Functional Elements, and Odor & Cleanliness. A good identification on a Poor garment is still a Poor garment.

The math: is the lookup worth the time?

Here's an example, not a benchmark. Suppose an unlabeled wool blazer costs you $9. Without a brand, you list it generically and it sells for around $22 after 60 days. With a brand identified in two minutes and a better title, assume it sells for $48 in 30 days.

Two minutes of lookup against a $22.56 gap is a strong return. But the example is a best case. Plenty of tags will resolve to a company with no brand value, and then the lookup earned you a log entry and a decision to pass or price low. That's still useful: it stops you from overpaying for a mystery piece.

Log it so you only do it once

The most common waste is repeating the same lookup because nobody recorded it. Keep these fields with each item:

• RN number
• Registered business name
• Date checked
• Confidence: confirmed, probable, unknown
• Tag photo filename tied to the SKU

When you source a second piece with the same RN, you'll already know the maker and can compare your earlier sold prices. That compounds across 500 items. A spreadsheet works at low volume. Past a few hundred items, searching your own history by RN is where a structured inventory record pays off.

Try it on one item

Pick one unlabeled piece in your current stock, run the five steps, and time yourself. If the result changes your title or your price, add the RN field to your intake routine. FlipDesk's catalog step keeps the RN, tag photo, and confidence note attached to the SKU, so the lookup is done once and reused when you draft the listing.
