Where to Find Maker Code on Clothing Label

Finding a maker code on a clothing label might seem like a small detail, but it can tell you exactly who manufactured a garment, where it was made, and whether it meets quality or compliance standards. Whether you're reselling vintage clothing, filing a product complaint, or trying to verify authenticity before a purchase, knowing where to look on the label saves time and guesswork. The problem is that maker codes aren't always in the same spot, and they can be easy to miss if you don't know what you're looking for.

What exactly is a maker code on a clothing label?

A maker code is a short alphanumeric identifier printed or woven into a garment's label. It tells you which company or factory produced the item. You might also hear it called a manufacturer ID code, factory code, or RN number (in the United States, the FTC issues RN numbers to registered businesses in the textile industry).

This code is not the same as a style number, size, or care instruction. It specifically points to the maker the company responsible for manufacturing or importing the garment.

If you've ever looked at how manufacturer ID codes work on electronics, the concept is similar. The code acts as a fingerprint for the producing company.

Where on the clothing label should you look for the maker code?

Most clothing labels are sewn into specific locations. Here's where to check first:

Side seam label: This is the most common location. Look at the inner left side seam near the waist or hip area. The maker code is usually printed near the brand name or below the fabric composition details.
Back neck label: On tops, dresses, and jackets, the maker code often appears on the back neckline tag, either printed directly or on a separate small tag stitched next to it.
Waistband label: For pants, shorts, and skirts, check inside the waistband. The code may sit on the main label or on a secondary compliance tag nearby.
Secondary or hang tag: Some brands print the maker code on a hang tag attached with plastic or string rather than on the sewn-in label.
Inner pocket label: On outerwear and suits, the maker code sometimes appears inside an interior pocket.

A more detailed breakdown of label positions is covered in this guide on finding maker codes on clothing labels.

What does the maker code actually look like?

Maker codes vary depending on the country and regulatory body. Here are the most common formats you'll encounter:

RN number (US): Looks like "RN 12345" a five-to-six-digit number preceded by "RN." The FTC assigns these.
CA number (Canada): Appears as "CA 12345" and is issued by the Competition Bureau of Canada.
WPL number (US, older): Similar to RN numbers but issued under an earlier labeling act. Format: "WPL 12345."
Factory code or internal maker code: Some brands use proprietary alphanumeric codes, like "MK-0042" or "FAC 88," that aren't publicly searchable but can be referenced when contacting the brand directly.
Registered trademark symbols: You may see a brand name followed by ™ or ® near the maker code, which helps identify the registered business entity.

Why would you need to find the maker code on a garment?

There are several practical reasons people search for maker codes:

Product safety complaints: If a garment causes a skin reaction or has a defect, consumer protection agencies require the maker code to trace the manufacturer.
Resale and authentication: Vintage resellers use maker codes to verify that a piece is genuinely from a specific brand or era.
Regulatory compliance: Importers and retailers need maker codes to meet textile labeling laws in the US, EU, and Canada.
Brand research: If you find a garment with no visible brand name, the maker code can help you figure out who produced it.
Sustainability tracking: Some consumers trace maker codes to learn about factory conditions or a brand's supply chain transparency.

The process is quite similar when you read manufacturer codes on appliances, where the identifier serves the same tracing and compliance purpose.

What are common mistakes people make when looking for maker codes?

A few things trip people up regularly:

Confusing the care label with the maker label: The care tag lists washing instructions and fabric content. The maker code might be on a completely separate tag.
Assuming all brands use RN numbers: Not every garment carries an RN number. International brands may use their country's equivalent, or use internal codes instead.
Looking only on printed tags: Some maker codes are woven into the label fabric rather than printed. These can be harder to see in low light.
Ignoring secondary tags: The code might not be on the main label at all. Check every tag attached to the garment, including compliance stickers.
Throwing away hang tags: If the maker code is on a removable hang tag, cutting it off means losing that information permanently.

How do you find the maker code if the label is faded or damaged?

Older garments or secondhand clothing often have worn labels. Here's what you can do:

Use a bright flashlight or your phone's flashlight to illuminate the tag faint print often becomes readable under direct light.
Take a photo of the label and increase the contrast or use a scanning app that enhances text visibility.
Look for a secondary label in a different location on the garment. Many items have multiple tags, and one may be in better condition.
Search the brand name plus "RN number" online. Public FTC databases let you look up RN numbers by company name, which can help confirm the maker even if the code is partially visible.
Contact the brand's customer service with a photo of the garment. They can often identify the maker from other details like style number or production year.

Can you look up a maker code online?

Yes, if the garment has an RN or CA number, you can search it in public databases:

FTC RN Search (US): The Federal Trade Commission maintains a searchable database at ftc.gov where you can enter an RN number to find the registered company.
Canadian CA number lookup: The Competition Bureau of Canada provides similar lookup tools for CA numbers.

For proprietary maker codes that brands use internally, there's no public database. You'll need to reach out to the brand directly.

Quick checklist before you search your clothing label

Check the side seam label first it's the most common location for maker codes
Look at every tag on the garment, not just the main brand label
Know the difference between care instructions, style numbers, and maker codes
Use a flashlight if the label looks faded or hard to read
If you find an RN or CA number, look it up in the FTC or Canadian database to confirm the manufacturer
Take a photo of the label before removing any hang tags you might need the information later

Next time you pick up a garment and need to know who made it, start with the side seam, check every tag, and remember that the maker code is your most reliable way to trace the source. Keep your phone handy to photograph labels before they wear out future you will thank you.
