If you sell handmade goods, small-batch products, or anything that needs a label, you've probably run into two terms that sound almost the same but mean different things: maker code and manufacturer identification number. Mixing them up can cause labeling errors, compliance headaches, or even rejected shipments. Understanding the difference between maker code versus manufacturer identification number requirements helps you label your products correctly the first time and avoid wasted time and money.

What is a maker code, and how is it different from a manufacturer identification number?

A maker code is a short identifier assigned to or chosen by the person or small business that physically creates a product. It typically appears on product labels, hang tags, or packaging to show who made the item. Think of it as your signature on the product a quick way for buyers, retailers, and regulators to trace the item back to you.

A manufacturer identification number (sometimes called a manufacturer ID or MID) is a more formal code used in regulated industries and supply chains. It's often issued by a government agency, industry body, or standards organization. You'll see manufacturer identification numbers in contexts like textile labeling (where the FTC requires them), electronics, medical devices, and products moving through international trade.

The key difference comes down to who assigns the code and what it's used for. Maker codes are usually self-assigned or assigned by a marketplace. Manufacturer identification numbers follow stricter rules, get registered through official channels, and carry legal weight under specific regulations.

When do you need a maker code instead of a manufacturer identification number?

You need a maker code when you're selling handmade, artisan, or small-batch products through craft fairs, online marketplaces like Etsy or Amazon Handmade, or local retail shops. These platforms and venues often ask sellers to include a maker code on packaging so customers know who created the item. If you're curious about the specific rules that apply, our breakdown of maker code requirements versus manufacturer identification number requirements covers the details.

You need a manufacturer identification number when federal or state regulations require it. For example:

• Textile and apparel products sold in the U.S. must carry a manufacturer identification number under FTC rules (16 CFR Part 303).
• Children's products require tracking labels that include manufacturer info under the Consumer Product Safety Improvement Act (CPSIA).
• Imported goods need a MID for customs documentation.

Some sellers need both. If you make handmade clothing and sell it online, you might need a maker code for your shop branding and a manufacturer identification number for textile labeling compliance. The requirements don't cancel each other out they apply to different aspects of your business.

How do maker code requirements work for product labeling?

Maker code requirements vary depending on where you sell and what you sell. Most craft marketplaces let you create your own code using your business name initials, a short abbreviation, or a number the platform assigns to you. The goal is simple: make sure every product has a clear link back to the person who made it.

For product labeling, you'll typically include your maker code on:

• The product itself (stamped, printed, or sewn in)
• Packaging or hang tags
• A product info card inside the box

What about state-specific maker code rules?

This is where things get more complicated. Some states have their own labeling laws that go beyond federal requirements. For example, California's Proposition 65 requires specific disclosures on certain products. Some states regulate how cosmetics, food items, or candles must be labeled at the state level.

If you sell across state lines which most online sellers do you need to check whether your products meet the rules in every state where you ship. Craft sellers who work from home often overlook this step. Our resource on state-specific maker code requirements for craft sellers walks through what to watch for by state.

What are common mistakes people make with these two codes?

Here are the mistakes that come up most often:

1. Using one code when the other is required. Putting your maker code on a product that legally needs a manufacturer identification number won't satisfy regulators.
2. Skipping registration. Manufacturer identification numbers usually need to be registered with an agency first. You can't just make one up.
3. Forgetting to update codes after a business change. If you change your business name, structure, or location, your old code might no longer be valid.
4. Assuming all platforms use the same system. Etsy, Amazon, eBay, and wholesale buyers may each have different expectations for how your code appears on labels.
5. Ignoring textile labeling rules. If you sew, embroider, or alter clothing, the FTC considers you a manufacturer and the MID requirements apply to you, not just big factories.

How do you get a manufacturer identification number?

The process depends on your industry. For textile products, you register with the FTC. For products regulated by the CPSC, you create an account through their Business Portal. Some industries use GS1 prefixes or codes from other standards bodies. The registration process usually involves providing your business name, address, and product category.

Getting a MID takes time sometimes a few days, sometimes several weeks. Factor this into your product launch timeline so you're not stuck waiting for paperwork when you're ready to ship.

Can a small seller use the same code system as a large manufacturer?

Yes, but it depends on the system. GS1 barcodes, for example, are available to businesses of any size you just pay a membership fee. FTC textile registrations are free. The system doesn't care how big your operation is; it cares whether you followed the registration process.

For maker codes, the barrier is much lower. Most craft marketplaces and local selling venues want a simple, unique identifier. There's usually no fee and no formal registration beyond creating a seller account.

What should you do right now to get your labeling in order?

Start with a quick audit of your current products and labels. Then work through this checklist:

• Identify which regulations apply to your product type. Textiles, cosmetics, children's products, and food items all have different rules.
• Check whether your selling platform requires a maker code and how they want it formatted.
• Determine if you need a registered manufacturer identification number based on federal or state law.
• Register for a MID if required don't wait until you're already selling.
• Review your product labels to make sure the right code appears in the right place.
• If you sell in multiple states, verify that your labels meet the strictest state requirements you ship to.
• Keep a record of all your codes, registration dates, and renewal deadlines in one place.

One more tip: if you use custom fonts on your labels or packaging, make sure the font you choose has a commercial-use license. Free personal-use fonts aren't always cleared for product labeling. You can browse licensed options at places like Montserrat or similar font libraries.

Getting your maker code and manufacturer identification number sorted out early saves you from relabeling costs, compliance warnings, and confused customers down the road. Do it once, do it right, and you won't have to think about it again until something changes in your business.
