What Is an RN Number?

RN stands for Registered Number, which is issued by the Federal Trade Commission (FTC) to U.S.-based businesses involved in the manufacturing, importing, distributing, or selling of textile, wool, or fur products.

However, having an RN number is NOT required. Some companies apply for an RN number voluntarily and use it in place of their business name on product labels.

Why Do Brands Use RN Numbers?

πŸ”Ή Privacy & Branding – Instead of printing a full company name on a clothing label, some businesses opt for an RN number.
πŸ”Ή Regulatory Compliance – While not mandatory, RN numbers simplify labeling for businesses dealing in multiple textile products. For brands preparing to sell in retail stores, understanding barcode compliance is just as important as labeling rules. If you’re unsure how UPC requirements work or whether GS1 codes are necessary, read our guide on UPC codes for retail and GS1 requirements.
πŸ”Ή Industry Standard Practice – Many established clothing brands, manufacturers, and importers register for an RN number to streamline their labeling process.

Want to check an RN number or apply for one? You can do so through the FTC’s official RN lookup tool:

Where Can You Use an RN Number?

Once assigned, an RN number can be used across all product types within the same company. This includes:

βœ” Woven labels – Stitched directly onto garments
βœ” Care & content labels – Printed inside clothing
βœ” Hangtags – Attached externally for branding & compliance
βœ” Heat transfer labels – Tagless label printing

πŸ”Ή One company = One RN number
πŸ”Ή No need for a new RN for every garment, size, or style

If your business produces multiple textile products, a single RN number ensures consistency across all labels.


How to Get an RN Number?

βœ… RN numbers are free
βœ… Issued by the FTC
βœ… Typically assigned within a few days

If your business is involved in the textile industry, obtaining an RN number is a simple process. You can apply directly through the FTC website:
