RN Numbers Explained: Do You Need One?

What an RN actually is

A Registered Identification Number is a unique number the FTC issues to a US business involved in manufacturing, importing, distributing or selling textile, wool or fur products. On a garment label it can be used in place of the company name to satisfy the “identity of the responsible party” requirement.

Is it required?

No. Your full registered business name is always a valid alternative, and plenty of brands label that way. An RN is a convenience, not an obligation.

Why brands get one anyway

• The legal entity name is often not the brand name. “Smith Holdings LLC” on the inside of every garment is not a great look; an RN avoids it.
• It is compact. Label space is genuinely tight once you have fibre content, origin and care instructions on the same tag.
• It is free and the application is short.
• Some retailers and marketplaces ask for one, even though the law does not.

What an RN is not

• It is not a trademark or any form of brand protection.
• It is not a licence or a certification — it does not say anything about your product.
• It does not replace fibre content, country of origin or care instructions. It only covers the “who is responsible” element.
• It is not transferable. If the legal entity changes, the RN does not travel with the brand.

One practical caution

RN numbers are publicly searchable, and the lookup returns the registered business. Anyone can take the RN from a label and find out who actually makes or imports a product — which is useful to you when researching competitors, and equally available to people researching you.

If you do not have one yet

Use your full registered business name on the label. It is compliant, it is immediate, and you can switch to an RN at your next label order without re-running anything else.

This is a working summary rather than legal advice — confirm the current requirements before you commit to a label.
