RN# USA

RN=Registered identification Number

A registered identification number or RN is a number issued by the Federal Trade Commission, upon request, to a business residing in the U.S. that is engaged in the manufacture, importing, distribution, or sale of textile, wool, or fur products. Such businesses are not required to have RNs. They may, however, use the RN in place of a name on the label or tag that is required to be affixed to these products.
