RN stands for ‘registered number’ and it’s a number issued by the Federal Trade Commission if requested. They are for businesses residing in the U.S. that are engaged in the manufacture, importing, distribution, or sale of textiles, wool, or fur products. Here’s the important part – 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.
RN numbers can be incorporated into all types of clothing labels like woven labels, care/content printed labels, hangtags and Tagless heat transfers. You can use the same RN number for all different items that you may produce. You don’t need a new RN for every style, color, size of your garments. RN numbers are free and only take a few days to have it assigned.
