Registered identification number
number issued by the Federal Trade Commission to a business
A registered identification number (or RN) is a number issued by the Federal Trade Commission, upon request, to a business residing in the United States that is engaged in the manufacture, importation, 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 their products.
Formerly the Federal Trade Commission issued Wool Products Labeling (WPL) numbers as identification numbers to companies manufacturing wool products. Although new WPL numbers are no longer issued, many are still in use in a similar way as RN numbers.
This brief starts where responsible research should: with the source description of “Registered identification number” as number issued by the Federal Trade Commission to a business. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as number issued by the Federal Trade Commission to a business. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Oct 20, 2025. The linked authority identifier is Q7309384. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
