For a long time I was under the assumption that when you relabeled, you had the option of using the manufacturers RN#. However, after a couple of posts here from others, and a more careful reading of the FTC site, it seems pretty clear you must use your own.I find it interesting that when someone asks about relabeling around here people always seem to recommend that you get your own RN number, yet there are also an equal number of "where did this shirt really come from?" posts where the RN number leads back to the manufacturer, not the store/brand/relabeler..
