It's free to get your own RN# and they e-mail it to you within a day or two. You can apply here. In addition to fiber content, origin and RN#, you also need care instructions on the label.Hello! I have a question about relabeling and RN#s When relabeling does the original RN# go onto the new label, along with the material, "my Brand" name, and origin? Or does my RN# go on it. Do I need my own RN if I am not making the shirt? Just adding graphics and relabeling.
