Label or coupon or tab in philately is a part of sheet of stamps separated from them with perforation (or narrow white margin in imperforate stamps). It cannot be used for postage because it does not have face value and any indication of a postal administration that issued such stamps with labels. The notion of label should not be messed up with the term "gutter" or with a margin of a stamp sheet.
