Definitive Stamps are issued by Postal Department for regular consumer mail usage. They are sold for prolonged period of time unlike Commemorative and other special stamps offered for a limited period of time and are frequently replaced by a new issue or series. The term ‘Definitive Stamp’ is used in contrast with a ‘Commemorative Stamp’ issued to honor a person or mark a special event and available only for a limited time. It is observed that commemorative stamps are issued for a special anniversary or to celebrate an event, achievement, famous person or any other theme. As against this, definitive stamps are issued regularly by all small or big Post offices over the counter for daily use.Unlike Commemorative stamps which have three to six different value denominations, a definitive issue or series includes stamps in a range of denominations sufficient to cover many or all postal rates. The underlining concept is that values should be sufficient to make up all possible charges using as few stamps as possible. The range of values varies by time and postal needs, but the focus is on all pervading coverage.Since definitive series are issued over a period of time and are reprinted to meet postal demand, they often contain more variation than is typically found in stamps that have a single print run. We find FDCs of all or many of these types duly cancelled on first day of issue of Definitive Stamps.
