The Definitive 2020 stamps, like others before it, uses a colour coding to identify which country you need to send your post to and features Her Majesty’s Government of Gibraltar crest as the central design feature.
A definitive stamp is a postage stamp that is part of the regular issue of a country’s stamps, available for sale by the post office for an extended period of time and designed to serve the everyday postal needs of the country. The term is used in contrast to a commemorative stamp, a stamp issued to honour a person or mark a special event available only for a limited time.
Commonly, a definitive issue or series includes stamps in a range of denominations sufficient to cover current postal rates. Additional stamps in a Definitive series may be produced as needed by changes in postal rates but some values may be permanently available, regardless of prevailing rates.
Since postal administrations know that many stamp collectors want to own every stamp of a definitive series, collectors organizations have recommended that administrations only bring out new definitive issues no more often than every five years and most administrations of the world follow this policy. An exception would be the death of a monarch, or other prominent leader, necessitating a new definitive series for the new ruler. Sometimes merely the portrait is changed, and the outer design (known as the frame) remains the same throughout several issues.
