Scott is a company that publishes a listing or catalog of all of the issued stamps in the world. They assign each stamp a number. A normal stamp used for postage on envelopes or cards has a plain number, such as US #1257 or GB #579. There are letter prefixes used that help identify other types of stamps, such as a C for airmail as in US #C47, or J for postage due Belgium #J151.
These numbers allow collectors to know that they are talking about the same stamp and are often used in auction catalogs and in files.
Scott is a company that has been producing catalogs of stamps in the United States for over 100 years. They assign a number to each stamp issued by every country. That number, with the country name, uniquely identifies that specific stamp to a collector or dealer.
