Vessels sailing under the Peru Country Flag are required to have on board this flag as part of flag state requirements that derive from maritime regulations in the International Code of Signals and the International Safety Management (ISM) Code. These codes are published by the International Maritime Organization (IMO) as an ongoing effort to reinforce maritime safety procedures and communications to the international maritime community. Fleet management companies and ship owners are responsible to ensure that each vessel in their respective fleets have the appropriate flag signage onboard to be in compliance. This flag is used to identify the flag state a vessel is sailing under and to communicate with other vessels under the provisions of the International Code of Signals.
The Peru Country Flag may be identified by it's three, equally proportioned vertical stripes. These stripes are colored red, white and red as viewed from the hoist, or left side to the fly, or right side. The Peru Country Flag was officially adopted in 1825, making it one of the most historic flags in the world. It is designated to hold a proportional ratio of 2:3, height to length, respectively. The use of the color red holds meaning for the people of Peru, representing the blood that was sacrificed in defense of the country and to attain independence from Spain in 1821. The white color is meant to symbolize the hope for peace and the freedom associated with independence. The original design of the Peruvian flag included four stripes that were divided diagonally, but was quickly exchanged for the modern standard. Peru also possesses a State Flag. That National Symbol appears similar to the Peru Country Flag in that it is represented by three similarly colored stripes, but is interrupted at the center with the National Coat Of Arms.
