Issued by France in 1972, this modern graphic stamp commemorates the nationwide introduction and promotion of the Code Postal system. The dynamic design symbolically shows automated mail sorting through numbered routing dots entering an envelope, reflecting postal modernization. During the early 1970s, France expanded mechanized mail processing to improve delivery efficiency. The bold red background and minimalist artwork represent the transition toward computerized postal operations. A notable thematic piece for collectors of communications, postal history, and technology-related issues.
