Number One (1) Code Flag, Nylon Grommets


The International Code of Signals (ICS) flags are used internationally by vessels to communicate messages regarding safety of navigation and related matters.  Individual flags can be hoisted up to display their message to others.

The system was set up by first establishing a standardized alphabet (the letters A through Z and the ten digits), along with a spoken form of each letter.

Single Letter meanings are different and may be made by any method of signaling.  Additionally each letter has its own phonetic spelling.
