Three-letter and telephony designators are assigned on a worldwide basis to an aircraft operating or servicing company for commercial domestic/international operations.

If you are an aircraft operating agency, aeronautical authority or service provider associated with international aviation and you already have a three-letter and a telephony designator intended for use on the international aeronautical telecommunications services, and need an additional copy of this confirmation, you need to request it through your focal point after purchasing the corresponding PIN. Please purchase this PIN and copy/paste it in the Confirmation Letter format that you will find in the 3LD website http://www.icao.int/3LD under Industry.
