AFTN Station Address Format
An AFTN address is an eight-letter-group composed of a four-letter ICAO Location Indicator plus a three-letter-group identifying an organization or service addressed and an additional letter. The additional letter represents a department, division or process within the organization/function addressed. The letter X is used to complete the address when an explicit identification of the department, division or process is not required. For instance: LEBBYNY.
The four-letter Location Indicators are listed in ICAO Doc 7910 — Location Indicators. The three-letter designators are listed in ICAO Doc 8585 — Designators for Aircraft Operating Agencies, Aeronautical Authorities and Services.
Every location (airport or other facility) with a connection to the Aeronautical Fixed Service is assigned a unique four letter code (the aeronautical location indicator) by ICAO. The first letter or two letters indicate the country and the remaining two or three letters the specific location. For instance the letter K is the first letter of the four letter ICAO address location within the continental United States. The first letter for a Canadian aerodrome, or airport address, begins with the letter C. Southern Europe codes begin with L, and specifically codes in Spain with LE. For example New York's John F. Kennedy airport is KJFK while Goose Bay Canada's airport is identified as CYYR and Bilbao in Spain as LEBB.
Some irregular four-letter codes, not assigned by ICAO, do exist and appear usually in meteorological reports.
Examples for some common three-letter-groups used in AFTN addresses in order to identify an organization or service:
| Facility code | refers to |
|---|---|
| YFYX | "AFTN Office" |
| ZTZX | "Control tower" |
| ZPZX | "ATS Reporting Office" |
| ZQZX | "Area Control Center" |
| YNYX | "Notam Office" |
| YDYX | "Airport Manager" |
| YZYX | "Met Data Bank" |
| YMYX | "Local Met Office" |
| ZRZA | "Radar Approach" |
- Therefore the address LEBBYNYX indicates the NOTAM office of Bilbao Airport, Spain.

Famous quotes containing the words station and/or address:
“When, in the course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume the powers of the earth, the separate and equal station to which the laws of nature and of nature’s God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.”
—Thomas Jefferson (1743–1826)
“In the mythus a superhuman intelligence uses the unconscious thoughts and dreams of men as its hieroglyphics to address men unborn.”
—Henry David Thoreau (1817–1862)
