I was looking thru the FCC database and came across listings for "Target
Area".

One said "10-13"

The International Telecommunications Union (ITU) has divided the world
into geographic zones for various reasons.

The "Target Areas" of U.S. international broadcasters are ITU zones.

Zones 10-13 are Mexico, Central America, the Caribbean, and northern
South America.
