Route Codes

Hello, I am new here and unfamiliar with the codes used for the route that a plane is taking to get from point a to point b. Is there a FAQ or some location on this site that would be useful in decyphering the codes used. I would appreciate any input on this subject, and I do apologize if I am posting in the wrong location. Thanks for FAA mumbo jumbo for navigation aids for fixs

Entries that begin with J are jet airways
Entries that begin with V are low altitude airways.


Thanks so much lieberma, I’m sure this will help
