Geographic components list

Can anyone point me to a recent list of geographic component codes? I can't seem to locate one anywhere on the Bureau's website, FTP, or docs.

I have one from about 2010 but would like to update it if possible.

It looks possible to extract it from the geos file (e.g. Geos20235YR.txt).

ACSSF|US|010|00|1||||||||||||||||||||||.|.|||||||||||||0100000US|United States|||

ACSSF|US|010|90|1||||||||||||||||||||||.|.|||||||||||||0100090US|United States -- American Indian Reservation and Trust Land -- State|||

ACSSF|US|010|94|1||||||||||||||||||||||.|.|||||||||||||0100094US|United States -- State Designated Tribal Statistical Area|||

So 89 = American Indian Reservation and Trust Land -- Federal and so on, but I'm hoping someone knows of a complete list I can slurp.
