30071:3000 identifies Customer community in general..

Then we have location code for customers...

3010 means originated from ZOA (San Francisco/Oakland area).
3020 means originated from ZBW (Boston area).

and so on and so forth as listed in http://www.occaid.org/occaid-bgp.html

Same story with 9xxxx. 9000 identifies internal originated.
Then 9010, 9020, etc are location codes.

Does this help you? :) Let me know if not..
