If you only have 2,000,000 rows, why not store them all in the same
table?  It should be a lot faster than checking one hundred tables
each time.  It sounds like you could do something like this:

SELECT data FROM zips WHERE zipcode = '$zip' ORDER BY version DESC LIMIT 1;

If your average record size is less than about 1k, you could cache the
entire thing in memory.
