>Why is this not practical. You would have to do this either way. Only now you have a normalized database. You just have to add 1 record for each different rate in the the area code. Under this scheme, each area can have a different number of defined rates. The benefits you now gain outweigh the time it takes to add 20 or so new records for each new area code.

And in addition to Mark's comments, your other code wouldn't have to be updated when you add a new area code. If you add new fields to your non-normalized table you must update every function that uses that table to include the new fields.
