A postage meter was moved from a branch office in California to an office in Vermont. The machine has yet to be updated. Specifically, it still prints "sent from 90210" instead of "sent from 05602." Will the post office in Vermont return the metered mail because of this zip code discrepancy?

I'm looking for a web page that asks for a zip code (or an address) and returns the voting district, what candidates are running on the ballot and any other measures or items up for the vote. Does anything like this exist on a national, state or more local level?
