The United States Postal Service Domestic Mail Manual requires each county auditor to include on the ballot, ballot instructions, mailing instructions, or return envelope the specific amount of first-class postage necessary to return the ballot by mail. This is not required:

1. (1) For ballots issued to service and overseas voters;
2. (2) For ballots returned using the business reply mail service;
3. (3) For ballots returned with postage prepaid by stamps, meter, or permit reply mail; or
4. (4) If the county auditor has an account with the post office guaranteeing payment of return postage due.
