By Mail

You can send a check, money order, cashier’s check, 529 payment, or certified funds through the mail. Mail payments at least two weeks before the due date. Payments sent in the mail must be received by close of business, 4 p.m. Mountain Time, on the due date. Postmarks do not constitute receipt of payment. Postmarks and post-dated checks are not honored. Priority mail is not guaranteed to be received on time, so we encourage paying online by 11:59 p.m. on the due date, as an alternative.
