What will happen if my already-sent check is posted to my USPS prepay account after I have begun funding postage?

The funds will be credited to your USPS prepay account and subsequent downloads will draw against that balance before any further draw against your account. Please call our Customer Interaction Center to request a transfer of funds from your prepay account to your NeoFunds/TotalFunds account. A representative can be reached at 1.800.NEOPOST (636.7678), Monday through Friday between the hours of 7 a.m. and 6 p.m. (CST).
