Where do I send my payment to add postage my mail machine?

PLEASE.... Do not send your payment to Neopost USA. Checks for postage must be made payable to "USPS" and sent to one of three processing centers, which are contracted by USPS to accept these payments. You should choose the processing center closest to your local area. Once your check is received, the processing center posts it to your postage account within 7 - 10 business days.


In order to ensure the fastest possible availability of your postage, please include your postage account number on your check. 


Please choose your brand to find the specific mailing address and instructions for making payment: Neopost | Hasler
