The postal code printed by your postage meter should be your postal code.  If your postage meter is printing the incorrect postal code a new one will need to be downloaded.  An address change may be required, this can be updated via My Account or have a customer support agent perform the address change request.

The updated postal code will be made ready to download by Pitney Bowes, contact customer support from 8 am to 8 pm Eastern Time. Please have your model number and the new address ready.
