The USPS Business Customer Gateway (BCG) communicates with the Business System Administrator (BSA) for approvals, etc. If your previously-assigned BSA is no longer with your company, refer to the instructions located at https://gateway.usps.com/eAdmin/view/support
to create a new BSA. If you do not have a BSA, contact the USPS Help Desk at 877-264-9693.
