What must the supervisor do to complete a stamp credit establishment?

To establish a stamp credit, the supervisor is required to complete PS Form 3369 in duplicate. This form is a formal and necessary step in the process, serving as an official record that documents the establishment of the stamp credit. By filling out this form, the supervisor ensures that all relevant details are captured properly and accounted for, which is crucial for inventory management and financial accuracy within the postal system.

Other methods, such as issuing a verbal approval or signing off on existing credits, do not provide the documented evidence necessary for establishing a stamp credit. Additionally, simply filling out a stock request form does not meet the specific requirements needed for establishing a credit. The formal completion of PS Form 3369 is essential for compliance and maintaining accurate records within the USPS operations.
