Before April 30, 2008, all retail associates must return unsold migratory bird stamps to the unit reserve. Prior to May 31, 2008, all unit reserve stock custodians must ship unsold migratory bird stamps to the stamp distribution offices (SDOs)/stamp services centers (SSCs) for receipt.
The SDOs and SSCs must establish and communicate a schedule for postal retail units to submit all unsold migratory bird stamps for destruction based on the dates previously mentioned and on the following requirements:
Use PS Form 17, Stamp Requisition/Stamp Return, to return all unsold migratory bird stamps and annotate “Returned for Destruction” and “Bird Stamps”.
Ship unsold bird stamps along with the original and two copies of PS Form 17 to the SDO/SSC. Place the original PS Form 17 in a sealed envelope and tape it to the outside of the carton clearly marked as “Bird Stamps”.
