At a USPS facility, retail post-office operation, or specialty postal-services operation, you sell stamps and postage products — handling stamp sales, supporting customer postage needs, processing related transactions, and the retail-counter work that postage sales involve.
Stamp-clerk work happens at the post-office retail counter — customers buying stamps in various denominations and quantities, customers needing specialty postage (collector stamps, international postage, specific postal-rate stamps), and the cash-handling and POS work that retail postage sales generate. The clerk works the USPS retail systems (POS One), the cash drawer and inventory of stamp products, and the customer-service interactions that stamp sales involve. Sales accuracy and customer service are the operating measures.
The reality is that dedicated stamp-clerk positions have largely been absorbed into broader postal-clerk roles — modern USPS retail clerks handle stamps along with parcels, certified mail, P.O. Boxes, passport applications, and other postal services. The standalone stamp-clerk designation reflects historical specialization more than current employment categories.
It fits people who are warm at the customer counter, accurate with cash and POS systems, and patient with the customer-service interactions retail postal work involves. USPS-specific training (484/485 exam for clerks) and customer-service experience anchor advancement. The trade-off is the customer-service intensity during peak postal periods (especially December) and the modest federal pay typical of postal-clerk positions before tenure builds.
