Mail Operations

PSC provides official government mail services to all federal agencies. We offer a comprehensive end-to-end solution for our customers. Let us manage your mail from start to finish ― we can design, address, sort, and deliver your mail pieces to the U.S. Postal Service (USPS). Our expertise and relationships with the USPS and other carriers means we can go beyond what is standard, to find the smartest, most cost-effective, and quickest mailing solutions, whether you're mailing a few postcards, receiving hundreds of pieces of mail, or sending thousands of letters.


PSC prepares and dispatches outgoing mail utilizing our "Rate-Shop" system to compare real-time information from our carriers and identify the most cost-efficient vendor based on weight, destination, and time sensitivity of your delivery. We also collect interoffice mail from designated mail stops each business day and perform special "hand carry" services upon request. Our centralized mail service and operation allows our customers to reduce operating costs such as space rent, salaries, equipment cost, and maintenance expenses. In addition, the speed and accuracy of our courier and in-house delivery services enable our customers to perform their tasks in a timely manner.

  • Incoming USPS and courier mail
  • Interoffice mail
  • Certified, registered, and foreign mail
  • Special "hand carry" messengers
