What is a Unique Zip Code?

Essentially, a "unique ZIP code" is a ZIP code that's assigned to a single, high-volume mail receiver. Here's a breakdown:   

• Purpose:
  • These ZIP codes are used to streamline mail delivery for organizations that receive a large amount of mail.   
  • This includes places like:
    • Government agencies   
    • Large corporations   
    • Universities
    • Hospitals
    • Miliary installations
• How it works:
  • Instead of the USPS delivering mail to individual offices or departments within the organization, they deliver it to a central location.   
  • The organization then handles the internal distribution of the mail.
• Key characteristics:
  • They are non-geographic, meaning they don't correspond to a typical residential or street-based area.   
  • They are assigned to entities with a very large volume of mail.   

In simpler terms, it's a dedicated ZIP code for places that get a ton of mail!
