What is the highest weight limit for domestic mail?

  1. 50 lb.

  2. 60 lb.

  3. 70 lb.

  4. 80 lb.

The correct answer is: 70 lb.

The highest weight limit for domestic mail is 70 pounds. This limit applies to Priority Mail and other specific mail services offered by the Postal Service for items sent within the United States. It is essential to know this limit, as it impacts how customers prepare their packages for shipment and determines the cost of postage. If a package exceeds 70 pounds, it cannot be sent through standard domestic mail services, and customers must explore alternative shipping options. Understanding the weight restrictions helps ensure compliance with postal regulations and avoids delays in mail processing or delivery.
