The purpose of the Protect Our Letter Carriers Act of 2025 is to enhance the safety and security of United States Postal Service (USPS) letter carriers. The legislation aims to address the rising concerns about violence against postal employees and to improve the security of mail collection systems. Key provisions of the Act include the allocation of .4 billion each year from 2026 to 2030 for the USPS to upgrade security measures. This funding will be used to install high-security mail collection boxes and to replace older universal mailbox keys with electronic versions.
