A resolution recognizing the 250th anniversary of the postal service of the United States.

S.Res. 337 is a non-binding resolution that would recognize and commemorate the 250th anniversary of the United States Postal Service. As a Senate resolution, this measure does not have the force of law and does not require presidential signature. Instead, it serves as an expression of the Senate's recognition of this milestone in American postal history.

This resolution has no direct practical impact on citizens' daily lives or government operations. It is a ceremonial measure intended to acknowledge the historical significance of the postal service, which has been a fundamental institution in American communications and commerce for two and a half centuries. The resolution was introduced in July 2025 and was discharged from the Senate Committee on Homeland Security and Governmental Affairs by unanimous consent in October 2025, indicating broad support among senators for recognizing this anniversary.
