To designate the facility of the United States Postal Service located at 417 West 7th Street in Columbia, Tennessee, as the "Pharmacist's Mate First Class John Harlan Willis Post Office Building".

H.R. 6808 proposes to designate the United States Postal Service facility located at 417 West 7th Street in Columbia, Tennessee with a new official name: the "Pharmacist's Mate First Class John Harlan Willis Post Office Building." The bill honors John Harlan Willis by attaching his name and military rank to this federal postal facility.

The bill has been approved by its committee and is now eligible for a floor vote in the House of Representatives. If enacted, the practical effect would be that the postal facility in Columbia would officially be known by this commemorative name. This type of legislation is a common way Congress honors individuals for their service or contributions. Citizens in Columbia would see the new name on the building, and official postal correspondence from this location would reference the designated name.
