U.S. Postal Service by the numbers

As of 2018, there were 31,324 retail post offices in the U.S. managed by the postal service. This represents a decrease from three years prior in 2015 when there had been 31,606 retail post offices. Online mail services have earned their own place on this list.

A whopping 838.7 million customers visited a retail U.S. post office in 2018. For comparison, the U.S. population was estimated to be 329.10 million that same year. This would average out to every U.S. citizen going to a post office roughly two and a half times.

All of those visits to the post office (see previous slide) resulted in $12.7 billion in retail revenue. If the post office was not government-run, this revenue would have earned a ranking as the 35th top retailer for 2018, behind AT&T and ahead of Gap.

Of the 634,447 total employees of the U.S. Postal Service, 497,157 were career employees in 2018. Career employees receive full employee benefits and privileges, such as health insurance and retirement.

The almost 500,000 career employees of the U.S. Postal Service comprise seven different unions that have collective bargaining agreements with the USPS.

Not all of the 2.3 billion visits to the usps.com were just to track a package. Visits to the postal store on usps.com for stamps and retail brought in $301 million in online sales in 2018.
