Washington, DC’s Attorney General Brian Schwalb is suing Amazon for allegedly excluding certain ZIP codes from enjoying Amazon Prime’s speedy delivery. Schwalb claims that, beginning in 2022, Amazon stopped using its in-house delivery systems for Wards 7 and 8 while still charging those customers the same amount for a Prime subscription. According to Census Reporter, Ward 7 and Ward 8 are 83 percent and 82 percent Black, respectively.

According to the suit, instead of using its own trucks, Amazon relied on UPS and USPS carriers to make deliveries — a decision that resulted in longer delivery times. Only 24 percent of packages to these Wards were delivered within two days. Schwalb also alleged that Amazon didn’t notify any Ward 7 and Ward 8 residents about these changes.

Worryingly, this isn’t the first time Amazon has been called out for excluding majority-Black neighborhoods from the full benefits of a Prime membership. A damning 2016 report in Bloomberg indicated the practice was common across several metro areas. Amazon has since provided Prime Free Same-Day Delivery to Boston’s Roxbury neighborhood, Chicago’s South Side and the Bronx in New York City.
