ZIP code 20997 serves another Suburban Maryland USPS Business Reply Mail (BRM) facility, this one in the North Potomac area of Montgomery County approximately 20 miles from Washington, D.C. Business Reply Mail enables companies to prepay postage for customer responses, paying only for mail actually returned. Together with ZIP 20897, these designations support BRM processing across suburban Maryland's northern tier. This postal designation has served the facility for over two decades.
The facility operates as an internal postal processing operation, which explains the absence of Census demographic data, ZIP+4 delivery codes, and building directories. Silver Spring serves as the valid mailing city despite the facility's North Potomac location, reflecting USPS regional mail routing patterns. Census demographic data is not available, consistent with operational postal facilities without residential population.
