Johnson Space Center uses a Houston mailing address but lies outside city limits

NASA's Lyndon B. Johnson Space Center is addressed as 2101 NASA Pkwy, Houston, TX 77058, but the JSC is located in unincorporated Harris County (the Clear Lake area) and is not within the City of Houston's municipal limits. This is an example of the wider regional oddity where many facilities and neighborhoods use 'Houston' postal addresses while lying outside the city's corporate boundaries. The mismatch between postal city names and municipal jurisdiction is common in the Houston metropolitan area and is reflected in official county and city maps.
