The Chicago Area Consolidation Hub (CACH) is a package sorting hub for United Parcel Service. Located approximately southwest of downtown Chicago, the facility is in two municipalities. Five-sixths of the UPS properties lie within the Village of Hodgkins, Illinois, with one-sixth being situated in the neighboring Village of Willow Springs. All of its fire, police and infrastructure are attached to Hodgkins. A public shipping and receiving facility is in Willow Springs while the huge transfer and loading facilities are in Hodgkins.
This facility serves as a central sorting facility for packages traversing the country and internationally. Construction of the CACH facility began in November 1991 at the site previously occupied by the GM Truck and Bus manufacturing plant. The facility has an area of, and has a perimeter of . It employs over 8,000 people across four shifts. Packages are only handled during loading and unloading - all sorting takes place through a complex system of conveyor belts and push paddles, utilizing high-speed cameras to read the destination from a smart label to sort a package to its outgoing trailer.
While CACH does not service package cars, the facility sorts approximately 1.6 million packages per day. During the months of November and December, volume can exceed 3 million packages per day. UPS's web tracking system used to list the CACH as "CACH, IL." Since there is no city named CACH, this confused customers. As a response, the company now lists the hub as "HODGKINS, IL" or "Hodgkins, IL."
UPS also has a location called "Hodgkins, IN" that is sometimes confused with CACH. It is a place where trailers switch in between singles, doubles, and triples, because the Illinois turnpike doesn't allow some or all multiple trailers and the Indiana turnpike does. The facility is located in Hammond, IN at I-90 ( Indiana Toll Road) (Indiana Hwy 5) & Calumet Ave ( U. S. Hwy 41) off of the eastbound freeway entrance ramp . It is informally called West Point by UPS. There's another UPS truck parking lot south of the nearby Public Storage.
