They do that in Mumbai, sorta, but using tags they put on the clothes. You drop off a bag of laundry, it gets picked up and taken to this central washing area in town. Someone labels every piece of clothing, and then throws all the clothes together with everyone else's clothes for washing. After washing they fold and separate all the clothes and you get everything back (at least I always did). I think this has been going on since at least the 19th century.
