The dabbawalas (also spelled dabbawallas or dabbawallahs, called tiffin wallahs in older sources) constitute a lunchbox delivery and return system that delivers hot lunches from homes and restaurants to people at work in India, especially in Mumbai. The lunchboxes are picked up in the late morning, delivered predominantly using bicycles and railway trains, and returned empty in the afternoon.
Lunch boxes are marked in several ways:
1. Abbreviations for collection points
2. Colour code for starting station
3. Number for destination station
4. Markings for handling dabbawala at destination, building and floor
A colour-coding system identifies the destination and recipient. Each dabbawala is required to contribute a minimum capital in kind, in the form of two bicycles, a wooden crate for the tiffins, white cotton kurta-pyjamas, and the white Gandhi cap (topi). Each month there is a division of the earnings of each unit. Fines are imposed for alcohol, tobacco, being out of uniform, and absenteeism.
A collecting dabbawala, usually on bicycle, collects dabbas either from a worker’s home or from the dabba makers. As many of the carriers are of limited literacy (the average literacy of Dabbawallahs is that of 8th grade), the dabbas (boxes) have some sort of distinguishing mark on them, such as a colour or group of symbols.
The dabbawala then takes them to a sorting place, where he and other collecting dabbawalas sort the lunch boxes into groups. The grouped boxes are put in the coaches of trains, with markings to identify the destination of the box (usually there is a designated car for the boxes). The markings include the railway station to unload the boxes and the destination building delivery address. Some modern infrastructure improvements such as the Navi Mumbai Metro are not used in the supply chain, as cabins do not have the capacity for hundreds of tiffins.
At each station, boxes are handed over to a local dabbawala, who delivers them. The empty boxes are collected after lunch or the next day and sent back to the respective houses. The dabbawalas also allow for delivery requests through SMS.
