A Government office, specially created for this task, the OFICODA, distributes the "libreta" to all citizens each year, in the form of a small booklet. This booklet contains pages indicating the exact number and age groups of persons composing the family nucleus (typically, one booklet is released per family nucleus), as well as any dietary indications. A person's products are distributed only at the "bodega" that serves their area of official residence. A person cannot receive their products somewhere else, so each change of address requires returning to the OFICODA to update the booklet's data, and those living away from their registered addresses have to return to the previous area for their supplies.
