Número de Identificação Militar (NIM) — military identification number
An eight-digit number assigned automatically to a citizen when they are entered on the military register: the first six digits are random, and the last two show the year in which they turn 20. It appears on the cédula militar.
Where you come across it. The cédula militar; the subject line of a letter to the DGRDN explaining why you missed National Defence Day.
Don't confuse it with your Cartão de Cidadão number: you use the CC number to find yourself on the call-up lists, while the NIM appears later, on the cédula militar.
