So, not only is it possible for a person to have the same RG number as a person from other state (which is usually dealt with by specifying the state which issued the ID card), but it is also possible to (legally) have more than one RG, from different states.
Så, det er ikke kun muligt at have samme RG nummer som en person fra en anden stat (som normalt behandles ved at angive den stat, der har udstedt ID-kort), men det er også muligt at (lovligt) have mere end en RG, fra forskellige stater.
