The document is card-sized as defined by ISO format ID-1 (prior to 2005 the DNI was size ISO ID-2; renewal of the card due to the size change was not mandatory, nor did previously-emitted cards lose validity). The front of the card presents photographs of the holder's face, their name, date and place of birth (the latter in coded form), gender and marital status; the bottom quarter consists of machine-readable text. Three dates are listed as well; the date the citizen was first registered at RENIEC; the date the document was issued; and the expiration date of the document. The back of the DNI features the holder's address (including district, department and/or province) and voting group. Eight voting record blocks are successively covered with metallic labels when the citizen presents themselves at their voting group on voting days. The back also denotes whether the holder is an organ donor, presents the holder's right index finger print, a PDF417 bar code, and a 1D bar code.
