Digital information Cards issued since 2005 contain a chip, which includes additional information, including: two digital certificates (authentication and, for adults, signing) residential address up to two fingerprints (since 2020) National Register number and card number Cards include two numbers that should not be confused with each other. The National Register number is issued to the person upon their first registration (i.e. usually at birth for Belgian citizens) and held for life. It comprises 11 digits in the form yy.mm.dd-xxx.cd where yy.mm.dd is the birth date, xxx is a sequential number (odd for males and even for females) and cd a check-digit. The card number applies only to the card in question and can take several different formats: Belgian citizens: 12 digits in the form xxx-xxxxxxx-yy where yy is a check digit calculated as the remainder of dividing xxxxxxxxxx by 97 (if the remainder is 0, the check number is set to 97) Third country nationals: nine digits in the form xxxxxxx xx EU/EEA/Swiss citizens: a letter and nine digits in the form B xxxxxxx xx Administration Issuance Residents of Belgium (both Belgian citizens and foreigners) receive their identity/resident cards from their local municipality. Belgian citizens who are resident abroad can apply for renewal of their identity card at their local Belgian embassy or consulate. The cost is usually approximately €25 (as of 2020) depending on the municipality or embassy. Manufacture The cards are manufactured by the Thales Group and over 28 million have been issued.
