A Belgian identity card (Dutch: Identiteitskaart, French: Carte d’identité, German: Personalausweis) is a national identity card issued to all citizens of Belgium aged 12 years old and above.

Foreigners resident in Belgium are issued with a Belgian resident card (Dutch: Verblijfstitel, French: Titre de séjour, German: Aufenthaltstitel), which appears similar, but is legally distinct.

Nevertheless, the term "identity card" is often used to refer to both the identity cards issued to citizens and the resident cards issued to foreigners.

The main card types currently in issuance are as follows:

Third country nationals refers to foreigners who are not EU/EEA/Swiss nationals.

Cards are issued according to the ISO/IEC 7810 standard using the ID-1 size format, similar to credit cards.

They conform to ISO/IEC 7816 and have a 3-line machine-readable strip on the back starting with IDBEL.

Cards issued to Belgian citizens and EU/EEA/Swiss citizens are green. They carry a heading of "BELGIUM" and the type of card (e.g. "IDENTITY CARD" or "EU+ Card"), written in all three national languages (Dutch, French and German) as well as in English. The remaining fields are bilingual - English in combination with either Dutch, French or German - depending on the official language of the place of residence of the subject.
