Identity
A national identity card (national ID card) is a government-issued card that proves a person's identity and citizenship within their country. Standard across Europe and much of the world, it shows your name, photo, date of birth, a document number, and often a national ID number. The United States has no such card. Americans use driver's licenses, state IDs, and passports instead.
EU nationals can travel across all 27 EU countries plus Iceland, Liechtenstein, Norway, and Switzerland with a valid national identity card: no passport required.

Overview
Most countries issue a national identity card as the everyday proof of who you are: you show it at banks, government offices, hospitals, and when signing contracts. In the European Union it doubles as a travel document: an EU national can cross all 27 member states plus Iceland, Liechtenstein, Norway, and Switzerland with just their ID card, no passport required. Cards go by local names (Dowód osobisty in Poland, Personalausweis in Germany, DNI in Spain, Carta d'Identità in Italy) but carry the same core data.
The United States is the outlier. There is no federal national ID card; the REAL ID standard that took full effect on May 7, 2025 sets minimum security rules for state-issued driver's licenses and ID cards, but it deliberately does not create a single national identity document. So when an American is asked for their "national ID," the practical equivalents are a driver's license, a state ID card, or a US passport.

How long to keep it
Keep while it's active, then you can let it go
An ID card is the document you most often need on short notice (proving identity to a bank, a landlord, a border officer, or a hospital) and it's the one that's hardest to locate in a hurry. A copy of both sides also speeds replacement if the physical card is lost or stolen, since it preserves the card number and issuing details. Keep expired cards out of circulation, but don't rely on a drawer to find the current one in time.

Granite recognizes a national identity card, whether it's a Polish Dowód osobisty, a German Personalausweis, or any other country's card, and pulls the holder name, document number, issuing country, national ID number, and issue and expiration dates. It files the card with your identity documents and the cardholder's person record, treats the document and national ID numbers as sensitive, and warns you before the card expires, well ahead of any renewal.
