National ID cards — how other countries handle it

The United States is one of the few developed countries without a mandatory national ID card. Understanding how other countries manage national identity documentation provides useful context for why US state driver's licenses function the way they do and why there is no single US identity document standard.

Germany

Germany issues a mandatory national ID card (Personalausweis) to all citizens aged 16 and over. The card contains an RFID chip with biometric data and serves as a travel document within the EU. Physical production is centrally managed by the Bundesdruckerei, ensuring a single consistent security standard across all cards. The card is also a legal requirement for banking, government services, and age-restricted purchases in most contexts.

United Kingdom

The UK does not have a mandatory national ID card — a national ID scheme was proposed and developed in the 2000s but was scrapped in 2010. Driver's licences (with photo) and passports serve as primary identity documents. The absence of a national ID creates a situation similar to the US, where multiple document types are accepted for identity verification and driver's licences carry disproportionate identity weight relative to their original driving-authorization purpose.

Japan

Japan's My Number Card is a voluntary national ID that functions as both identity document and administrative portal. Unlike German cards, it is not mandatory and adoption has been slow despite government incentives. Many Japanese residents still use their driver's license or health insurance card for day-to-day identity verification.

The US approach

The combination of state driver's licenses as de facto national ID, federal REAL ID Act minimum standards, and voluntary adoption of Enhanced Driver's Licenses represents a compromise between federal standardization and state sovereignty that satisfies neither those who want stronger national ID standards nor those who oppose federal identity infrastructure.

The patchwork identity system in the US — where each state designs and issues its own credential — creates a verification challenge that unified national ID systems in other countries avoid entirely. Whether that decentralization is a feature or a problem depends on whether you value state control over identity infrastructure or the standardization that makes nationwide verification more reliable. For now, the practical result is 50-plus distinct design standards that checkers have to recognize.
