The Republic of Estonia is the first country to offer e-Residency — a transnational digital identity available to anyone in the world interested in administering a location-independent business online. e-Residency additionally enables secure and convenient digital services that facilitate credibility and trust online.
All of these (and more) efficient and easy-to-use services have been available to Estonians for over a decade. By offering e-Residents the same services, Estonia is proudly pioneering the idea of a country without borders.
e-Residents receive a smart ID card which provides:
Digital signatures and authentication are legally equivalent to handwritten signatures and face-to-face identification in Estonia and between partners upon agreement anywhere around the world. The e-Resident ID card and services are built on state-of-the-art technological solutions, including 2048-bit public key encryption. The smart ID card contains a microchip with two security certificates: one for authentication, called PIN1, and another for digital signing, called PIN2. PIN1 is a minimum 4-digit number for authorization, PIN2 is a minimum 5-digit number for digital signature.
e-Residency does not confer citizenship, tax residency, residence or right of entry to Estonia or to the European Union. The e-Resident smart ID card is not a physical identification or a travel document, and does not display a photo.
