What is an e-Residency?E-Residency is a government-issued digital identity and status and enables you to be a digital entrepreneur, and start an EU-based company entirely online. The first country to offer such a solution was Estonia. When you sign up for Estonian e-Residency, you receive a government-issued smart ID card that provides digital identification and authorization. It gives you the opportunity to sign documents remotely, access secure services, and make secure transactions. As of April 2019, over 53,719 people from over 175 countries have applied for e-Residency.
