From 2011, all foreign nationals who reside permanently in Estonia must hold an ID-card or residence permit card.
Digital documents (ID-card, digital ID, e-Resident’s digital ID, etc.) enable identification of the user in electronic channels.
Everything becomes worn out when heavily used. In order to guarantee that your ID-card or other digital document, such as digital ID, lasts for as long as possible, keep it safely in the document compartment of your wallet
Mobile-ID is a SIM card based mobile identification document which is always with you when you have your mobile phone.
