Estonia’s digital society is built on secure, convenient, and legally binding e-identity tools: the ID-card, Digi-ID, and Mobile-ID. These allow you to log into e-services, sign documents digitally, and manage your business or personal affairs fully online.

ID-card & Digi-ID

The ID-card and Digi-ID are physical smart cards used to:

• Access Estonian e-services (e.g. Business Register, Tax Board, banks)

• Digitally sign documents with legal validity

• Authenticate identity securely online

• Encrypt files and communications

To use them, you’ll need:

• A card reader

• ID-card software, downloadable at installer.id.ee

• PIN codes, issued with the card (replacements available at Estonian service points or embassies)

• Valid certificates, which you can check and renew at id.ee

• A computer with internet access

Mobile-ID – Digital ID on Your Phone

Mobile-ID offers the same functionality as the ID-card, but without the need for a card reader. Instead, it works directly from your mobile phone.

How it works:

• Requires a special Mobile-ID SIM card, issued by Estonian mobile operators

• Stores private keys and signature functionality directly on the SIM

• Actions are confirmed using PIN1 (authentication) and PIN2 (signing)

• Perfect for users who prefer secure identification on the go

e-Residency Digital ID

If you are an Estonian e-resident, your e-Residency card allows you to access all of the above features (except Mobile-ID). You can:

• Manage your company

• Sign documents digitally

• Use secure government and private e-services
  Note: E-Residency does not grant legal residence, tax residence, or the right to enter Estonia or the EU.
