Cardless e-Residency update
Estonia has officially announced a transition toward a 100% cardless, biometric mobile app system for e-residents. This update is expected to eliminate the need to visit an embassy to pick up a physical card and is expected to cut the application waiting time from 2 months to just 2 weeks. Read the official announcement here. Until the new system is fully rolled out, this guide covers how to set up and use your current physical e-Residency Digital ID kit.
Quick answer: To use your Estonian E-Residency Digital ID card, install DigiDoc4 Client, connect the USB card reader, insert the card chip-side up, use PIN 1 for secure login, and use PIN 2 for legally binding digital signatures. Smart-ID can then be set up as a card-free phone-based alternative for many services.

Check that the Digital ID card is detected
Launch the DigiDoc4 Client. It should immediately read your Estonian E-Residency Digital ID card and display your name and ID number. You can now use PIN 1 to verify your identity and PIN 2 to confirm signatures.

Most public services in Estonia are accessible online. Test your card by logging into the state portal eesti.ee. Select “Login with ID Card”, follow the browser prompts, and enter PIN 1 to see what services are available to you.
If you plan to start a company in Estonia, you will later use the same Estonian E-Residency Digital ID to sign incorporation documents and manage your company in the Commercial Register. For a detailed walkthrough, see our guide on how to start a company in Estonia.

As your business grows, the same digital ID card remains the central tool for identification, access control, and document signing in the Estonian system. This consistency is one of the main efficiency benefits of E-Residency.
Smart-ID Setup with Your Estonian E-Residency Digital ID
Smart-ID is a time-saving, card-free alternative that uses your smartphone for secure authentication. Once your Estonian E-Residency Digital ID card is active:
- Download the Smart-ID app on your smartphone.
- Use your ID card and reader to authenticate the app for the first time.
- After activation, you can log into services like the Commercial Register, eesti.ee, and banking portals using only your phone.
Smart-ID is particularly useful when you travel and do not want to carry a card reader. However, the digital ID card remains the primary document and may still be required for some procedures.
Security Tips for Your Estonian E-Residency Digital ID
Software and browser
- Browser extensions: Ensure the “Token Signing” or similar Estonian ID card extensions are enabled in your browser (Chrome, Firefox, Safari).
- Regular updates: Keep DigiDoc4, your operating system, and browsers up to date for security patches.
Card and device safety
- Lost card: If you lose your physical card, you can still use Smart-ID (if already set up) to access services while you apply for a new card.
- Separate devices: Consider using a separate computer or user profile for business activities to reduce the risk of malware.

Yes. Under EU regulations (eIDAS), the Qualified Electronic Signature (QES) created with your Estonian E-Residency Digital ID card is legally equivalent to a handwritten signature for most contractual and corporate purposes across Europe.
