Frequently asked questions

General information about the certificate

How can I obtain a certificate?

The EU Digital COVID Certificate is issued by the Ministry of Health of the Republic of Croatia. You may request a certificate online using a dedicated application or from the authority licensed to issue such certificates (Croatian Health Insurance Fund, HZZO), which shall issue a paper certificate or deliver it by e-mail.

You can store the digital version on your mobile device, send it by e-mail or print it. Regardless of the version, the certificate will contain a QR code including general information and a digital stamp authenticating the certificate.

You can access the online platform via the e-Citizens system using a Level 2 Credential – Substantial Security or a Level 3 Credential – High Security.

Please find a list of credentials including such security levels HERE.

Which information and documents do I need to request my certificate via the e-Građani portal?

Other than the credentials of the required security levels (2 and 3), you do not need to provide any further information or documents. The system automatically retrieves user data from the database maintained by the Ministry of Health and a certificate is generated by clicking “Zatraži potvrdu”. 

How does the certificate work?

The EU Digital COVID Certificate contains a QR code including a digital signature to protect against falsification, which is based on ICAO PKI specifications.

The certificate is verified by scanning the QR code and verifying the digital signature.

The digital signature key stored in a secure database is held by the issuer.

The European Commission has established an EU gateway where public components of national digital signature keys will be exchanged in a single place to allow for interoperability of EU Digital COVID Certificate systems. Personal data inserted in the certificate will not go through the EU gateways because this is not required for digital signature validation.

May I use the certificate via my mobile phone?

Yes. You can store the certificate as a PDF file and present it to the officer responsible for reading the QR code and other relevant information.

How will the certificate help me move freely?

The EU Digital COVID Certificate is accepted in EU Member States and will help ease the restrictions present in the form of measures taken by Member States in a coordinated manner.

When traveling to or staying in an EU Member State, each citizen of the EU or a citizen of a third country formally residing in the EU shall, as a holder of an EU Digital COVID Certificate, be able to demonstrate in an effective and interoperable manner his/her COVID-19-related health status. If a particular Member State should continue to require that holders of valid EU Digital COVID Certificates be placed in quarantine or additionally tested, it shall be required to duly notify the Commission and all other Member States thereof and give reasons for its decisions.

Will I be able to travel to another EU Member State if I have not yet been vaccinated?

Yes. The EU Digital COVID Certificate should facilitate free movement within the EU. Being a fundamental right in the EU, free movement will not be made contingent upon the EU Digital COVID Certificate. You may also use your EU Digital COVID Certificate to provide a negative test result, which is frequently required as a result of the public health restrictions in place.

Such certificate allows Member States to adjust their present public health restrictions to facilitate cross-border travel for their citizens.

Does it matter which vaccine I received?

Vaccination certificates in Republic of Croatia will be issued to vaccinated persons for all vaccines against COVID-19 approved by the European Commission.

Are my personal data secure?

The EU Digital COVID Certificate includes general information such as your name, date of birth, certificate issue date, relevant information concerning your vaccination, testing and recovery, and a unique identifier.

The certificate itself contains only a limited set of strictly necessary data. A Member State you visit may not retain such information. Only the information about the issuer and digital signer of the certificate will be checked for validation and authentication purposes. All health information remains stored in the Member State issuing the EU Digital COVID Certificate.

Are minors eligible for the certificate?

The EU Digital COVID Certificate for recovery, vaccination and testing can also be issued to minors.
