Prime Minister Mario Draghi signed a decree later the same day that officially launched the pass, which will allow people to access certain events and facilities in Italy as well as travel domestically and abroad.
The Certificazione Verde website lets people in Italy request the green pass, which is available in Italian, English, French and German.
The form, which comes in digital or paper versions, is free and contains a scannable QR code.
In order to claim the green pass it is necessary to provide at least one of the following: a vaccination certification, documentation showing that you have recovered from COVID-19, or a recent test with negative results.
Green pass certificates relating to vaccinations carried out to date will be made available by June 28, with those vaccinated being notified by email or text message with a code giving access to download the form onto a PC, tablet or smartphone.
Going forward, it will be possible to claim your certificate 15 days after your first dose of a vaccine (including the Johnson & Johnson single shot), within 48 hours of your second dose, the same day as you receive a negative test result, or within 24 hours of being confirmed recovered from COVID-19.
Certificates will remain valid until you get your second vaccine dose (if applicable), for nine months after you are fully vaccinated, six months after you recover, or 48 hours from when you get tested.
Italy plans to require a green pass to attend large gatherings such as weddings or concerts, with more and more public events expected to ask guests for the certificate as it becomes more widely available.
The green pass will also be valid for quarantine-free travel in the EU from July 1, with certificates issued in any member state valid throughout the rest of the bloc.
That means that residents of other EU countries planning to visit Italy should claim a certificate from their own country, which will be accepted in Italy.
Italy’s green pass comes ahead of the EU Digital COVID Certificate (EUDCC), which will allow free travel across the EU from July 1.
