Estonia is among the red countries and when traveling to Norway, all travellers arriving in Norway are from 26.11 2021 required to complete entry registration. An exemption will be made for children under the age of 16 and selected groups. All arriving travellers are required to produce such confirmation and a COVID-19 certificate, if applicable, to the police at border control. It will be reintroduced the requirement of documentation of a negative test taken less than 24 hours before arrival for people who cannot produce a verifiable COVID-19 certificate showing that they are fully vaccinated or have recovered from COVID-19 during the past 6 months. This will apply regardless of which country the person has travelled from, but will not apply to travellers under the age of 18. More information.

Green country status requires an infection rate of 50 / 100,000 and negative tests of less than 4%. The data is updated every week on Monday.
