Compulsory for anyone not residing in Belgium to present a Digital Covid Certificate upon entry; i.e. a recent test. Exceptions apply (stays of less than 48 hours). No test obligation for anyone who enters the country (resident and non-resident) with a certificate. For Belgian residents without a certificate travelling from a dark red country or a third country not on the white list of Europe should undergo a rapid antigen (RAT) or a PCR test on day 1 after their arrival. For people from countries or regions with circulation of a new variant Concern (VOC) strict testing rules remain unchanged.
