Expired or lost passports – PolandCoronavirus: safely resuming travel
As a citizen of the Republic of Poland you have the right to return to Poland even if you do not have a document which entitles you to cross the border or if the document you have (a passport or an ID) has expired. However, in this case, only an expired passport (not an ID) will be held at the border and a new document must be issued before you can leave the country again.
Bear in mind that if you travel without a document or one which has expired your return to Poland could be problematic, for example because of airline or third-country regulations, the optimal solution would be to get the document at a Polish diplomatic post or consular office. If there is no Polish post in a third country you should apply for an Emergency Travel Document at a diplomatic post of another EU member country.
