Internal Schengen document checks

Document checks are frequently conducted when entering Germany from Poland. It is recommended to have valid travel insurance, which can be purchased online (e.g., ADAC). Within Germany, especially on trains, random insurance checks are less common, but border checks are more stringent.

Despite the absence of customs control within the Schengen Area, border police checks can still occur between member states. Specifically, border control checkpoints exist between Austria and Germany. When entering Austria from Hungary, border police may conduct selective checks on vehicles and passengers.

Border crossing experience from Milan to Germany via bus in Basel. Passengers with Schengen visas (French in this case) had their passports checked by border guards who entered the bus. Standard questions about trip purpose and duration were asked, but no additional documents were requested. The process was described as not as intimidating as expected, despite thorough preparation.

While there isn't formal border control on trains between the Czech Republic and Germany (within the Schengen Area), selective document checks by authorities do occur on routes such as RE25, RE33, and branded trains like Prague-Dresden and Prague-Munich. Passengers should always carry their identification and relevant documents. For those in the process of renewing their residence permit (e.g., with an ABH certificate or appointment confirmation), these documents might be helpful during checks.

German Federal Police (Bundespolizei) actively conducts random spot checks (Schleierfahndung) on passengers arriving from Strasbourg (France) to Kehl (Germany) via the cross-border tram line. Checks are most common at the first stop, Kehl Bahnhof. Travelers must carry valid ID/passport and a Schengen visa or residence permit (Aufenthaltstitel) even within the Schengen area.
