Apply for a passport replacement if you lose your passport abroad
Source: BUS Rheinland-PfalzIf you have lost your passport abroad or it has been stolen, you must obtain replacement travel documents for your return or onward journey from the German diplomatic mission in your destination country.
Depending on whether you want to return directly to Germany or travel to other countries, either a travel document that is only valid for entry into Germany or a new passport or temporary passport must be issued.
Please note that some countries require the entry stamp in the passport as proof of legal entry when leaving the country. In these cases, you may have to apply for an exit visa.
