To enter Bulgaria, foreign citizens must have a valid travel document issued in their country of citizenship. Foreigners with a Bulgarian Long-term or Permanent Residence Permit are obligated to carry the permit certificate or card as well. Foreigners failing to present these identification documents to the controlling authorities are fined. The Identity Card is the national identification document issued to all Bulgarian citizens from the age of 14. It is compulsory for Bulgarians to carry the ID at all times.
