Visiting Bulgaria

Currency: The local currency is the Bulgarian Lev (1 Lev ~ 0.5 EUR). Credit/debit cards (VISA, MasterCard, Maestro) are frequently accepted in hotels and larger shops throughout the country. However, you should have some cash when travelling (to buy a metro ticket at the airport station or to take a taxi). Getting some cash from an ATM might be more convenient than using exchange offices.

Electricity: We use a 230-V/50-Hz electricity network. Make sure your appliances are compatible (or get a travel adapter).

Emergency numbers: If you need assistance from an ambulance or the police, call 112 from any phone (including your mobile phone while roaming).

Visa: Participants from certain countries must have a Bulgarian visa from a Bulgarian embassy or consulate. In this case one must send his names, birth date and international passport data to the hosting the conference institution and a standard invitation letter can be received. E-mails:;
