Bulgaria operates on the Bulgarian lev, abbreviated BGN and denoted by the symbol лв. The lev divides into 100 stotinki. Since 1997, the currency has been pegged to the euro under a currency board arrangement administered by the Bulgarian National Bank, initially at 1000 lev to one Deutsche Mark and since 1999 at 1.95583 lev to one euro. This fixed rate eliminates currency fluctuation risk for travelers planning euro-zone itineraries before or after Bulgaria. Bulgaria joined the European Union on January 1, 2007, but has not yet adopted the euro as its currency despite repeated target dates. The government aims for euro adoption, with 2025 mentioned as a possibility pending European Central Bank approval of convergence criteria. Cash remains dominant in daily transactions outside Sofia and major coastal resorts. The National Statistical Institute reported in 2022 that approximately 70 percent of household transactions occur in physical cash. ATMs labeled банкомат appear throughout cities and towns, dispensing lev in denominations of 10, 20, 50, and 100. Machines in tourist areas including Varna, Burgas, Bansko, and central Sofia often display English-language options. Withdrawal limits typically range from 400 to 800 lev per transaction depending on the machine operator. International cards bearing Visa, Mastercard, or Maestro symbols function at most ATMs operated by major banks including UniCredit Bulbank, DSK Bank, United Bulgarian Bank, First Investment Bank, and Raiffeisenbank Bulgaria. ATM networks outside provincial capitals thin noticeably. Villages in the Rhodope Mountains, Strandzha Nature Park, and sections of the Stara Planina may have no machines within 30 kilometers. Withdrawal fees vary by home bank agreements, not Bulgarian machines. Most Bulgarian ATMs do not charge additional fees to foreign cardholders, though some privately operated machines in airports or shopping centers may add 5 to 10 lev per transaction, disclosed on-screen before confirmation.
Credit and debit cards see acceptance primarily in establishments targeting tourists or serving urban populations. Hotels rated three stars and above in Sofia, Plovdiv, Varna, and Burgas generally accept international cards. Chain supermarkets including Kaufland, Lidl, Billa, and Fantastico process card payments throughout their networks. Restaurants in Sofia's city center and Plovdiv's Old Town accept cards with increasing regularity, though establishments outside pedestrian tourist zones often operate cash-only. The Bulgarian National Bank reported in 2021 that point-of-sale terminals numbered approximately 180,000 nationwide, concentrated heavily in Sofia, which holds roughly one-third of all terminals despite having 15 percent of the population. Contactless payment functions at most modern terminals, with a tap limit of 50 lev before PIN entry becomes mandatory. Fuel stations along major motorways accept cards reliably. Rural petrol stations, particularly on secondary roads in Vidin, Sliven, or Yambol provinces, may not process cards or may impose minimum purchase requirements of 30 to 50 lev. Markets including the Women's Market in Sofia, the central market in Plovdiv, and the fish market in Burgas operate exclusively in cash. Vendors at Rila Monastery, Bachkovo Monastery, and Belogradchik Fortress sell souvenirs, candles, and refreshments for cash only. Museums and archaeological sites managed by the National Institute of Archaeology with Museum split between cash and card acceptance. The Ancient Theatre of Plovdiv ticket office accepts cards. Perperikon accepts only cash as of 2023. Taxi drivers rarely accept cards even in Sofia, though bolt and taxi apps process digital payments. Church donations, public restrooms, and municipal parking meters require coins.
Currency exchange offices operate throughout Bulgaria under licenses from the Bulgarian National Bank. Licensed offices display their permit number visibly. Exchange rates posted must show both buy and sell prices. Offices cluster near border crossings, airports, central railway stations, and pedestrian shopping streets. Rates vary significantly between operators. Bank branches including DSK Bank and UniCredit Bulbank offer exchange services during banking hours, typically weekdays 9:00 to 17:00, with rates less favorable than dedicated exchange offices but more reliable than kiosks. Exchange offices near major tourist sites in Nesebar Old Town, the Alexander Nevsky Cathedral in Sofia, and Golden Sands resort consistently offer rates 3 to 7 percent worse than offices on side streets three blocks away. Sofia Airport Terminal 2 houses multiple exchange desks; the office past security in the departures area typically provides better rates than those in the arrivals hall. Exchanging euros yields better rates than exchanging US dollars, British pounds, or other currencies due to the lev's euro peg. Many exchange offices accept only euro and US dollar notes. Exchanging damaged, torn, or heavily marked banknotes often results in refusal or rates reduced by 10 to 20 percent. The Bulgarian National Bank itself operates no public exchange service. Commission-free exchange offices earn revenue through the spread between buy and sell rates rather than flat fees. Offices advertising "no commission" do not necessarily provide better effective rates than those charging 1 to 2 percent commission with tighter spreads.
Bulgarian banks open weekdays generally between 9:00 and 17:00, with many branches closing between 12:30 and 13:30. Saturday hours appear at selected branches in Sofia and Varna, typically 9:00 to 13:00. Sunday opening is rare and limited to airport branches. International wire transfers into Bulgaria typically arrive within two to four business days for SEPA transfers from eurozone banks, longer for SWIFT transfers from outside Europe. Bulgarian banks charge receiving fees ranging from 10 to 25 lev for incoming international transfers depending on the institution and transfer amount. Opening a Bulgarian bank account as a non-resident requires a passport, proof of address in Bulgaria such as a rental contract or utility bill, and sometimes a document certifying tax residency in another country. Procedures and requirements differ between banks. UniCredit Bulbank and Raiffeisenbank Bulgaria maintain English-speaking staff at major branches and market specifically to expats and foreign investors. Processing takes from same-day to two weeks depending on documentation completeness. Some banks require in-person visits to multiple branch appointments. Monthly maintenance fees for basic accounts range from zero to 8 lev. Dormancy fees of 5 to 10 lev per month may apply if no transactions occur for six months. Debit cards tied to accounts typically cost 5 to 15 lev annually. Bulgarian banks generally do not offer accounts to tourists or short-term visitors without proof of extended stay.
Mobile network coverage in Bulgaria operates across three primary carriers: Vivacom, A1 Bulgaria, and Yettel Bulgaria, formerly Telenor Bulgaria until a 2022 rebrand. All three maintain 4G LTE networks covering approximately 95 percent of the population according to 2023 data from the Communications Regulation Commission, the national telecom regulator. Geographic coverage differs from population coverage. The Rhodope Mountains, particularly areas around Trigrad Gorge and villages south of Smolyan, experience patchy or absent mobile signal. The Stara Planina sees reliable coverage along the main E772 road through the Shipka Pass but signal drops in valleys and on hiking trails more than 2 kilometers from roads. Coverage along the Black Sea coast between Varna and Burgas remains consistent, extending inland roughly 10 kilometers before becoming unreliable in agricultural areas. The Danube Plain north of Pleven has functional coverage in towns but long signal-free stretches on rural roads between settlements. 5G networks launched in Sofia, Plovdiv, Varna, and Burgas starting in 2020, with continued expansion along major motorways. The Communications Regulation Commission reported in early 2023 that 5G covered approximately 30 percent of the population, concentrated almost entirely in the five largest cities. Vivacom historically held advantages in rural coverage due to legacy infrastructure from its predecessor, the state telecom monopoly BTC. A1 Bulgaria emphasizes urban data speeds. Yettel positions itself in the mid-market. Independent testing by the Bulgarian Telecommunications Company users association in 2022 found minimal practical difference in urban coverage but gave Vivacom higher marks in mountain regions.
