San Marino has no airport. The nearest commercial airport is Federico Fellini International Airport in Rimini, Italy, located approximately 25 kilometers from the City of San Marino. This airport receives seasonal flights from European cities and limited year-round service. Bologna Guglielmo Marconi Airport lies roughly 135 kilometers northwest and offers broader international connections. Visitors arriving at either airport continue by car, bus, or taxi into San Marino.
San Marino has no railway. The Rimini–San Marino Railway operated from 1932 to 1944 when Allied bombing during World War II destroyed sections of the line. The line was never rebuilt. The nearest functioning railway station is Rimini railway station, approximately 24 kilometers from the capital, which connects to Italy's national rail network.
Bonelli Bus Group operates direct bus service between Rimini railway station and the City of San Marino. Buses depart multiple times daily with increased frequency during summer months. The journey takes approximately 50 minutes. Tickets are purchased at the station or from the driver. San Marino Bus Company provides internal service connecting the nine municipalities, with routes centered on the capital and Borgo Maggiore.
San Marino lies entirely within Italian territory. The country shares a 37-kilometer border with Italy, specifically with the Emilia-Romagna region and a smaller section with the Marche region. No border checkpoints exist. Vehicles and pedestrians move freely between Italy and San Marino without passport control or customs inspection, though technically the border is an international boundary between two sovereign states.
The euro is the official currency, used since 2002. San Marino is not a member of the European Union but adopted the euro through a monetary agreement with the European Union, formalized in 2000. The country issues its own euro coins with distinct Sammarinese designs on the national side, minted in limited quantities. These coins circulate throughout the eurozone but are collected due to their rarity and command premiums above face value outside normal commerce.
San Marino mints its euro coins at the Italian State Mint in Rome under contract. Annual mintage is capped by agreement with the European Union. The 2002 first series depicted the three towers of Mount Titano, the Basilica of San Marino, and the Statue of Liberty in Piazza della Libertà across different denominations. Designs change periodically. Collectors seek these coins, but they function as legal tender throughout the eurozone.
Italian euros dominate everyday transactions. Sammarinese euro coins represent a small fraction of currency in circulation within the country itself. ATMs dispense Italian-minted notes and coins. Banks exchange foreign currency to euros at standard eurozone rates. Credit and debit cards are widely accepted in hotels, restaurants, and shops in the City of San Marino and Borgo Maggiore, though smaller establishments in less-visited municipalities may prefer cash.
San Marino issues its own postage stamps, another source of collector interest and state revenue. The Philatelic and Numismatic Office of the Republic of San Marino handles sales. Stamps are valid for international postage and are recognized by the Universal Postal Union, which San Marino joined in 1877. The postal service operates independently from Italy's Poste Italiane, though Italy handles international mail routing under bilateral agreement.
Italian is the sole official language. The Romagnol dialect is spoken in informal contexts, particularly among older residents, but Italian dominates all official communication, education, commerce, and media. Visitors who speak Italian encounter no language barrier. English is understood in tourist-facing businesses in the capital and Borgo Maggiore, though less commonly in smaller municipalities.
San Marino uses the same electrical standard as Italy: 230 volts at 50 hertz with Type F and Type L plugs. Type F is the Schuko plug with two round pins and grounding clips. Type L is the Italian-specific plug with three pins in a row. Adapters for these plug types are necessary for devices from countries using different standards. Most modern electronics accept 230-volt input, but travelers should verify their device specifications.
The country follows Central European Time, UTC+1 in winter and Central European Summer Time, UTC+2 from the last Sunday in March to the last Sunday in October. This matches Italy and most of continental Europe. Clocks advance one hour in spring and retreat one hour in autumn on the same dates as the European Union observes.
Mobile phone service is provided by San Marino's state-owned operator, San Marino RTV, and private operators. San Marino has its own country calling code, +378. Italian mobile networks also function within San Marino due to the small territory and proximity to Italian cell towers. Travelers with Italian SIM cards or EU roaming agreements generally connect without issue. Those from outside the EU should verify international roaming rates before use, as San Marino is not part of the European Union and may incur separate roaming charges depending on the carrier agreement.
Internet access is available in hotels, restaurants, and cafes in the City of San Marino and Borgo Maggiore. Public Wi-Fi is less common in smaller municipalities. Mobile data networks cover the territory. The country has invested in fiber optic infrastructure, and connection speeds in urban areas are comparable to those in northern Italy.
