According to ALLCITYCODES.COM, the area code of Costa Rica is +506, which was adopted in 1997 when the country switched to the ITU-T E.164 numbering system. The code is divided into two parts: ‘+’ and ‘506’. The ‘+’ indicates that the number is international and the ‘506’ identifies the country as Costa Rica. In Costa Rica, telephone numbers are usually eight digits long and are divided into four parts: a two-digit area code, a three-digit exchange code, a two-digit line number and an optional one-digit service code. Area codes indicate the geographic region of the phone number and are used to route incoming calls to their respective locations. Exchange codes identify specific local calling areas within each geographic region, while line numbers identify individual subscribers within each local calling area. Service codes are used to access special services such as voicemail or mobile networks. Costa Rica has seen advances in telecommunication services over recent years, with mobile phone penetration rates increasing rapidly across both rural and urban areas of the country. This has been driven by increased investment in infrastructure improvements as well as technological advancements such as 4G networks being rolled out in major cities across Costa Rica. As such, it is important for businesses operating within Costa Rica to ensure they are using the correct area codes when making calls within the country as well as when communicating with other countries around the world. Costa Rica is a democratic republic that has been governed by a multiparty system since 1949.

Costa Rica also has an independent judiciary system, which includes courts of first instance and appellate courts, as well as specialized courts for labor law, family law, and administrative law. The Supreme Court of Justice serves as the highest court in Costa Rica and has nine magistrates appointed by the Legislative Assembly. All citizens over 18 are eligible to vote in elections and referendums.
