What is bulgarian zip code?

Bulgarian zip codes consist of five digits and are used to identify a specific location or address within the country. The first two digits are used to identify the region, while the remaining three digits indicate the specific postal district. There are 28 regions in Bulgaria, each with its unique two-digit code. The Bulgarian postal service is known as Bulgarian Posts. Major cities in Bulgaria, such as Sofia, Plovdiv, and Varna, have multiple postal codes due to their larger size and higher population density.
