In the address “V. Garibaldi u. 4. III/21”, the Roman numeral V indicates District V. “Garibaldi u.” means Garibaldi Street (“u.” =”utca” = street). 4 is the house number, III is the floor number, and 21 is the apartment number. The two digits in the middle of the four-digit postal code also identify the district (thus the postal code 1054 indicates a
