Sao Tome and Principe Address Format
Santomean addresses follow the Portuguese convention: recipient, street name with house number after it (Avenida/Rua X, nº Y), then city and country. There is no postal code, and a P.O. Box (Caixa Postal) line is very common. District names are generally not written. Limited public documentation of formal addressing rules beyond the national operator's practice.
