Macau

Macau, a Special Administrative Region of China, is identified internationally by the ISO codes MO (alpha-2) and MAC (alpha-3), along with the .mo country-code top-level domain (ccTLD) for local web addresses. Its international calling code is +853, required when dialing into the territory from abroad. The official currency is the Macanese Pataca (MOP), denoted as MOP$ in financial and business contexts. These identifiers serve practical roles in telecommunications, domain registration, and cross-border commerce, particularly within Macau’s unique legal framework and its status as a global gaming and tourism center. Correct use of these codes ensures reliable connectivity and proper administrative handling in regional and international transactions.
