XXXXXXXX
Macau uses a closed numbering plan under country code +853. You reach a subscriber with one 8-digit number after the country code. There is no separate area code to dial.
Carriers & language
Macau has 90% internet penetration. 3 major carriers cover it: CTM, SmarTone Macau, China Telecom Macau. VoIP is permitted and regulated by Office for the Development of Telecommunications and Information Technology (GDTTI). Plan IVR prompts, SMS copy and business hours around the local language (Cantonese, Portuguese) and currency (MOP).
Asia context
Asian markets range from fully open to licensed-only VoIP. Compliant routing and correct local caller ID have a big effect on answer rates.
Skipping the exit code
From the US you must dial 011 before the +853 country code to reach Macau.
Adding an area code that doesn't exist
Don't insert an area code for Macau: it's a closed plan, so +853 plus the 8-digit number is the whole address.
Ignoring the time difference
Before dialing Macau, check the local clock — it runs on UTC+8, and off-hours calls tend to go unanswered.
