Macau numbering plan & how to dial
Macau uses a closed numbering plan under country code +853: subscribers are reached with a single 8-digit number after the country code, with no separate area code to dial.
With 90% internet penetration, Macau is covered by 3 major carriers — CTM, SmarTone Macau, China Telecom Macau. VoIP is permitted and regulated by Office for the Development of Telecommunications and Information Technology (GDTTI). IVR prompts, SMS copy, and business hours here should account for the local language (Cantonese, Portuguese) and currency (MOP).
Asian markets range from fully liberalised to licensed-only VoIP, so compliant routing and correct local caller ID have an outsized 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.

FAQ
Calling Macau — frequently asked questions

A recognisable +853 number tends to get answered more often than an unfamiliar international one — that's the main reason to present local caller ID in Macau. Unknown foreign numbers are frequently screened or ignored, which can quietly suppress answer rates on outbound sales and support calls.
