.mo Regulations

Requirements & Information

Why register .mo?
Macau, also spelled Macao, is a city in the region of the People's Republic of China. With a population of about 650,000, it is the most densely populated region in the world.

Macau was also a former colony of the Portuguese Empire and remined under the colony rule until 1999, when it was transferred to China. Macau is now a special administrative region of China and it maintains separate governing and economic systems from mainland China under the principle of "one country, two systems. If you conduct business from within Macau , it is time to register a .MO domain extension. Registering a dot 'MO' country code extension (top level domain name) will increase credibility for your business across the globe. Why? Country-code domains are meant specifically for businesses that do business within a particular country--in this case, Macau The .com domain (and other generic TLDs) are not targeted and that online space is saturated--and you likely already have the .com for your business.

Extend your brand presence with a more relevant, shorter domain--a ccTLD that differentiates you from competitors. Identify yourself as an official Macau business owner and give your clients and constituents more confidence as they interact with you online. Country code domains also help you rank higher in local search results
