What is a Domain Name? And the Obligation to Declare According to Law
A domain name is a website's address on the Internet, used to identify the online identity of a business, organization, or individual. In the context of Vietnamese law, a domain name linked to a sales website must be declared with the Ministry of Industry and Trade to ensure compliance with e-commerce regulations.
Common Types of Domain Names
Vietnamese National Domain Name (.vn)
Managed by the Vietnam Internet Network Information Center (VNNIC). This is the most common type of domain name and is strictly protected by Vietnamese law.
International Domain Names
Domain names such as .com, .net, .org, .info... are registered through international domain name providers. International domain names must still be declared if used for commercial purposes in Vietnam.
Subdomains
Are child branches of the main domain, such as shop.domain.com. Subdomains used to introduce products or conduct commercial transactions are also subject to declaration.
Why Declare Your Domain Name?
Declaring your domain name helps:
- Meet legal requirements for e-commerce under Decree 52/2013/ND-CP and Decree 85/2021/ND-CP
- Increase the credibility of the website with consumers and partners
- Reduce the risk of administrative penalties, suspension of website operations, or being listed in the warning list of the Ministry of Industry and Trade

Cases Where Websites Need to Declare Domain Names
Online Sales Commercial Websites
Websites that introduce products and have ordering, payment, and user account creation functions must declare their domain names to avoid violating regulations.
Websites Providing Automated Services
Including transaction platforms, transport service booking applications, food and beverage, hotels, online auctions, payment intermediaries, digital asset rentals...
Websites with Integrated Commercial Features but Not Directly Selling
Websites that introduce products or services but link to external platforms for transactions may still need to be declared if they are owned by businesses with clear business operations.
Websites Using International Domain Names
Even if the domain name is not .vn, if the website targets customers in Vietnam or conducts transactions with Vietnamese people, declaration is still mandatory according to regulations.

Should I Declare a Website That Is Not Working or Incomplete?
Only declare when the website is working and has full functionality. If the website is incomplete or only for display without transactions, the business can wait until it is complete to do so.
