Requirements
Who can register a .js.cn?
- Individuals as well as companies and organisations outside China can register a .js.cn domain name.
- The Chinese registry CNNIC requires real-name identity verification. As the registrant, you must provide the real name of a natural person.
- The registrant's name must match the name on the ID document or company document exactly. For a company, this includes the legal form, such as LTD.
- If you live outside China, your name must not contain special characters such as ä, ü, ö or é. With characters like these, CNNIC can't verify your passport and the application will fail.
- Does a company's contact person have special characters in their name? Then you can have the domain registered by another person within the company whose name doesn't contain such characters and who is willing to be verified.
- You must comply with CNNIC's registration rules and dispute resolution policy and with Chinese domain name regulations.
- You may not register or use a domain name that CNNIC considers to be in breach of the Chinese constitution or laws. Think of harming national security, or spreading rumours, pornography, gambling or violence.
- If your website's web server is located in mainland China, you need a valid ICP number from the Chinese ministry MIIT. This is only possible if you have a branch in China.
- When you apply, you confirm that your details are genuine, accurate and complete and that you've read CNNIC's rules. You're responsible for the content of your website yourself.
Additional details for registration
- You state whether you're registering as an individual or as a company.
- You provide the number and type of the registrant's ID document, for example a passport, a Chinese ID card or a business licence.
- If you're registering as a company or organisation, you provide the name of a responsible person. This person doesn't need to be listed on the company document.
Documents
- Individuals outside China send a scan or photo of their passport or ID card. A driving licence isn't accepted, and the registrant's name must be on the document.
- Companies and organisations outside China send a scan of their business licence or an extract from the trade register. A copy of the responsible person's passport or ID card is also required.
- Individuals in mainland China send a copy of their Chinese ID card, not a passport.
- Companies in China send page 1 of the company document, preferably the business licence. A copy of the contact person's ID card or passport is also required.
- Residents of Hong Kong, Macau and Taiwan can use a travel or residence permit for the mainland. Foreign nationals can use a permanent resident ID card. For the residence permits and that ID card, both the front and back are required.
- When you register, you provide documents as JPEG files of no more than 1 MB.
- A signed declaration, known as the Letter of Commitment, is no longer required.
Good to know when registering
- CNNIC checks every application manually, even if you've been approved before. So the registration isn't completed straight away.
- If your documents haven't been received after 8 days, the registration will fail.
- CNNIC may interrupt or suspend the use of your domain name if you don't comply with the rules. CNNIC and the registrar can't be held liable for this.
- You can request a domain certificate. For this, you need the domain name and the registrant's phone number.
Transfer
Transferring a .js.cn
- Transferring a domain also requires identity verification of the registrant, with a copy of the ID document or business licence.
- You need a signed request from the registrant before the transfer is started.
- The domain must not have a lock. You can check this in the WHOIS. If the domain is locked, the registrant can ask the current registrar to remove the lock.
- The domain must be more than 60 days old, otherwise the transfer will be refused.
- The expiry date must be more than 15 days in the future, otherwise the transfer will be refused. So start the transfer in good time.
The transfer code
- You need a transfer code to transfer a domain.
- The registrant or the administrative contact requests the code from the current registrar.
- Check beforehand that the code is correct. With an incorrect code, the transfer will fail.
Owner
Change of registrant
Change of registrant
- The new registrant must provide a copy of their ID document or passport. A company provides its business licence.
- Documents for a change of registrant can be JPG, PNG, GIF or JPEG, up to a maximum of 1 MB.
- A change of registrant isn't processed immediately. Allow for some waiting time.
- If the domain is registered in the name of a trustee service, you can transfer it to a registrant of your own. Transferring it to a trustee service isn't possible.
Renewal, cancellation and quarantine
- After being restored from quarantine, the domain is initially inactive. It becomes active again once the registrar has set up the nameservers again.
