Requirements
Who can register a .zj.cn?
- Individuals as well as companies and organisations both inside and outside China can register a .zj.cn domain.
- The registry CNNIC requires real-name verification. As the registrant or contact person, 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, including the legal form, such as LTD.
- If you're not from China, your name must not contain special characters such as ä, ü, ö or accented letters such as é. Otherwise CNNIC can't check your ID document and the application will fail.
- If a company registers the domain, it can be put in the name of another employee whose name has no special characters. That person must be willing to provide an ID document, though.
- You must comply with CNNIC's rules, the Chinese regulations on domain names and CNNIC's dispute resolution policy.
- The domain must not breach Chinese law. Examples include harming national security, spreading rumours, pornography, gambling or violence, violating religious policy or defaming others.
- If the web server is located in China, you need a valid ICP number from the Chinese ministry MIIT. You can only get one if you have a business presence in China.
- You must provide genuine, correct and complete documents and declare that you've read and understood CNNIC's rules.
- You're fully responsible yourself if the domain is suspended because you break the rules. CNNIC and the registrar are not liable for this.
Additional details for registration
- You state whether the registrant is an individual or a company or organisation.
- You provide the number and type of the registrant's ID document, for example a passport, a Chinese identity card or a company registration.
- Companies and organisations provide the name of a responsible person. This person doesn't need to be listed on the company document.
- If the web server is located in China, you provide a valid ICP number.
Documents
- Individuals outside China send a scan or photo of their passport or identity card. A driving licence isn't accepted and the registrant's name must appear on the document.
- Companies and organisations outside China include a business licence, company certificate or extract from the trade register. They also include a copy of the responsible person's passport or identity card.
- Individuals and contact persons from mainland China send a copy of their Chinese identity card, not a passport.
- Companies in China also include a copy of page 1 of the company certificate, for example the deed of incorporation or business licence. The business licence is preferred.
- If you're from Hong Kong, Macau or Taiwan, mainland travel permits and residence permits are also accepted, as is the foreigner's residence card. For residence permits and the residence card, you send both the front and the back.
- You provide documents for a registration in JPEG format, up to 1 MB per document.
- A signed declaration, 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 your domain won't be active straight away.
- If the required documents aren't received within 8 days, the registration fails.
Transfer
Transferring a .zj.cn
- To transfer a domain, you need a transfer code. Without the correct code, the transfer fails.
- The domain must not have a lock, such as a registrar lock or HOLD status. You can see this in the WHOIS, and as the registrant you can ask for the lock to be removed.
- The domain must be older than 60 days, otherwise the transfer will be refused.
- The expiry date must be more than 15 days in the future. So start in good time, not just before the domain expires.
- You need a signed request from the registrant before the transfer is started.
- For a transfer, the registrant must be known. Real-name verification may need to be carried out again.
The transfer code
- A transfer code is required to transfer a domain.
- You get the code from your current registrar. The registrant or the administrative contact can request it.
- Check that the code is correct before you start the transfer, otherwise it will fail.
Owner
Change of registrant
Change of registrant
- A change of registrant requires a copy of the new registrant's ID document or passport. For companies, this is the business licence.
- You provide documents as JPG, PNG, GIF or JPEG, up to 1 MB per document.
- A change of registrant isn't processed immediately, so expect some waiting time.
- If the domain was registered in the name of a trustee service, you can transfer it to your own registrant. The other way round, from your own registrant to a trustee service, isn't possible.
Renewal, cancellation and quarantine
- After a domain is restored, it's inactive at first until the nameservers have been set up again. After that, it becomes active again automatically.
