Requirements
Who can register a .tj.cn?
- Individuals as well as companies and organisations inside and outside China can register a .tj.cn domain name.
- .tj.cn is subject to mandatory real-name verification by the Chinese registry CNNIC. You must prove your identity when you register, transfer a domain or change the registrant.
- The registrant's name must exactly match the name on the ID document or company registration document. For companies, this includes the legal form, such as LTD.
- If you're not from China, the full name on your passport or identity card must not contain special characters such as ä, ü, ö or é. Otherwise CNNIC can't complete the check.
- Registering as a company with this kind of name issue? Then the domain name can be registered in the name of another employee whose name has no special characters, provided that person is willing to submit proof of identity.
- You must accept CNNIC's registration rules and policies, including the Chinese rules on domain name disputes.
- You may not use a .tj.cn domain name for content that CNNIC considers to be in breach of Chinese law. This includes harming national security or unity, discrimination, cults, rumours, pornography, gambling, violence, terror or defamation.
- You're fully responsible yourself if the domain name is suspended because of a violation. CNNIC and the registrar are not liable if use of the domain name is interrupted.
- If the 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 business establishment in China.
Additional details for registration
- You state whether the registrant is an individual or a company or organisation.
- You provide the number of the registrant's ID document, plus the type of document, for example a passport, Chinese identity card or business licence.
- For a company or organisation, you give the real name of a responsible contact person. This person doesn't have to be listed on the company document.
- You must provide genuine, accurate and complete details and documents.
Documents
- Individuals outside China send a scan or photo of their passport or identity card in JPEG format. A driving licence is not accepted and the registrant's name must appear on the document.
- Companies and organisations outside China send a scan or copy of their business licence, company certificate or an extract from the trade register. A passport or identity card of the contact person is also required.
- Individuals from mainland China send a copy of their Chinese identity card, not a passport.
- Companies in China send a copy of the first page of the company certificate, preferably the business licence. Proof of identity of the contact person is also required.
- Residents of Hong Kong, Macau and Taiwan can use certain travel or residence permits. For the residence permits and the residence card for foreigners, both the front and back are required.
- A signed declaration is no longer required.
- Submit documents for registration as a JPEG of up to 1 MB.
Good to know when registering
- Every registration is checked manually by CNNIC, even if you've been approved before. This means the registration isn't completed straight away.
- If the documents haven't been received after 8 days, the registration fails.
- The registration is only completed once the documents have been received and checked.
Transfer
Transferring a .tj.cn
- When you transfer a domain, registrant details are required and real-name verification may be needed again.
- You need a valid transfer code. An incorrect code will cause the transfer to fail.
- The domain name must not have a lock. You can see this in the WHOIS, and as the registrant you can ask your current registrar to remove the lock.
- The domain name 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 the transfer in plenty of time.
- The transfer requires a signed request from the registrant.
The transfer code
- A transfer always requires a transfer code.
- The registrant or the administrative contact requests the code from the current registrar.
Owner
Change of registrant
Change of registrant
- For a change of registrant, the new registrant must provide a copy of their ID document or business licence.
- The change isn't processed straight away, because the documents are checked first.
- Documents for a change of registrant can be JPG, PNG, GIF or JPEG, up to 1 MB.
- Switching from a trustee service to a registrant of your own is possible. Switching to a trustee service isn't.
Renewal, cancellation and quarantine
- After an expired domain name has been restored, it's temporarily inactive until the nameservers have been set up again.
