Requirements
Who can register a .sx.cn?
- Individuals, companies and organisations both inside and outside China can register a .sx.cn domain name.
- CNNIC requires mandatory real-name verification: the domain must be registered in the name of a real person who proves their identity. This also applies to transfers and registrant changes.
- The registrant's name must exactly match the name on the ID document or company certificate, including 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. Otherwise CNNIC can't verify your passport and the application will fail.
- If your name contains such characters and you're registering for a company, you can register the domain name in the name of a colleague whose name has no special characters and who is willing to be verified.
- You must comply with CNNIC's rules and the Chinese domain name regulations, and confirm that you have read and understood them.
- You must provide genuine, accurate and complete details and documents, and comply with the rules for the content of websites on the domain name.
- You may not use the domain name for anything that CNNIC considers to be against Chinese law, such as subverting the state, discrimination, pornography, gambling, violence, defamation or spreading rumours.
- If the web server is in mainland China, you need a valid ICP number from the Chinese ministry MIIT. You can only get one if the registrant has an office in China.
- You are fully responsible if the domain name is suspended because the rules have been broken. CNNIC and the registrar are not liable for this.
Additional details for registration
- You state whether the registrant is a person or a company or organisation.
- You state the type of ID document, such as a passport, identity card or company registration, and its number.
- Companies and organisations provide the real name of a responsible person. This person doesn't need to appear on the company certificate.
Documents
- Individuals outside China send a scan or photo of their passport or identity card showing the registrant's name. A driving licence is not accepted.
- Companies and organisations outside China send an extract from the commercial register or a business licence, plus a copy of the responsible person's passport or identity card.
- Individuals from mainland China send a copy of their Chinese identity card, not a passport.
- Chinese companies send page 1 of their company certificate, preferably the business licence, plus a copy of the responsible person's ID document.
- Special travel or residence permits apply to residents of Hong Kong, Macau and Taiwan. For residence permits and the residence card for foreigners, a copy of both the front and the back is required.
- When registering, supply documents as a JPEG file of no more than 1 MB.
- A signed declaration is no longer required.
Good to know when registering
- Every application is checked manually by CNNIC, even if you've been approved before. This means registration isn't instant.
- If CNNIC doesn't receive your documents within 8 days, the registration will fail.
- After registration, you can request a domain certificate. You'll need the domain name and the registrant's phone number for this.
Transfer
Transferring a .sx.cn
- To transfer a domain, the registrant's details are required. If CNNIC's identity check is needed, you supply an ID document and additional costs may apply.
- You need a signed request from the registrant before the transfer is started.
- 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, otherwise the transfer will be refused. So make sure you start in good time.
- The domain name must not be locked. You can check this in the WHOIS. If it is locked, the registrant can ask the current registrar to remove the lock.
The transfer code
- You need a transfer code to transfer a domain.
- The registrant or administrative contact requests the code from the current registrar.
- Check that the code is correct before you start the transfer, otherwise it will fail.
Owner
Change of registrant
Change of registrant
- The new registrant must supply a copy of their ID document or passport or, for a company, the business licence.
- Supply documents for a registrant change as a jpg, png, gif or jpeg file of no more than 1 MB.
- A registrant change isn't processed instantly, because CNNIC checks the details.
- You can switch from a former trustee service to your own registrant, but you can't switch to a trustee service.
Renewal, cancellation and quarantine
- After being restored from quarantine, the domain name is initially inactive, with no nameservers. As soon as nameservers are set again, it automatically becomes active again.
