Requirements
Who can register a .bj.cn?
- Individuals as well as companies and organisations outside China may register a .bj.cn domain name.
- The registry CNNIC applies a mandatory identity check: as the registrant, you must provide the real name of a natural person and prove your identity.
- The registrant's name must match the name on the ID document or company registration certificate exactly, including the legal form, such as B.V. or Ltd.
- If a foreign registrant's name contains special characters such as ä, ü, ö or é, CNNIC can't verify the passport and the application will fail. Use a name without such characters.
- Are you a company and does your contact person have special characters in their name? Then you can provide another employee whose name has no special characters and who is willing to submit an ID document.
- You must provide real, accurate and complete details. You must also confirm that you have read and understood CNNIC's registration rules.
- You must comply with all rules on the content of websites under the domain name. You are fully responsible yourself if the domain is suspended because of violations.
- It is forbidden to register or use a domain name that, according to CNNIC, violates the constitution or national security of China, or harms the national honour and interests.
- Domain names that incite hatred or discrimination, violate religious policy, spread rumours or disrupt public order are also forbidden.
- The same applies to domain names that spread pornography, gambling, violence or terror, insult others or otherwise break Chinese law.
- 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.
Additional details for registration
- You indicate whether you're registering as an individual or as a company or organisation.
- You provide the type of ID document or registration certificate, along with the corresponding number.
- If you're registering as a company or organisation, you also provide the name of a responsible person within the organisation. This person doesn't need to be named on the company document.
- If you use the domain name for a website on a server in China, you also provide a valid ICP number.
Documents
- Individuals outside China submit a scan or copy of their passport or ID card showing the registrant's name. A driving licence isn't accepted.
- Companies and organisations outside China submit a copy 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.
- Registrants from China itself submit a copy of their Chinese ID card. Companies also include the first page of their company certificate, preferably the business licence.
- Registrants from Hong Kong, Macau and Taiwan can use certain travel and residence permits or a residence card for foreigners. For the residence permits and the residence card, both the front and back are required.
- When registering, you provide the documents as a JPEG file of no more than 1 MB.
- A signed letter of commitment is no longer required.
Good to know when registering
- CNNIC checks every application manually. This also applies if your contact details have already been approved before.
- If the required documents haven't been received after 8 days, the registration will fail.
- After registration, you can request a domain certificate. For this, you need the domain name and the registrant's phone number.
Transfer
Transferring a .bj.cn
- When you transfer a domain, the registrant's details are mandatory. An ID document is also required for CNNIC's identity check.
- If the identity check has to be carried out during the transfer, additional costs may apply.
- You need a signed request from the registrant before the transfer is started.
- Check beforehand that there's no lock on the domain. You can see this in the WHOIS. If there is a lock, the registrant can demand that it 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 the transfer in good time and not just before the domain expires.
The transfer code
- You always need a transfer code to transfer a domain.
- The registrant or the administrative contact requests the code from the current registrar.
- Check that the code is correct before the transfer begins. With an incorrect code, the transfer will fail.
Owner
Change of registrant
Change of registrant
- For a transfer of ownership, the new registrant must provide a copy of their ID document or passport. If it's a company, a copy of the business licence is required.
- You can provide the documents as a JPG, PNG or GIF file of no more than 1 MB.
- A change of registrant isn't processed immediately, so allow for some processing time.
- If the domain is currently registered through a trustee service, you can transfer it to your own registrant. The reverse, moving a domain to a trustee service, isn't possible.
Renewal, cancellation and quarantine
- Once the domain has been restored, it is initially inactive and no nameservers are set. As soon as the nameservers have been set again, the domain automatically becomes active again.
