Requirements
Who can register a .tw.cn?
- Individuals and companies both inside and outside China can register a .tw.cn domain name.
- The registry CNNIC requires a real-name verification: the registrant must be a real, natural person who can identify themselves with an identity document.
- The registrant's name must exactly match the name on the identity document or company registration document, including the legal form, such as LTD.
- If you're from 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 registration, transfer or change of registrant will fail.
- If the name of a company's contact person contains special characters, you can provide another person within the company who has a standard name and is willing to submit an identity document.
- You must comply with CNNIC's rules and Chinese domain name regulations, including the rules on the content of websites on the domain.
- You may not register or use the domain for content that CNNIC considers to violate the Chinese constitution or laws. Think of harming national security, discrimination, pornography, gambling, violence, defamation or spreading rumours.
- 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 business presence in China.
- You're fully responsible yourself if the domain is suspended because you don't follow the rules. CNNIC and the registrar aren't liable if use of the domain is interrupted.
Additional details for registration
- You state whether you're registering as an individual or as an organisation.
- You provide the real name of a natural person. For a company, this is a responsible contact person, who doesn't need to appear on the company document.
- You provide the type of identity document or registration document, along with its number. Examples include a passport, a Chinese identity card, a business licence or a certificate with a unified social credit code.
Documents
- As an individual outside China, you send a scan or photo of your passport or identity card in JPEG format. Your name must be shown on it. A driving licence isn't accepted.
- As a company or organisation outside China, you send a copy of your business licence, company certificate or an extract from the trade register. You also provide a passport or identity card of the contact person.
- As an individual from mainland China, you send a copy of your Chinese identity card, not your passport.
- As a company in China, you send page 1 of the company certificate, preferably the business licence, plus an identity document of the contact person.
- If you're from Hong Kong, Macau or Taiwan, you can use a mainland travel permit or residence permit, among other documents. A permanent residence card for foreigners is also possible.
- For the residence permits for residents of Hong Kong, Macau and Taiwan and for the permanent residence card for foreigners, you must send both the front and the back.
- You provide documents for registration as a JPEG file of no more than 1 MB.
- A signed declaration is no longer required.
Good to know when registering
- Every registration is checked manually by CNNIC. This also happens if your details have already been approved before.
- If the required documents still haven't been received after 8 days, the registration fails.
- When registering, you must confirm that you're providing correct and complete documents and that you've read and understood CNNIC's registration rules.
- You can request a domain certificate. For this, you need the domain name and the registrant's phone number.
Transfer
Transferring a .tw.cn
- To transfer a domain, you need a signed request from the registrant.
- Registrant details are mandatory for a transfer. A new real-name verification may also be required, with the corresponding identity document.
- Make sure the domain isn't locked. If the domain is locked, the registrant can ask the current registrar to remove the lock.
- The domain must be older than 60 days, otherwise the transfer will be rejected.
- The expiry date must be more than 15 days in the future, otherwise the transfer will be rejected. So start the transfer in good time.
The transfer code
- A transfer code is required to transfer a domain.
- The registrant or the administrative contact requests the code from the current registrar.
- Check that you have the correct code before you start the transfer, otherwise it will fail.
Owner
Change of registrant
Change of registrant
- For a change of registrant, you provide a copy of the new registrant's passport, identity card or business licence.
- Documents for a change of registrant can be a JPG, PNG, GIF or JPEG file of no more than 1 MB.
- A change of registrant isn't processed instantly, but takes some time.
- If the domain is registered in the name of a trustee service, you can move it to your own registrant. Moving it to a trustee service isn't possible.
Renewal, cancellation and quarantine
- If you restore a domain from quarantine, it remains inactive until nameservers have been set again. After that, it automatically becomes active again.
