API commands

Please find in the following a set of the most commonly used standard API commands in order to register, modify, renew, and transfer a domain name.

Domain Registration

The .net.cn registry changed its policies and relaxed the restrictions for .net.cn registrations. Under the new rules, companies and individuals outside China are allowed to register Chinese domain names again.

The following requirements for registrants outside China are effective as of Monday, September 3, 2012:

  • For individuals outside of China:
    • Applicants need to submit a scan or photo copy of an official document that could prove the identity of the registrant: CNNIC is only accepting passports 2019/11. All documents provided as a proof of identity must feature the name of the registrant.
    • A signed Letter of Commitment is no longer required!
  • For companies and organizations outside of China:
    • Applicants need to submit a scan or photo copy of their business license / business certificate or an excerpt from the commercial register
    • The contact ID (Handle) needs to provide a contact name for the responsible person in the company/organization. A copy of passport or ID is not required.

  • Once you enter the order in the system, you need to send an email to cn-audit@rrpproxy.net to let them know you have done so (you can send one email with a list of the registrations you submitted.
