my country adopts the automatic acquisition of copyrights. Software and other works automatically obtain copyright protection from the moment they are created, without authorization from administrative agencies, so there is no such thing as a copyright authorization number.
This is where copyright differs from other intellectual property rights such as patents and registered trademarks.
In order to avoid unnecessary disputes in the process of exercising rights in the future and strive for the convenience of resolving disputes, some copyright owners, including computer software copyright owners, will choose to register their copyrights.
Registration handled by the Copyright Protection Center only has the effect of evidence and has no other special effects.
So if you find the registration number, it can already correspond to the corresponding work, and there is no need to look for the authorization number.
