How to explain a patent without a patent number?

The reasons why a patent has no patent number are as follows:

1, the invention application is not long, so you can't find it.

2. The utility model patent or the appearance patent didn't get the certificate during the examination, so the external network won't be made public, and you can't find this either.

After the application was accepted, you didn't pay the application fee. You just got the patent application number, not the patent number. No such patent can be found on the extranet.
