The special ticket issued by the supplier can be found in the electronic tax bureau, but it can't be found when the invoice is authenticated.

1. Invoice information is not synchronized in time: the data synchronization between the electronic tax bureau and the authentication system will be delayed, resulting in the failure to update the latest invoice information during authentication. It is recommended to try authentication again later to ensure that the data has been synchronized.

2. Incorrect information input: In the process of invoice authentication, you will be asked to input some necessary information, such as invoice code and invoice number. Please carefully check whether the information entered is consistent with the actual invoice to ensure that there is no input error.

3. Abnormal invoice information: sometimes the invoice is abnormal, such as the invoice is invalid and has been authenticated. These situations can also lead to the inability to find invoice information during authentication. You can contact the supplier to verify the validity of the invoice and consult the relevant tax authorities for more help.
