How to check the alarm number

1. First, log in to "National Police Information System of the Ministry of Public Security" to inquire about official police types and numbers.

2. Secondly, check with the local public security bureau. The alarm number is the police's "identity card", and an alarm number will follow a policeman until he retires.

Finally, remember the number on the left and the name of the province on the right, and go to the public security organ where the police are located to check the alarm number.
