Early warning signals of cities in Shandong Province began.

Police uniforms are made of iron and velvet, and so are ID cards. With the badge, you can verify the specific person, which is unique.

Why do you want to cooperate with the badge? Because of the large number of public security police, only provinces and police types can assign their own numbers, not the whole country, and the Ministry of Public Security assigns numbers separately. Therefore, there are duplicate numbers between provinces and between provinces and the Ministry of Public Security, which can only be distinguished by badges.

The police intelligence alarm number of public security organs and state security organs is six digits, and the alarm number at the beginning of 00 is generally the alarm number of the office. 0 1-99 starts with the city code. For example, Jinan, Shandong, 0 1, Qingdao, Shandong, 02, but with the increase in the number of police recruits, the city code, or other figures, is not necessarily the beginning. For example, Qingdao, Shandong Province has an alarm number beginning with 1 1.

This is an early warning signal from the heads of ministries and agencies.

Note that the official police alarm numbers are all pure numbers without letters.

Police cadets' warning signs generally start with X, some with S or "learning J", some with letters in the middle, and some with nameplates instead of warning signs. Because there is no uniform regulation, this place is different.

Other non-police, general public security starts with ba, auxiliary police, auxiliary police, TQ for secret service, ZA for public security, etc. These are not uniform, and they vary from place to place.

To sum up, police officers are all pure numbers, and those with letters are not police officers.
