A police officer should show his badge when he approaches you. If the badge is not visible, ask to see it. If you ask for the badge number, the officer should give it to you. If the officer refuses, you should report it to the police department.
If you are referring to a police officers badge, each officer is assigned a personal identification number. If you had a reason to find out or indicate who a particular officer is or was, you could give his/her badge number, and this number would identify the officer. In other words, the number connects to a name.
You ask the police officer, or they would've turned in their badge,you would see them without a badge.
If you have the badge number of a police officer, you can find out his or her name. Simply call the police station in that jurisdiction and ask for it.
It depends on state law. In the state where I live, it is legal to have a police badge as long as it is for collecting purposes only. Using a police badge for any other purpose such as impersonating an officer is illegal in federal and state law.
A retired police officer may keep and display their badge in most jurisdictions. The badge will not protect you, its the training that does.
I assume you want a badge number to make a complaint. Call the Police Department where the officer works. Then ask for Internal Affairs. They can find out which officer was working in the area where the problem occurred.
It is most commonly referred to as their 'badge' but it is also known as an officer's 'shield.'
HandcuffsAdded: Their badge and identification folder.
Not all Police Officers are issued badge numbers. However, most municipalities require Police Officers to provide specific identifying information to you about who they are in the event you need to file a formal complaint.
You would have to know what police department that police officer works for. Most agencies have the same type of numbering system. Assuming you know that information, just call that agency's non emergency phone number and talk to the dispatchers. Badge numbers are public record and they have to let you know who it belongs to, at least their last name. If your purpose was to file a complaint, or commend an officer, you can always do so by using the badge number instead of the name. They will figure it out and the process will continue as it should.
Could be the issued officer's initials and badge number.
In most cases, badges are issued to officers when they graduate from their basic police (academy) training. However, not all badge have numbers, and the officer's "badge number" may not have anything to do with his badge. Most officers do have a number associated with their law enforcement position, but this might be a state commission number, issued by the agency that certifies all officers in that state. In that case, the officer would keep the same number at any agency he worked within that state, even if he changed departments one or more times. The officer's number may be a serial number indicating his seniority among other governmental or department employees.
