What is one of the necessary pieces of information to complete a citation?

To complete a citation, the necessary piece of information includes the date of birth. This detail serves to accurately identify the individual being cited, especially if there are multiple people with the same name. Including the date of birth helps prevent confusion and ensures that the citation is directed to the correct person, facilitating proper legal procedures.

While other pieces of information like a manager's name, insurance number, or witness statements may be relevant in specific contexts, they are not essential for the fundamental purpose of issuing a citation. The date of birth stands out as critical for identification purposes within law enforcement documentation, thereby making it a necessary component in the citation process.
