California Penal Code 148.9 PC makes it a crime to knowingly provide false identifying information to a police officer during a lawful detention or arrest.
This offense is typically charged as a misdemeanor and can result in jail time, fines, and a criminal record.
Many people are charged under this law after providing false names, dates of birth, or other identifying details to avoid arrest, conceal a warrant, or delay an investigation.

What Is Penal Code 148.9 PC?
Penal Code 148.9 PC prohibits a person from falsely identifying themselves to a peace officer with the intent to evade proper identification or avoid legal consequences.
To convict someone under this statute, prosecutors must prove:
-
you falsely represented your identity or provided fictitious information
-
the information was given to a peace officer
-
you were lawfully detained or arrested
-
you intended to evade identification or the legal process
-
you knew the person was a police officer performing official duties
If any of these elements are missing, the charge may not apply.
When Are You Required to Identify Yourself?
In California, you are not always required to identify yourself to police.
However, you must provide accurate identifying information when:
-
you are lawfully detained
-
you are under arrest
If you are not lawfully detained, you generally have the right to remain silent and decline to identify yourself. The law only applies when a detention or arrest is lawful.
What Counts as False Identification?
False identification includes more than just giving a fake name.
Examples include:
-
providing a false name
-
giving a fake date of birth
-
using another person's identity
-
presenting a false address
-
providing incorrect identifying documents
Any false information intended to mislead law enforcement may trigger charges under PC 148.9.
Examples of Violations
Example 1
A person is stopped by police and gives a false name because they have an outstanding warrant. This may result in charges under Penal Code 148.9.
Example 2
An individual provides a fake date of birth during a lawful detention to avoid identification. This may qualify as false identification.
Example 3
A person uses another individual's identity during an arrest to avoid being charged. This may result in additional charges beyond PC 148.9.

Legal Defenses to PC 148.9 Charges
Several defenses may apply depending on the facts of the case.
No Lawful Detention or Arrest
The law only applies if the detention or arrest was lawful.
If police lacked legal grounds to detain you, the charge may not apply.
Lack of Knowledge
You must know that the person you are speaking to is a police officer.
If the officer was undercover or did not identify themselves, this may be a defense.
No Intent to Evade
The prosecution must prove that you intended to avoid identification.
If the false information was accidental or not intended to mislead, the charge may fail.
False Accusation
In some cases, individuals are wrongfully accused of providing false information.
A defense attorney may challenge the credibility of the officer's testimony.
Constitutional Violations
If law enforcement violated your rights, evidence may be suppressed, weakening the case.
