FIR vs NC – What is the Difference?
When you go to a police station with a complaint, police will register it either as an FIR or an NC— depending on the nature of the offence. This distinction is critical because it determines whether police can investigate your case immediately.
The Key Difference in One Sentence
An FIR is for serious (cognizable) crimes where police start investigating immediately and can arrest without a warrant; an NC is for minor (non-cognizable) offences where police cannot investigate or arrest without a magistrate's order.

Frequently Asked Questions
What is the main difference between FIR and NC?
The main difference is the type of offence and the police powers that follow. An FIR (First Information Report) is registered for cognizable offences — serious crimes where police can arrest without a warrant and must investigate automatically. An NC (Non-Cognizable Report) is for non-cognizable offences — minor infractions where police need a magistrate's permission to investigate or arrest. An FIR immediately sets the criminal law in motion; an NC does not.
Can police convert an NC into an FIR?
Yes. If new information emerges or investigation reveals that a cognizable offence is involved, an NC can be upgraded to an FIR. This is sometimes called 'converting NC to FIR'. A Judicial Magistrate can also order the registration of an FIR in an NC matter if the facts disclose a cognizable offence.
Is an FIR more serious than an NC?
In terms of seriousness of the underlying offence, yes — FIR is for cognizable (serious) offences, while NC is for non-cognizable (minor) ones. But from the complainant's perspective, an FIR is actually more powerful — it triggers immediate police investigation without needing a magistrate's approval. An NC complaint does not lead to automatic police action.
Which legal section governs FIR and which governs NC?
FIR is governed by Section 154 of the Code of Criminal Procedure (CrPC). NC (Non-Cognizable Report) is governed by Section 155 of the CrPC. Section 156 gives police the power to investigate cognizable offences. Section 155(2) requires a magistrate's order for police to investigate non-cognizable offences.
