If you've read an FIR or a cyber crime notice that mentions Sections 66C and 66D of the Information Technology Act, 2000, together, you're not alone in finding them confusing. They are often clubbed in the same complaint, but they punish two distinct kinds of conduct, and the difference matters a great deal for how a defence is built.
What Section 66C Punishes: Identity Theft
Section 66C deals with the fraudulent or dishonest use of another person's identifying feature — this includes electronic signatures, passwords, or any other unique identification feature such as Aadhaar number, PAN, biometric data, or login credentials.
In simple terms, this section is triggered when someone uses your identity markers — not necessarily to pretend to be you in a conversation, but to access or misuse systems, accounts, or benefits meant for you. Common real-world examples include:
- Someone using a stolen Aadhaar number to open a bank account or take a loan
- Unauthorized use of another person's login credentials to access an email or banking portal
- Cloning a SIM card using someone else's identity documents
Punishment under Section 66C extends to imprisonment of up to three years and a fine which may extend to one lakh rupees.
What Section 66D Punishes: Cheating by Personation Using a Computer Resource
Section 66D is narrower and specifically targets cheating by personation — meaning the offender pretends to be someone else (or a fictitious person) using a computer resource or communication device, in order to deceive the victim into parting with money, property, or sensitive information.
Typical examples include:
- Creating a fake profile impersonating a bank official, army officer, or matrimonial match to defraud a victim
- Sending phishing messages pretending to be from a legitimate company or government body
- Impersonating a person's known contact on WhatsApp or social media to solicit money
The punishment here can extend to imprisonment of up to three years and a fine which may extend to one lakh rupees, similar to 66C, but the ingredients of the offence are different — deception and personation are central, not merely unauthorized use of an identifier.
Key Differences at a Glance
| Aspect | Section 66C | Section 66D |
|---|---|---|
| Core Act | Unauthorized use of identity feature | Pretending to be someone else to cheat |
| Intent required | Fraudulent or dishonest use | Cheating through personation |
| Typical evidence | Login logs, KYC misuse records | Chat records, fake profile screenshots, payment trail |
| Common pairing | Often with BNS cheating sections | Often with BNS cheating and forgery sections |
Why Both Sections Are Often Invoked Together
In many FIRs, both sections appear because the same set of facts can satisfy both ingredients — for instance, a fraudster who steals someone's identity documents (66C) and then uses a fake profile built on that identity to cheat a third party (66D). Investigating officers often apply both sections to keep the widest possible net of charges available, even where the actual conduct may only clearly satisfy one.
What This Means If You're Named in Such a Case
If you are the accused, the specific section invoked significantly affects your defence strategy:
- Under 66C, the defence often focuses on whether you had authorized access or consent to use the identifying feature
- Under 66D, the defence often turns on whether there was genuine intent to deceive, or whether the personation element is even established
If you are the complainant or victim, correctly identifying which section applies to your facts helps ensure the FIR is registered accurately and the investigation proceeds on the right footing — a poorly drafted complaint can weaken your case later at trial.
Bailability and Legal Process
Both Section 66C and 66D offences are cognizable and bailable in most circumstances, though this can change depending on what other sections of the Bharatiya Nyaya Sanhita are added to the same FIR (such as cheating, forgery, or criminal breach of trust, some of which carry higher sentences and can affect bail considerations).
