When you file a complaint on the National Cyber Crime Reporting Portal, the portal generates an acknowledgement number at the end of the submission. That number is the reference for your matter until a First Information Report is registered. You use it to track the status of the complaint, to quote in follow-up with the police or your bank, and to ask for a copy of what you filed. It is not the same as an FIR number, and it is not the same as the reference the 1930 helpline gives you in a financial fraud; keep each of them separately, because a different office will ask for each.
Where the acknowledgement number comes from
The National Cyber Crime Reporting Portal, at cybercrime.gov.in, is the online route for reporting cyber offences. When you complete the form and attach the screenshots, bank statements or messages that support the complaint, the portal displays a complaint reference on screen and sends the same reference to the mobile number and email address you registered. That message is your proof that the complaint was filed on a particular date, and it is the acknowledgement number you quote from then on.
If you reported in person at a police station, the position is different. Under Section 173 of the Bharatiya Nagarik Suraksha Sanhita, 2023, which replaced Section 154 of the Code of Criminal Procedure, 1973 from 1 July 2024, the officer must reduce your information to writing and give the informant a copy of the recorded information free of cost. That copy is the station-level acknowledgement, and it usually carries a station diary entry number or a complaint number rather than a portal reference. When people search for a cyber crime complaint acknowledgement number they often mean one or the other, and it helps to know which document you are holding before you start making enquiries.
How to check status with the acknowledgement number
The portal keeps a status facility where you enter the acknowledgement number and the mobile number registered with the complaint. What you can see depends on how far the matter has moved: it may show as submitted, as assigned to a police unit, as converted into an FIR, or as closed. Take a screenshot of the status at each stage, because a dated record of how long the complaint stood still is useful if you later have to explain the delay to a senior officer or a court.
The national helpline 1930 handles online financial fraud and issues its own reference for the call. If money was taken, you should be tracking two references at once: the 1930 reference with your bank, and the portal acknowledgement number with the police. The two systems move at their own pace, and the answer to where your complaint has reached is often different in each. For the step-by-step version of that enquiry, see how to check a cyber crime complaint status online.
Acknowledgement number, FIR number and 1930 reference compared
| Reference | Who issues it | What it means |
|---|---|---|
| Portal acknowledgement number | The National Cyber Crime Reporting Portal | Your online complaint is registered and can be tracked; an FIR may or may not follow |
| Police station copy or diary number | The police station where you gave the information | Your written information has been received on a particular date |
| FIR number | The police station, on registering a cognisable offence | A criminal case has formally begun; it can be searched on the e-Courts and police systems |
| 1930 reference | The national cyber fraud helpline | A financial fraud report used by banks to try to freeze or trace the money |
None of these numbers substitutes for another, and quoting the wrong one is a common reason a follow-up goes nowhere. If you are unsure which you have, read the message or receipt carefully: a complaint reference known only to the portal is not an FIR number, and a bank reference from 1930 is not a police number.
What to do if you have lost the number
- Search the email inbox and the SMS inbox of the mobile number you registered, including the spam or promotions folder; the portal sends the acknowledgement there at the time of filing.
- Log in to the portal with the same registered mobile number and open the complaints or status section, where past acknowledgements are listed against your number.
- If you filed at a police station, go back to the same station with a written request asking for the number of your complaint or a copy of the recorded information, which you are entitled to receive free of cost.
- Keep the date, the subject matter and the amount involved ready, because officers search older complaints by these details when a reference is missing.
What the acknowledgement number does not do
An acknowledgement number proves that a complaint exists. It does not by itself register an FIR, it does not freeze the money in the fraudster's account, and it does not guarantee that anything will be recovered. Registration of an FIR for a cognisable offence is a separate step, taken either by the police on their own or on the direction of a Magistrate. Treat the number as the beginning of a trail rather than the end of the problem, and keep following the status.
It is also worth understanding that a portal complaint about a hacked account, a fake profile or online abuse does not always need to become an FIR before the police act, but a serious offence should end in one, and you are entitled to press for it. The route from complaint to FIR depends on the nature of the offence and the evidence, which is why the same acknowledgement number can lead to very different outcomes in two similar-looking cases.
If the complaint does not move forward
If the status does not change for weeks, send a written reminder to the officer handling the complaint, quoting the acknowledgement number, and keep a copy. If nothing happens even then, you can send your information to the Superintendent of Police under Section 173 of the BNSS, 2023, which was Section 154(3) of the CrPC, 1973 before 1 July 2024, who may either investigate the matter or direct a subordinate officer to do so.
Beyond that, a Magistrate can be asked to direct an investigation where the police have not registered a case, under Section 175(3) of the BNSS, 2023, which corresponds to the old Section 156(3) of the CrPC. These are technical steps and the factual record decides the result, so keep every acknowledgement, receipt and screenshot together.

Common mistakes that make the number useless
The most frequent mistake is to file a second, slightly different complaint instead of following up the first. Two live complaints about the same transaction confuse the police unit, split the evidence and make it look as though the account is inconsistent. If you need to add material, write to the officer handling the existing complaint and quote the acknowledgement number, rather than starting again on the portal.
- Filing with a mobile number you will not keep, so the status cannot be checked and the SMS is lost.
- Attaching screenshots without the transaction reference, date or the fraudster's account details, which makes the complaint hard to link to a bank record.
- Waiting weeks before telling the bank, by which time the money has moved through several accounts.
- Assuming the portal complaint has frozen the account, when only the bank and the 1930 process can attempt that.
A complaint that is precise about the amount, the date, the platform and the beneficiary is far easier to act on than a long narrative. Keep the acknowledgement number on the same page as those details, and the follow-up becomes a matter of quoting a reference rather than retelling the story.
Keep these details next to the number
- The exact date and time you filed, and the office or portal through which you filed.
- The acknowledgement number, the 1930 reference if any, and the FIR number once it is registered.
- Copies of the transaction records, chat messages, emails and screenshots you attached.
- The name and designation of the officer, and the police station or unit, once the complaint is assigned.
- A running note of every follow-up call, visit and written reminder, with dates.
A well-kept file of this kind is what turns an acknowledgement number into a case that actually moves. If the matter is not progressing, you can request a free consultation with the chamber to have the papers reviewed.
