Phone Lost or Stolen in India? Block It and File a Complaint

Vaksy Legal Desk · Law as of 6 October 2026 · 6 min read

Report the loss to the police and keep a copy, get a duplicate SIM for your number, then submit the block request on the Sanchar Saathi (CEIR) portal with the police report and an identity proof. The portal says a reported handset is blocked within 24 hours and then cannot be used on any network across India.

This guide follows the order the government portal gives, and explains the police step using the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) and the Bharatiya Nyaya Sanhita, 2023 (BNS).

The steps, in order

  1. Note your IMEI. The CEIR page says the IMEI “is written on the mobile packaging box” and can be found on the mobile bill or invoice. It also says “Dual SIM phones will have two IMEI numbers.”
  2. Report to the police and keep a copy. The portal's first instruction is “File a report with the police, and keep a copy of the report.” The next section covers how.
  3. Get a duplicate SIM. The portal says to “Get a duplicate SIM Card for the lost number from your telecom service provider”, naming Airtel, Jio, Voda/Idea, BSNL and MTNL as examples. It calls this essential, because the OTP for the block request is sent to that number.
  4. Mind the 24 hour note. The portal adds that, under TRAI's regulation, “SMS facility on re-issued SIMs is enabled after 24 hours of SIM activation.” Since the OTP is sent to that number, my reading is that you may have to wait before the form can be completed.
  5. Gather documents. The portal says “a copy of police report and an Identity Proof must be provided. You can also provide the mobile purchase invoice.”
  6. Submit the block request. Use the request form for blocking the IMEI of a lost or stolen phone on the portal, or the Sanchar Saathi mobile app. You are given a Request ID, which the portal says can be used to check the status of the request and to unblock the IMEI later. Save it.
  7. Wait for the block. A reported handset “will be blocked for usage in Indian telecom network within 24 hours.” The CEIR page adds that once blocked, it cannot be used on any network across India.

The portal names two routes: the form on its website, or through State Police. If, after you submit, the portal shows a message that a request already exists for your IMEI and mobile number by State police, it says that means the request already exists in the system through State police.

Filing the police report: what section 173 says

Section 173(1) BNSS covers information about a cognizable offence. It says such information, “irrespective of the area where the offence is committed”, may be given orally or by electronic communication to an officer in charge of a police station. The words zero FIR do not appear in the section, but this is the rule that label is usually used for.

Stolen versus lost

BNS section 303(1) describes theft as a person “intending to take dishonestly any movable property out of the possession of any person” without consent, moving it to do so. The First Schedule to the BNSS lists theft under section 303(2) as cognizable, and snatching under section 304(2) as cognizable. It also has a separate line for theft where the value of the property is less than 5,000 rupees, listed as non-cognizable. For non-cognizable offences, section 174 provides for the informant to be referred to the Magistrate.

The portal covers phones that are “lost/stolen” and says only to file a report with the police. The texts used here do not describe what a report of a merely lost phone looks like, so ask the station to record what happened and give you a written copy, which is what the portal needs.

What blocking does, and does not do

If the phone is found

Unblock only if the phone has been found and is in your possession. The portal says you must first report to local police “that it is found”, then submit the unblocking form. If the blocking request went through State Police, you must approach State police for the unblocking request.

Also check connections in your name

Sanchar Saathi lets a subscriber “check the number of mobile connections taken in his/her name” and report connections “either not required or not taken by the subscriber”. If someone uses your number or accounts to harass you, see Being Cyberstalked or Harassed Online? Your Legal Options

What to keep

Questions people ask

Can I block a lost phone without a police report?

The Sanchar Saathi procedure for the website form starts with filing a police report and says a copy of the police report and an identity proof must be provided. The portal also names a second route, through State Police.

How long does blocking take after I submit the form?

The portal says a reported handset will be blocked for use in the Indian telecom network within 24 hours. Once blocked, it cannot be used on any network across India.

Can I report the theft at any police station?

Section 173(1) of the Bharatiya Nagarik Suraksha Sanhita, 2023 allows information about a cognizable offence to be given to an officer in charge of a police station irrespective of the area where the offence is committed, orally or by electronic communication.

What if I find the phone after blocking it?

Report to local police that it is found, then submit the unblocking form on the portal. If the blocking request was registered through State Police, you must approach State Police to register the unblocking request.
