Buying a Used Phone? Check the IMEI Before You Pay in 2025

Before you hand over cash for a second-hand phone, dial #06# on the handset to display its IMEI number, then verify that number free on the government CEIR Sanchar Saathi portal. If the IMEI shows up as blacklisted, blocked, or duplicate, the phone is likely lost or stolen and could stop working on every network in India. A one-minute check protects your money and keeps you out of a police case over a device someone else reported missing. This is the single most important step a buyer can take, and from 22 October 2025 the law also puts a duty on the seller. Below is exactly how to run the check yourself, what the new 2025 rules now demand of resellers, what to do if an IMEI comes back blocked, and how to block your own phone the day it goes missing. ===== Step 1: Check the IMEI yourself before paying ===== Every phone has a unique 15-digit IMEI (International Mobile Equipment Identity). Dual-SIM phones have two. The government CEIR (Central Equipment Identity Register) keeps a central database of IMEIs that have been reported lost, stolen, or blocked. You can query it free in under two minutes. Do this in front of the seller, with the actual handset in your hand, before any money changes hands: - On the phone you want to buy, open the dialler and type #06#. The IMEI number (or two numbers, for a dual-SIM phone) appears instantly on screen. Cross-check it against the IMEI printed on the box and under the battery or on the SIM tray. - Open the government verification page: https://ceir.sancharsaathi.gov.in/Device/CeirImeiVerification.jsp - Enter the 15-digit IMEI, complete the captcha, and enter your own mobile number to receive a one-time password (OTP). - Enter the OTP to see the device status returned by CEIR. - Read the result. A clean device shows as valid. A device flagged as blacklisted, blocked, duplicate, or already reported stolen is a red flag. Walk away and do not pay. If the box IMEI, the #06# IMEI, and the tray IMEI do not all match, treat the device as suspect. Tampered or re-flashed IMEIs are a known trick for moving stolen handsets.

The Telecommunications (Telecom Cyber Security) Amendment Rules, 2025, which came into force on 22 October 2025, introduced a duty called Resale Device Scrubbing. In plain terms, any entity that deals in the resale or refurbishment of devices must scrub every device's IMEI number through a centralized database of blacklisted IMEIs before it sells that device. The official purpose is to protect genuine purchasers and to help law enforcement trace stolen equipment.

So a legitimate refurbished-phone shop or online reseller is now expected to have already cleared the IMEI before it reaches you. That is good news, but it does not remove your own duty of care. A roadside seller or a stranger on a classifieds app is not a monitored reseller, and many handovers happen with no scrubbing at all. Your own #06# check remains the only guarantee.

The same 2025 amendment also created a separate system called the Mobile Number Validation (MNV) platform, which targets the SIM and number layer rather than the device. That is a different topic with its own guide: see https://righttoinformation.wiki/mobile-number-validation-platform-mnv-dot-2025-india . This article stays focused on the device and its IMEI.

If CEIR flags the IMEI as blacklisted or stolen, take these steps:

1. Do not buy the phone. A blocked IMEI can be barred from every Indian network, so the device may become a paperweight after the sale.
2. Do not assume the seller is innocent or guilty from the result alone. A genuine owner sometimes blocks a phone and forgets to unblock it after recovery. But the risk and the paperwork fall on you once you have paid, so the safe choice is to refuse the deal.
3. Keep a record. Screenshot the CEIR result with the IMEI visible. If you have already paid and only checked afterwards, this is your evidence.
4. If you suspect the phone is stolen, you can report it. Tampering with an IMEI is itself an offence under the Telecommunications Act, 2023, and is treated seriously by the authorities.
5. If you have already lost money to a seller who passed off a stolen or IMEI-tampered phone, you can also raise a telecom-services complaint: https://righttoinformation.wiki/file-trai-telecom-complaint-2026 .

The same CEIR Sanchar Saathi portal that buyers use to verify a phone is also where owners block a lost or stolen one. If your phone is stolen, blocking the IMEI bars the handset across networks, which is exactly the entry that later shows up when an honest buyer runs the check above.

To block your own device:

1. File a police report (FIR or a lost-property report) and keep the complaint number.
2. Go to the Sanchar Saathi CEIR portal and use the Block Stolen/Lost Mobile service, entering the IMEI, the police complaint details, and your contact number.
3. Note the request ID so you can track or later unblock the device if you recover it.

Block the SIM as well, because a thief can still misuse the number even when the handset is barred. See https://righttoinformation.wiki/block-lost-stolen-sim-card-india . It is also worth checking, on a separate day, whether any SIMs are registered in your name that you never asked for: https://righttoinformation.wiki/check-sim-misuse-tafcop-2026 .

Kashvi Pathak found a nearly-new flagship phone for less than half its market price on a classifieds app and met the seller at a cafe to inspect it. Before paying, she dialled #06# on the handset, read off the 15-digit IMEI, and entered it on the CEIR verification page using the OTP sent to her own number. The status came back as blocked / reported lost. She also noticed the IMEI on the retail box did not match the one on screen. She declined the deal on the spot and kept a screenshot. A week later a relative who skipped the check on a similar bargain found the phone went dead on every network within days because the real owner had blacklisted it. The free two-minute check saved Kashvi both the money and the trouble. ===== Common mistakes to avoid ===== - Paying first, checking later. The CEIR check takes two minutes; run it before money changes hands, not after. - Trusting only the box IMEI. Always dial #06# on the live handset and compare all three: screen, box, and SIM tray.

1. Assuming a refurbished-shop sticker means it is cleared. The 2025 scrubbing duty applies to monitored resellers, but verify anyway; a sticker is not proof.
2. Ignoring a duplicate-IMEI result. Duplicate or mismatched IMEIs are a classic sign of a re-flashed stolen device.
3. Forgetting the SIM. Blocking the phone is not the same as blocking the number.

Dial **#06# on the phone's dialler and the 15-digit IMEI appears on screen at once. Dual-SIM phones show two numbers. It is also printed on the retail box and usually under the battery or on the SIM tray. Check that all three match.

Yes. The check runs on the CEIR portal at https://ceir.sancharsaathi.gov.in/Device/CeirImeiVerification.jsp , which is part of the Department of Telecommunications Sanchar Saathi platform. There is no fee. You only need the IMEI, a captcha, and your own mobile number for the OTP.

It means the device has been reported lost or stolen, or otherwise flagged, in the central CEIR database. Such a handset can be barred from every network in India, so it may stop working after you buy it. Do not pay for a phone with a flagged IMEI.

For monitored resellers and refurbishers, yes. The Telecommunications (Telecom Cyber Security) Amendment Rules, 2025, in force from 22 October 2025, require entities dealing in resale or refurbished devices to scrub each device's IMEI against the blacklisted-IMEI database before resale. A private individual selling their own phone is not a monitored reseller, so always run your own check.

Yes. Tampering with or altering an IMEI is an offence under the Telecommunications Act, 2023, and is treated seriously by the authorities. A handset with a mismatched or re-flashed IMEI should be avoided.

The IMEI check covers the device. The Mobile Number Validation (MNV) platform, created by the same 2025 amendment, covers the SIM and mobile-number layer instead. They solve different problems. See the dedicated MNV guide: https://righttoinformation.wiki/mobile-number-validation-platform-mnv-dot-2025-india .

Keep all proof: the CEIR screenshot, the seller's details, and the payment record. Approach the seller for a refund first. If the device appears stolen, you can report it to the police, and you may also raise a telecom complaint at https://righttoinformation.wiki/file-trai-telecom-complaint-2026 . You can separately review SIMs issued in your name at https://righttoinformation.wiki/unknown-mobile-numbers-in-my-name-sanchar-saathi-tafcop .
