How to Check a Samsung Warranty by IMEI or Serial Number

Open Settings → About phone, or dial *#06#. A dual-SIM Samsung phone usually displays IMEI 1 and IMEI 2; the warranty form may require only the primary IMEI. You can also record the Serial Number shown in About phone.

Compare the identifier in the operating system with the label on the box before submitting it. A mismatch deserves investigation, particularly when buying a used phone or accepting inventory from a supplier.

Open Samsung Vietnam’s electronic warranty checker, select the mobile-device group, and enter the requested IMEI or serial number. Complete the verification step to view the available activation, expiration, and extended-warranty details.

Compare the returned model, electronic activation date, warranty expiration date, and any extended coverage with the device and invoice. If a date differs from the receipt, contact Samsung and provide valid proof of purchase.

A missing result does not necessarily mean the phone is counterfeit. The IMEI may have been typed incorrectly, the device may come from another market, or the electronic warranty record may not yet be synchronized.

A warranty record does not prove that every component is original, that the software has never been modified, that the phone is free of a Google account lock, or that the IMEI is clear on every carrier blacklist. For a used Samsung phone, inspect the hardware, compare the phone and box, review the invoice, and complete a factory-reset and activation test with the seller.

When buying used or receiving a lot, put this term on your checklist: get the right code → read Coverage → match the model → then pay. See also IMEI vs serial and by-model checks.

If you live in spreadsheets, pair this with the Batch IMEI Checker for Excel.

A common mistake is calling a device “clean” just because Coverage returns OK. Coverage does not replace an on-device Activation Lock check, and it does not report carrier blacklists. Separate layers reduce the risk of taking unsellable units.

Knowing the term prevents wrong conclusions from a single Coverage line. Return to the full glossary, browse comparisons, or open BatchIMEI for bulk checks.
