How to Check Sony Warranty by IMEI/Serial

Xperia phones have an IMEI; TVs, cameras, headphones, and speakers use model/serial. Do not enter a Xperia IMEI into a TV form or the other way around. Find the codes in Settings, on the device label, and on the box.

Open https://baohanhdientu.sony.com.vn/tracuu/, choose the product group, then enter the model and Serial shown on the product. The Vietnam form primarily uses Serial; for Xperia phones, use the IMEI to match the handset with its box and settings.

Sony model numbers often include a market suffix. If the Vietnam page does not accept the serial, the unit may belong to another region or the data may not be synced yet. Confirm with Sony before drawing conclusions about origin or coverage rights.

Besides IMEI, check the Google account, display, battery, camera, water resistance after repairs, and whether the phone can be reset. An expired warranty does not describe the full condition of the device.

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.
