Guide to Locating Your Devices Serial Number

March 28, 2026

Every electronics owner has faced this frustrating scenario: needing warranty service or device drivers, only to discover the serial number is nowhere to be found. Consider this your comprehensive manual for locating these crucial identifiers across various devices.

Serial numbers serve as a product's fingerprint—unique identifiers that manufacturers use to verify models, track production batches, and provide support services. Their location and format vary significantly across device types.

1. BHT Series and Barcode/QR Scanners: The Label Hunt

For BHT series products and scanning devices, the 16-digit serial number typically resides on the back panel. Look for a barcode or QR code—the alphanumeric sequence immediately following contains your identifier.

2. AT10Q Series: The Japanese Puzzle

These devices require assembling two components. First, locate the 10-digit number beneath the product name on the bottom grip. Then find the 6-digit sequence below the "MADE IN JAPAN" label. Combine them sequentially (e.g., "49XXXX-1XX1" + "8YYYY8" becomes "49XXXX1XX18YYYY8").

3. GT10B Series: Bottom Panel Clues

The solution lies on the underside label. The 16-digit serial number appears directly below the barcode, clearly printed for reference.

4. GT10Q Series: QR Code Decoding

Similar to AT10Q models, combine two segments: the 10-digit number under the product name and the 6-digit code beneath the QR label. Example: "496810-0XX1" + "40YYY2" becomes "4968100XX140YYY2".

5. IC Card Readers: Back Panel Identification

These follow the same pattern as barcode scanners—a 16-digit number positioned after the barcode on rear labels.

6. Software Products: Packaging Secrets

Software serial numbers typically appear on physical packaging rather than digital interfaces. Combine the 10-digit product code with the 6-digit "Serial No." (e.g., "496XXX-0YY1" + "0ZZZZ7" becomes "496XXX0YY10ZZZZ7").

Essential Verification Techniques

To ensure accurate serial number collection:

  • Consult product documentation first—many manuals specify identifier locations
  • Inspect all packaging materials before disposal
  • Use magnification tools for small or faded print
  • Photograph identifiers for digital records
  • Double-check sequences before submission
Beyond Warranty: Serial Number Applications

These identifiers serve multiple purposes:

  • Product activation for software and services
  • Authenticity verification through manufacturer databases
  • Lost device recovery assistance
Frequently Encountered Issues

Missing identifiers: First exhaust documentation and packaging reviews before contacting manufacturer support with purchase proof.

Input errors: Incorrect entries may block product activation, driver access, or warranty claims—always verify carefully.

Security considerations: While not containing personal data, serial numbers could facilitate counterfeit operations if shared indiscriminately.

Mastering these location techniques transforms serial number retrieval from a frustrating chore into a quick, systematic process. Proper identifier management ensures seamless access to support services throughout your device's lifecycle.
