Frequently Asked Questions

Can this site give me a UPC or GTIN?

No. It can explain formats and calculate check digits, but official identifier assignment must use the appropriate authorized process.

Does a valid check digit mean a barcode is legitimate?

No. It means only that the arithmetic check matches.

Are QR Codes replacing all barcodes in 2027?

No. The 2027 industry goal concerns increased retail ability to process newer 2D barcodes. Existing linear symbols are expected to coexist during transition.

What is a 3D barcode?

The phrase is informal. It often refers to a code physically engraved, etched or dot-peened into a surface. The encoded symbol itself may still be a two-dimensional Data Matrix.

Is RFID a barcode?

No. RFID uses radio communication. It can complement barcodes and may encode related identifiers.

Why does my barcode scan on my phone but not at work?

Different scanners support different symbologies and settings, and business applications may reject data even after the scanner decodes it.
