Unsupported value: reserved or restricted [gtin]

What Google requires

A barcode from the globally issued ranges

GS1 reserves parts of the numbering space. Barcodes beginning with 2, 02 or 04 (read off the zero-padded 13-digit form) are for in-store and variable-measure use, the scale label on cheese, a shop's internal SKU barcodes, and coupon ranges are for coupons. None of them identify a product globally, so Google refuses them even though the check digit is correct.

What happens if you do not

A refusal that survives every re-check you do

The merchant verifies the barcode, finds it scans fine at the till, resubmits it, and it is refused again, because the till and Google are answering different questions. The till asks whether the barcode is well formed; Google asks whether it identifies this product to the rest of the world. In-store codes usually enter a feed through a POS system that generated them, which means the same fault repeats across a whole section of the catalogue.

How to fix it by hand

Find the real GTIN, or declare there is none

• Check the prefix on the zero-padded form before concluding anything: a 12-digit UPC-A starting 98 normalises to 098, which is legitimate. Not everything that starts with a suspicious digit is restricted.
• For branded goods, the manufacturer issued a real GTIN; it is on the packaging or in the supplier data. The in-store code in your feed is a stand-in that has to be replaced.
• For own products that only ever had an internal code, treat them as barcode-less: brand plus MPN, or identifier_exists: no.

Which of our checks apply

Two checks apply, read from the scanner's registry

The prefix logic reads the zero-padded 13-digit form, so legitimate barcodes that merely look suspicious are not flagged. This distinction is the part almost no other tool makes.

The quicker way

Let the scan find them

The free scan reads every barcode's prefix the way GS1 defines it and names the products carrying in-store or coupon ranges, before Google refuses them. The scan to identify errors is free and shows every finding before you pay anything. You only pay for the fix.
