On barcode lookup
Type the 13 digits under the bars on an On box. The article number, such as 3MG10071430, is a different code.
Old and new On article numbers
On uses two forms of article number. Older pairs carry two digits, a dot and five digits, such as 59.98986 for a Cloud 5 in All Black. Newer pairs carry an 11-character code: on.com sells the Men's Cloudrunner 3 in Black | Ivory as 3MG10071430, and the address of that page names the model part, 3mg1007. Our catalogue holds the Cloudmonster 3 Black as 3MG10051043 and the Cloudmonster 1 Black Grey as 3MF30740553.
The two forms can name the same kind of shoe, so a search by article number depends on which form the label shows. The barcode avoids that question: one number names one colour in one size.
Barcodes we hold
On 9 November 2026 we held 33,440 On barcodes for 2,987 On styles, and for most of those styles we hold the size run: the median style has 13 sizes, the middle half 8 to 14. Another 1,227 On styles (29%) are in our catalogue with no barcode yet, so a real barcode of one of those styles returns no result. Of the barcodes, 99% are 13-digit EAN-13 and 1.1% are 12-digit UPC-A.
Company blocks
The first 7 digits of the 13-digit form are the company block, and the 5 largest of the 98 On blocks hold 96% of the On barcodes we hold.

What a match proves
A match shows that the number is an On barcode in our data and names its style and size: check them against the article number and the size on the box and inside the shoe, such as 3MG10051043 on the On Running Cloudmonster 3 Black. A match does not show that the pair is original, because a copied box can carry a real barcode, as the guide on what a barcode check can tell you explains.
