I’m having a hard time figuring out the relationship between Qobuz SKUs and
UPCs. By SKU, I’m referring to the 13-character component at the end of the URL (sometimes only digits, but sometimes with letters mixed in). This is also repeated a bunch of times in the page source and sometimes referred to as an ID there.
In some cases like https://www.qobuz.com/us-en/album/a-dave-brubeck-christmas-dave-brubeck/0008940834102 (which just redirects to an artist page for me now), the SKU looks like it’s the first 11 digits of an GTIN-12 code (i.e. without the check digit), left-padded with two zeros. Feeding it to Check digit calculator - Services | GS1, I get 089408341021, which leads me to https://www.discogs.com/release/14330931-Dave-Brubeck-A-Dave-Brubeck-Christmas.
Then there’s https://www.qobuz.com/us-en/album/in-rainbows-radiohead/0634904032432, which only has a single zero on the left. Per What is a GTIN, I think that it can’t be the first 13 digits of a GTIN-14 since those aren’t supposed to start with a zero. It could be GTIN-13 6349040324320 without the check digit or GTIN-12 634904032432, but I don’t see any results online for either of those.
And then there are URLs like https://www.qobuz.com/us-en/album/the-dark-side-of-the-moon-pink-floyd/xggxq5w5dmljb that are mostly letters. Maybe there’s a way to map the letters to digits, or maybe something entirely different is going on.
I’m pretty stumped, so if there are any UPC experts out there with more insights or Qobuz experts who know of a way to consistently get UPCs, I’d love to hear from them.
