My products are not custom-made. I don't know where to find GTIN or MPN.
Make sure your products are manufactured. Then try to contact the manufacturer or GS1 to get the correct GTINs. Since GTIN is international, Google can check its validity. So please don't make up your GTINs. Wrong formats definitely result in disapproved products.
If you can't have them, please contact us for support to tell Google that your identifier exists but you don't have them in place (set GTIN, MPN to blank). This way, your products will still get approved (provided they're not caught into other warnings) with limited performance.
