How to fix: Unsupported value (restricted) [gtin]

Use a GTIN that's not in the restricted range (prefixes: 02, 04, or 2)

One of the GTIN (Global Trade Item Number) values in your product data is invalid because it has a prefix that’s restricted for special purposes and internal systems. These codes start with “2”, “02”, or “04” and should not be submitted as values for the gtin attribute.

To fix this error, use a GTIN that's not in the restricted range.

For more information about the validation of GTINs, refer to the GTIN Validation Guide edited by GS1.
