How to fix: Unsupported value due to restrictions: GTIN [gtin]

Use a GTIN that is not restricted; the current value has not been released for use yet by GS1

Some GTIN (Global Trade Item Number) values fall within a restricted range that has been reserved for future use. Values that you submit for the GTIN [gtin] attribute must not fall within this range.

If the product category of your product requires a GTIN as a unique product identifier, then you must submit the correct manufacturer-assigned GTIN for each product. If a GTIN is not required, you may leave the GTIN [gtin] attribute without a value.

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