BadGtin(20017112, InvalidData)

Description

This error occurs when a GTIN (Global Trade Item Number) is submitted but does not follow the correct format. A GTIN must always be numeric and have the correct length depending on the GTIN type (e.g., GTIN-8, GTIN-12, GTIN-13, or GTIN-14).

Cause

• The GTIN contains invalid characters (e.g., letters or special symbols).

• The GTIN has the wrong length (too short or too long).

• The GTIN does not comply with the standard for valid barcodes.

Resolution

1. Ensure that the GTIN consists of digits only.

2. Verify that the length is correct:

   • GTIN-8 → 8 digits

   • GTIN-12 (UPC) → 12 digits

   • GTIN-13 (EAN) → 13 digits

   • GTIN-14 → 14 digits

3. Enter a valid GTIN before submitting the product.

Example

• Valid: GTIN = "7312350333374" (13 digits, valid EAN)

• Valid: GTIN = "012345678905" (12 digits, valid UPC)

• Invalid: GTIN = "B11E905" (contains letters, invalid format)

• Invalid: GTIN = "12345" (too short)
