I was told to replace the first two digits of the GTIN with 10 vs. 00 and use the 00 to start the UPC only. When I put in the GTIN as 10xxxxxxxxxxxx, the system tells me it's not valid. How do I move forward?&nbsp;</P> Wed, 15 Sep 2021 14:30:22 GMT https://community.1worldsync.com/t5/Ask-A-Question-for-Item/INCORRECT-GTIN/m-p/1841#M447 bdavis4209 2021-09-15T14:30:22Z https://community.1worldsync.com/t5/Ask-A-Question-for-Item/INCORRECT-GTIN/m-p/1852#M448 <P>Hello and thank you for reaching out to us.&nbsp; It sounds like you are running into an issue with your check digit (14th digit).&nbsp; Please see below and let me know I you have any other questions.</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="CommunityJedi22_0-1631724868038.png" style="width: 999px;"><img src="https://community.1worldsync.com/t5/image/serverpage/image-id/598i05FA18DE0EB02C01/image-size/large?v=v2&amp;px=999" role="button" title="CommunityJedi22_0-1631724868038.png" alt="CommunityJedi22_0-1631724868038.png" /></span></P> <P>&nbsp;</P> Wed, 15 Sep 2021 16:55:15 GMT https://community.1worldsync.com/t5/Ask-A-Question-for-Item/INCORRECT-GTIN/m-p/1852#M448 CommunityJedi22 2021-09-15T16:55:15Z
