Overview

Error 6000 is a common inventory file upload error that Amazon sellers encounter when the first row of their inventory file template has been altered or corrupted. This row contains essential template type and version information that Amazon's system needs to process the file correctly. Understanding how to prevent and resolve this error can save sellers significant time when managing their product listings through flat file uploads.

Key Points / What Sellers Need to Know

• Template header row is critical — The very first row of any Amazon inventory file template contains the template type and version number, and this row must remain exactly as Amazon provides it for successful processing.
• Modifications cause rejection — Even small, accidental changes to the first row will trigger Error 6000, causing the entire file upload to fail regardless of how accurate the rest of the data is.
• Fresh templates solve most issues — Downloading a new copy of the appropriate inventory file template from Seller Central is often the fastest path to resolving this error.
• Spreadsheet and text editor formatting differs — The way template type and version data is structured in the first row depends on whether you are using a spreadsheet application or a plain text editor, and each has specific formatting requirements.

How the Error Occurs

Amazon's inventory file processing system reads the first row of every uploaded file to identify which template type is being used and what version it corresponds to. Template types include categories like Books, Music, Supplies, and many others, each with their own specific column structures and data requirements. When the system cannot match the first row to any known template type or version number in its records, it returns Error 6000 and halts the upload entirely. This commonly happens when sellers accidentally edit, delete, or overwrite the contents of the first row while working on their product data in the rows below. It can also occur if a seller copies data from one template version into an outdated or mismatched template file.

How to Fix Error 6000

Resolving this error requires restoring the correct header information in the first row of the inventory file. The most reliable method is to download a fresh copy of the appropriate template from Seller Central and transfer your product data into it, being careful not to alter the first row in the process. If you prefer to correct the existing file, compare the first row of your file against the first row of a freshly downloaded template and make sure they match exactly. For sellers using spreadsheet software like Microsoft Excel or Google Sheets, the template type should appear in cell A1 and the version number should appear in cell A2 of the first row. For those editing inventory files with a plain text editor, the template type and version number should be separated by a single tab character on the first line of the file, with no extra spaces or characters added.
