Overview

Amazon sellers encounter Error 6000 when a bulk upload contains a numeric field that does not meet the platform’s non‑negative integer requirement. The validation fails during the file‑processing stage, returning the exact row and column where the problem lies. Fixing the issue quickly prevents delays in getting new SKUs or inventory updates live.

Key Points

• Error trigger — The system flags the feed as soon as it reads a value that is not a whole number ≥ 0, such as “‑2”, “4.7”, or “3 1/2”.
• Typical invalid entries — Decimals like “2.5”, fractions such as “1 3/4”, mixed text (“5 pcs”), and any negative sign will all generate the error.
• Allowed range — Only integers starting at zero (or one, depending on the field) are accepted; the value must contain digits exclusively, without commas, periods, or letters.
• Fields most affected — Quantity, handling time, number of items per case, and other inventory‑related attributes frequently enforce the non‑negative integer rule.
• Root cause of hidden characters — Copy‑pasting from external spreadsheets can embed invisible characters, trailing spaces, or locale‑specific decimal separators that the parser treats as invalid.
• Impact on bulk uploads — A single malformed entry can halt an entire batch of thousands of SKUs, forcing sellers to re‑process the whole file even if the mistake is isolated.
• Quick fix principle — Locate the flagged cell, replace the content with a proper integer, save the file in the required format, and resubmit; the error disappears once the value conforms.

How to Fix Error 6000

1. Locate the error reference — Open the upload report, note the row and column numbers Amazon provides (e.g., Row 152, Column B), and jump directly to that position in your spreadsheet.
2. Open the correct worksheet — If you work with multiple tabs (e.g., “Inventory” and “Pricing”), ensure you are editing the sheet that contains the referenced column; the error often appears in the “Inventory” tab for quantity fields.
