Overview

Sellers uploading product or inventory feeds to Amazon sometimes encounter error 6000, which flags fields that should contain a positive whole number but instead hold letters, decimals, or other symbols. The error appears during flat‑file or XML feed submissions and can halt an entire batch, delaying listing updates. Understanding the root cause and the exact steps to correct it prevents costly re‑uploads and keeps catalog data flowing smoothly.

Key Points

• Positive integer requirement — The field in question must be a whole number greater than zero, such as 1, 27, or 842, with no letters, punctuation, or spaces.
• Typical offenders — Common culprits include decimal points (e.g., 4.5), commas used as thousand separators (e.g., 1,200), currency symbols (e.g., $15), fractions (e.g., 1/2), and stray whitespace introduced by copy‑pasting.
• Batch upload impact — Because the validation runs on the entire feed, a single malformed value can cause Amazon to reject the whole file, blocking dozens or hundreds of listings at once.
• Error location — Amazon’s error report usually cites the exact column name and row number, allowing sellers to pinpoint the problematic cell quickly.
• Quick fix — Replacing the offending entry with a clean integer—rounded up or down according to the field’s logic—resolves the issue in most cases.
• Prevention tip — Setting spreadsheet columns to “Number” with zero decimal places and running a pre‑submission validation check eliminates the majority of occurrences.

How Error 6000 Works

1. Feed ingestion — Amazon’s processing engine reads each row of the uploaded file and maps column values to internal data fields. Example: A seller submits a CSV where the “Quantity” column contains “12.0”.
2. Data type validation — For columns defined as positive integers, the system checks that the value consists solely of digits and is greater than zero. Example: The engine encounters “12.0”, detects the decimal point, and flags the row.
