Overview

Amazon’s validation engine flags “Error 6000: Invalid Integer Characters” whenever a numeric field in a bulk upload contains characters that are not plain whole numbers. The issue appears during flat‑file or inventory‑feed submissions and can halt the processing of new or updated listings. Sellers must understand the root cause and apply a systematic fix to keep bulk uploads running smoothly.

Key Points

• Whole‑number requirement — Fields that trigger Error 6000 accept only non‑negative integers such as 0, 1, 25, or 500; negative values, decimals, or text are rejected.
• Typical offenders — Currency symbols ($), commas, letters (e.g., “A”), or punctuation inserted into numeric columns will cause the error.
• Decimals are invalid — Entering “7.0” instead of “7” leads to a failure, even though the value is mathematically equivalent.
• Fractions are not parsed — Entries like “1/2” or “3/4” cannot be interpreted as integers and will be blocked.
• Error report pinpoints characters — Amazon’s feedback lists the exact characters that broke validation, allowing sellers to locate the problem quickly.

How to Resolve Error 6000

1. Read the error details — Open the error report; it will name the column and show the offending characters (e.g., “Quantity contains ‘5,0’”).
2. Locate the problematic cell — In your spreadsheet, navigate to the indicated row and column; you might see “5,0” or “$12”.
3. Strip non‑numeric symbols — Delete any dollar signs, commas, spaces, or letters, leaving only digits (e.g., change “$12,000” to “12000”).
4. Convert decimals to integers — If the cell reads “8.5”, decide the correct whole number (usually rounding down or up per inventory policy) and replace it with “8” or “9”.
5. Replace fractions with whole numbers — For “1/2”, determine the appropriate integer quantity (often “0” or “1”) and enter that value.
6. Set column formatting — In Excel or Google Sheets, format the column as “Number” with zero decimal places; this prevents the program from auto‑adding commas or periods.
