How to Fix Error 6000: Invalid Field Values in Amazon Product Listings
Explains Amazon listing Error 6000, which occurs when product data fields contain values not matching Amazon's accepted options. Covers common causes like typos and abbreviation mismatches, plus step-by-step resolution.
Overview
Error 6000 is a common listing feed error that Amazon sellers encounter when submitting product data with field values that don't match Amazon's predefined accepted options. Understanding this error and how to resolve it quickly can save sellers significant time during product listing creation and bulk uploads.
Key Points / What Sellers Need to Know
- Exact value matching is required - Amazon's listing system requires that certain fields contain values that precisely match a predefined list, with no variations or creative alternatives allowed.
- Common culprits include unit-of-measure fields - Fields like weight units, dimension units, and other standardized measurements are especially strict about accepted values.
- Typos are a frequent cause - Even small mistakes such as extra spaces, wrong capitalization, or minor misspellings will trigger this error.
- Abbreviation formatting matters - Adding a period to an abbreviation (e.g., "oz." instead of "oz") or spelling out an abbreviation (e.g., "ounces" instead of "oz") can cause a rejection if it doesn't match the expected format.
How This Error Works
When you submit product data to Amazon through flat files, inventory loaders, or API feeds, each field in the listing template has a set of data definitions that specify which values are acceptable. Error 6000 fires when the system detects that a value you entered for a particular field does not appear anywhere on its list of accepted inputs. This is a strict validation check — Amazon does not attempt to interpret what you meant or find the closest match. The field name referenced in the error message tells you exactly which attribute triggered the rejection, so you can pinpoint the problem quickly.
Common Causes and Examples
The most frequent reason sellers see this error is simple typographical mistakes. For instance, entering "Ibs" instead of "lbs" for a weight unit, or "inchs" instead of "inches" for a dimension field, will immediately cause a rejection. Another common scenario involves abbreviation formatting — some fields expect "oz" while a seller might enter "oz." with a trailing period, or vice versa. Similarly, some sellers spell out a term like "pounds" when the system only accepts the abbreviation "lb." The reverse also happens, where a seller uses a shorthand that the template doesn't recognize. Currency codes, color names, material types, and size designations are all fields where this error commonly appears.
Analysis & Recommendations
Why This Matters
Sellers doing bulk uploads or flat file submissions frequently encounter this validation error. Knowing how to quickly diagnose and fix it prevents listing delays and keeps product launches on schedule.
Key Takeaways
- Error 6000 means a field value doesn't match Amazon's predefined accepted options exactly
- Typos, extra periods on abbreviations, and spelling out shorthand are the most common causes
- Always reference your category's data definitions for the exact accepted values before submitting
- Accepted values can vary between product categories, so don't assume one format works everywhere
Recommended Actions
- →Download and keep your product category's flat file template handy as a reference for accepted field values
- →Spot-check unit-of-measure and restricted-value fields before every bulk upload submission
- →When you encounter this error, read the field name in the message and cross-reference it against the data definitions to find the exact accepted format
