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.
