Overview

Error 90111 is one of the most frequently encountered feed submission errors on Amazon Seller Central. It occurs when a value provided for a product attribute does not match Amazon's expected format or accepted values. Understanding how to diagnose and resolve this error can save sellers significant time when creating or updating product listings in bulk.

Key Points / What Sellers Need to Know

• Error trigger — This error fires when a value submitted for a specific attribute field does not conform to Amazon's required format, data type, or list of accepted values.
• Common culprits — Attributes like quantity (which must be numeric), price (which accepts decimals), and category-specific fields each have strict formatting rules that must be followed exactly.
• Template guidance available — Amazon provides detailed formatting requirements in the "Data Definitions" and "Valid Values" tabs of each product category's flat file template.
• Batch impact — A single invalid value in a feed file can cause the entire row to be rejected, meaning none of that product's data will be updated until the error is corrected.
• Error message format — The error typically reads: "{attribute name} field contains an invalid value: {value}. Value {input provided} is not a valid value."

How the Error Occurs

Error 90111 is generated during Amazon's feed processing when the system validates each field in a submitted inventory file against its expected data type and list of permissible values. For numeric fields such as quantity or package dimensions, Amazon expects whole numbers with no letters, special characters, or extra spaces. For price-related fields, decimal values are accepted but must follow a standard format such as "19.99" rather than using currency symbols or commas. Category-specific attributes often have a fixed list of valid values — for example, a "color" field may only accept values from Amazon's predefined color map, and entering a freeform color name that is not on that list will trigger this error.

How to Resolve the Error

The most reliable way to fix Error 90111 is to consult the flat file template for your specific product category. Download the most current version of your category's template from the "Add Products via Upload" section in Seller Central. Open the template and navigate to the "Data Definitions" sheet, which provides detailed formatting requirements for every attribute — including whether a field expects text, numbers, decimals, or values from a specific list. Next, check the "Valid Values" tab, which lists every accepted value for drop-down and enumerated fields. Compare the values in your feed file against these references, correct any mismatches, and resubmit the file. Pay particular attention to fields where you may have inadvertently introduced extra spaces, special characters, or formatting from spreadsheet auto-corrections.
