Overview

Error 90231 is a product listing validation error that Amazon returns when a value submitted for a specific product attribute does not meet the minimum precision requirements. This error typically affects sellers who provide measurements, dimensions, weights, or other numerical attributes with insufficient decimal places. Understanding this error and how to resolve it is essential for sellers who manage catalog listings at scale or through feeds and automation.

Key Points / What Sellers Need to Know

• Precision refers to decimal places — When Amazon references "precision" in this context, it means the number of decimal places included in a numerical value. A precision of 2, for example, means at least two digits after the decimal point are required.
• The error is attribute-specific — Different product attributes may have different minimum precision thresholds. What works for one field may not be acceptable for another.
• Template values indicate dynamic fields — The error message contains placeholders like attribute name, submitted value, actual precision, and required threshold, which change depending on the specific listing and attribute involved.
• Common in feed-based submissions — Sellers using inventory file uploads, SP-API feeds, or third-party listing tools are more likely to encounter this error than those editing listings manually through Seller Central.
• Easily fixable — Once identified, the solution is straightforward: update the attribute value to include enough decimal places to satisfy the minimum precision requirement.

How This Error Occurs

Error 90231 is triggered during the listing validation process when Amazon's catalog system checks submitted attribute values against predefined rules. Each numerical attribute in Amazon's catalog schema can have a minimum precision requirement. For instance, if a product weight attribute requires at least three decimal places and a seller submits a value of "1.5" (which has a precision of one), the system will reject the submission with this error. The error message explicitly states both the actual precision of the submitted value and the minimum threshold required, giving sellers the exact information they need to correct the issue. This validation exists to ensure consistency and accuracy across product data in the Amazon catalog.
