Overview

Error 90000596 is a product listing validation error that Amazon returns when a value in a range field is entered incorrectly. Specifically, it triggers when the starting value in a measurement or size field is greater than the corresponding "to range" value. This is a common data entry issue that sellers encounter when creating or updating product listings through inventory files or Seller Central.

Key Points / What Sellers Need to Know

• What triggers the error — Error 90000596 fires when the value entered in a product attribute field (such as size) is greater than the corresponding "to range" value for that same attribute. Amazon expects the range minimum to be less than the range maximum.
• Where it appears — This error typically surfaces when submitting product information through inventory file uploads or when editing listing details directly in Seller Central.
• Root cause — The error is a straightforward data validation check. Amazon's system compares two related fields — a base value and a "to range" value — and rejects submissions where the base value exceeds the upper bound.
• Resolution is simple — Correcting the values so the "to range" field contains a number greater than the base field will resolve the error immediately upon resubmission.

How the Error Works

When you submit product information to Amazon's catalog, certain attributes require range values. For example, a product's size might need both a base measurement and an upper range limit. Amazon's validation system checks that these values are logically consistent — the starting point of a range must always be less than the endpoint. If you enter a base size of "2" for a product, the corresponding "to range" size field must contain a value greater than 2, such as "3" or "2.5." When this logical check fails, Amazon returns Error 90000596 and rejects the submission.

This validation applies across multiple product types and can affect various measurement fields depending on the category you are listing in. The specific fields involved will vary by product type definition.

How to Resolve the Error

To fix Error 90000596, review the values you entered in the affected fields and ensure the "to range" value is greater than the base value. Start by identifying which product attribute triggered the error — Amazon's error response will typically reference the specific field. Then update your listing data so the range values are in the correct ascending order and resubmit your product information.
