How to Fix Amazon Listing Error 90000596: Range Value Mismatch
Explains Amazon listing Error 90000596, which occurs when a product attribute's base value exceeds its 'to range' value, and how sellers can quickly fix and prevent it.
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.
Analysis & Recommendations
Why This Matters
Sellers who upload products via inventory files may encounter this validation error, which blocks listing creation until corrected. Understanding the fix saves time during bulk uploads.
Key Takeaways
- Error 90000596 means your range minimum value is greater than the range maximum — swap or correct them
- Always download the latest inventory file template to ensure correct field names and valid values
- Build pre-upload validation checks to catch range mismatches before submitting to Amazon
Recommended Actions
- →Review and correct any product attribute where the base value exceeds the 'to range' value, then resubmit
- →Download the latest inventory file template from Seller Central for your product type
- →Add a spreadsheet formula or script to validate range fields before bulk uploads
