Overview

Error 90242 is a product listing validation error that Amazon sellers may encounter when creating or updating listings in Seller Central. This error fires when a value entered for a specific product attribute exceeds the maximum allowed limit set by Amazon's catalog system. Understanding how to diagnose and resolve this error can help sellers avoid listing delays and keep their catalog running smoothly.

Key Points / What Sellers Need to Know

• What triggers it — Error 90242 appears when a value you submit for a product attribute is higher than the maximum threshold Amazon permits for that field. The error message will specify the exact attribute name, the value you entered, and the limit it must fall below.
• Where it occurs — This error can surface when uploading flat files, using inventory feeds, making changes through the Add a Product tool, or submitting data via the SP-API. Any method of catalog data submission is subject to these validation checks.
• Common culprits — Numeric fields like weight, dimensions, price, and quantity are frequent offenders. For instance, entering a package weight of 500 pounds when the category maximum is 150 pounds would trigger this error.
• It blocks your listing — Until the offending value is corrected, Amazon will not accept the listing submission or update. The error must be resolved before your product can go live or reflect changes.

How This Error Works

Amazon's catalog system enforces validation rules on every product attribute to maintain data quality across the marketplace. Each attribute in a given product category has defined acceptable ranges. When you submit listing data, Amazon checks each field against these limits before accepting the submission. If any value falls outside the acceptable range — specifically, if it is not less than the stated maximum — the system rejects that field and returns Error 90242 with a message formatted as: "Value '{value}' for '{attribute_name}' is not less than the limit '{limit}'." This tells you exactly which attribute failed validation, what you submitted, and what the upper boundary is.

How to Fix Error 90242

Start by reading the error message carefully. It contains three critical pieces of information: the value you submitted, the attribute name that failed, and the maximum limit for that attribute. Your fix is straightforward — revise the value so it falls below the stated limit. If you are uploading via flat file or feed, locate the corresponding column and correct the entry. If using the Add a Product interface, find the relevant field and adjust it. Double-check that you are using the correct unit of measurement, as a mismatch between units (such as entering centimeters in a field expecting inches) is a common cause of values appearing too large. Also verify that you have not accidentally included extra digits or decimal point errors in your data.
