Overview

Error 90216 is a data validation error that Amazon returns when a product listing contains an attribute value that does not conform to the expected format, range, or set of accepted values. This is one of the more common feed and listing errors sellers encounter when creating or updating products through Seller Central, flat files, or the SP-API. Understanding what triggers this error and how to resolve it is essential for maintaining smooth catalog operations.

Key Points / What Sellers Need to Know

• Template error with variable details — The error message follows the pattern "Value for '{attribute_name}' is invalid" and includes a reason code explaining why Amazon rejected the value. The specific attribute name and reason will vary depending on the listing field that triggered the error.
• Affects any listing attribute — This error is not limited to a single field. It can appear for product dimensions, weight, color, material type, item type keywords, bullet points, or any other catalog attribute where Amazon enforces validation rules.
• Common in bulk uploads — Sellers using flat file uploads, inventory loader files, or API-based listing tools are most likely to encounter this error, since manual Seller Central listing forms often prevent invalid values at the input stage.
• Blocks listing creation or updates — When this error occurs, Amazon will reject the affected listing or update entirely. The product will not go live or reflect changes until the invalid value is corrected and the feed is resubmitted.

Common Causes

Error 90216 typically fires when a submitted value falls outside of Amazon's accepted parameters for a given attribute. This includes entering text in a numeric-only field, providing measurements that exceed Amazon's maximum thresholds, using values not found in Amazon's controlled dropdown list for that category, or submitting data in the wrong unit of measure. For example, entering a package weight of "50000" pounds when Amazon expects kilograms, or providing a color value of "Midnight Ocean" when the category only accepts standardized color names like "Blue" or "Black," would both trigger this error. Category-specific requirements are a frequent culprit, since each product type on Amazon has its own set of valid values for many attributes.
