Overview

Error 90225 is a feed processing error that Amazon sellers encounter when a product listing attribute exceeds the maximum allowed character or byte length. This is one of the more common listing errors, and it typically affects titles, bullet points, and other text-heavy fields. Understanding how to diagnose and resolve this error quickly can help sellers avoid delays in getting their products live on the marketplace.

Key Points / What Sellers Need to Know

• Character limits are enforced per attribute — Each product listing field, such as title, bullet points, and description, has a specific maximum character or byte length set by Amazon. Exceeding any one of these limits will trigger the error.
• The error message identifies the problem field — The error notification specifies which attribute exceeded the limit and what the maximum allowed length is, making it straightforward to pinpoint the issue.
• Titles and bullet points are the most common culprits — These fields have strict length requirements that sellers frequently bump up against, especially when trying to pack in keywords or detailed product information.
• Hidden formatting can inflate character counts — Extra spaces, special characters, and invisible formatting carried over from word processors or spreadsheets can silently push your text over the limit.

Understanding the Error

When you submit product data through a feed — whether via flat file upload, API, or inventory management tools — Amazon validates every attribute against its defined character or byte limits. If any single attribute exceeds its maximum, Amazon rejects that specific entry and returns error 90225 along with a message that reads: "Value for '[attribute name]' is longer than the allowed maximum ([limit] [unit])." This tells you exactly which field is too long and what the cap is. The error prevents the listing from being created or updated until the issue is corrected.

How to Resolve Error 90225

Fixing this error is a straightforward process. Start by reviewing your feed processing summary report, which will identify the exact attribute that triggered the error. Once you know which field is the problem, check the current length of your text against Amazon's stated maximum. Trim the content down to fit within the allowed limit, focusing on removing redundant words, unnecessary qualifiers, or excessive keyword stuffing. Pay special attention to hidden spaces or formatting artifacts that may have been introduced when copying text from external documents. After making your edits, re-submit the updated template or feed file.
