Overview

Error 90205 is a feed processing error that Amazon sellers encounter when an attribute value in their product listing exceeds the maximum allowed character or byte length. This is one of the more common listing errors, particularly affecting product titles and bullet points, and resolving it requires trimming your content to fit within Amazon's specified limits.

Key Points / What Sellers Need to Know

• Error trigger — This error fires when a submitted attribute value surpasses Amazon's maximum length constraint for that specific field, whether measured in characters or bytes.
• Common culprits — Product titles and bullet points are the most frequent attributes that trigger error 90205, though it can apply to any length-restricted field.
• Feed processing impact — The error appears in your feed processing summary report, which identifies exactly which attribute and listing caused the problem.
• Resolution is straightforward — The fix involves identifying the offending attribute, shortening its content, and resubmitting your listing feed.

How This Error Occurs

When you submit product data through a feed or listing template, Amazon validates every attribute against a set of constraints before publishing. One of those constraints is maximum length. If your product title, bullet points, or other text-based attributes exceed the allowed character or byte count, Amazon rejects the submission and returns error 90205 with a message identifying the specific attribute and value that failed validation. The error message follows the format: "${attribute_name} does not meet maximum length constraint for attribute ${value}." This tells you precisely which field needs attention, making diagnosis relatively simple compared to other listing errors.

How to Resolve Error 90205

Fixing this error involves a clear, step-by-step process. First, open your feed processing summary report to identify exactly which attribute triggered the error. Next, review the current character or byte length of that attribute and compare it against Amazon's published limits. For product titles, Amazon enforces specific requirements and guidelines that vary by category, so check the rules for your particular product type. Bullet points similarly have maximum length requirements that must be respected. Once you understand the limit, edit your content to fit within the constraint while preserving the most important information. Finally, resubmit your updated template or feed and verify that the error no longer appears in your processing report.
