Overview

Amazon Seller Central's 20000 series error codes are among the most commonly encountered issues when uploading product feeds, managing inventory, or updating listings. These errors typically relate to data validation failures in product information submitted through flat files, inventory loaders, or API feeds. Understanding what each code means and how to resolve it can save sellers significant time and prevent listing delays.

Key Points / What Sellers Need to Know

• These are feed-processing errors — They appear when Amazon's systems reject data submitted through inventory files, flat file uploads, or feed submissions via Seller Central or the SP-API.
• Each code signals a specific data issue — The error number corresponds to a particular validation rule that your product data failed to meet, such as missing required fields, invalid values, or formatting problems.
• Errors block listing creation or updates — Until the underlying data issue is corrected and the feed is resubmitted, the affected listings will not be created or updated as intended.
• Batch processing means multiple errors at once — A single feed upload can trigger several different 20000 series errors across different SKUs, so sellers should review the full processing report rather than fixing issues one at a time.
• Most errors are straightforward to fix — The majority of these codes point to missing or malformed data fields that can be corrected in your flat file or inventory template before resubmission.

Common 20000 Series Error Codes Explained

Error 20000 is a general data error indicating that a value provided in your feed does not match Amazon's expected format or accepted values for that field. This is often a catch-all when the submitted data cannot be parsed correctly. Error 20002 typically signals that a required field is missing from your submission — common culprits include product type, brand name, or manufacturer. Error 20004 indicates that the value you submitted for a particular attribute is not among Amazon's accepted values for that field, which frequently occurs with item type keywords or browse node assignments.
