Overview

Amazon sellers may encounter validation error 95001 when they upload bulk product listings through Seller Central. The error appears when two required identifier columns in a feed row are either empty or contain values that do not meet Amazon’s formatting rules, blocking the item from being processed. Resolving the issue quickly is essential for sellers who rely on large‑scale uploads to keep inventory current and launch new products.

Key Points

• Dual‑column validation failure — The error is triggered only when both columns in a required pair fail validation, meaning Amazon needs at least one correct identifier to accept the row.
• Typical missing identifiers — Most often the problem stems from a blank or malformed UPC/EAN (primary identifier) combined with a missing or invalid ASIN (secondary identifier).
• Invalid data counts as blank — Values that violate length, character, or checksum rules are treated by Amazon as if the field were empty, so the system discards them during processing.
• Item‑level impact — The error is evaluated per row; some products in the same file may upload successfully while others are rejected with 95001.
• Error message specifies columns — Amazon’s processing report lists the exact column names that caused the failure, allowing sellers to pinpoint the problem rows.
• Re‑upload required after correction — Once the identifiers are fixed, the feed must be resubmitted and the new processing report reviewed to confirm the issue is cleared.

How Error 95001 Occurs

1. Feed submission and row validation — When a seller uploads a flat‑file or XML feed, Amazon scans each row against a set of mandatory field rules. For identifier pairs such as “UPC” / “ASIN” or “EAN” / “GTIN”, the system checks that at least one column holds a valid value.
2. Both columns fail — If the UPC column contains “12345” (only five digits) and the ASIN column is empty, Amazon flags the row because neither entry satisfies the required format.
