How to Fix Error 95001: Missing or Invalid Column Values in Product Listings
Error 95001 is triggered when both identifiers in a required pair (e.g., UPC and ASIN) are missing or malformed; in a 1,000‑row bulk upload, 150 rows were rejected because the UPC field was blank and the ASIN contained invalid values. Supplying a valid 12‑digit UPC or a correct 10‑character ASIN and re‑uploading clears the error.
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
- 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.
- 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.
Analysis & Recommendations
Why This Matters
Rows flagged with 95001 never enter Amazon's catalog, causing delays in product launches and extra labor to fix data. In large feeds, dozens to hundreds of items can be rejected, increasing operational costs and risking missed sales opportunities.
Key Takeaways
- Both columns in a required identifier pair must have a valid value; if UPC and ASIN are both invalid, error 95001 is generated.
- Malformed values (e.g., a 5‑digit UPC or non‑numeric EAN) are treated as blank by Amazon's validation engine.
- In the example, 150 of 1,000 rows were rejected until a correct 12‑digit UPC or 10‑character ASIN was provided.
Recommended Actions
- →In Seller Central, download the processing report (Inventory > Add Products via Upload > Processing Report) to see the exact columns flagged.
- →Open the original feed in Excel, apply formulas like =LEN(UPC)=12 and =LEN(ASIN)=10 to identify invalid entries, then replace them with correct 12‑...
- →Re‑upload the corrected file via Seller Central (Inventory > Add Products via Upload) and verify the new processing report shows no 95001 errors.
