Overview

Amazon’s error code 8105 appears when a value entered for a product attribute does not match the exact options Amazon’s catalog expects. The issue shows up during flat‑file or inventory‑template uploads and stops listings from going live. Sellers must correct the mismatched values to keep their catalog flowing smoothly.

Key Points

• Invalid attribute values — The error fires when a field contains text that Amazon’s system does not recognize, such as typing “Dark Blue” where the allowed list only includes “Blue” or “Navy.”
• Template “Valid Values” tab — Every Amazon inventory template ships with a hidden sheet that enumerates every permissible entry for each column; ignoring it is the fastest way to trigger 8105.
• Orange cell highlighting — After a failed upload, Amazon colors the offending cells orange in the downloaded error report, giving sellers a visual cue of which attributes need fixing.
• Linked (dependent) attributes — Some fields depend on the choice made in another column; for example, selecting “Men’s Shirt” may restrict the “Fit” column to “Regular” or “Slim” only. A mismatch between the two still counts as an invalid value.
• Product identifier formatting — GTINs, UPCs, and EANs must meet strict length and character rules; a 12‑digit UPC entered with a leading zero or a stray space will cause 8105 even though the number itself is correct.
• Copy‑paste pitfalls — Pasting data from spreadsheets, PDFs, or web pages can introduce invisible characters (non‑breaking spaces, line breaks) that make a perfectly valid entry appear invalid to Amazon’s parser.

How to Fix Error 8105

1. Open the inventory template and locate the “Valid Values” sheet — This hidden tab lists every acceptable entry for each attribute column; for a “Color” field it might show “Red, Blue, Green, Navy.”
2. Identify orange‑highlighted cells in the error report — Download the processing report, find the orange cells, and note the column name (e.g., “Material”).
3. — If the report shows “Cotton‑Blend” in the “Material” column but the valid list only contains “Cotton” and “Polyester,” replace the entry with one of the allowed options.
