Overview

Amazon Seller Central throws error 13001 when a product’s inventory quantity is entered at or above 99,999,999 units. The validation runs for both manual entries and bulk file uploads, and it stops the listing from being saved. Sellers who handle large inventories or rely on spreadsheets need to recognize the trigger and apply a quick fix to keep their catalog up‑to‑date.

Key Points

• Hard ceiling of 99,999,999 units — Any quantity that meets or exceeds this figure is rejected with error 13001.
• Applies to all entry methods — The limit is enforced whether you type the number directly in Seller Central or submit a flat‑file inventory upload.
• Typical cause: data‑entry slip — Accidental extra digits, copy‑paste mishaps, or spreadsheet formulas that generate inflated numbers are the most common origins.
• Resolution is a simple reduction — Lower the quantity to any value below 99,999,999 and re‑submit the listing or file.
• Bulk uploads amplify the risk — When hundreds of rows are processed, a single oversized value can cause the entire file to be rejected.
• Proactive validation prevents recurrence — Adding spreadsheet rules or pre‑upload checks catches the problem before Amazon’s system does.

How to Resolve the Quantity Limit Exceeded Issue

1. Locate the offending quantity — Open the listing edit screen or the inventory file and find the cell that contains 99,999,999 or a higher number. For example, a manual entry of “100,000,000” in the Quantity field will trigger the error.
2. Adjust the number to a permissible value — Replace the oversized figure with a realistic count, such as changing “100,000,000” to “10,000”. The new value must be any integer below 99,999,999.
3. Resubmit the corrected data — Save the edited listing in Seller Central or re‑upload the revised flat file. After the correction, Amazon should accept the submission without further error messages.
