Overview

Sellers may see error code 90000644 when Amazon rejects a product feed because the list price contains more decimal places than the marketplace permits. The issue appears during initial listing, bulk uploads, or price updates, and it can stall product visibility. Fixing the decimal‑place mismatch quickly restores the feed and keeps listings on schedule.

Key Points

• Root cause — The validation engine flags any list‑price entry that exceeds the allowed number of decimal places; some categories accept only whole numbers.
• Affected attribute — The field known as list_price, recommended retail price or RRP triggers the error when its format is non‑compliant.
• Typical decimal limit — While most marketplaces allow two‑digit precision (e.g., 12.99), certain regions or categories enforce zero‑decimal pricing (e.g., 13).
• Simple remedy — Rounding or truncating the price to the permitted precision and resubmitting the feed clears the error.
• Cross‑marketplace nuance — Sellers operating in multiple locales must track each marketplace’s specific decimal‑place rule to avoid repeated rejections.

How Error 90000644 Is Triggered

1. Data submission — A seller uploads product information via the Add a Product form, a flat‑file template, or an API inventory feed. Example: a CSV file lists a new kitchen gadget with a list price of 19.95.
2. Field parsing — Amazon’s ingestion engine reads each column and maps the list_price value to the internal pricing schema. Example: the system extracts “19.95” from the CSV’s ListPrice column.
3. Decimal‑place validation — The platform checks the extracted price against the marketplace‑specific rule set. If the rule for the target locale specifies zero decimal places, any value containing a period is deemed invalid. Example: the UK marketplace requires whole‑number pricing, so “19.95” fails the check.
