Overview

Error 18555 is a common pricing validation error that Amazon sellers encounter when listing or updating product prices in Seller Central. This error triggers when a selling price or sale price exceeds the maximum allowed price threshold set for your account. Understanding how to resolve this issue quickly is essential to keeping your listings active and avoiding lost sales.

Key Points / What Sellers Need to Know

• Price threshold violation — Error 18555 fires when the price you enter is higher than the maximum price Amazon expects for that product, which could indicate a data entry mistake.
• Common cause: typos — The most frequent trigger is accidental pricing errors such as extra zeros or misplaced decimal points (for example, entering $106 instead of $10.60).
• Sale prices included — This error applies to both your regular selling price and any sale price you set, so both fields need to fall within the acceptable range.
• Quick resolution available — You can fix this error by either correcting the price itself or adjusting your maximum allowed price threshold through several methods in Seller Central.

Why This Error Occurs

Amazon uses price threshold safeguards to protect sellers from accidentally listing products at dramatically incorrect prices. When you enter a selling price or sale price that exceeds your maximum allowed price threshold, Seller Central blocks the update and returns Error 18555. This is actually a protective measure — without it, a simple typo could result in a product being listed at ten times its intended price, potentially causing customer complaints, A-to-Z claims, or pricing policy violations. The error is most commonly triggered by data entry mistakes such as adding an extra zero, forgetting a decimal point, or pasting incorrect values from a spreadsheet.

How to Fix Error 18555

The first step in resolving this error is to double-check that the price you entered is actually correct and that all decimal points are properly placed. If you simply made a typo, correcting the price to fall within the acceptable threshold will immediately resolve the issue. However, if the price you entered is genuinely correct and you need to raise your threshold, Amazon provides three different methods to update your maximum allowed price. You can make changes directly through the Manage Inventory page, through individual listing edits, or by using a bulk upload template.
