Overview

Amazon Seller Central allows sellers to modify many aspects of their promotions after creation, but certain core elements are locked once a promotion is set up. Understanding which fields are editable and which are permanent is essential for avoiding costly mistakes when running promotional campaigns.

Key Points / What Sellers Need to Know

• Most promotion details are editable — After creating a promotion, you can go back and adjust many of its settings, including the promotion description, claim code text, and internal notes.
• Promotion type is permanent — Once you select a promotion type (such as percentage off, buy one get one, or free shipping), it cannot be changed after creation.
• Core conditions are locked — The fundamental structure of your deal, including the purchase requirements, what the buyer gets, applicable limits, and the specific benefit offered, cannot be altered once saved.
• Start dates become fixed — After a promotion's start date has passed, you can no longer modify that date. Plan your launch timing carefully before activating.
• Product selection lists cannot be changed — The type of product selection list associated with your promotion is set at creation and cannot be switched afterward.
• Claim code settings are final — Whether your promotion requires a claim code or is automatically applied is determined at creation and cannot be toggled later.

What You Can Edit

Sellers retain flexibility over several promotional elements after a promotion has been created. You can update the promotion's descriptive text, adjust the end date (provided the promotion hasn't already expired), and modify messaging that appears to customers. If you need to tweak how a promotion is presented to shoppers or extend its duration, these changes can typically be made through the promotion management dashboard in Seller Central. Navigate to the Advertising tab, select Promotions, find the promotion you want to modify, and click the edit option to make your adjustments.

What You Cannot Edit

Several critical fields become permanently locked once a promotion is created. The promotion type itself — whether it's a percentage off, a buy-one-get-one deal, or another format — is fixed from the moment of creation. The core deal conditions, including purchase requirements (what a buyer must do to qualify), what the buyer receives, applicable quantity or value limits, and the specific benefit amount, are all immutable. Additionally, once a promotion has started running, its start date cannot be retroactively changed. The product selection list type and the claim code requirement setting are also permanently set at creation. Amazon also maintains an audit log of promotion changes, and historical notes within that log cannot be modified or removed.
