# Managing product versions
<a name="ml-manage-product-version"></a>

 As a seller, you can manage your product versions in AWS Marketplace by updating existing version information, adding new versions, or removing versions that are no longer supported. Each version has a unique SageMaker AI ARN and associated information that buyers use to evaluate and deploy your product. 

**Note**  
 Before adding versions, create a product ID and establish pricing. For more information, see [Step 1: Create a new listing](create-new-listing.md). 

## Updating version information
