++ Your nearest region is capacity constrained. West Europe is at capacity and unavailable for new instances. Other regions are [at capacity for specific tiers](search-sku-tier.md#region-availability-by-tier). One advantage to using the Azure portal for resource set up is that it provides only those regions and tiers that are available. You can't select regions or tiers that are unavailable.
 
-Review the [tier descriptions](search-sku-tier.md) for computing characteristics and feature availability.
++ You want to use integrated data chunking and vectorization or built-in skills for AI enrichment. Azure OpenAI and Azure AI services multiservice accounts must be in the same region as Azure AI Search for integration purposes. [Choose a region](search-region-support.md) that provides all necessary resources.
 
-Basic and Standard are the most common choices for production workloads, but many customers start with the Free service. Among the billable tiers, key differences are partition size and speed, and limits on the number of objects you can create.
++ You want to use Azure Storage for indexer-based indexing or you need to store application data that isn't in an index. Debug session state, enrichment caches, and knowledge stores are Azure AI Search features that have a dependency on Azure Storage. The region you choose for Azure Storage has implications for network security. Specifically, if you're setting up a firewall, you should place the resources in separate regions. For more information, see [Outbound connections from Azure AI Search to Azure Storage](search-indexer-securing-resources.md).

+Here's a checklist for choosing a region:
 
-Search services created after April 3, 2024 have larger partitions and higher vector quotas.
+1. Is Azure AI Search available in a nearby region? Check the [supported regions list](search-region-support.md). Capacity-constrained regions are indicated in the footnotes.
 
-Remember, a pricing tier can't be changed once the service is created. If you need a higher or lower tier, you should re-create the service.
+1. Do you know which tier you want to use? Check [region availability by tier](search-sku-tier.md#region-availability-by-tier) to determine if you can create a search service at the desired tier in your region of choice.
+
+1. Do you need [AI enrichment](cognitive-search-concept-intro.md) or [integrated data chunking and vectorization](vector-search-integrated-vectorization.md)? Verify that Azure OpenAI and Azure AI services are [offered in the same region](search-region-support.md) as Azure AI Search. 
+
+   Be aware that Azure AI Vision multimodal embeddings API, used for [integrated image vectorization](search-get-started-portal-image-search.md), must be accessed through an Azure AI multiservice account, but is available in a [smaller subset of regions](/azure/ai-services/computer-vision/overview-image-analysis#region-availability).
+
+1. Do you have business continuity and disaster recovery (BCDR) requirements? Such requirements dictate creating multiple search services in [regional pairs](../availability-zones/cross-region-replication-azure.md#azure-paired-regions) in [availability zones](search-reliability.md#availability-zones). For example, if you're operating in North America, you might choose East US and West US, or North Central US and South Central US, for each search service.
