The following sections include the supported AWS Regions and service quotas for Amazon S3 Vectors.

## S3 Vectors AWS Regions and endpoints
<a name="s3-vectors-regions-endpoints"></a>

Amazon S3 Vectors is currently available in the following AWS Regions. To connect programmatically to an AWS service, you use an endpoint. For more information about AWS service endpoints, see [AWS service endpoints](https://docs.aws.amazon.com/general/latest/gr/rande.html) in the AWS General Reference. For more Amazon S3 endpoint information, see [Amazon S3 endpoints and quotas](https://docs.aws.amazon.com/general/latest/gr/s3.html) in the AWS General Reference.

S3 Vectors endpoints are dual-stack endpoints that support requests over IPv6 and IPv4.

S3 Vectors supports private connectivity with AWS PrivateLink interface endpoints. For more information, see [VPC endpoints for S3 Vectors](s3-vectors-privatelink.md).

## S3 Vectors service quotas
<a name="s3-vectors-service-quotas"></a>

Quotas, also referred to as limits, are the maximum number of service resources or operations for your AWS account. The limits are the service quotas for S3 Vectors resources.

For detailed limits that apply to S3 Vectors, see [Limitations and restrictions](s3-vectors-limitations.md).

Unless otherwise noted, each quota is per AWS Region. You can request increases for some quotas, and other quotas can't be increased. For more information about requesting a quota increase, see [Requesting a quota increase](https://docs.aws.amazon.com/servicequotas/latest/userguide/request-quota-increase.html) in the *Service Quotas User Guide*. For more Amazon S3 quota information, see [Amazon S3 endpoints and quotas](https://docs.aws.amazon.com/general/latest/gr/s3.html) in the *AWS General Reference*.
