# AWS Organizations endpoints and quotas
<a name="ao"></a>

To connect programmatically to an AWS service, you use an endpoint. AWS services offer the following endpoint types in some or all of the AWS Regions that the service supports: IPv4 endpoints, dual-stack endpoints, and FIPS endpoints. Some services provide global endpoints. For more information, see [AWS service endpoints](rande.md).

Service quotas, also referred to as limits, are the maximum number of service resources or operations for your AWS account. For more information, see [AWS service quotas](aws_service_limits.md).

The following are the service endpoints and service quotas for this service.

## Service endpoints
<a name="ao_region"></a>

Because AWS Organizations is a global service, there is a single global endpoint for all of the AWS Regions in each partition.
