Amazon Simple Notification Service endpoints and quotas
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.
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.
The following are the service endpoints and service quotas for this service.
Service endpoints
Service endpoints allow you to connect to other AWS services. The following endpoints support both standard and FIFO topics.

Service quotas
The following quotas determine how many Amazon SNS resources you can create in your AWS account, and they determine the rate at which you can issue Amazon SNS API requests.
Amazon SNS resource

| Delivery rate for transactional SMS messages | 20 messages per second |
| Delivery rate for email messages | 10 messages per second. This is a hard limit and can't be increased. |

The following quotas throttle the rate at which you can issue Amazon SNS API requests.

Soft
The following quotas vary by AWS Region. The messages per second quota is
based on the number of messages published to an Amazon SNS region, per account,
combining Publish and PublishBatch
API requests including both standard and FIFO topic types. To request a soft
limit increase, submit an SNS quota increase
request
For example, if your regional quota is 30,000 messages per second, per account, there are a few ways this quota can be reached:
-
Using the
Publishaction at a rate of 30,000 API requests per second to publish 30,000 messages (one message per API request). -
Using the
PublishBatchaction at a rate of 3,000 API requests per second to publish 30,000 messages (10 messages per batch API request). -
Using the
Publishaction at a rate of 10,000 API requests per second to publish 10,000 messages (one message per API request) and thePublishBatchaction at a rate of 2,000 API requests per second to publish 20,000 messages (10 messages per batch API request) for a total of 30,000 messages published per second.

*Amazon SNS FIFO per topic limits exceed the default per account limit when
FifoThroughputScope is set to MessageGroup. Amazon SNS
FIFO topics have a maximum per message group limit of 300 messages per second,
and Amazon SNS FIFO topics per topic throughput defaults to a limit of 3,000 messages
per second or 20MB per second, which ever comes first, when
FifoThroughputScope is set to Topic. Amazon SNS FIFO
topics can experience reduced throughput within a message group for cross
Regional deliveries due to the added latency between Regions, and the need to
maintain the strict order of messages.
