Amazon Connect service quotas
All service quotas can be adjusted/increased unless otherwise noted.
Your AWS account has default quotas, formerly referred to as limits, for each AWS service.
To request a quota increase, see Requesting a quota
increase in the Service Quotas User Guide. If the quota is not yet
available in Service Quotas, use the Amazon Connect service quotas increase form
Contents
Important things to know
-
You must create your instance before you can request a service quota increase.
-
We review each request for a quota increase. For smaller increase requests, we can approve in hours. Larger increase requests take time to review, process, approve, and deploy. Depending on your specific implementation, your resource, and the size of quota that you want, a request can take up to 3 weeks. An extra-large worldwide increase can potentially take months. If you're increasing your quotas as part of a larger project, keep this information in mind and plan accordingly.
-
Use the same form to submit a request to port your US phone number from your current carrier to Amazon Connect. For more information about porting phone numbers, see Port your current phone number to Amazon Connect.
-
The quotas apply per AWS Region. You can have multiple Amazon Connect instances in each Region. It's possible to raise quotas for all instances in a Region.
-
Default quota values in this documentation are specifically for new accounts. Because quotas defaults have been adjusted over time, the default and applied quota values for your account might be lower than the default values described below.
-
Not all quotas can be adjusted.
-
There are two types of quota adjustability: account level and resource-level.
-
Account level quotas, when adjusted, will apply to all Amazon Connect instances in this account and region. For example, the maximum transactions per second (TPS) limits for a specific API.
-
Resource level quotas, when adjusted, will only apply to resources within a specific Amazon Connect instance. For example, the maximum number of users per instance. Resource level quotas cannot be adjusted at the account level.
-
Important
You need AWS CLI version 2.13.20 or higher to view and manage resource-level quotas such as Phone numbers per instance for Amazon Connect.

Derive Concurrent post-call analytics jobs based on your Amazon Connect call volume
A post-call analytics job is kicked off after the completion of each contact with Contact Lens enabled. The time to complete a post-call analytics job can vary, but for planning purposes, you can estimate that it usually takes about 40% of the call length. If you choose 40% for your estimate, to calculate concurrent post-call analytics jobs, you would use the following formula:
(average call duration in minutes) * (0.4) * (calls per hour) /
(60)
The following table shows some examples of what the approximate number of concurrent post call jobs would be if you assume the time to complete the analysis is 40%.

How contacts are counted
The following contacts are counted in Concurrent active calls per instance:
-
Handled by a flow
-
Waiting in queue
-
Handled by an agent
-
Outbound call
The following contacts are not counted:
-
Callbacks waiting in a callback queue are not counted until the callback is offered to an available agent.
-
External transfers
If the quota for Concurrent active calls per instance is exceeded, contacts get a reorder tone (also known as a fast busy tone), which indicates that there is no available transmission path to the called number.
You can calculate your configured quota using CloudWatch metrics. For instructions, see Use CloudWatch metrics to calculate concurrent call quota.
If you're only taking calls you can also determine your Concurrent active calls per instance quota by doing the following:
-
Navigate to the Edit a queue page: choose Routing, Queues, and choose a queue.
-
Choose Set a limit across all channels.
-
Enter an exceptionally large number in the Maximum contacts in queue box for the contact limit.
The resulting error message displays your quota as less than the sum of the following quotas combined: Concurrent calls per instance + Concurrent active chats per instance + Concurrent active tasks per instance.
For example, in the following image from the Edit queues page, you add 1 to the error message, to get Concurrent calls per instance + Concurrent active chats per instance + Concurrent active tasks per instance quota = 3010.
The error message shows 3009 because you must set always set Maximum contacts in queue to a number that is at least 1 less than your combined quota (which is the default limit).
API throttling quotas
Amazon Connect API throttling quotas
Amazon Connect throttling quotas are by account, and per Region, not by user and not by instance. For example:
-
If different users from the same account make requests, they are sharing a throttle bucket.
-
If multiple requests are sent from different instances from the same account, they are also sharing a throttle bucket.
When you use the Amazon Connect Service API , the number of requests per second is limited to the following:
-
For the GetMetricData and GetCurrentMetricData operations, a RateLimit of 5 requests per second, and a BurstLimit of 8 requests per second. For GetMetricData, you cannot increase throttle limits.
The default limits for GetMetricDataV2 are 10 requests per second.
-
For StartChatContact, StartContactStreaming, StopContactStreaming, CreateParticipant a RateLimit of 5 requests per second, and a BurstLimit of 8 requests per second.
-
For all Evaluations actions, the throttling quota is 1 request per second.
-
For all other operations, a RateLimit of 2 requests per second, and a BurstLimit of 5 requests per second.
Amazon Connect Participant Service API throttling quotas
For the Amazon Connect Participant Service, the quotas are by instance.
When you use the Amazon Connect Participant Service API, the number of requests per second is limited to the following:
-
CompleteAttachmentUpload: a RateLimit of 2 requests per second, and a BurstLimit of 5 requests per second.
-
CreateParticipantConnection: a RateLimit of 6 requests per second, and a BurstLimit of 9 requests per second.
-
DisconnectParticipant: a RateLimit of 3 requests per second, and a BurstLimit of 5 requests per second.
-
GetAttachment: a RateLimit of 8 requests per second, and a BurstLimit of 12 requests per second.
-
GetTranscript: a RateLimit of 8 requests per second, and a BurstLimit of 12 requests per second.
-
SendEvent and SendMessage: a RateLimit of 10 requests per second, and a BurstLimit of 15 requests per second.
-
StartAttachmentUpload: a RateLimit of 2 requests per second, and a BurstLimit of 5 requests per second.
Amazon Connect Contact Lens Service API throttling quotas
Amazon Connect Contact Lens throttling quotas are by account, not by user and not by instance. For example:
-
If different users from the same account make requests, they are sharing a throttle bucket.
-
If multiple requests are sent from different instances from the same account, they are also sharing a throttle bucket.
When you use the Amazon Connect Contact Lens API, the number of requests per second is limited to the following:
-
ListRealtimeContactAnalysisSegments: a RateLimit of 1 request per second, and a BurstLimit of 2 requests per second.
