Amazon Connect Service Quotas

The following table provides the default quotas for new Amazon Connect accounts as of February 2020. Because the quotas have been adjusted over time, the quotas in place for your account may be different than the quotas described here.

All service quotas can be adjusted/increased unless otherwise noted.

• To submit a service quota increase, use the Amazon Connect service quotas increase form. You must be signed in to your AWS account to access the form.

• 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.

Item	Default quota
AWS Lambda functions per instance	35
Agent status per instance	50 This quota cannot be increased.
Amazon Connect instances per account	2
Amazon Lex bots per instance	50
Concurrent calls per instance	10 If this quota is exceeded, contacts will get a reorder tone (also known as a fast busy tone), which indicates no transmission path to the called number is available. Tip You can calculate your configured quota using CloudWatch metrics. For instructions, see Use CloudWatch Metrics to Calculate Concurrent Call Quota. Or, edit a queue and enter an exceptionally large number for the contact limit. The resulting error message will display your quota.
Concurrent chats per instance	100 This includes chats that are waiting. If this quota is exceeded, the API call fails with a quota exceeded error.
Contact flows per instance	100
Hours of operation per instance	100
Phone numbers per instance	5
Prompts per instance	500
Queues per instance	50
Queues per routing profile per instance	50
Quick connects per instance	100
Rate of API requests	See Amazon Connect API Throttling Quotas.
Reports per instance	500 Personal saved reports count towards the reports per instance. For example, if one of your supervisors saves a report every day, it will count towards your overall number of saved reports per instance. As a best practice, we recommend you implement policies so reports don't pile up.
Routing profiles per instance	100
Scheduled reports per instance	50
Security profiles per instance	100
User hierarchy groups per instance	250
Users per instance	500

Amazon Connect is not available to customers in India using Amazon Web Services through Amazon Internet Services Pvt. Ltd (AISPL). You will receive an error message if you try to create an instance in Amazon Connect.

Amazon Connect API Throttling Quotas

Amazon Connect throttling quotas are by account, not by user and not by instance. For example:

• If different IAM 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 all other operations, a RateLimit of 2 requests per second, and a BurstLimit of 5 requests per second.

When you use the Amazon Connect Participant Service API, the number of requests per second is limited to the following:

• CreateParticipantConnection, DisconnectParticipant, and GetTranscript: a RateLimit of 2 requests per second, and a BurstLimit of 5 requests per second.

• SendEvent and SendMessage: a RateLimit of 10 requests per second, and a BurstLimit of 15 requests per second.
