Amazon Connect service quotas

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

• Create your instance (it must exist) and then 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.

• It can take up to a few days to increase your service quota. If you're increasing your quotas as part of a larger project, be sure to add this time to your plan.

• 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 quotas for new accounts created February, 2020 or later. Learn more
Active tasks per instance	2500
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 What is counted? All calls currently being handled by agents or waiting in a queue for an agent. Callbacks waiting in a callback queue are not counted until the callback is offered to an available agent. 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. For example, in the following image, it shows the quota for that instance is 99.
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 This quota refers to number of queue/channel combinations per routing profile. For example, in the following image there are two queues, but there are three queue-channel combinations: BasicQueue-Voice, BasicQueue-Chat, and Queue10-Voice. This counts three towards the service limit of 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	500 This quota applies to the total number of hierarchy groups you have, across all levels. There is no feature limit for how many hierarchy groups you can have for each level. For example, one level could have 500 hierarchy groups, which would reach the quota for your instance.
Users per instance	500

Note

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.

Countries you can call

You can place calls to the following countries when you create a new instance.

If you already have an instance, the countries that you are allowed to call may be different that those listed in the following table because we have changed the service quotas over time.
