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 weeks 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 October, 2020 or later. Learn more
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
Amazon Lex V2 bot aliases per instance	100
Concurrent active calls per instance	10 What is counted? A contact is counted when it is in the following state: Handled by a contact flow Waiting in queue Handled by an agent Outbound call The following are not counted: Callbacks waiting in a callback queue are not counted until the callback is offered to an available agent. Exernal transfers 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. If you're only taking calls: Another way to determine your concurrent calls quota is to edit a queue and enter an exceptionally large number for the contact limit. The resulting error message will display your quota for concurrent calls. For example, in the following image, it shows the call quota for that instance is 99.
Concurrent active chats per instance	100 This includes chats that are waiting. If this quota is exceeded, the API call fails with a quota exceeded error. By default Maximum contacts in queue is set to your Concurrent calls per instance quota. If you plan to have more chats than that in a queue, submit a request to increase the Active chats per instance quota, and then increase the Maximum contacts in queue setting.
Concurrent active tasks per instance	2500 concurrent active tasks What is counted? All tasks that have not yet ended are considered active and are counted as concurrent tasks: tasks that are being routed in flows, waiting in a queue for an agent, being handled by agents, or being run in After Contact Work (ACW). By default Maximum contacts in queue is set to your Concurrent calls per instance quota. If you plan to have more tasks than that in a queue, submit a request to increase the Active tasks per instance quota, and then increase the Maximum contacts in queue setting.
Contact flows per instance	100
Hours of operation per instance	100
Maximum duration that a task can be scheduled in future	6 days
Modules per instance	200
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: Escalation queue Voice, Escalation queue Chat, and BasicQueue 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	2000 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 This quota cannot be increased.
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.

Derive Concurrent active sessions based on your Amazon Connect call volume

Use the information in the following table to derive your quota for Voice ID Concurrent active sessions per domain. Base your quota on the number of voice calls handled by your Amazon Connect contact center where Voice ID is enabled.

Amazon Connect Voice Contacts (Calls)/Hour*	Voice ID Concurrent active sessions
1,000	50
5,000	250
10,000	500
20,000	1,000
50,000	2,500

*For the calculations in the preceding table, we assume a fairly uniform distribution of calls during the hour. If you have more complex traffic patterns, contact AWS Support with details about your anticipated traffic pattern.

About default quotas

The preceding tables that lists service quotas 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.

Limit on creating and deleting instances	100 instances can be created or deleted in 30 days Amazon Connect enforces a limit on the total number of instances that you can create and delete in 30 days. If you exceed this limit, you will get an error message indicating there has been an excessive number of attempts at creating or deleting instances. You must wait 30 days before you can restart creating and deleting instances in your account. For example, if you create 80 instances and delete 20 over the course of 30 days, you must wait an additional 30 days before you can create or delete any more instances. If you create and delete the same instance 100 times in 30 days, the limit also applies.

Countries you can call

The Region where your instance is created determines which countries you can call by default.

Submit a service quota increase request to allow calling to additional countries, or to limit the countries that you can call from. You must be signed in to your AWS account to access the form.

For a list of all the countries available for outbound calling, see Amazon Connect pricing.

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