AWS Service Limits

The following tables provide the default limits for AWS services for an AWS account. Unless otherwise noted, each limit is region-specific. Many services contain limits that cannot be changed. For more information about the limits for a specific service, see the documentation for that service.

AWS Trusted Advisor offers a Service Limits check (in the Performance category) that displays your usage and limits for some aspects of some services. For more information, see Service Limits Check Questions in the Trusted Advisor FAQs.

You can take the following steps to request an increase for limits. These increases are not granted immediately, so it may take a couple of days for your increase to become effective.

Amazon Connect Limits

The table provides the default limits for new Amazon Connect instances. Because the limits have been adjusted over time, the limits in place for your account may be different than the limits described here. There might be differences between the instances created for your account. For example, if you created an instance during the period when the default limit for concurrent active calls was set to 10, your instance is limited to 10 concurrent active calls. If you create a new instance today, the limit for the instance is 100 concurrent active calls.

To start, you can create five instances per AWS account in each of AWS Regions where Amazon Connect is available. If you need more instances, or an increase (or decrease) to any of the service limits, you can request an change using the Amazon Connect service limits increase form. You must be signed in to your AWS account to access the form.

There is also a service limit for the countries to which you can place outbound calls from your instance. If you already have an instance, the countries that you are allowed to call might be different that those listed in the following table because we have changed the service limits over time. You can submit a service limit increase request to allow calling to additional countries, or to limit the countries that you can call from your instance.
