# Move an Amazon Connect phone number across instances
You can move a phone number from one Amazon Connect instance or traffic distribution group to another Amazon Connect instance or traffic distribution group in the same AWS account and Region, different AWS accounts, or different Regions.
Amazon Connect supports the following scenarios for migrating phone numbers:
+ Both Amazon Connect instances are in the same AWS Region and AWS account. In this scenario, you can move the numbers yourself.
+ The old and new Amazon Connect instances are in different Regions, but same account. AWS Support must migrate the numbers for you.
+ The old and new Amazon Connect instances are in same AWS Regions but different AWS accounts. AWS Support must migrate the numbers for you.

## Important things to know
The following information applies to phone number migrations that are performed by AWS Support.
+ If your new instance ARN belongs to traffic distribution group, you need to provide AWS Support with the instance and traffic distribution group ARNs. To obtain the traffic distribution group ARN, run a [list-traffic-distribution-groups](https://docs.aws.amazon.com/cli/latest/reference/connect/list-traffic-distribution-groups.html) CLI command.
+ AWS Support can schedule migrations anytime between Monday and Friday. Exceptions to this are local National Holidays when no phone number migrations can be scheduled.
+ When the migration date and time arrives, you must make sure the phone number is no longer configured as the outbound callback number on any of your queues. Otherwise, this will prevent AWS Support from migrating the number and it may delay the process.
+ The migration of each phone number takes between 20-30 minutes. During a phone number migration, **calls may be blocked and may fail for the number being migrated**.
+ To eliminate additional downtime, if you're associating a flow to a migrated phone number in the new Amazon Connect instance, make sure the flow exists and is published in the new Amazon Connect instance. Provide AWS Support with the flow ARN so they can associate it with the phone number when they do the migration.
+ Depending on the phone number, migration might not be possible. You'll be contacted through your AWS Support case if this applies to your request. Refer to the [Amazon Connect Telecoms Country Coverage Guide](https://d1v2gagwb6hfe1.cloudfront.net/Amazon_Connect_Telecoms_Coverage.pdf) for regional availability of phone numbers in certain countries.
+ After your phone number is migrated, you must set the outbound number on your queues. This cannot be done by AWS Support.
AWS Support will request that you acknowledge and understand the above information before they schedule your phone number migration.
## Self-move: same Region and AWS account
When both Amazon Connect instances are in the same Region and AWS account, you can move the phone number yourself by using the [ListPhoneNumbersV2](https://docs.aws.amazon.com/connect/latest/APIReference/API_ListPhoneNumbersV2.html) and [UpdatePhoneNumber](https://docs.aws.amazon.com/connect/latest/APIReference/API_UpdatePhoneNumber.html) APIs.
**Note**
If you receive errors when running AWS CLI commands, make sure that you're using the [most recent AWS CLI version](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-troubleshooting.html).
For instructions and sample CLI commands, see [How do I migrate phone numbers from one Amazon Connect instance to another?](https://repost.aws/knowledge-center/connect-migrate-phone-number)
## Different Regions and/or AWS account
When the old and new Amazon Connect instances are located in different Regions, but the same AWS account, complete the following steps to create a single AWS Support case.
When the old and new Amazon Connect instances belong to different AWS accounts, create two AWS Support cases, one from each account, following the same steps.
1. Sign in to your AWS account and then click [here](https://console.aws.amazon.com/support/home#/case/create?issueType=customer-service&serviceCode=service-connect-number-management) to access a pre-populated form in the AWS Support console.
