Can DNS Zones be created in Bulk

You can conveniently register up to five domains at once using the AWS Route53 UI console. However, for bulk registration tasks, it's advisable to utilize the Route53domain command line tool.

Please be aware that for AWS accounts created after March 2021, the default domain registration limit is set at 20. If your requirements exceed this number, it's important to request an increase in this limit prior to initiating bulk registration operations. For more details on these limitations and the request process, refer to the AWS documentation here.
