# Nested OU
<a name="cfct-nested-ou"></a>

CfCT supports listing one or more nested OUs under the `organizational_units` keyword in manifest V2 version (2021-03-15). 

A complete path (excluding Root) for the nested OU is required, using a colon as the separator between OUs. For deployment method `scp` or `rcp`, AWS Control Tower deploys the SCPs or RCPs to the last OU in the nested OU path. For deployment method `stack_set`, AWS Control Tower deploys the stack sets to all the accounts under the last OU in the nested OU path.

For example, consider the path `OUName1:OUName2:OUName3`. The last OU in the path is `OUName3`. CfCT deploys the SCPs or RCPs to `OUName3` and stack sets to all of the accounts directly under `OUName3`, only.
