# Enabling Region Locking

# Host regional competitions and allow specific countries for your registration.

Region Locking helps tournament organizers control the participant registration from specific countries they only wish to invite. Organizations and pro leagues handling international competitions can take advantage of this feature. This is also recommended for locally hosted tournaments that aims to reduce lag, delay, and high latency issues for online matches.

Click **Settings** from the bracket and scroll down to **Experimental Features**. Enable the **Allow specific countries for your registration?** option, type in a specific country and select from the search result.
