# How do I resolve alias related errors on Vercel? **Author:** Sam Ko --- When adding a domain to a project, you may encounter one of two errors related to to the `alias` property: - "The chosen alias `.vercel.app` is already in use." - "To move the domain, remove existing aliases associated with ``." In both cases, you will need to remove the alias(es) in question in order to continue. This article covers the steps you can take to resolve these alias related errors. ## Steps to Resolve The alias may be in use within a Vercel Project's deployments. Check with any Vercel projects' deployments that may include this alias. If you find the alias, you will need to delete the deployment. If you did not find the alias in any of your deployments, check to see if this alias is currently in use by using this [Vercel CLI](https://vercel.com/docs/cli#getting-started) command: `vercel alias list` Make sure to check within all your Vercel accounts, both Hobby and teams, for this alias. You can switch the account [scope](https://vercel.com/docs/cli#commands/switch) by using this command: `vercel switch` If you were able to find the alias through this step, you can remove it with the following command: `vercel alias remove ` ## Deleted Accounts If you have recently deleted a Vercel Hobby or Pro team account, then please be aware that the domain is instantly available for use again. --- [View full KB sitemap](/kb/sitemap.md)
