How do I choose which region to deploy my Serverless Functions in?

The Vercel platform caches all static content at the edge by default. This means that without any changes, your static files are immediately available from all Vercel regions.

Serverless Functions are deployed to the IAD1 region by default to ensure your Serverless Functions are located close to most external data sources hosted on the East Coast of the USA. Depending on your account plan, the deployment region can be changed.

Note:

Projects created before January 14, 2021, default to San Francisco, USA (SFO1). We recommend updating these projects to the new default of Washington, D.C., USA (IAD1).

Hobby

For Hobby accounts, the default deployment region for Serverless Functions of IAD1 cannot be changed. As a result, it is recommended to locate your data source as close to this region as possible.

Pro Teams

For Pro team accounts, the default deployment region for Serverless Functions is IAD1.

These accounts are able to change this by selecting a single region for Serverless Functions to be deployed in.

Warning:

For the best performance, deploy your Serverless Functions in the region closest to your data source.

Enterprise Plans

For Enterprise accounts, the default deployment region for Serverless Functions is IAD1.

These accounts are able to change this by selecting multiple regions for Serverless Functions to be deployed in.

If you believe your project requires an Enterprise plan, please contact our Enterprise department.
