# Projects maintained by CARTO in different BigQuery regions

CARTO keeps the latest version of the Analytics Toolbox for BigQuery in BigQuery projects in different locations.

When creating a connection to BigQuery, either the **service account** or the **user account** used for that connection **will be granted permission** to use the functions and procedures of the Analytics Toolbox in all the regions where it's available. Check the complete list of regions [**here**](/data-and-analysis/analytics-toolbox-for-bigquery/about-analytics-toolbox-regions.md).

You can [select the Analytics Toolbox location when creating a connection to BigQuery](/carto-user-manual/connections/bigquery.md#advanced-options-for-bigquery), allowing to use any of the regions where CARTO maintains the latest version of the Analytics Toolbox for BigQuery.

This setting will determine the SQL queries generated by Workflows components, Builder SQL Analyses, 'Create Tileset' and 'Enrich Data' functionalities.

By default, CARTO will automatically determine the corresponding AT Location based on the actual region of the data.
