# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.carto.com/data-and-analysis/analytics-toolbox-for-bigquery/getting-access/projects-maintained-by-carto-in-different-bigquery-regions.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
