I am referring to the article https://learn.microsoft.com/en-us/azure/azure-sql/database/adonet-v12-develop-direct-route-ports?view=azuresql regarding Azure SQL Database connection behavior.

The article states that dynamic ports 11000-11999 are required for ADO.NET connections, but it does not explicitly mention the port requirements for ODBC driver 17.

I would like to clarify whether dynamic ports are necessary when using the ODBC driver 17 to connect to an Azure SQL Database.

As per me – The ODBC driver uses the standard port 1433 for communication.
