Number types organize and identify number data that is stored in the entity database. Examples of default number types that are already configured in the entity database are phone and social security number.
If you have number data that is not defined by one of the default number types, you must create a new number type for that data.
<number> <num_type>ca</num_type> <num_value>41510155060</num_value> </number>In this instance, you need to set up a new number type called ca.
