As per my knowledge, we have 4 options to store an Address in Salesforce 

1: Use the Standard Address Compound Data Type 

2: Add Extra Fields on an sObject or Create a Custom M:M Relation sObject 

3: Use the Custom Address Compund Meta Data Type 

4: Use the Location and Address sObjects 

We have a requirement for adding multiple fields to the Address Entity 

- County 

- County Code 

- Municipal 

- Municipal Code 

- Cadastral Unit 

- Property Unit 

- Utility Unit 

I know we can do this using either of the above, however, I would like to get some experiences, especially from Scandinavian Customers, how these were implemented with Pros & Cons. 

Right Now I'm looking into Location and Address to enable most of the Properties we need for further Design Enhancements in Flows, Integrations, LWCs and similar. 

Another Key is that we need multiple Address Types for each Business Relation ( Account ) 

Examples are: 

- Delivery Address 

- Pickup Address 

- Invoice Address 

- Return Address 

- Warehouse Address 

- Postal Address 

- Visiting Address 

And Similar. Within these we may also have multiple subsidiaries and parents since an Organization may be International and have a Complex Hierarchy. 

Thank you in advance.
