The type affinity of a column is the recommended type for data stored in that column. The CHECK constraints are very useful to place additional logic to restrict values that the columns can accept at the database layer. The important idea here is that the type is recommended, not required. It also specifies an ID column that uses the PRIMARY KEY constraint. Phone number should be converted into E.164 before storage.
