The term 'Address Part' refers to the components of an address. These components include a DOT (3 letters), STREET (6 letters), ZIP (3 letters), and ZIPCODE (7 letters). A DOT is typically used to separate the STREET number from the STREET name in an address. The STREET component of an address is the name of the STREET where the address is located. The ZIP component of an address is the three-digit code that identifies the area where the address is located. The ZIPCODE component of an address is the five-digit code that identifies the exact location of the address.
