Parsing is the process of separating the address lines into separate address fields. It does not check whether or not the address fields constitute a valid postal address.

A call to

ssan3_addr_parse

returns a Long Array of field lengths. These correspond to the lengths of the parsed address fields, as per the table below. Fields with a length of zero simply mean that a particular address component was not present (for example, a middle name).

Field Index	Address Field
0	Organization
1	Department
2	Nobility (e.g. Lord)
3	Title (e.g. Mr)
4	First Name
5	Middle Name
6	Last Name
7	Function (e.g. Manager)
8	Building
9	Sub-Building
10	Street_1
11	Street_2
12	House Number
13	P.O. Box
14	Dependent Locality (e.g. URB, Colonia)
15	Locality (e.g. County)
16	Province (e.g. State)
17	Zip Code
18	Country
19	Double Dependent Locality
20	Sorting Code (Mail Sort)
21	County Information
22	Zip+4
23	Geocoding Latitude
24	Geocoding Longitude
25	Geocoding Unit
26	Residue

For example, field length [13] represents the length of the "PO Box" component of the address.
