Match Codes

Match Codes indicate the portions of the address that matched or did not match to the reference file. If a match could not be made, the Match Code begins with "E" and the remaining digits indicate why the address did not match (see Match Codes for No Match - Definitions for "Ennn" return codes). The digits do not specifically refer to which address elements did not match, but rather why the address did not match. These fields are always included in the output from AssignGeoTAXInfo.

Match Code Definitions

columnName	Description
`Ahh`	Same as `Shh`, but indicates match to an alias name record or an alternate record.
`Chh`	Street address did not match, but located a street segment based on the input ZIP Code or city.
`D00`	Matched to a small town with P.O. Box or General Delivery only.
`Ghh`	Matched to an auxiliary file.
`Hhh`	House number was changed.
`Qhh`	Matched to USPS range records with unique ZIP Codes. CASS rules prohibit altering an input ZIP if it matches a unique ZIP Code value.
`Rhh`	Matched to a ranged address.
`Shh`	Matched to USPS data. This is considered the best address match, because it matched directly against the USPS list of addresses. `S` is returned for a small number of addresses when the matched address has a blank ZIP + 4.
`Thh`	Matched to a street segment record. Street segment records do not contain ZIP Code information. If you enter a ZIP Code, the application returns the ZIP Code you entered. If the input city and state has only one ZIP Code, the application returns that ZIP Code.
`Uhh`	Matched to USPS data but cannot resolve the ZIP + 4 code without the firm name or other information.
`Xhhh`	Matched to an intersection of two streets, for example, “Clay St & Michigan Ave.” The first hex digit refers to the last line information, the second hex digit refers to the first street in the intersection, and the third hex digit refers to the second street in the intersection. Note: The USPS does not allow intersections as a valid deliverable address
`Yhhh`	Same as `Xhhh`, but an alias name record was used for one or both streets.
`Z`	No address given, but verified the provided ZIP Code.

Match Codes for No Match - Definitions for "Ennn" return codes

The table below describes the values returned when the application cannot find a match or an error occurs.

Code	"nnn" values	Description
`Ennn`		Indicates an error, or no match. This can occur when the address entered does not exist in the database, or the address is badly formed and cannot be parsed correctly. The last three digits of an error code indicate which parts of an address the application could not match to the database.
	`nnn = 000`	No match made.
	`nnn = 001`	Low level error.
	`nnn = 002`	Could not find data file.
	`nnn = 003`	Incorrect GSD file signature or version ID.
	`nnn = 010`	No city and state or ZIP Code found.

	`nnn = 012`	Input city not in the directory.
	`nnn = 013`	Input city not unique in the directory.
