Match Codes

The geocoder returns match codes indicating the address portions that matched or did not match to the database.

If the geocoder cannot make a match, the match code begins with E and the remaining digits indicate why the address did not match. For a description of the Ennn codes, see Match Codes for No Match. The digits do not specifically refer to which address elements did not match, but rather why the address did not match.

The following table contains the match code values. For a description of the hex digits for the difference match codes, see Match Hex Digits.

Code

Description

Ahh

Same as Shh, but indicates match to an alias name record or an alternate record.

Chh

The street address did not match, but the geocoder 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.

Gxx

Matched to an auxiliary file.

Hhh

The house number was changed.

Jhh

Matched to a user-defined dictionary.

Nxx

Matched to the nearest address. Used with reverse geocoding. The following are the only values for N:

NS0
Nearest street center match (nearest street segment interpolated)
NS1
Nearest unranged street segment
NP0
Nearest point address
NX0
Nearest intersection

P

Successful reverse APN lookup.

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. CASS mode returns an E023 (multiple match) error code.

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 .
