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 |
---|---|
|
Same as |
Chh |
Street address did not match, but located a street segment based on the input ZIP Code or city. |

Matched to a small town with P.O. Box or General Delivery only. |
Ghhh |
Matched to an auxiliary file. |

Qhhh |
Matched to USPS range records with unique ZIP Codes. CASS rules prohibit altering an input ZIP if it matches a unique ZIP Code value. |
Rhhh |
Matched to a ranged address. |
Shhh |
Matched to USPS data. This is considered the best address match,
because it matched directly against the USPS list of addresses.

when the matched address has a blank ZIP + 4. |
Thhh |
Matched to a street segment record. |
Uhhh |
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. |

Definitions for Extended Match Code (3rd hex digit values)
Extended additional information is returned about any changes in the house number, unit number and unit type fields in the matched address, as well as whether there was address information that was ignored. This additional information is provided in a 3rd hex digit that is appended to match codes for address-level matches only - A, G, H, Q, R, S, T or U (see Match Codes).
- Intersection matches, see Definitions for 1st-3rd hex digit match code values
- Extended Match Codes, see the table below.
"Address information ignored" is specified when any of these conditions apply:
- The output address has extra information (for example, a mailstop) in the address line.
- The output address has a second address line (
AddressLine2
). - The input address is a dual address (two complete addresses in the input address). For example, "4750 Walnut St. P.O Box 50".
- The input last line has extra information that is not a city, state or ZIP Code, and is ignored. For example, "Boulder, CO 80301 USA", where "USA" is ignored when matching.
