Address precision detailed examples

The following examples represent the data as it is compared along with the resulting address precision scores.

The first address represents the existing address in the entity database, and the second address is the incoming address.

Precision Level 1 - Street match with all parts, postal+4 different.

This case shows two addresses that are on the same street, but are distinct addresses. One address in on the north end of the street, and the other is on the south end. The only differences between these two addresses are the Zip+4 values.

STREET CITY STATE POSTAL
123 N Main St Fairmount IN 46928-1655
123 S Main St Fairmount IN 46928-1924
Note: Precision level 1 represents a special case where address information might be the same with the exception of a North/South or East/West street designation. On the surface, these addresses might seem to require a resolution. However, they must not be resolved to each other because they are in fact different addresses. Because this seemingly strong case for address resolution is in fact a strong case for not resolving the addresses to each other, the value of this scenario is placed at the bottom of the scale (1) to prevent the addresses from being resolved.

Precision Level 2 - Street match with all parts differing.

This example shows two addresses with the same street information but different city, state and postal information. The second address is obviously a mistake (perhaps intentional) because postal codes in Nevada all start with 89.

STREET CITY STATE POSTAL
123 E Main St Fairmount IN 46928
123 S Main St Las Vegas NV 46999

Precision Level 3 - Street match with -2 difference modifier.

In this example, only the street information matches. No state information is provided in the incoming address, and the city and postal information are conflicting.

STREET CITY STATE POSTAL
123 E Main St Delphi IN 46923-1522
123 E Main St Fairmount   46928

Precision Level 4 - Street match with -1 difference modifier.

This example shows two addresses with the same street and state information but conflicting city and postal information.

STREET CITY STATE POSTAL
123 E Main St Delphi IN 46923-1522
123 E Main St Fairmount IN 46928-1924

Precision Level 5 - Street match with 0 modifier (baseline)

In this example, only the street information is provided in the incoming address. Even though it does not contain city, state, or postal information, the match receives the baseline address precision score (5). The precision score reflects the missing parts (not to be confused with conflicting parts as missing parts are not scored).

STREET CITY STATE POSTAL
220 JEFFERSON BUFFALO IA  
220 Jefferson St.      

Precision Level 6 - Street match with +1 matching modifier.

This example shows an incoming street address without state or postal information but the same street and city information. The incoming address is likely the correct address but is missing data.

STREET CITY STATE POSTAL
220 Washington Syracuse NY  
220 Washington Sq. Syracuse    

Precision Level 7 - Street match with +2 matching modifier

This example shows matching street, city, and simple postal information, but no state information is provided in the incoming address.

STREET CITY STATE POSTAL
220 JEFFERSON BUFFALO IA 52728
220 Jefferson St. Buffalo   52728

Precision Level 8 - Street match with all parts, postal +4 missing

Here two addresses are the same, but address hygiene was unable to validate the addresses so they did not receive a Zip+4.

STREET CITY STATE POSTAL
220 JEFFERSON BUFFALO IA 52728
220 Jefferson St. Buffalo IA 52728

Precision Level 9 - Exact match (street with all parts). This selection means that all parts of the address match including the postal +4

In this example, two addresses share the same street address, city, state and Zip+4. As a result, the compared addresses receive the highest address precision score.

Note: This does not work on international postal codes where postal +4 are not used.
