Calculating Mailability Scores

Calculating Mailability Scores

Address Verification considers multiple factors when it calculates the mailability score. Address Verification bases the calculations principally on the Process Status Code value and the Element Result Status value for the address. Other factors that influence the mailability score include the granularity of the reference data for the country and the postal relevance of the address values.
For example, if Address Verification cannot verify input elements such as street and house number because the data is absent from the reference database, Address Verification reduces the mailability score value.
Additionally, country-specific factors influence the mailability score. For example, when you verify United States addresses, the mailability score calculations considers deliverability factors such as the R777 status of each address. An R777 (phantom route) address is an address in a location that is served by P.O. Box delivery although the mailing address contains valid street information. In such cases, Address Verification might assign an address a Process Status value of V4 or C4 and a Mailability Score value of 1, because the USPS does not deliver to the street address.

Mailability Scores in India

The following table describes the relationship between Process Status values and Mailability Score values in India addresses:
Process Status
Mailability Score
I1
0 If the address cannot be found in the reference database.
I2
1 If the address cannot be corrected satisfactorily from the reference database.
I3, I4
2 If the input address matches more than one address in the reference data.
C2
2 If street delivery information is expected but absent from the input address.
C3
3 If some parts of the address validate against the reference database, but corrections are necessary. Also, some input elements, such as an organization name, are not found in the reference database.
C4
4 If every part of the address validates against the reference database, but some corrections are necessary.
V2
4 If the address contains street delivery information that cannot be validated against the reference database.
2 If street delivery information is expected but absent from the input address.
V3, V4
5 If every part of the input address validates against the reference database.
4 If the input address does not contain street delivery information, and street delivery information is not required. This can be adequate for rural addresses.

Mailability Scores in Japan

The following table describes the relationship between Process Status values and Mailability Score values in Japan addresses:
Process Status
Mailability Score
I1
0
V2
1 For example, the reference database does not contain street delivery information but contains Chome and Ban information for an address.
I3, I4
2
C2
3 For example, the input address contains Chome and Ban information, but comparable Chome and Ban information is absent from the reference database.
C4
4
V3, V4
5

Mailability Scores in the United States

The following table describes the relationship between Process Status values and Mailability Score values in United States addresses:
Process Status
Mailability Score
I1, I2
0
I3, I4
1
C1, C2
2
C3
3 or 4 For example, the input address contains sub-building data, but comparable sub-building data is absent from the reference database.
V1, V2
4
V3, V4, C4
3 For example, neither the input nor the reference data includes a house number for the address.
4 For example, default high-rise match.
5
Address Verification can downgrade the mailability score for a United States to 1 in certified mode if the input house number is not found in the Delivery Point Validation reference data.

Mailability Scores in the Rest of the World

The following table describes the general relationship between Process Status values and Mailability Score values in many other countries:
Process Status
Mailability Score
I1
0
I2
1
I3, I4, C2
2
C3 (and sometimes C4)
3
C4, V2
4
V3, V4

Mailability Scores in Certified Modes

Processing in certified mode may result in different mailability scores than batch or interactive mode, because certified databases can contain additional data points against which to verify the input.

Local Factors in Mailability

The mailability score is a general estimate of deliverability. Local factors can influence the likelihood of successful delivery. An incorrect address due to missing sub-building data might have a good chance of correct delivery in many countries. Conversely, a United States address might find a fully valid match in the reference database, but the address might also appear on a non-delivery table from the USPS. In such a case, the United States address returns a mailability score of 0.
