Address Verification

can identify Non-Delivery Days (NDD) addresses when you verify addresses in certified mode. NDD addresses do not receive mail on one or more days of the week.

To identify NDD addresses, Address Verification introduces the

NDD

field. The

NDD

field contains a seven-digit string that represents the days of the week from Sunday through Saturday. Each position in the string represents a different day.

Address Verification returns the first letter of a weekday in the corresponding position in the

NDD

field if the address does not receive mail on that day. Address Verification returns a dash symbol in the corresponding position otherwise.

For example, consider the following address:

Address Verification returns an NDD value of

S----FS

, which indicates that the business does not receive mail on Sunday, Friday, and Saturday.

To identify NDD addresses, Address Verification reads the

USA5C129.MD

and

USA5C130.MD

database files.

Address Verification

can provide additional information on why an address fails delivery point validation. Address Verification returns the information as a numeric code in the

DSF2_NOSTATS_REASON

field.

When an address does not yield a positive DPV result, Address Verification returns a value of Y in the

DSF2_NOSTATS

field. The

DSF2_NOSTATS_REASON

field contains values in the range 1 through 5 that indicate the reason for the Y result.

The following table describes the codes that Address Verification can return in the

DSF2_NOSTATS_REASON

field:

To identify NoStat Reason addresses, Address Verification reads the

Address Verification

can identify Throwback addresses when you verify addresses in certified mode. A Throwback address is a valid street address for which the USPS forwards mail to a Post Office Box. Address Verification populates the

DPV_THROWBACK

field to indicate the Throwback status of the address.

The

DPV_THROWBACK

field can contain Y or N or the field can be empty. Address Verification returns Y in the

DPV_THROWBACK

field for a Throwback address and returns N otherwise.

To identify Throwback addresses, Address Verification reads the

USA5C132.MD

database file.

Address Verification

can identify an address that represents a valid delivery point but to which the sender has added an unrecognized trailing character in the house number field. If the address can yield a valid delivery point without the trailing alpha character, Address Verification adds the value TA as a DPV footnote.

For example,

Address Verification

might return a DPV footnote value of AAN1TA for a high-rise address and a DPV footnote value of AACCTA for a street address.
