DEFINiTION

What is address verification?

Address verification is the process of running addresses against an authoritative database – such as USPS in the US – and validating the realness of the information. This process verifies that the address is a mailable, accurate, and valid location within the country for delivering mail.

The process usually starts with address standardization, then goes on to parsing, geocoding, and formatting, etc.

What DME’s address verification can do for you?

DME, a CASS-certified solution, parses address fields into its respective components such as street name and number, zip code, city name, state, and country, etc. Next, it matches each of them against the standardized USPS® database to validate their accuracy, and constructs the address in a way such that it follows the standardized address format.

DME allows you to compute the latitudinal and longitudinal geocodes for any given address, as well as identify the 5-digit zip code along with the 4-digit route within delivery area. Furthermore, DME profiles address information and plots pins of address on the map to give you exact coordinates of the addresses.
With DME’s extensive address verification capabilities, you can not only verify an address’s existence against an official address database, but also check whether the address is residential or business, confirm it right down to the apartment and suite number, and add secondary information to improve mail delivery.

Address verification software checks whether address information is complete, correctly formatted, and recognized by an authoritative postal reference source. It can parse address components, correct formatting inconsistencies, append missing postal information, and flag records that require review. Organizations use it to improve mailing accuracy, customer records, deliveries, analytics, and regulatory communications.

Address standardization converts addresses into a consistent postal format. Address validation compares the standardized information against an authoritative reference source. Address verification determines whether the address can be recognized and used for its intended purpose. Address matching identifies records that refer to the same location despite spelling or formatting differences. Geocoding assigns geographic coordinates to an address. In practice, vendors sometimes use “validation” and “verification” interchangeably.

Address validation software first parses an address into components such as house number, street, city, state, and postal code. It then cleans and standardizes those components before comparing them with postal reference data. Depending on the available information, the software may correct formatting, add missing postal codes, identify incomplete addresses, and return validation details for review. Learn more about the address validation process.

Address matching software compares standardized address components instead of relying only on an exact full-address match. It can recognize differences involving abbreviations, punctuation, unit numbers, misspellings, reordered components, and ZIP Code formats. Matching rules can also combine address information with names, phone numbers, or account identifiers to determine whether two records represent the same household, customer, or location. Learn more about address data matching.

CASS certification allows USPS to evaluate the accuracy of address-matching software in applying postal information such as Five-Digit ZIP Codes, ZIP+4 Codes, delivery points, and carrier routes. Certification measures the software’s address-matching capabilities; successful results still depend on the completeness, quality, and timeliness of the source data. Learn more about CASS-certified address validation software.

Yes. DataMatch Enterprise can standardize address records, assign Five-Digit ZIP Codes and ZIP+4 Codes when suitable reference information is available, and generate latitude and longitude values for geocoding. These outputs can support mailing operations, geographic analysis, householding, service-area analysis, and location-based record matching.

Evaluate the geographic coverage, reference-data sources, parsing and standardization capabilities, ZIP+4 and geocoding support, batch-processing capacity, matching and deduplication features, integration options, and the clarity of returned validation results. Organizations using address data for U.S. mailing operations should also confirm whether the software holds current CASS certification.
