July 20, 2021 - PROVO, UTAH - SmartyStreets, a leader in location data intelligence, announces the release of the new US Address Verification - Enhanced Matching. Enhanced matching successfully verifies the messiest of addresses and includes 15 million additional valid addresses not found in the USPS address database.

The new enhanced matching engine successfully validates and corrects more ill-formatted addresses than ever before. Corrections include greater varieties of misspellings, redundant text, incomplete addresses, and sloppy data. Recently, 2 million low-quality addresses were processed using the new engine. It found over half a million matches that previously failed when processed by more conventional address verification engines.

“Addresses that are too messy for other address verification software must be corrected manually,” explained Jonathan Oliver, Founder of SmartyStreets. “Depending on the size of your databases, a matching improvement like what we’ve seen with our new enhanced matching engine may lead to saving thousands of man-hours.”

Messy addresses are also prone to result in false positive matches. False positives happen when addresses that shouldn’t match get matched anyway. Increasing match rates without increasing false positives is a major challenge.

“False positives are dangerous to organizations because they’re bad data in your system; bad data that is disguised as good data. And, bad data costs you money.” Oliver continued. “We managed to increase our match rates while keeping our false positive rate as low as ever. Users get more matches without increased risk of bad data.”

By combining SmartyStreets enhanced matching capabilities with 15 million additional addresses that aren’t included in the postal address database, match rates improve even more. Users get newly available address metadata points on these non-postal addresses that lead to improved spatial analysis and data quality.

US Address Verification - Enhanced Matching also comes with the extremely high processing speeds SmartyStreets is known for. Speeds up to 580,000 records per second mean that SmartyStreets can validate all 175 million US delivery points in about five minutes. SmartyStreets also features enterprise plans that are even faster. The engine is well-documented and available through an API, CLI, and a suite of web-based tools.

Because who doesn’t love juggling one more thing during the holiday season…? A major shift in the address-verification landscape is approaching at the beginning of the new year. On January 25, 2026, the United States Postal Service (USPS) will officially retire its long-standing Web Tools APIs, a free API that previously allowed for approximately 5 address lookups per transaction. This includes the legacy USPS Address Information APIs that many organizations have depended on for years. Under USPS’s new API structure, the default quota for many services, including the Addresses API, is 60 requests per hour.
