Summary

Socure argues that reliable address verification is essential to Customer Identification Program and anti-money-laundering compliance because PO boxes and commercial mail receiving agencies can prevent financial institutions from locating customers. Its testing found that even USPS tools can omit or misclassify postal facilities, illustrated by a New Mexico post office that appeared as an ordinary street address and was not returned by USPS API or nearby-facility searches. In response, Socure developed a method that cross-references multiple data sources, iterates through postal codes and location identifiers, evaluates carriers such as FedEx, UPS, and DHL, and uses its identity graph to correct commercial classifications caused by missing unit numbers. The company says this approach reduced false positives for PO box and CMRA flagging from 0.5% to zero, reinforcing its view that verification systems must account for the differing strengths and limitations of ostensibly authoritative data sources.
