Case Study: The City of Tempe achieves standardized, accurate addresses and reduced undeliverable mail with Melissa Address Verification

City of Tempe Utilizes Address Validation Tool to Build Data Warehouse

The City of Tempe faced inconsistent and often inaccurate address records across multiple departmental systems, causing undeliverable mail, wasted postage, and limited analytical capabilities. To standardize contact data and meet USPS CASS standards, The City of Tempe deployed Melissa's Address Verification solution.

Melissa integrated Address Verification into the city’s custom application and ETL/data warehouse, validating addresses at point-of-entry and in batch to the physical delivery point and appending CASS‑certified postal codes. The result was fewer undeliverable mailings, measurable savings on postage and shipping, improved cross-system data relationships for analytics, and a foundation for future EGIS spatial analysis.
