Melissa Global Address Verification vs UPU POST*CODE API

Melissa Global Address Verification checks and corrects billing and shipping addresses at entry or in batches, covering more than 250 countries and territories. It standardizes results for mailing labels according to local country standards, returns parsed address components, and can append latitude and longitude coordinates. Addresses can also be transliterated to or from the native language of the input country. The service is available through public cloud or on-premise deployment; for on-premise use, its library and data files sit on the customer’s own servers. Listed integrations include Microsoft SSIS, Dynamics CRM, Excel, Pentaho PDI, Talend, and Salesforce. Melissa says its public cloud is hosted in a secure, private environment, undergoes SOC 2 audits, and stores no PII data. Its address page lists HIPAA/HiTrust and SOC 2 certification, plus CCPA and GDPR compliance. The pricing page labels plans CASS and DPV Certified and lists 90 day free trials with subscriptions, as well as unlimited technical support. The free GAV plan includes 250 records per month. GAV Sub 1K costs $40 a month for 1,000 records.

UPU POST*CODE API verifies international addresses using official locality names and postcode data from UPU member countries. Its checks cover a country’s postcode format, whether a postcode matches a locality, postcodes associated with a locality, and localities associated with a postcode. LocalityLike suggests official locality names and postal regions from the beginning of a partial locality input. The API is intended for designated postal operators, businesses, and individuals handling international addresses, including customs declarations, web shops, user platforms, and ERP systems. It can run as a CDS plugin, through the CDS API gateway or other middleware, or inside postal websites and local applications. Development guidance covers HTML, web applications, JavaScript form handling, and sample code for jQuery and Python. Documentation includes tutorials, quick-start guides, and developer tooling. UPU says response time is under one second and performance can be adjusted to expected call volume. Pricing is on request, with a free trial available by contacting UPU.
