In their own words
Hopewiser Address Validation
Hopewiser Address Validation checks UK and international addresses in real time and provides postcode lookup, with the stated aim of reducing errors, failed deliveries, and manual corrections. It offers correction, standardisation, autocomplete, and batch validation. UK lookup uses Royal Mail’s Postcode Address File, described as containing 1.8 million postcodes and 31.9 million addresses; Hopewiser says its international datasets cover 250 countries. Other available data sources include Eircode, Companies House, Ordnance Survey AddressBase Premium, and the National Statistics Postcode Directory. Cloud access includes CRM integrations, a REST API, a JavaScript client, usage reports, and an online data-cleansing tool. Listed integrations include Microsoft Dynamics CRM, Sage CRM, Salesforce, WooCommerce, WordPress, and IBM WebSphere. The on-premise option processes address data on a customer’s own servers or private cloud, keeping it within the local network. Its annual licence allows unlimited processing, with pricing typically tiered by production server environments or CPU cores. Online portal lookups cost what you agree with the maker; software licences require contacting Hopewiser for pricing.
UPU POST*CODE API
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.
