AddressZen vs Informatica Address Verification

AddressZen provides address lookup, autocomplete, validation, and verification for US and international addresses through an API, browser extension, and web interface. Its validation can normalize formatting, expand street and city abbreviations, add missing ZIP+4 details, and correct typos. It advertises coverage in 240+ countries and support for 60+ languages, with local address data that includes USPS sources for US verification and details such as apartment and suite numbers. Suggestions are real-time and matching accounts for typos. Developers can use JavaScript libraries, a React component, or a REST API; listed integrations include Zapier, Adobe Commerce, WooCommerce, and form tools. Batch validation and API key controls are available, including lookup limits, allowed URLs, and configurable transaction-log retention. The free plan includes 1,400 verified addresses for one year. The Address bundle is $1,000, paid once for 55,000 verified addresses. Billing is per verified address, with no setup fees or monthly commitment. The API reference limits each IP to 30 requests per second, with a separate autocomplete limit.
