What Byteplant Address Validator is
Byteplant Address Validator checks postal addresses against reference data to assess deliverability and suggest corrections. It checks whether street, house number, postal code, and city combinations are valid and correctly formatted, with validation and correction available in more than 240 countries and territories. Its APIs can return autocomplete suggestions for freeform searches, provide geocoding, identify duplicate records, and process up to 100,000 addresses in one asynchronous bulk request. Rooftop-accurate coordinates are available when geocoding is enabled. A free account includes 100 checks and corrections without payment details or an automatic subscription. Purchased credits do not expire; monthly subscriptions add credits automatically, while pay-as-you-go credits are purchased once. Address checks consume 1.0, 2.5, or 5.0 credits depending on region, and geocoding uses additional credits. Listed integrations include Zapier, WordPress, jQuery, Node.js, CRM, and e-commerce systems. Byteplant says data is handled in the EU and personal information is deleted within 14 days. It states a 99.9% availability guarantee and typical API response times of 125 milliseconds. It cannot establish whether a person has moved; a physically existing former address may still be valid.
