What it is

Byteplant Address Validator checks postal addresses against reference data to assess deliverability and suggest corrections. It checks street, house number, postal code, and city combinations for validity and formatting, with coverage across more than 240 countries and territories. Its APIs provide autocomplete suggestions from freeform searches, geocoding, duplicate identification, and asynchronous bulk verification for up to 100,000 addresses in one 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, and a free trial is listed. Credits purchased through pay-as-you-go do not expire; monthly subscriptions add credits automatically and unused credits roll over. Address checks use 1.0, 2.5, or 5.0 credits according to region, with additional credits for geocoding. Integrations include Zapier, plugins for WordPress, jQuery, and Node.js, plus CRM and e-commerce systems. Byteplant says data stays in the EU and personally identifiable end-user information is deleted within 14 days. It states a 99.9% availability guarantee and typical API responses within 125 milliseconds. The service cannot determine whether a person has moved; an existing former address may still validate.
