What Byteplant Data Validation is
Byteplant Data Validation provides cloud services for validating and enriching postal addresses, email addresses and phone numbers, with web and API access. Address-Validator checks and corrects addresses in 240 countries, offering standardization, autocomplete, bulk processing, deduplication, diagnostics and rooftop-level geocoding. It checks whether an address physically exists and is correctly formatted, but not whether someone has moved. Email-Validator checks DNS and MX records, disposable and misspelled addresses, SMTP availability, mailbox existence, catch-all behavior and greylisting; the bulk API accepts up to 100,000 addresses per request. Phone Validator offers validation, bulk verification, deduplication, formatting, location information and line-type detection. Integrations include plugins for WordPress, Drupal, jQuery and Node.js, plus Zapier and an MCP server. An Address-Validator free account includes 100 checks and corrections without payment details or automatic subscription. Byteplant says credits do not expire and validation data is deleted within 14 days. The company was established in 2003 and is headquartered in Neuendettelsau, Germany.
Good
- Address checks cover 240 countries.
- Bulk email API accepts up to 100,000 addresses.
- Free address account includes 100 checks.
- Purchased credits do not expire.
Watch out
- Prices depend on region and volume.
- Address validation cannot determine whether someone moved.
Who it suits
It suits teams that need address, email or phone checks in websites, applications or bulk data workflows. Address validation may help with checkout, logistics, CRM maintenance and database cleanup, but it cannot confirm whether a person has moved.
Verdict
Byteplant combines address, email and phone validation with several integration routes and a limited free address allowance. Consider its address-validation limitation and the pricing variables when assessing fit.
