Abstract Phone Validation API vs Veriphone

Abstract Phone Validation API has no write-up on Specifiction yet; its figures are above.

Veriphone validates phone numbers through an API or a web CSV workflow, returning validity, carrier, line type, and country information. The service says it supports 243 countries and territories and can format numbers as E.164, international, or local. Validation checks whether a number follows its country’s official numbering plan; it does not confirm that the phone is currently switched on. The instant API uses a GET request and returns JSON, while CSV uploads can be downloaded with results for each row. Current Carrier Lookup consults national portability registries and can return original carrier, current carrier, and ported status; a resolved lookup costs 10 credits. Standard validation costs 1 credit. The Free plan is free and includes 1,000 credits each month. One-time packages range from $24, paid once for 10,000 credits to $999, paid once for 5,000,000 credits; purchased credits do not expire. Veriphone also offers Zapier and Make integrations. API numbers are processed in memory, while infrastructure request URLs are retained for 30 days and CSV uploads remain until deleted or may be removed after 90 days.
