Validity Checks
Confirm a number is properly formatted, allocated and plausible before using it.
Number Intelligence
Know the number before you dial or deliver.
Carrier lookup, line-type detection and number validation — so your calls route correctly, your messages reach handsets, and your data stays clean.
Overview
Better data in, better outcomes out
A surprising share of communications cost is wasted on bad numbers: disconnected lines, landlines receiving SMS, ported numbers routed to the wrong carrier. Number intelligence closes that gap by telling you what a number actually is before you spend money on it.
Vireon's lookup services return validity, line type, current carrier and portability information in real time through a simple API — suitable for point-of-entry validation, batch database cleaning and pre-routing checks.
The same data improves compliance and customer experience: don't SMS landlines, don't call numbers that can't ring, and route traffic based on where a number lives today, not where it was issued.
