Features

Everything You Need

Powerful features designed for enterprise-grade performance and compliance

Format Standardization

Convert any phone number input to the international E.164 standard format automatically. Handles local formats, missing country codes, and formatting variations from 240+ countries.

Carrier Lookup

Identify the current network operator serving the phone number in real-time. Carrier data is sourced directly from number plan administrators and updated continuously.

Number Type

Classify numbers as mobile, landline, VoIP, toll-free, or premium rate. VoIP detection is critical for identifying numbers commonly used in account fraud and synthetic identity schemes.

Country Detection

Identify the country of origin and geographic region for any phone number. Detect numbers that claim a domestic format but originate from foreign carriers or virtual providers.

Porting Check

Detect numbers that have been ported between carriers, including the original and current operator. Recent porting activity can be a risk signal in fraud prevention workflows.

Active Status

Verify whether a phone number is currently active and capable of receiving calls and messages. Avoid wasting SMS credits on disconnected or deactivated numbers.
