Minimal, Focused Payload

A lightweight response keeps this cheap to run before a heavier verification step.

Know the Number Before You Message It

Veriqos Telco Lookup Basic API returns a mobile number's operator, telecom circle and line type (prepaid or postpaid) in under 150ms, a fast, lightweight check to run before spending on OTP delivery or flagging suspicious signups.

Cut Wasted OTP Spend

Screening out invalid or unreachable numbers before sending an OTP avoids paying for messages that will never be delivered.

Flag Suspicious Signups

Unusual operator or line-type patterns can be an early signal worth combining with other fraud checks.

Compliance

With strict security controls and reliable verification logic, the Telco Lookup Basic API keeps every check safe at every step.

Protected Data Handling: Mobile number details are encrypted in transit and at rest throughout the verification process.
Trusted Source Checks: Every result is validated against live telecom records rather than cached or third-hand data.

What Our Clients Say

Teams in mobility, IT services, hiring, education and technology use Veriqos Technologies to verify people and businesses before they onboard them.

Driver onboarding was our biggest bottleneck. DL, Aadhaar and RC checks now run in one flow, so a new driver can start the same day.

Driver Onboarding Team

Freelancers and clients are verified before any project begins. PAN and GST validation came through a single API, so we never had to build it.

Platform & Trust Team

Background verification was the slowest step in every placement. Automating identity and employment checks cut our overall turnaround by roughly sixty percent.

Resourcedekho

Verification Team

Vendor onboarding had to be quick without being careless. The API-first setup let us plug the checks straight into our existing internal workflow.

Using the telco lookup API before you send messages

The telco lookup API tells you the operator, circle and line type of a mobile number before you spend money on an OTP or SMS. Run the telco lookup API as soon as a number is entered, so you can catch numbers that cannot receive messages and ask the user to correct them straight away.

Line type matters too: the telco lookup API helps you decide how to treat landline or unusual numbers in a mobile-first flow. Keep the telco lookup API result with the signup record, and refresh it if the customer changes their number later.
