Mobile Number Prepaid / Postpaid Check API

What is Mobile Number Prepaid / Postpaid Check?

The Mobile Number Prepaid / Postpaid Check from JustSwitch lets product teams integrate mobile numbers in real time through a single REST integration. Designed for the Telecom / IMEI lane, it removes manual checks, reduces drop-offs in onboarding funnels, and returns structured JSON that your risk engine, CRM, or core banking system can consume instantly.

Every request is authenticated with API keys, logged for audit, and routed through regulated partner rails where required. Responses follow a consistent `{ ok, data, message }` envelope so you can ship once and reuse the same error-handling patterns across all JustSwitch endpoints.

Whether you run a lending app, payment aggregator, or enterprise ERP, Mobile Number Prepaid / Postpaid Check scales horizontally with rate limits tuned for burst traffic during campaigns. IMEI verification via CEIR/Sanchar Saathi requires proper authorised integration — not public scraping.

Developers choose JustSwitch for Mobile Number Prepaid / Postpaid Check because we aggregate multiple upstream providers behind one contract, one wallet settlement, and one support desk — so you launch faster while your compliance team retains full audit visibility through dashboard logs and exportable reports.
