MNRL Check API
Check whether an Indian mobile number appears on the Mobile Number Revocation List, flagging disconnected numbers before they are reassigned.
What the MNRL Check API does
MNRL Check tests a number against the Mobile Number Revocation List, the register of numbers disconnected by operators. Revoked numbers are eventually reissued to new subscribers.
This is the check that prevents a quietly serious failure: continuing to send OTPs, statements or transaction alerts to a number that now belongs to a stranger. Screening your base against MNRL turns that from an incident into routine hygiene.
Where teams use the MNRL Check API
Screening a customer base before an OTP or alert campaign
Preventing sensitive messages reaching a reassigned number
Cleaning stale contact data in a CRM
Reducing wasted spend on undeliverable messages
Frequently Asked Questions (FAQs)
What does a hit mean?
The number was disconnected and may already have been reissued. Stop sending to it and re-verify the customer through another channel.
How often should I run it?
Periodically across the base, and before any campaign carrying personal or financial information.
Does it say who holds the number now?
No. It reports revocation status only. Use mobile verification to establish who currently controls a number.
