A phone call from “1600-XXXXXXXX” claiming to be your insurer is meant to be genuine. From 15 February 2026, the Telecom Regulatory Authority of India (TRAI) requires every IRDAI-regulated insurer and intermediary to use the 1600-series for service and transactional calls. So a real call about your policy or claim should now come from a 1600 number, while a 10-digit mobile number claiming to be “your insurance company” is a red flag.
Short on time? Jump to the checklist below to tell a genuine call from a scam in 20 seconds.
TRAI issued a direction in December 2025 ordering all entities regulated by the Insurance Regulatory and Development Authority of India (IRDAI) to adopt 1600-series numbers for calls to customers. The deadline was 15 February 2026. This covers insurers and their intermediaries, such as agents and corporate channels.
The goal is simple: let you trust the number on your screen. Fraudsters often pose as insurance staff to push fake policies, “bonus release” fees or lapse-revival charges. By tying genuine service calls to a recognisable number band, TRAI aims to curb spam and cut voice-call fraud.
This is not the first such move. RBI-regulated and SEBI-regulated entities, including banks, already shifted their service and transactional calls to the 1600-series. Over 570 entities had adopted the series even before the IRDAI deadline.
Run any “insurance” call through this list before you act:
Different call types now sit in different number bands. Knowing the band helps you read the call before you pick up.
| Number series | What it means | Who uses it |
|---|---|---|
| 1600-series | Service and transactional calls: policy servicing, premium reminders, claim updates | Banks, insurers, other RBI, SEBI and IRDAI regulated entities |
| 140-series | Promotional and telemarketing calls | Registered telemarketers and sales channels |
| 10-digit mobile claiming to be your insurer | Treat as unverified | Often used by fraudsters impersonating staff |
Note: a 1600 number is a strong signal of a genuine entity, but you should still never share OTPs or pay fees on any call.
A genuine 1600-series call is for transactional contact only. That includes:
Promotional pitches and pure sales calls are supposed to come from the 140-series instead. So if a “1600” caller launches into a hard sell for a brand-new policy, stay cautious and verify.
Dr. Shrawan Kumar Pathak got a call in March 2026 from a 10-digit mobile number. The caller said his health policy had lapsed and asked for an OTP to “reactivate” it. He remembered that genuine insurer service calls now come from 1600 numbers and that no real insurer asks for an OTP. He hung up, called the number printed on his policy, and confirmed the policy was active. The “reactivation” call was a scam.
The Right to Information Act 2005 lets you ask TRAI and other public authorities for the policy and records behind this rule. RTI is for documents and policy, not for recovering money lost in a specific fraud.
You can file an RTI with TRAI to obtain:
A clean RTI request gets you a reply within 30 days. If the reply is missing or evasive, file a first appeal within 30 days of that deadline. The AI RTI Drafter helps you word the request, the Timeline Tracker gives the exact reply and appeal dates, and the First Appeal Builder drafts the appeal if you get no answer. Check a confusing reply with the PIO Reply Checker. For the full method, read The RTI Playbook and the RTI Act 2005.
A 1600 number is a strong sign the caller is a regulated entity making a service call. It is not a blank cheque. Never share an OTP, card number or password, and never pay a fee on any call, even a 1600 one. Verify on your official policy number if anything feels off.
TRAI set 15 February 2026 as the deadline for all IRDAI-regulated insurers and their intermediaries to use the 1600-series for service and transactional calls. The direction was issued in December 2025.
Yes. RBI-regulated and SEBI-regulated entities, including banks, already moved their service and transactional calls to the 1600-series. The December 2025 direction extends the same approach to IRDAI-regulated insurers.
Promotional and telemarketing calls use the separate 140-series, not the 1600-series. So a hard sales pitch from a “1600” number is a reason to slow down and verify before you agree to anything.
No. Genuine financial-service calls never ask for OTPs, full card numbers, CVV or passwords, regardless of the number band. Treat any OTP request as fraud. Hang up and call the official number on your policy.
Use the TRAI DCA app or the Do Not Disturb service to report unsolicited or fraudulent calls. If you lost money or shared sensitive details, call 1930 or file a complaint at cybercrime.gov.in and inform your telecom provider.
No. RTI gets you records and policy information from public authorities like TRAI. To recover money or pursue a fraudster, use the cyber-crime helpline 1930 and cybercrime.gov.in, and report to your insurer and telecom provider.
More than 570 entities had adopted the 1600-series before the IRDAI deadline. With the December 2025 direction now mandatory, the series applies across IRDAI-regulated insurers and intermediaries as well.
