Decoding the Numbers
The Telecom Regulatory Authority of India (TRAI) has established specific number series to help you identify the purpose of a call. The 140 series is officially designated for promotional and telemarketing calls. In theory, any call from a number starting
with '140' is from a business trying to sell you something. However, this series has been widely misused, leading many to associate it with spam. To address this, a new 160 series has been introduced for service and transactional calls. This includes important updates you might actually want, like bank alerts, delivery confirmations, and payment reminders. For example, calls from financial institutions like banks will start with '1601'. This separation is designed to make it easier for you to distinguish a marketing pitch from a crucial update.
Why They Are Being Flagged
The primary reason these numbers are being flagged is the overwhelming rise in spam and financial fraud. Scammers frequently use 10-digit mobile numbers to impersonate officials from banks, government agencies, or other legitimate organisations to trick people into revealing sensitive information. The new regulations aim to curb this by forcing commercial communications through identifiable channels. Telecom operators and TRAI are using Distributed Ledger Technology (DLT) and AI-powered filters to enforce these rules. Legitimate businesses must register on the DLT platform to use these numbers, creating a verifiable trail. Calls from unregistered numbers or those violating the rules—like a promotional call not using the 140 series—are automatically flagged or blocked. This helps protect consumers who have registered for the Do Not Disturb (DND) service and creates a more transparent communication environment.
The Real Danger: Financial Scams
While unwanted marketing is an annoyance, the more serious threat is financial fraud. Scammers are becoming increasingly sophisticated, using tactics like digital arrest, where they pose as law enforcement officials to extort money. They might create a sense of urgency, claiming your bank account will be blocked, or try to lure you with fake KYC update requests, job offers, or lottery wins. The introduction of the 160 series for verified service calls from the financial sector is a direct response to this threat. The goal is to create a 'trust stamp'; if you receive a call from a bank that does not start with '1601', it should be treated with extreme caution. This makes it much harder for fraudsters to impersonate legitimate financial institutions and dupe unsuspecting citizens.
How You Can Fight Back
You have several tools at your disposal to combat spam and fraudulent calls. The most effective first step is to register for the National Do Not Call (DND) registry. You can do this by sending an SMS with 'START 0' to 1909 or through your telecom provider's app, like MyJio, Airtel Thanks, or Vi. For reporting suspected fraud, the government has launched the Chakshu portal on the Sanchar Saathi website. Here, you can report suspicious calls, SMS, and even WhatsApp messages related to potential financial fraud or impersonation. TRAI also encourages users to download its DND app to report unsolicited commercial communications directly. Reporting these numbers helps authorities trace and disconnect the culprits, which is more effective than simply blocking the number on your phone.
Your Quick Protection Checklist
Navigating the flood of calls can be stressful, but following a few simple rules can keep you safe. First, be immediately suspicious of any 10-digit number claiming to be from a bank or for a service update. Legitimate financial entities are mandated to use the '1601' series for these calls. Second, never share personal information like OTPs, PINs, or passwords over the phone, no matter how convincing the caller seems. Legitimate companies will not ask for this information. Third, use your phone’s built-in spam filtering features, which can automatically silence many unwanted calls. Finally, make it a habit to report suspicious numbers through the Chakshu portal or the TRAI DND app. Taking a minute to report a number contributes to a larger effort to clean up the network for everyone.
