Not every business call is spam. A delivery update or a call about a quote you requested has a clear reason. An unwanted promotional call is different. The challenge is making that difference clear when businesses use large calling lists and automated systems.<\/p>\n\n\n\n
On 18 September 2026<\/strong>, TRAI updated its rules for commercial calls and messages in India. The changes cover how businesses must declare automated calls, how they can follow up on a customer inquiry, and when spam complaints can trigger action. They also give customers a way to appeal a complaint decision.<\/p>\n\n\n\n Here is what the TRAI spam rules for 2026<\/strong> say and what they mean for businesses that call customers. Source: TRAI\u2019s official announcement<\/a>.<\/p>\n\n\n\n TRAI uses the term Unsolicited Commercial Communication<\/strong>, or UCC<\/strong>, for unwanted business calls and messages covered by its rules. Whether a business call is allowed depends on why it is made and whether the business has a valid basis to contact that customer.<\/p>\n\n\n\n For example, calling someone who has just asked for a quote is different from calling a person who never asked to hear about your offer. TRAI\u2019s commercial communication regulations<\/a> set out how customer preferences, consent and complaints are handled.<\/p>\n\n\n\n Many businesses use software to start calls automatically. A system might dial numbers from a list, play a recorded message or use an artificial voice.<\/p>\n\n\n\n TRAI calls these application-to-person (A2P) calls<\/strong> when the software starts the call without a person dialling it directly. Under the 2026 amendment, a business using such calls must tell its telecom provider in advance<\/strong> that it uses A2P calling and provide details of the numbers it will call from. TRAI says A2P calls made without the required declaration will be treated as UCC.<\/p>\n\n\n\n What should a business do?<\/strong> If you use an auto dialer, robocalls or recorded voice calls, speak to your telecom provider about which calls need to be declared and how to submit the calling number details.<\/p>\n\n\n\n Imagine a customer submits a form asking about a service on Monday. Your team may need time to call them, answer questions and discuss the request.<\/p>\n\n\n\n TRAI\u2019s 2026 amendment says a business can send commercial communication based on a customer\u2019s inquiry for seven days from the date of that inquiry<\/strong>. But the inquiry must be made in writing or through a digital channel<\/strong>, and the business must keep a record it can verify later.<\/p>\n\n\n\n So, if your team follows up on leads, keep the form submission, message or other proof of what the customer asked and when they asked it. A name and phone number in a spreadsheet do not, by themselves, show that the customer made an inquiry.<\/p>\n\n\n\n Telecom providers use technology to spot numbers that may be sending spam. TRAI\u2019s new rule connects those signals with complaints from customers.<\/p>\n\n\n\n Earlier, the complaint threshold TRAI described was five or more complaints from different people within ten days<\/strong>. Now, action can start after three or more complaints from different people within ten days<\/strong>, if the calling number has also been flagged by the provider\u2019s AI system as suspected spam<\/strong>. Both conditions are needed for this new trigger.<\/p>\n\n\n\n TRAI has also said that if five or more numbers linked to one sender are flagged within ten days<\/strong>, telecom providers can investigate. Depending on what they find, steps may include checking the sender\u2019s identity again, stopping outgoing calls or disconnecting numbers in cases of repeated misuse.<\/p>\n\n\n\n For a calling team, the lesson is practical: look at customer complaints early. If many people report your calls as unwanted, check the campaign, the lead source and the reason for calling.<\/p>\n\n\n\n A business may have phone numbers collected years ago. It may also have records showing that some customers agreed to receive communications.<\/p>\n\n\n\n TRAI\u2019s amendment allows certain older, or legacy, consents<\/strong> to be recognised. But the consent must have been obtained in a way that can be verified<\/strong>, and it must be registered on the telecom provider\u2019s digital platform. Simply having an old customer list is not enough to establish consent under this provision.<\/p>\n\n\n\n If your business relies on old consent records, check whether you can show how and when each customer agreed<\/strong>.<\/p>\n\n\n\n What happens if someone reports a spam call but disagrees with how their complaint was resolved?<\/p>\n\n\n\n Under the 2026 change, the customer can appeal within 15 days<\/strong>. TRAI says appeal options include the TRAI DND app, a telecom provider\u2019s app or portal, and calling or texting 1909<\/strong>, along with other permitted complaint channels.<\/p>\n\n\n\n This is another reason for businesses to keep clear records of calls, inquiries and consent. Those records can help explain why a customer was contacted if a complaint is reviewed again.<\/p>\n\n\n\n Businesses often use registered SMS headers<\/strong>, which identify the sender, and templates<\/strong>, which set the approved message format. These can be misused if someone gets access to them.<\/p>\n\n\n\n Under the updated framework, a telecom provider that becomes aware of such misuse must suspend the affected header or template within six hours<\/strong>. TRAI also describes further steps for the sender and strong action where a telemarketer is responsible for the misuse.<\/p>\n\n\n\n If another company sends SMS on your behalf, make sure you know who can use your registered header and how misuse will be reported.<\/p>\n\n\n\n No. Individual customers can still block or filter calls on their own phones.<\/p>\n\n\n\n The 2026 rule addresses blanket spam tagging or blocking by call-management apps<\/strong> for designated business calling series such as 140<\/strong><\/a>, <\/strong>1600 <\/strong><\/a>and <\/strong>1601<\/strong><\/a>. TRAI wants legitimate calls from those series to avoid being automatically labelled as spam simply because they use that series. The customer\u2019s own choice to block a call remains intact.<\/p>\n\n\n\n The new rules are easier to understand when you apply them to your daily work:<\/p>\n\n\n\nWhat does TRAI mean by spam?<\/strong><\/h2>\n\n\n\n
