Short verdict: is auto dialer legal in India today
The Auto Dialer publishes this summary because the answer changed recently. The governing rules are the Telecom Commercial Communications Customer Preference Regulations, 2018 (TCCCPR), issued by the Telecom Regulatory Authority of India. They do not prohibit auto dialers. They regulate commercial communication: calls whose primary purpose is to inform about, advertise or solicit business for goods or services. On 12 February 2025 TRAI's Second Amendment restricted senders from using normal 10-digit numbers for telemarketing and required senders to notify their operator, in writing and in advance, about the use of auto dialers or robo-calls. On 18 September 2026 the Third Amendment replaced that with a wider rule on Application-to-Person (A2P) calls and set a 7 day limit on calling someone on the strength of an enquiry.

Personal mobile numbers and is auto dialer legal in India
TRAI's own FAQ asks whether a mobile number may be used for telemarketing and answers no: a connection used to send promotional communication is liable to disconnection, and the subscriber may be blacklisted. That applies whether the number is dialled by hand or by an app. So a SIM based auto dialer does not turn a personal number into a telemarketing line. Two kinds of call fit the rules better:
- Service calls to your own customers. Information about a product or service they hold, such as delivery, warranty or renewal. TRAI's explanatory note says cross-sell and promotional offers do not count as service messages.
- Follow-up of a recorded enquiry. Within seven days of a written or digital enquiry that you can produce if asked.
A2P calls and phone apps: is auto dialer legal in India
The open question is whether a list dialled by an app on a handset counts as an A2P call. The Third Amendment does not name phone apps either way. Its definition is broad, covering calls initiated by an application without direct human dialling, and TRAI declined to exclude calls that connect to a live person. Until TRAI or your operator says otherwise, treat it as possible that app-dialled commercial calls need declaring, and ask your operator in writing. We do not describe The Auto Dialer as "TRAI compliant" or "approved", because no such certification exists for a dialer.
Compliance checklist for is auto dialer legal in India
- Sort your list by reason for calling: existing customer, recent enquiry, or neither. Do not auto dial the third group from a mobile number.
- Keep proof of each enquiry: the form entry, message or sheet row with its date. In The Auto Dialer every lead carries a source tag and a full history.
- Call enquiries promptly. The seven day window is short, and a follow-up reminder helps you stay inside it.
- Keep retries low. Complaints from five recipients in ten days can trigger action; see the auto redial settings.
- Honour "do not call me" and keep your own do not call list: use excluded numbers and the block list so that person is never dialled again.
- For promotional campaigns, use a registered telemarketing route on the 140 series. That is a different product; see auto dialer vs predictive dialer.

FAQ: is auto dialer legal in India
11 questions, answered
Is an automatic dialer illegal?
No law in India bans the automatic dialer as a tool. TRAI regulates the calls made with it: commercial calls must come from registered senders on designated number series, and software-initiated calls have to be declared to the telecom operator in advance.
Is cold calling illegal in India?
Promotional calls to people who have not asked for them are restricted. TRAI’s FAQ says a mobile number may not be used for telemarketing, and promotional calls are meant to go out on the 140 series from registered senders, respecting each person’s Do Not Disturb preference.
Is The Auto Dialer legal to use in India?
The Auto Dialer is a calling tool, and whether a call is allowed depends on who you call and why. It is intended for calling your own customers and people who recently enquired with your business. It is not intended for unsolicited promotional calling from a mobile number, which TRAI does not permit.
Which auto dialer use is safest under TRAI rules?
The lowest-risk use is service calls to existing customers and prompt follow-up of written or digital enquiries, with the enquiry kept on record. The Auto Dialer stores the lead source and call history for each lead, which helps you show why a call was made.
Does calling from my own SIM make promotional calls legal?
No. Using your own SIM does not change the category of the call. TRAI’s 2025 amendment restricts senders from using normal 10-digit numbers for telemarketing.
How long can I call someone after they enquire?
Under the Third Amendment notified on 18 September 2026, an enquiry creates a relationship for commercial communication for seven days, and the enquiry must be in writing or digital form and kept in a verifiable form. An application for a product or service gives three months.
What is a 140 series number?
Promotional calls by registered senders in India go out on the 140xx number range. This is general information, not legal advice. Any business wanting to make promotional calls is meant to place them on that range rather than on a normal 10-digit mobile number, whether the call is dialled by hand or by software.
What is the 1600 series used for?
This is general information, not legal advice. According to TRAI’s press release of 10 July 2026, banks, insurers and other BFSI-regulated entities, along with government bodies, use the 1600 series for their service and transaction calls. It is not a range for promotional calling.
What is an A2P call under the TRAI rules?
The Third Amendment of 18 September 2026 describes an Application-to-Person call as one started by an application or automated platform “without direct human dialling”, including autodialling. Senders must declare such calls and their number ranges to the operator in advance. Nothing in the text settles whether a list dialled by a phone app counts, so ask your operator in writing. This is general information, not legal advice.
What happens if people complain about my calls in India?
Under TRAI’s 2025 amendment, operators act against a sender when five or more unique recipients complain within ten days. The first step is barring outgoing services for fifteen days; repeat violations can bring disconnection for a year and blacklisting. This is general information, not legal advice.
Do TRAI rules apply to calls to existing customers?
Service calls about a product a customer already holds are treated differently from promotion, but TRAI’s explanatory note says cross-sell and promotional offers do not count as service messages. An application for a product supports commercial communication for three months. Keep the call about what the customer has. This is general information, not legal advice.
Calling your own enquiries and customers?
That is what this app is for. Ask for a trial and bring the list you are entitled to call.
