What Is the 7-Day Customer Inquiry Rule for Commercial Communication?

Imagine that a customer fills out a form and asks for a quotation. Can the business call the customer back, or will the call be treated as an unwanted commercial call?

TRAI’s 2026 amendment gives businesses limited permission in this situation. If a customer asks about a product or service, the business can contact that person for the next seven days. However, this does not mean businesses can call every old lead or contact on a purchased list.

The customer must have made the inquiry in writing or through a digital channel. The business must also keep proof of that inquiry. Before making the call, it should check whether the call includes a promotion, respect the customer’s opt-out choice, and follow the required A2P, DLT, and numbering rules.

What does the 7-day customer inquiry rule say?

The Telecom Regulatory Authority of India, or TRAI, introduced this provision through the Telecom Commercial Communications Customer Preference (Third Amendment) Regulations, 2026.

The rule allows commercial communication to be sent when a customer has made an inquiry to the sender about a good, product, or service. This communication can be based on that inquiry for a maximum of seven days from the date of the inquiry.

This change is part of the definition of “Relationship” under the Telecom Commercial Communications Customer Preference Regulations. It is not a separate licence for businesses to make unlimited sales calls.

The inquiry must be made in writing or through digital means and retained in a verifiable form. The official PIB explanation of the amendment says that the provision is intended mainly to support e-commerce and e-service platforms.

The rule in simple terms

Requirement	What it means
Customer initiated	The customer must have contacted or submitted an inquiry to the sender
Relevant subject	The inquiry must relate to a good, product, or service
Written or digital	The inquiry should exist in a form that can be checked later
Verifiable record	The sender must be able to prove what the customer asked and when
Time limit	The inquiry can support communication for a maximum of seven days
Earlier opt out	A clear request not to be contacted should be respected earlier

Why did TRAI introduce this rule?

Businesses need to answer genuine requests for quotations, demos, appointments, and service details. At the same time, a vague CRM entry or an old database should not become a reason for repeated promotional calls.

The amendment balances these needs by recognising recent customer interest for a short period while requiring written or digital proof. The focus is on the quality and age of the inquiry, not just the fact that a phone number exists in a CRM.

What can count as a customer inquiry?

TRAI has not published an exhaustive list of every possible inquiry format. Businesses should therefore use a conservative approach and retain the original customer action.

Examples that may support an inquiry record include:

1. A website form asking for a price, quotation, demo, callback, or appointment
2. An email, chat, app message, or social message asking about a product or service
3. An online marketplace or e-service request that asks the provider to make contact
4. A digital request about availability, delivery, pricing, features, or service coverage

The strongest record contains the customer’s original words, the date and time, the phone number or customer identifier, the channel used, and the product or service discussed.

What should not be treated as a safe inquiry?

Some information may indicate interest, but it does not automatically prove a qualifying inquiry.

Businesses should be careful with:

1. A purchased or rented lead database
2. A phone number collected without a related product or service request
3. A website visit or advertisement click with no recorded inquiry
4. An employee’s CRM note saying “interested”
5. A missed call or oral conversation with no written or digital record
6. A third-party lead or old inquiry that cannot be verified or is more than seven days old

A CRM note can be useful for internal work, but it should not replace the original form entry, email, chat, or other evidence of the customer’s action.

How should businesses manage the seven-day period?

The seven-day period begins with the customer’s inquiry. It does not begin when a sales employee imports the lead, opens the CRM record, or makes the first call.

It is also not a rolling period. A sender cannot make a new seven-day period start after every follow-up call. If a customer sends a fresh, genuine inquiry later, that new event should be recorded separately.

Businesses should follow this workflow:

1. Capture the original inquiry and its timestamp.
2. Store the customer’s phone number and the subject of the inquiry.
3. Link every follow-up call or message to that inquiry.
4. Set an automatic expiry before the seven-day window ends.
5. Stop communication earlier if the customer opts out or ends the relationship.
6. Use another valid basis after the inquiry window has expired.

Since the regulation does not provide a detailed hour-by-hour counting formula, businesses should avoid relying on the final edge of the window without confirming the implementation process with their telecom provider.

Inquiry, application, consent, and service communication are different

The 7-day customer inquiry rule is easy to confuse with other communication rules.

Basis for communication	Main time or condition
Customer inquiry	Maximum seven days from the inquiry
Customer application	Separate relationship basis covering an application made within the preceding three months
Existing business relationship	Depends on the applicable relationship and inferred consent provisions
Explicit consent for an ongoing service transaction	Valid for seven days or until revoked, with renewal at the customer’s request
UCC complaint	A separate seven-day complaint window may apply

A customer who only asks for information has not necessarily made an application. A business should not label a basic inquiry as an application just to claim a longer period.

Similarly, an inquiry is not the same as explicit consent for every type of marketing. The purpose, content, channel, and applicable telecom process still matter.

Does the rule allow promotional calls?

The official wording refers to commercial communication, not only promotional calls. Therefore, an inquiry may support a commercial follow-up about the product or service the customer asked about.

However, businesses should not use the inquiry rule to hide promotional content inside a service call.

For example, a call asking whether the customer needs the quotation they requested is different from a call that uses the inquiry as an opportunity to sell unrelated products. Cross-selling, upselling, discounts, and promotional offers may still be treated as promotional communication.

TRAI’s 2025 amendment document also explains that promotional content should not be mixed into service communication.

The safest approach is to classify the communication based on what it actually contains, not on the label used by the sender.

How does the rule relate to A2P and robocalls?

The inquiry rule does not remove the separate requirements for automated calls.

Under the 2026 amendment, an Application-to-Person, or A2P, call is a voice call initiated by an application, software system, or automated platform without direct human dialling. The definition includes autodialling, robocalls, and prerecorded or artificial voice technologies.

Businesses using A2P calls must declare this use to their originating telecom provider in advance. The declaration includes the Calling Line Identification, or CLI, ranges that will be used. An A2P call made without the required declaration can be treated as unsolicited commercial communication.

The official PIB release also mentions a termination charge of up to ₹0.05 per minute for applicable A2P calls. This is not the same as a charge of ₹0.05 per call.

In short, a genuine inquiry may support a limited follow-up, but it does not correct an undeclared automated calling setup.

What records should a business retain?

TRAI requires the inquiry to be maintained in a verifiable form, but the PIB summary does not prescribe one universal CRM format or a specific inquiry record template.

A practical record should include:

1. Customer name or identifier, where available
2. Phone number used for communication
3. Original inquiry text, form entry, email, or chat
4. Date, time, and time zone
5. Product or service discussed
6. Source channel and campaign reference
7. Opt out status and follow-up history
8. Human or automated calling classification

Access should be limited to authorised employees, and the record should be exportable if a telecom provider, auditor, or regulator asks how a communication was justified.

What does this mean for a calling team?

A calling team should not depend on memory or scattered phone histories. Its workflow should show:

1. Which customer made the inquiry
2. What the customer asked for
3. Who owns the follow-up
4. When the seven-day window expires
5. Whether the next call is manual or automated, and whether the customer has opted out

A cloud telephony platform such as CallerDesk can connect call activity with lead ownership, follow-up work, call history, and customer records. It does not replace the sender’s responsibility to follow TRAI and telecom provider requirements.

Conclusion

The 7-day customer inquiry rule gives businesses a narrow way to respond when a customer has shown genuine interest. It does not turn every lead into permission for repeated sales calls. The inquiry must be written or digital, verifiable, recent, and connected to the product or service discussed. Teams should also check whether the message is promotional, whether the call is A2P, whether the customer has opted out, and whether the relevant telecom process is in place. A clear workflow makes this easier: capture the inquiry, assign the follow-up, record the call, and stop outreach when the window ends.
