LPG DAC Code Rules 2026: Domestic LPG cylinders are an essential part of everyday cooking in millions of Indian households. Customers regularly book gas refills through mobile applications, online portals, customer service channels or their authorised LPG distributors. However, many consumers may encounter an unexpected problem when the delivery authentication code sent to their registered mobile number gets deleted or becomes unavailable.

The Delivery Authentication Code (DAC) is an important security feature used by LPG companies to verify cylinder deliveries. The code helps ensure that the booked refill reaches the intended customer and reduces the possibility of incorrect or unauthorised delivery confirmation.

But what happens if you accidentally delete the DAC message before your cylinder arrives? Will the delivery be cancelled, or can you still receive your LPG refill?

Fortunately, customers can contact their LPG distributor or use available official service channels to resolve the problem. The exact procedure may vary depending on the LPG provider and its delivery authentication system.

Here is everything consumers should know about the LPG DAC code, how to recover access to delivery verification and the precautions to follow when receiving a cylinder.

What Is an LPG Delivery Authentication Code?

The Delivery Authentication Code, commonly known as DAC, is a security code associated with an LPG refill delivery.

It works similarly to a one-time password and is used to confirm that a cylinder is being delivered to the correct customer.

When an eligible LPG refill booking is processed, the customer may receive a DAC through an SMS on the mobile number registered with the gas distributor.

During delivery, the authorised delivery representative may request this code to complete the verification process.

The authentication system is designed to improve transparency, reduce delivery-related disputes and prevent cylinders from being incorrectly marked as delivered.

Customers should remember that the DAC is intended for delivery verification and should not be shared with unknown callers or individuals claiming to offer unrelated services.

What Happens If Your LPG DAC Message Gets Deleted?

Many smartphone users regularly delete old messages to free up storage space or keep their inbox organised.

Some mobile devices also offer automatic OTP deletion features that remove authentication messages after a certain period.

As a result, an LPG customer may accidentally lose the DAC before the delivery representative arrives.

However, losing the SMS does not necessarily mean that the cylinder booking has been cancelled.

The refill order may remain active, and the customer can contact the authorised distributor to understand the available verification or code-retrieval procedure.

The method used to resend or regenerate the code depends on the LPG company's system.

1. Contact Your LPG Distributor Immediately

If you cannot find your DAC message, the first step is to contact your registered gas agency.

Explain that the delivery authentication message has been accidentally deleted or is no longer available.

The distributor may ask for information such as your registered mobile number, LPG consumer number or refill booking reference to identify the transaction.

After verifying the booking, the agency can guide you through the appropriate process for completing delivery authentication.

Customers should use the official contact details of their distributor rather than calling unfamiliar numbers received through unsolicited messages.

2. Inform the Delivery Representative About the Missing Code

If the LPG delivery person arrives before you have recovered the DAC, explain the situation clearly.

The authorised representative may be able to check the delivery status and advise you on the approved verification procedure.

Depending on the provider's system, a fresh code or another authorised verification process may be available.

However, customers should not assume that every delivery worker can independently generate a new DAC.

Any code regeneration or alternative authentication must follow the LPG company's official procedure.

Avoid sharing unrelated banking OTPs, UPI PINs or personal financial information with the delivery representative.

3. Ask Whether a Fresh DAC Can Be Sent

Some LPG delivery systems may provide an option to resend or regenerate the authentication code.

If this facility is available, the distributor or authorised delivery representative can explain how the request should be initiated.

A replacement code, where supported, may be sent to the customer's registered mobile number.

Consumers should verify that the message relates to their genuine LPG booking before sharing the delivery code with the authorised representative.

If a fresh DAC cannot be generated immediately, the distributor should be contacted for further assistance.

The availability of this facility can differ between LPG providers.

4. Check Your LPG Provider's Official Mobile Application

Customers can also check whether their LPG company's official application or customer portal provides booking and delivery-related information.

Major LPG providers in India include Indane, Bharatgas and HP Gas.

Their digital platforms offer various customer services, including refill booking and delivery status tracking.

Depending on the provider and the features currently available, customers may be able to view relevant delivery information or obtain instructions for resolving authentication problems.

Consumers should download applications only from trusted app stores and verify the publisher before entering account information.

Never install applications sent through unknown links claiming to recover an LPG DAC.

5. Make Sure Your Registered Mobile Number Is Active

An outdated or inactive mobile number can create difficulties when receiving LPG booking confirmations and authentication messages.

Customers should ensure that their registered number is operational and capable of receiving SMS notifications.

If the mobile number has changed, contact the LPG distributor to complete the prescribed update procedure.

Keeping contact information accurate can help prevent delays in booking confirmations, delivery notifications and other customer services.

It is also useful to check the phone's spam or archived message folders before assuming that the original DAC has been permanently deleted.

Important Safety Checks Before Accepting an LPG Cylinder

Recovering the delivery authentication code is only one part of receiving an LPG refill safely.

Consumers should also inspect the cylinder and verify important delivery details before accepting it.

Check the Cylinder Weight

Customers can request the delivery representative to weigh the cylinder using an appropriate weighing scale.

This helps verify that the cylinder meets the applicable weight requirements.

If there is a significant discrepancy, the issue should be reported to the distributor before accepting the refill.

Verify the Cylinder's Testing Due Date

LPG cylinders carry markings indicating their scheduled statutory testing period.

Consumers should check these markings and seek clarification if the cylinder appears overdue for testing.

The marking should not be confused with an expiry date for the LPG inside the cylinder.

Inspect the Safety Seal

Before accepting the refill, check whether the cylinder's safety seal and protective cap are intact.

A damaged or tampered seal should be brought to the delivery representative's attention.

Customers should avoid accepting a visibly damaged or suspicious cylinder without proper inspection.

Watch for Signs of Gas Leakage

Check for visible damage and any noticeable gas smell.

If leakage is suspected, do not operate electrical switches, ignite flames or attempt unsafe repairs.

Keep the area ventilated where safe to do so and contact the authorised distributor or LPG emergency helpline.

In India, the LPG emergency helpline is 1906.

Collect the Delivery Receipt

Always verify the amount charged and request the appropriate delivery receipt or invoice.

Check that the payment matches the applicable refill price and that any additional charges are legitimate.

Customers should report unexplained charges or delivery discrepancies through official complaint channels.

Can You Receive an LPG Cylinder Without the Original DAC?

Losing the original DAC does not automatically prevent a customer from receiving a booked LPG cylinder.

However, delivery completion depends on the authentication procedures followed by the concerned LPG provider.

Customers should contact their authorised distributor to request assistance with code retrieval, regeneration or any officially permitted alternative verification.

They should not pressure delivery personnel to bypass mandatory security procedures.

Following the approved process helps protect both customers and distributors from incorrect delivery records.

Final Takeaway

Accidentally deleting an LPG Delivery Authentication Code can be inconvenient, especially when a gas refill is urgently needed.

However, customers should not panic or immediately place another booking.

Contacting the registered distributor, checking official digital services and ensuring that the registered mobile number is active are sensible first steps.

Consumers should also verify cylinder weight, safety seals, testing markings and payment details before completing delivery.

By following the LPG provider's authorised authentication process, customers can resolve delivery-related problems while maintaining safety and security.
