How to Generate E-Way Bills Through SMS

When Should You Use SMS for E-Way Bills?

SMS e-way bill generation is best used as a backup option when the portal, app, or software is not practical. It works well for single, urgent actions where you already have the required invoice and transport details ready.

• You do not have reliable internet access.
• You need to generate an e-way bill urgently.
• A vehicle breaks down, and vehicle details need to be updated.
• You need to urgently cancel or reject an e-way bill.
• A transporter needs to update transport details during movement.

Important 2026 Update Before Using SMS

As per the GSTN advisory dated 20 May 2026 and the later advisory dated 17 June 2026, new e-way bill changes have been introduced for Ship-to GSTIN and voluntary e-way bill closure. These changes are scheduled for production implementation from 1 August 2026.

Where Ship-to details are provided, and e-way bill generation is required, Ship-to GSTIN must be captured . If the Ship-to GSTIN is unavailable, URP may be entered where applicable. GSTN has also introduced a voluntary e-way bill closure facility, which allows eligible e-way bills to be closed after goods are delivered.

This is important for SMS users because the SMS format does not have separate fields for Ship-to GSTIN or e-way bill closure. For Bill-to/Ship-to transactions, e-invoice-linked e-way bill generation , or closure tracking, use the e-way bill portal, API, or GST software instead of SMS.

How to Register for the E-Way Bill SMS Facility

Before using SMS mode, you must register your mobile number on the e-way bill portal . A taxpayer can register up to two mobile numbers for this facility. 

Since SMS registration is done through the e-way bill portal, you may need to complete portal login requirements, such as two-factor authentication, before registering or managing the mobile number. Follow these steps to register for the e-way bill SMS facility:

1: Log in to the e-way bill portal.

2: Go to Registration.

1. Select For SMS.
2. Choose the user or sub-user.
3. Verify the mobile number through OTP.
4. Use the registered mobile number to send SMS commands.

Send e-way bill SMS commands to 7738299899 from the mobile number registered on the e-way bill portal. If the portal shows any updated or registration-specific instructions for your account, follow them.

SMS Formats for E-Way Bill Operations

Use one space between every field. Do not add commas, extra symbols, or unnecessary text. The formats below are based on the E-Way Bill System User Manual for SMS Operations.

Transaction Type Codes Used in SMS Formats

The transaction type tells the system why the goods are being moved. Some common codes are:

Reason Codes for Vehicle Update

Mode Codes for Vehicle or Transport Update

Note: For road movement, Veh_Tran_No typically refers to the vehicle number. For rail, air, or ship movement , it may refer to the transport document number.

Keep a small code sheet near the billing or dispatch desk. Most SMS errors occur due to incorrect transaction codes, incorrect date format, invalid GSTIN, incorrect HSN code, or incorrect vehicle number. 

Before Sending the SMS, Check These Details

Before sending the SMS, keep all the invoice and transport details ready. Check the GSTIN or URP, delivery PIN code, invoice number, invoice date, invoice value, HSN code, approximate distance, vehicle number or transport document number , and the correct transaction type code. 

This is important because SMS mode does not give you a proper review screen like the portal or software. If the details are incorrect, the system sends an error message to the registered mobile number. Correct the mistake and send the SMS again in the required format. Once the details are accepted, you will receive a reply SMS with the e-way bill number and confirmation.

Practical Dispatch Example

Suppose a transporter is moving goods by road and the original vehicle breaks down during transit . In that case, the dispatch or transport team should keep the e-way bill number, new vehicle number, reason code, and transport mode ready before sending the vehicle update SMS. For example, if the reason is a breakdown, the reason code will be BRK, and for road movement, the mode code will be 1.

After the SMS is accepted, save the confirmation SMS and update the dispatch record with the new vehicle number. This helps the billing, dispatch, and accounts teams match the e-way bill record with the actual goods movement later.

Limitations of E-Way Bill Generation Through SMS

SMS mode is useful for urgent, single e-way bill actions, but it is not built for every dispatch situation. Businesses should understand these limitations before relying on it.

Every Detail Must Be Typed Manually

In SMS mode, the GSTIN, invoice number, invoice date, value, HSN code, PIN code, distance, and vehicle details must be entered in the correct order.

In real dispatch workflows, the most sensitive fields are usually the invoice date, vehicle number, GSTIN or URP, and transaction type code because a small typing mistake in any of these can delay generation or require the message to be sent again.

Limited Visibility After Sending

SMS confirms the action with a reply message, but it does not provide the same level of detail, document preview, or workflow history as the portal or software. This can make it harder for teams to review and track dispatches.

Not Suitable for Complex Dispatch Scenarios

SMS works best for simple, one-off movements. For Bill-to/Ship-to cases, e-invoice-linked transactions, multiple invoices, or dispatches that need stronger validation, the portal, API, or GST software is a safer option.

Only Limited Updates Are Allowed

Once an e-way bill is generated, it cannot be fully edited. Only permitted updates, such as vehicle or transporter details, can be made where allowed.

Can E-Way Bills Be Automated Instead?

Yes. If your business regularly generates e-way bills, manual SMS or portal entry can become slow and error-prone.

With BUSY e-way bill software , businesses can generate e-way bills directly from invoices, reduce repeated manual entry, and keep e-way bill records linked with billing and GST reports.

This is useful for traders, manufacturers, distributors, transport-linked businesses , and companies handling frequent dispatches.

Conclusion

SMS-based e-way bill generation is a practical backup method. It is useful when internet access is not available, and you need to generate, cancel, reject, or update an e-way bill quickly.

For regular business use, the e-way bill portal, API, or accounting software is a better choice. These methods reduce manual entry, support better review, and are more suitable for bulk or complex transactions .
