For an interstate goods movement covered by the e-way bill rules, the person in charge of the vehicle should carry two things: the transaction document that fits the movement—an invoice, bill of supply or delivery challan—and either a copy of the e-way bill or its e-way bill number. The number may be available electronically; a paper printout is not automatically required. In an applicable import movement, the official e-way bill guidance also identifies a bill of entry.
The exact requirement depends on the goods, consignment value, reason for transport, route, exemptions and notifications in force on the journey date. Use this checklist with the live rules and portal status for the particular consignment.

The core documents to keep with the vehicle
Rule 138A(1) places the document duty on “the person in charge of a conveyance.” In practice, that is normally the driver or another person responsible for the vehicle and goods during transit. The rule states that this person shall carry:

Read the full provision on the CBIC Ewaybill Rules page. The official e-way bill FAQ also says that the person in charge can quote the e-way bill number to the proper tax officer for verification.

This does not mean that every interstate trip always needs an e-way bill. First establish whether Rule 138 applies, whether an exception or exemption covers the movement, and whether a notification changes the documents that must be carried.
Choose the underlying document that matches the movement
“Invoice, bill of supply or delivery challan” is not a menu from which the driver can choose freely. The correct paper or electronic record follows the transaction and the reason the goods are travelling.
Tax invoice
Use the tax invoice where the movement relates to a taxable supply for which an invoice is required. The invoice should describe the goods and the transaction consistently with the e-way bill data so that an officer can connect the load to the stated supplier, recipient and value.
Bill of supply
A bill of supply is used where GST rules require that document instead of a tax invoice, such as an eligible exempt or composition-related supply. It is expressly listed in Rule 138A as an alternative to an invoice when applicable.
Delivery challan
A delivery challan is appropriate only for the situations in which GST invoicing rules permit or require one. The CBIC invoice rules describe specified non-supply movements and circumstances in which an invoice could not be issued at the time of removal. Examples can include transport for purposes other than a completed sale, subject to the detailed conditions in those rules.
A delivery challan is therefore not a general substitute for an invoice on an ordinary taxable sale. The challan should state the movement purpose and contain the particulars required for that use case.

Bill of entry for an applicable import movement
The official e-way bill FAQ identifies a bill of entry for applicable import-related movements. That does not make a bill of entry necessary for every domestic interstate consignment. Use it when the import facts and customs documentation call for it, and keep the other required transport evidence as well.
When an e-way bill is generally required
The official portal FAQ describes the general threshold as a consignment value exceeding ₹50,000 under Section 68 and Rule 138. The description covers specified outward and inward supplies and movements for reasons other than supply, but it is subject to the rules’ exemptions and exceptions.
Treat ₹50,000 as the general rule, not a universal guarantee. Some specified handicraft and job-work movements can require an e-way bill below that amount. Goods-specific exemptions, notified movement categories and other exceptions can also change the result. Check the current Rule 138 position and the live portal before dispatch.
How to think about consignment value
The FAQ explains that the declared consignment value includes central tax, state or union-territory tax, integrated tax and cess charged. It also describes exclusions, including exempt supplies in certain mixed invoices and freight charged by the transporter. Apply the statutory definition to the actual consignment rather than estimating from the goods’ base price alone.
Movements other than a sale
An interstate journey can be for reasons other than supply—for example, a permitted transfer, return, testing or another documented business purpose. The e-way bill analysis still turns on Rule 138, the value and the applicable exception. Where the rules call for a delivery challan, do not replace it with a sales invoice merely because the truck is crossing a state border.
Can the driver carry only the e-way bill number?
Yes, where the e-way bill has been properly generated, the number may be carried or presented electronically. Rule 138A permits the copy or number, and the official FAQ says the person in charge may quote the number to the proper tax officer for verification. A printed copy is therefore not categorically required by the cited rule and FAQ.

Before departure, make sure the driver can reliably retrieve the number—such as through an authorised phone, dispatch message or other electronic record—and that the underlying invoice, bill of supply or delivery challan is also available. An e-way bill number without the transaction document does not satisfy the complete checklist.
RFID-linked alternative
Rule 138A also refers to mapping the e-way bill number to a Radio Frequency Identification Device embedded on the conveyance in the manner notified by the Commissioner. This is a notification-based method, not a reason to assume that any RFID device automatically replaces the other required records.
Invoice Reference Number as an alternative mechanism
Rule 138A allows a registered person, subject to the rule’s conditions, to use an Invoice Reference Number obtained from the common portal in lieu of the tax invoice. The rule states that the reference is valid for 30 days from upload. This is an alternative identification mechanism for the invoice; it does not authorise a vehicle to travel without the transport documentation otherwise required for the movement.

Validity: calculate it before the truck leaves
The official FAQ describes e-way bill validity for ordinary vehicles as one day for every 100 kilometres or part thereof. For over-dimensional cargo, it describes one day for every 20 kilometres or part thereof. The validity expires at midnight on the last validity day.
These are the FAQ’s distance-based calculations. Use the distance and vehicle category recorded for the actual consignment, then verify the live portal result and any extension available under current rules. A route change, a delay, trans-shipment or a vehicle change can affect the transport details and should be handled through the prescribed e-way bill process before the original validity expires.

What to check on the e-way bill
- Origin, destination and the states involved match the planned route.
- Part-B transport details, including the vehicle information required for the movement, are complete before the goods travel where the rules require them.
- The document number, date, goods description, quantity and declared value agree with the invoice, bill of supply or challan.
- The validity window covers the intended journey, including a realistic allowance for the route.
When a notification can change the documents
Rule 138A gives the Commissioner power, when circumstances warrant, to notify that specified documents are carried instead of the e-way bill. The rule names a tax invoice, bill of supply, bill of entry or delivery challan for goods transported for reasons other than supply.
This is a conditional, notification-based power. It should not be read as a blanket alternative that applies to every interstate journey. Check whether a notification actually covers the goods, movement and date in question.
A practical pre-departure procedure
- Identify the movement purpose. Decide whether the vehicle is carrying a taxable supply, an exempt or composition-related supply, an import-related consignment or goods moving for another documented reason.
- Select the correct underlying document. Prepare the invoice, bill of supply, delivery challan or applicable bill of entry under the relevant GST and customs rules.
- Establish e-way bill applicability. Check the general ₹50,000 threshold, then test the exceptions, exemptions, handicraft or job-work provisions and any goods- or movement-specific notification.
- Generate and complete the e-way bill when required. Enter the consignment and transport information accurately, including the vehicle details required for that stage of movement.
- Check the validity clock. Compare the portal’s validity with the route distance and whether the vehicle is regular or carrying over-dimensional cargo.
- Give the driver usable access. Provide the underlying document and the e-way bill copy or number in a form that can be shown or quoted to an officer. If using an electronic number, check that the driver can retrieve it without relying on an unavailable office system.
- Reconcile changes before movement continues. If the vehicle, transporter or route details change, update the e-way bill through the permitted workflow rather than carrying mismatched records.
What an inspection can verify
A proper officer can use the e-way bill number to verify the movement. The officer may compare the number and transport data with the goods and with the invoice, bill of supply, challan or applicable bill of entry. Consistent descriptions, quantities, values, consignor and consignee details reduce avoidable questions.
If the driver has only an invoice but no e-way bill number where an e-way bill is required, the document set is incomplete. Conversely, presenting an e-way bill number without the underlying transaction document leaves the officer unable to match the load to its legal basis.
Common mistakes and how to correct them
Assuming every interstate load needs an e-way bill
Interstate status alone does not settle the question. Apply Rule 138, the value rules and the specific exemptions. Keep evidence of the reason for any exemption so the driver can explain why the ordinary e-way bill requirement does not apply.

Treating ₹50,000 as an absolute floor
The official FAQ presents ₹50,000 as the general threshold, while also identifying specified cases below that value. Test the consignment against those provisions instead of stopping at the headline amount.

Using a challan for an ordinary sale
A challan has defined uses. For a normal taxable supply, use the required invoice; use a delivery challan when the invoice rules support that movement and document why the goods are travelling.
Printing an expired e-way bill
A copy that was valid at loading may not cover a delayed arrival. Check the expiry at midnight on the last validity day and follow the current extension or update process where available.
Ignoring the import context
An import movement can require a bill of entry identified in the official FAQ. Do not assume a domestic invoice alone describes the customs basis for imported goods.

Quick decision checklist for the driver or dispatcher
- Is the movement covered by an invoice, bill of supply, delivery challan or applicable bill of entry?
- Has the consignment been tested against the ₹50,000 general threshold and all relevant exceptions?
- Does the e-way bill, where required, contain complete and matching transport details?
- Can the person in charge show the e-way bill copy or quote its number electronically?
- Does the validity cover the route, vehicle type and expected travel time?
- Have any special notification, exemption, goods category or import fact been checked for this journey?
Bottom line for an interstate goods vehicle
Start with the applicable transaction document, then add e-way bill evidence when Rule 138 requires it: invoice, bill of supply or delivery challan as appropriate, plus the e-way bill copy or number. The number can be electronic or quoted to the officer, so a paper printout is not invariably necessary. Because thresholds, exemptions, notifications, consignment value and validity depend on the actual movement, verify the live rules and portal record before dispatch and keep the documents internally consistent.
