Under the current CGST Rule 138 calculation, an ordinary e-way bill is valid for one day for up to 200 km, plus one day for every additional 200 km or part of 200 km. Over Dimensional Cargo (ODC) and qualifying multimodal consignments with at least one leg by ship use one day for up to 20 km, plus one day for every additional 20 km or part. The clock starts when the first relevant Part-B transport detail is entered, and the portal says validity ends at midnight on the last day. If an exceptional delay prevents delivery, the current transporter can request an extension from eight hours before expiry until eight hours after it. Once an e-way bill has expired, goods should not continue moving on it.
Current e-way bill validity formula
Validity is determined mainly by the movement distance and the transport category recorded in the e-way bill. The 200-km standard comes from the amendment to Rule 138 made by Notification No. 94/2020-Central Tax, effective 1 January 2021. It replaced the older 100-km unit.

| Movement category | Validity calculation | Illustration |
|---|---|---|
| Ordinary transport | One day up to 200 km, then one additional day for every further 200 km or part of 200 km | 310 km requires two days under the distance formula |
| Over Dimensional Cargo (ODC) | One day up to 20 km, then one additional day for every further 20 km or part of 20 km | 21 km requires two days under the distance formula |
| Multimodal transport with at least one leg by ship | One day up to 20 km, then one additional day for every further 20 km or part of 20 km | The 20-km interval applies when the shipment meets the ship-leg condition |
The 310-km example means 200 km for the first day and a part of the next 200 km for the second day. The portal-generated “valid up to” value for the actual bill is the operative display, so check it rather than relying only on a manual calculation.

When the validity clock starts and ends
Validity does not automatically begin when Part A is created or when the document is generated. The E-Way Bill System FAQ identifies the first relevant Part-B transport entry as the start point:
- For road movement, it is the first vehicle number entered.
- For rail, air or ship movement, it is the first transport-document number entered.
- If different Part-B entries are added later, those later entries do not recalculate the original validity period.
The FAQ states that the period expires at midnight on the last validity day. Before dispatch, compare the displayed “valid up to” date and time with the planned route, loading schedule, trans-shipment points and likely disruptions. A distance estimate that looks adequate at generation can become inadequate after a breakdown, diversion or transfer delay.
Why some official pages show 100-km brackets
Readers can still encounter a CBIC-hosted HTML page headed “Ewaybill-Rules” containing a legacy table based on 100-km brackets and fixed day totals. That table conflicts with the later amended-rule PDF and current portal guidance. The amended Rule 138 text and the portal’s current calculation use 200-km increments for ordinary transport and 20-km increments for ODC or qualifying ship multimodal transport. Use the amended rule and the value displayed for your bill, not the old HTML table.
Can an e-way bill be extended?
Yes, but an extension is intended for an exceptional delay, not as a routine renewal. The portal guidance lists examples such as a natural calamity, a law-and-order problem, a trans-shipment delay or a conveyance accident. Your reason should describe what happened to this consignment and why the remaining journey cannot be completed before the displayed expiry.

The current transporter normally submits it. If no transporter has been assigned, the official API documentation allows the generator to update the validity.
Extension decision table
| Situation | What to do | Who normally acts |
|---|---|---|
| More than eight hours before expiry | Monitor the trip and prepare accurate current-location and delay information; the formal window has not opened yet. | Transporter, or generator if no transporter is assigned |
| Within eight hours before expiry | Submit an extension request if an exceptional circumstance exists. | Current transporter |
| Up to eight hours after expiry | Stop relying on the expired bill and submit the request immediately if the facts qualify and the portal accepts it. | Current transporter, or generator where no transporter is assigned |
| More than eight hours after expiry | Do not continue movement on the expired bill. The reviewed official materials do not establish a universal remedy; obtain case-specific GST advice. | Tax professional, responsible business officer and, where appropriate, the relevant tax authority |
How to request an extension in the portal
Use the e-way bill system’s validity-extension facility and make the request match the consignment’s real position. The exact screen labels can change, but the required information is defined by the portal and its API documentation.
- Check the bill and the clock. Open the e-way bill and note its displayed “valid up to” time. Confirm whether you are inside the eight-hours-before to eight-hours-after window.
- Confirm the physical location. Record the place and pincode where the goods are actually located when the request is filed. Do not use the original dispatch location if the vehicle has moved.
- Document the exceptional event. Select the applicable reason and add clear remarks—for example, a specific accident, breakdown, natural calamity, law-and-order disruption or trans-shipment delay. An unexplained request for extra time is not the same as an exceptional-circumstance request.
- Enter the remaining distance. Use the distance still required to reach the destination from the current location. The API validation says this value cannot exceed the distance declared when the e-way bill was generated.
- Update the transport details. For road movement, provide the vehicle number required by the Part-B validation. For rail, air or ship, provide the applicable transport-document number.
- Submit as the correct party. The current transporter submits the extension. If no transporter is assigned, the generator may submit it under the official system guidance.
- Save the result. Confirm that the portal accepts the request and record the updated validity details. A request that is merely attempted, rejected or left incomplete does not itself authorize continued movement.
Important extension validations
Current location and remaining distance must be credible
The extension data is a snapshot of the trip at the time of the request. A pincode, reason or remaining-distance figure that does not match the vehicle’s actual position can create a compliance problem and may cause validation failure.
Part A cannot be changed through the extension flow
The portal guidance says Part A cannot be changed while extending validity. Review the underlying invoice and consignee details before dispatch; the extension facility is for dealing with the delay and current transport details, not for rewriting the transaction.

There is also a 360-day restriction
The E-Way Bill System release notes and API documentation record a validation restricting extension activity to 360 days from the date of generation. That validation is listed as effective from 1 January 2025. It is separate from the eight-hour expiry window, so a request must satisfy both the timing window and the system’s age validation.
What to do when the e-way bill expires
The official FAQ answers the question directly: “If validity of the e-way bill expires, the goods are not supposed to be moved.” Treat that as the immediate operating rule.
If you are still within the eight-hour post-expiry window
Stop movement, secure the goods and submit an extension request promptly if the delay is an exceptional circumstance and the required information is available. Do not let the vehicle continue while waiting for a decision on an unsubmitted or rejected request.
If the eight-hour window has passed
Do not assume that creating a new e-way bill is automatically the correct cure. The official materials reviewed do not establish one universal post-window fix for every fact pattern. Keep the goods from moving on the expired document, preserve the invoice, original e-way bill, tracking and delay evidence, and obtain advice from a qualified GST professional or the relevant tax authority before taking the next compliance step.

If the portal rejects the extension
Record the rejection message and time, check each validation field, and do not repeatedly alter facts merely to force acceptance. If the rejection is caused by an incorrect location, distance, vehicle or transport-document entry, correct the factual error within the permitted window. If the window or 360-day restriction prevents submission, escalate for case-specific advice.

Expiry can expose the goods and conveyance to transit enforcement. Section 129 of the CGST Act provides a framework for detention or seizure and release proceedings for goods and conveyances in transit, including statutory penalty conditions. That does not mean every expired bill produces one identical automatic penalty. Outcomes depend on the facts, documents, movement status, tax position and action taken by the proper officer.
- Keep the invoice, e-way bill history, vehicle records, toll or GPS evidence and proof of the delay together.
- Show when the first Part-B entry was made and when the bill expired.
- Preserve accident reports, repair invoices, police or disaster records, carrier correspondence and trans-shipment documents where relevant.
- Do not backdate Part-B entries or invent a reason to fit the extension menu.
Practical planning checks before dispatch
- Classify the movement correctly as ordinary, ODC or qualifying ship multimodal.
- Calculate the distance using the current 200-km or 20-km interval, then verify the portal’s generated validity.
- Enter the first Part-B transport detail only when the consignment is ready to begin the relevant journey.
- Build realistic time for loading, border or checkpoint delays, trans-shipment and rest periods into the route plan.
- Give the transporter responsibility for monitoring the displayed expiry and the extension window.
- Keep contact details for the consignor, consignee, transporter and compliance officer available during transit.
Worked examples
Ordinary 310-km road trip
For an ordinary movement of 310 km, the distance formula gives two days: one day covers the first 200 km and a part of the next 200 km adds another day. The validity clock starts when the first vehicle number is entered in Part B, not merely when Part A is prepared. The displayed portal expiry remains the control point.
ODC movement of 61 km
An ODC movement uses 20-km intervals. Sixty-one kilometres comprises the first 20 km plus three further 20-km parts, so the distance formula produces four days. Confirm the classification and the portal-generated validity for the actual consignment.
Breakdown shortly before expiry
If a vehicle breaks down six hours before expiry, the current transporter is inside the request window. The transporter should record the actual place and pincode, state the breakdown in the reason and remarks, enter the remaining distance, supply the required vehicle detail and submit the extension. If the truck remains stopped after expiry, movement should not resume unless the system accepts an eligible extension or competent advice authorizes another compliant course.
Bottom line for carriers and businesses
Use the current 200-km rule for ordinary transport and the 20-km rule for ODC or qualifying ship multimodal transport. Start counting from the first Part-B transport entry and treat midnight on the final validity day as the expiry point shown by the portal. An exceptional delay can support an extension only in the eight-hour-before to eight-hour-after window, with accurate location, remaining distance, reason and transport details. If that window is missed, stop movement and obtain fact-specific GST guidance rather than assuming a new document or a fixed penalty outcome.
