E-Way Bill Validity

The e-way bill validity rule in one line

One day for the first 200 km, plus one more day for every additional 200 km or part of it. That is Rule 138(10) of the CGST Rules. A 200 km trip gets one day; 201 km gets two. Over-dimensional cargo — a single indivisible unit exceeding the dimensional limits of the Central Motor Vehicles Rules — and multimodal movements that include a leg by ship run on 20 km per day instead.

Validity by distance

The distance is the approximate road distance the consignment must travel. The portal estimates it from the pin codes of the origin and destination, and lets you declare a higher figure up to a limited margin above that estimate if the actual route is longer.

The midnight trap: how a "day" is counted

This is where most people lose time they thought they had. A day of e-way bill validity is not 24 hours from generation. Explanation 1 to Rule 138(10) says each day is the period expiring at midnight of the day immediately following the relevant date. The CBIC's own example makes the consequence concrete:

The practical rule that follows: on a trip whose distance sits close to a slab boundary, the hour at which Part-B goes in matters more than the extra kilometres. A driver who takes the vehicle number at 11 pm has bought a day that is nearly over.

When the clock actually starts

Validity is counted from the first entry in Part-B, not from when Part-A was saved. Part-A carries the invoice, consignor, consignee and goods details; Part-B carries the vehicle number for road movement or the transport document number for rail, air or ship. Until Part-B is filled, no validity is running — which means you can raise Part-A well ahead of dispatch without wasting a single hour.

Equally important: subsequent Part-B entries do not recalculate anything. If the goods are transhipped to a second vehicle mid-route, the transporter updates the vehicle number, but the validity period continues on the original clock. A change of vehicle is not a fresh start.

Extending an e-way bill

Extension exists, but the window is narrow: from eight hours before expiry to eight hours after it. Outside that window there is nothing to extend, and the movement needs a fresh e-way bill.

Extension is intended for exceptional situations rather than routine slippage — vehicle breakdown, an accident, a natural calamity, a law-and-order disruption, or a transhipment, warehouse or delivery delay. You state the reason, give the current place of the consignment and the vehicle details, and the remaining distance is used to work out the fresh validity on the same slab basis. Since 1 January 2025 the total extension is capped at 360 days from the original date of generation.

The 180-day rule on the document date

A companion restriction, live since 1 January 2025, blocks generation of an e-way bill against any document dated more than 180 days earlier. An old invoice cannot be pressed into service to cover a movement now. Between the 180-day entry limit and the 360-day extension cap, an e-way bill has a hard outer life in the system.

When you need an e-way bill at all

An e-way bill is required for the movement of goods where the consignment value exceeds ₹50,000, taken from a single invoice, bill of supply or delivery challan — whether the movement is for a supply, a return, or a reason other than supply such as a stock transfer or job work. It is generated by the registered supplier or recipient, and where neither has done it, by the transporter.

Two qualifications are worth knowing. Several states set a higher threshold for purely intra-state movement, so check your own state's notification before assuming ₹50,000 applies inside the state. And a list of goods is exempt outright — among them LPG for domestic supply, kerosene under PDS, currency, used personal effects, and unworked precious stones — along with movement by non-motorised conveyance and short customs-area movements.

If it expires while the goods are in transit

Moving on a lapsed e-way bill is treated as movement without a valid document, and the consignment can be detained under Section 129. Where the owner comes forward, release of taxable goods costs a penalty of 200 percent of the tax payable on them; where the owner does not come forward, it is the higher of 50 percent of the value of the goods or 200 percent of the tax. Officers do accept genuine transit delays as a reason for extension — but only if you extended inside the eight-hour window. After that the argument gets much more expensive.

The defensive habit is unglamorous and effective: when Part-B goes in, note the expiry, and if the trip is running late, extend before the deadline rather than after the checkpoint.
