E-way bill rules: when you need one, Part A and B, 200 km validity
When an e-way bill is required under rule 138, the ₹50,000 consignment line, what goes in Part A and Part B, the 200 km per day validity from notification 94/2020, GSTR-3B blocking, and how to confirm on the official portal.
In this guide
An e-way bill is required before goods move when a registered person causes movement of a consignment worth more than ₹50,000. Rule 138 needs Part A of Form GST EWB-01 on the portal; Part B carries the vehicle. Validity is one day per 200 km from 1 January 2021. Generation is blocked if GSTR-3B is unfiled for two consecutive months. Confirm on the official e-way bill portal before the truck leaves.
When you need an e-way bill
Rule 138 is the working text. A registered person who causes movement of goods of consignment value exceeding ₹50,000 has to furnish Part A of Form GST EWB-01 on the common portal before the movement starts. That covers a supply, a movement that is not a supply, and an inward supply from an unregistered person.
The official e-way bill site repeats the same ₹50,000 line. Section 68 is the Act hook: the person in charge of the conveyance has to carry the prescribed documents. The e-way bill is that document for a motorised movement of goods.
Non-motorised conveyance is out. So are the goods listed in the annexure to rule 138. Intra-State thresholds can be higher because a State notification said so. If the truck never crosses a State border, read that State notification instead of assuming ₹50,000.
Part A and Part B
| Part | What it carries |
|---|---|
| Part A | Invoice or delivery-challan particulars, GSTINs, pin codes, HSN, value. This is what creates the e-way bill number. |
| Part B | Vehicle number, or the transporter ID if you are handing the goods to a transporter who will fill the vehicle later. |
Part A without Part B is not a bill you can move goods on, except in the narrow cases the rule allows (for example, movement up to 50 km within a State for transport to or from the transporter). If the vehicle changes, update Part B. Do not generate a second Part A for the same invoice unless you have cancelled the first bill.
If the invoice was an e-invoice, pull it by IRN. Re-typing the same invoice is how HSN and value drift between the two systems.
Validity is 200 km per day
The official portal still flags notification 94/2020 on its home page: from 1 January 2021, validity is 200 km per day, not 100. One day means the period ending at midnight on the day after the bill was generated, and then one more day for each further 200 km.
Over-dimensional cargo uses a shorter distance per day. If that is your load, read the current rule 138(10) table, not the standard 200 km line.
Expiry is not a suggestion. An expired bill does not cover the rest of the journey. Extend it only where the portal still allows an extension, and only for the reason the form offers.
Blocking for GSTR-3B, and 2FA
Generation is blocked, as consignor or consignee, when GSTR-3B has not been filed for the last two consecutive tax periods. The official banner says this applies regardless of aggregate turnover. Filing GSTR-1 does not lift the block.
If the return is filed and the e-way bill site still shows blocked, use Search → Update Block Status on ewaybillgst.gov.in. That refresh is the documented fix. Opening a ticket before you click it wastes an afternoon.
Two-factor authentication is mandatory for every taxpayer and transporter from 1 April 2025. That is a portal notice, not a rumour. A dispatcher who only has the password will not generate a bill after that date.
How to confirm on official pages
- Read the current text of rule 138 on the official e-way bill site, then section 68.
- Check live operational notices on docs.ewaybillgst.gov.in, including validity, blocking and 2FA.
- Generate only on ewaybillgst.gov.in. A State VAT lookalike is not the GST e-way bill.
If the movement is intra-State, also open that State's notification on the threshold. The Central ₹50,000 line is not always the intra-State line.
Where Complied AI fits
Rule 138 changes arrive as Central Tax notifications and as portal advisories. CBIC / GST updates on Complied AI keep the notification next to the rule so you are not running a 100 km validity table in 2026.
Practical checks
Common questions
What is the e-way bill limit under GST?
Rule 138 starts at consignment value exceeding ₹50,000. That is the figure the official e-way bill portal repeats. Some States set a higher intra-State line by notification. Interstate movement follows the Central rule unless a specific exemption applies. Read the State notification if the movement is only inside one State.
How long is an e-way bill valid?
From 1 January 2021, notification 94/2020 changed validity from 100 km per day to 200 km per day. The official e-way bill portal states that change on its home page. Over-dimensional cargo has its own shorter distance per day. Do not copy a 100 km table from an old printout.
Why is e-way bill generation blocked on my GSTIN?
The official portal blocks generation, as consignor or consignee, when GSTR-3B has not been filed for the last two consecutive months, regardless of AATO. If you have filed and the portal still shows blocked, use Search → Update Block Status on ewaybillgst.gov.in.
Is 2FA mandatory on the e-way bill system?
Yes, for all taxpayers and transporters from 1 April 2025. That is a portal update posted on the official e-way bill documentation site. Keep the registered mobile or the authenticator ready before a late dispatch.
