What is Transporter ID in E-Way Bill?

A Transporter ID (TRANSIN) is a 15-digit unique number assigned to transporters not registered under GST. It allows them to log in to the e-way bill portal and update Part-B vehicle numbers.

An e-way bill is the electronic permit document required for movement of goods above notified thresholds under India’s GST e-way bill system.

Definition

E-Way Bill: An e-way bill is the electronic transit document generated under Rule 138 of the CGST Rules for the physical movement of consignments valued over ₹50,000 across India.

Why it matters

Highway flying squads and RTO officers verify the 12-digit E-Way Bill Number (EBN) against the truck's vehicle number. Ops and billing must keep vehicle and invoice details aligned so e-way updates do not cause checkpoint penalties or delivery delays.

Difference Between E-Way Bill and E-Invoice

Transporters and shippers often ask about the difference between these two GST compliance mandates:

Feature	E-Way Bill	E-Invoice
Mandate	Rule 138 (Movement of Goods)	Rule 48(4) (Reporting B2B Invoices)
Threshold	Consignment value > ₹50,000	Business Turnover > ₹5 Crore
Generated By	Supplier, Buyer, or Transporter	Supplier only
Key Data	Part A (Invoice/Goods) + Part B (Vehicle No)	64-digit IRN + Signed QR Code
Validity	Distance-based (1 day per 200 km)	Permanent tax record

E-Way Bill Login & Transporter ID (TRANSIN)

Transporters log in at ewaybillgst.gov.in. Even if a road transporter is not registered for GST, they can register for an official 15-digit Transporter ID (TRANSIN) under 'Enrolment for Transporters'. This allows the carrier to update Part-B vehicle numbers whenever a truck breaks down or transfers cargo at a transhipment hub.

How to Extend E-Way Bill Validity

Under GST rules, standard cargo has a validity of 1 day per 200 km. If transit is delayed due to breakdown, accident, or roadblocks, validity can be extended online within 8 hours before or 8 hours after the expiry timestamp.
