· Published
GSTN Advisory 687, dated 4 November 2026, proposes that e-way bill numbers go from 12 to 14 digits from 1 January 2027. Consolidated e-way bill numbers would go from 10 to 11 digits on the same date. The change is marked proposed, and GSTN says the new formats will come to the e-way bill sandbox shortly. Before 1 January, check every place your business types, stores, prints or reads an e-way bill number. That means your ERP or billing software, Excel sheets, printed formats, transporter and customer portals, and gate entry.
Status: proposed by GSTN, not yet confirmed. We will update this page when GSTN confirms the change or announces a sandbox date.

What GSTN has proposed in Advisory 687
The official notice is GSTN Advisory 687, dated 4 November 2026. It covers the length of the number. Tax news sites taxguru.in, taxaj.com and calcguru.in also report it as proposed, with the sandbox coming "shortly".
Some pages describe the change as settled, or give a November sandbox date. As of 13 November 2026, it is marked proposed, with no sandbox date.
Number type | Today | From 1 Jan 2027 (proposed) |
|---|---|---|
E-way bill (EWB) number | 12 digits | 14 digits |
Consolidated e-way bill (CEWB) number | 10 digits | 11 digits |
A consolidated e-way bill is one document covering several e-way bills for goods moving in one vehicle. Its number changes to a different length, so check that path in your software separately.
Who it affects
The advisory names taxpayers, GST Suvidha Providers (GSPs), ERP vendors and API integrators. In a manufacturing business, that means two desks.
Billing and dispatch: the team members who generate e-way bills and print them on invoices and challans.
Stores and gate: the team members who receive supplier goods and key in or check the supplier's e-way bill number.
If either desk copies the number into a field built for 12 digits, the longer number can get cut off or rejected.
Owner checklist: 8 places to check before 1 January
Where | What to check | Who to ask | Done |
|---|---|---|---|
ERP or billing software | Takes 14 and 11 digits, stored as text | Software vendor | ☐ |
Excel registers | Column set to Text | Owner of the sheet | ☐ |
Printed formats | Boxes fit 14 digits | Vendor or form printer | ☐ |
Transporter and customer portals | Field accepts 14 digits | Transporter, customer | ☐ |
Accounting add-ons | Pull and print the full number | Add-on developer | ☐ |
GSP or API link | Both lengths, including consolidated | GSP or API provider | ☐ |
GRN and gate entry | Accepts 12 and 14 digits | Stores in-charge | ☐ |
Sandbox testing | Test bill run end to end | Vendor, GSP | ☐ |
1. ERP or billing software field length
The e-way bill field should accept, store, search and print 14 characters, and 11 for consolidated bills. It should hold the number as text, so no digits get rounded or dropped.
2. Excel templates and dispatch registers
In a General column, Excel can show a long number as 1.2E+13. Set e-way bill columns to Text before you paste. Check any macro that checks the number by its length.
3. Fixed-width printed formats
Invoices, delivery challans, lorry receipts and gate passes often have boxes sized for 12 digits. Widen them now, so the full number prints and stays readable.
4. Transporter and customer portals
If a transporter or customer asks you to paste the e-way bill number into their portal, check that field too. Ask whether it takes 14 digits from 1 January.
5. Accounting add-ons
Check your Tally add-ons (TDLs), or any add-on that pulls or prints e-way bill numbers. Ask the developer or partner who installed them.
6. GSP or API integration
If your software generates bills through a GSP or API, the link must handle both new lengths. Test the consolidated e-way bill path on its own.
7. Receiving side: GRN and gate entry
Expect to see both 12-digit and 14-digit supplier numbers for a while. Your GRN and gate entry screens should accept both.
8. Sandbox testing
GSTN says the new formats will come to the e-way bill sandbox shortly. Once they do, ask your vendor or GSP to run a test bill end to end.
Five tests for every system before 1 January
Accepts a 14-digit number on entry
Stores the number as text
Prints all 14 digits in full
Finds a bill by 14-digit search
Handles the 11-digit consolidated number
Where TranZact fits
Most of this checklist exists because one number gets retyped in many places. TranZact generates the e-way bill from the GST invoice, with e-invoice (IRN) in the same flow. This is available on all plans.
So the e-way bill number sits with its invoice and dispatch in one system, instead of being copied across sheets. For the full process, see our guide to e-way bill software for manufacturers. For IRN, read the e-invoice compliance guide.
On the 14-digit format itself, ask us the same vendor question you ask anyone else. Get the answer in writing.
Timeline to 1 January 2027
There are about seven weeks between today and the proposed start date. Use them in this order.
From advisory to proposed start date
4 Nov 2026: GSTN issues Advisory 687
Sandbox: new formats due shortly
Nov to Dec: get vendor answers, fix templates
Run test bills once sandbox opens
1 Jan 2027: proposed start date
As of 13 November 2026, GSTN has not given a sandbox date. Watch ewaybillgst.gov.in for GSTN's confirmation of the change.
What doesn't change
Advisory 687 is about the length of the number. It does not announce changes to who must generate an e-way bill, value thresholds or validity periods.
The sources we checked do not settle how bills generated before 1 January will be treated. Don't assume either way. Ask your CA and watch the portal.
Who to ask, and what to ask
Send each of these people one clear question this month. Ask for the answer in writing.
ERP or billing vendor: "Will your system take a 14-digit e-way bill and an 11-digit consolidated number?" Check it can store, print and search both. Then ask when you can test.
GSP or API provider: "Have you tested both new lengths in the sandbox, including consolidated bills?"
Accounting add-on developer: "Which of our add-ons read or print the e-way bill number, and will they show 14 digits?"
Your CA: "Does Advisory 687 change anything for us beyond the number length?"
Transporters: "Will your LR format and portal take a 14-digit number from 1 January?"
Top customers: "Will your vendor portal and GRN accept our 14-digit e-way bill numbers?"
Whoever owns your Excel sheets: "Which columns and macros hold e-way bill numbers, and are they set to Text?"
The proposed change is small, but the number shows up in many places. See the invoice to IRN to e-way bill flow run on your own dispatch.
