Seeing this error? Wrong digit count or an unrecognised HSN code triggers this error. Below are the common causes and the fixes that resolve it for most users.
Why this happens
- The HSN code has the wrong number of digits for your turnover slab.
- A non-existent or mistyped HSN was entered.
- Services (SAC) were entered where goods HSN is expected.
How to fix it
1
Use the right digit length
Use 4, 6 or 8 digits as applicable to your turnover and product.
2
Verify the HSN
Cross-check the HSN against the official HSN directory before entering.
3
Goods vs services
E-Way Bills are for goods — use a valid goods HSN, not an SAC code.
Important
If the problem is on the portal side (maintenance or server load), no browser fix will help — confirm with a second network first.
