The invoice carries the wrong GSTIN. Is the credit lost?
A clerical error by a vendor becomes a demand in one state and an unusable credit in another. It is fixable if it is caught in time.
Credit is available to the registered person to whom the supply was made, and an invoice bearing the GSTIN of a different registration of the same entity does not make the recipient ineligible in substance. The practical difficulty is that the invoice appears in the GSTR-2B of the wrong registration. The cure is an amendment by the supplier in a subsequent GSTR-1 within the permitted period, or a credit note and a fresh invoice. Once the amendment window has closed, the position becomes evidentiary.
Why this matters more than it should
Section 16(2)(aa) requires that the details of the invoice have been furnished by the supplier and communicated to the recipient. Where the invoice is reported against another GSTIN, that condition is not satisfied for the registration that received the supply.
The credit is therefore challenged in the state where it was taken, on the ground that it does not appear in that registration's GSTR-2B, and it cannot be taken in the state where it appears, because that registration did not receive the supply.
Two demands from one typing error. This is why the reconciliation must be run monthly rather than annually.
The cure, in order of preference
Amendment by the supplier in a subsequent GSTR-1, which moves the invoice to the correct GSTIN and repairs the 2B. This is the clean answer and it is available only within the amendment window for that financial year.
Credit note against the wrong invoice and a fresh invoice to the correct registration, where an amendment is not possible. The commercial consequence is a reversal and a fresh availment, with the Section 16(4) date to watch.
Where neither is possible, the claim is made on the substance — the purchase order, the delivery to the correct premises, the payment by the correct entity, and the supplier's confirmation. Diya Agencies and the line that credit cannot be denied solely on a 2A or 2B absence support this, but it is a harder road.
Related errors and how they are treated
Wrong address with the correct GSTIN: a minor defect. Rule 46 prescribes the particulars and the courts and circulars have treated a wrong or incomplete address with the correct GSTIN as a curable irregularity.
Missing GSTIN of the recipient altogether: more serious, because the invoice is then not a tax invoice for the recipient. Obtain a revised invoice.
Wrong place of supply, which affects the head of tax rather than the credit, and is dealt with by the Section 77 refund route.
Wrong rate charged: credit is confined to the tax properly payable, and the excess must be recovered from the supplier through a credit note.
What to do on Monday
Run the GSTR-2B reconciliation monthly and route GSTIN errors to the vendor the same month, while amendment is still possible.
Include the correct GSTIN and place of supply in the purchase order and on the delivery instruction, not only in the vendor master.
For e-invoices, check the reference number against the correct GSTIN on receipt, because the cancellation window is short.
Keep the purchase order, delivery record and payment trail for any credit availed without a 2B match.

Write to the GST practiceQuestions we are asked on this
Can the branch that received the supply take credit if the invoice shows the head office GSTIN?
Not from the 2B, which is where the dispute starts. Get the invoice amended; failing that, be ready to prove the supply and the recipient identity on documents.
Is a wrong address on the invoice fatal?
No, where the GSTIN is correct. It is a curable defect and should be corrected prospectively.
How long does the supplier have to amend?
Amendment is possible in a subsequent GSTR-1 up to the time limit for that financial year. After that the credit note route or the evidentiary route is all that remains.
Does an e-invoice with the wrong GSTIN cause a bigger problem?
It is harder to amend because the invoice reference number is generated against the reported GSTIN. Cancellation within the permitted window, where available, is the cleanest fix.
Should we take the credit and disclose, or not take it at all?
Availing credit that does not appear in your 2B invites a demand. Where the amount is material, avail with a contemporaneous note and pursue the amendment in parallel.
