How to check your IPO allotment status
Allotment is decided and published by the registrar, not by any media outlet. For Tonbo Imaging the registrar is KFin Technologies; for Bonfiglioli Transmissions it is MUFG Intime. In each case the steps are the same:
- Go to the registrar's IPO allotment status page and select the IPO name from the dropdown.
- Search using your PAN, application number, or DP ID/client ID.
- Alternatively, check the allotment status on the BSE or NSE IPO allotment pages using the same details.
- If allotted, shares are credited to your demat account by October 22; refunds and UPI unblocks for non-allottees follow on the same day.
Remember: in an oversubscribed issue, retail allotment is decided by lottery — a valid application does not guarantee shares.
GMP snapshot ahead of allotment (October 20, unofficial)

FAQs
When will the Tonbo Imaging IPO allotment be finalised?
Allotment is expected on October 21, 2026, with refunds/demat credit on October 22 and listing on October 23. Dates are tentative until the registrar and exchanges confirm.
Which IPOs are being allotted on 21 October 2026?
Tonbo Imaging India, Shellz India (SME), Bonfiglioli Transmissions, Sahajanand Medical and Zetwerk — all five closed on October 19.
How do I check IPO allotment without an application number?
You can search on the registrar's allotment page or the BSE/NSE IPO allotment pages using your PAN or your DP ID + client ID.
Why is Tonbo's allotment so competitive?
The IPO was subscribed 135.90x overall with QIBs at 293.56x, so retail allotment will be heavily lottery-based and most applicants will receive refunds instead of shares.
Is GMP a reliable predictor of listing price?
No. Grey market premiums are unofficial, unregulated sentiment readings that can shift sharply before listing — treat them as context, not a forecast.
Conclusion
October 21 is the week's pivotal day for IPO investors: five allotments finalise, two listings debut, and India's biggest-ever IPO (Jio) opens for subscription the same morning. Check allotment status on the registrar or exchange portals once the basis is published, and watch the October 23 listing day for the five-way debut.
