• Best For: Real-time, legally binding institutional demand verification.

• Exchange Allotment Query Tool: Once the registrar completes the basis of allotment, BSE hosts a dedicated verification page where investors can check share allotment by selecting the issue name and entering their PAN and Application Number.
• Best For: SME IPO tracking and post-allotment verification.
