Standardized IPO application form mandates a single ASBA/non ASBA booklet with uniform fields, serialisation and disclosure. SEBI mandates a single standardized Application Cum Bidding Form for ASBA and non ASBA applicants in A4 booklet format, with prescribed color coding by investor/repatriation status, mandatory eight digit serial application numbers with date/time stamping, and strict prohibition on altering spacing or data fields. The circular lists required data fields (PAN, single 16 digit depository account field, investor category/status, bid options with bid price/discount/net price, payment options including ASBA authorizations), signature and stamping rules, acknowledgement slips, and bid revision mechanics; it applies to RHPs/prospectuses filed on or after the specified effective date and is issued under SEBI's statutory powers.
