Recently someone advised me that while submitting letters / applications to Aayakar Seva Kendra (ASK) or tax counters, it has become a standard practice for leaving a clean top margin or blank space of about 2 to 2.5 inches on physical letters for ASK’s official endorsements, inward stickers, barcodes, or thermal acknowledgment stamps.
Is this correct? Are you all following this practice? Is it mandatory or pragmatic?
