Amazon Standard Identification Number; a unique product identifier used by Amazon for catalog management. Also refers to arcsine in mathematics.
Modern acronym from 'Amazon Standard Identification Number,' created for e-commerce product tracking. The mathematical 'asin' comes from 'arc sine,' where 'arc' indicates inverse function and 'sine' derives from Arabic 'jib' (fold/bay).
ASIN perfectly exemplifies how the digital economy creates its own language - what started as an internal cataloging system became part of seller vocabulary worldwide. It's remarkable how a simple product code can become as recognizable to online merchants as ISBN is to publishers.
