How extraction works
An ASIN is 10 characters from 0-9 and A-Z (case-sensitive, uppercase only). Tokens found right after /dp/, /gp/product/ or /gp/aw/d/ in a URL, or starting with B0 (the current prefix series), are treated as confirmed. Pure 10-digit numbers are listed separately as ISBN-10 candidates, and 13-digit numbers as EAN-13, so barcodes never masquerade as ASINs.
All extraction happens in your browser with local JavaScript — nothing you paste is uploaded.
