Every JAV title carries a product code — a short alphanumeric string that functions as its universal identifier. Once you know how to read them, you can track releases, identify studios, and search across platforms far more reliably than trying to describe content in words.
The format is consistent: two to four uppercase letters followed by a three-digit number, separated by a hyphen. SSIS-456, IPX-789, CAWD-123 — that kind of thing. The letters identify the series or label; the number is the release sequence within that series.
The label portion isn't always the same as the studio name. A single studio often manages multiple labels, each with its own code prefix. S1 No.1 Style (one of the largest studios) runs several active prefixes. Over time, label codes change when studios launch new series, retire old ones, or rebrand entirely.
The number is just a counter — it tells you how many titles have come before under that prefix. A high number (like SSIS-600+) indicates an active, long-running series. A low number might mean a newer series or one that was short-lived.
On DUGA and MGS, the product code is the most reliable search term. Performer names transliterated into English sometimes return inconsistent results depending on how the platform romanizes them; codes don't have this problem. sexoc displays the code on each discovery card partly for this reason — it's a direct path to finding the same title on a licensed platform or searching for more from the same series.
