If you’ve been following my microSD Card Survey, you might have noticed that I publish manufacturer IDs for (almost) all of the cards that I’ve tested (save a few where they came DOA or where I tested them before I thought to dump the registers off the card).
I know that there are other resources out there that have compiled lists of SD card manufacturer IDs, but I thought I’d publish my own based on what I’ve seen during the course of my testing. So without further ado:
| Manufacturer ID | OEM ID(s) | Associated Brand Names |
|---|---|---|
00 | 0000 | Auotkn, “Lenovo” (knockoff), QEEDNS, QWQ, SanDian, Somnambulist, “Sony” (knockoff), “Xiaomi” (knockoff) — pretty much any fake flash vendor who wants to cover their tracks. |
00 | 3000 | Auotkn |
00 | 3432 (ASCII: 42) | Somnambulist, Gigastone, “Sony” (knockoff) |

1Multiple sources attribute this manufacturer ID to Phison. While I don’t disagree, I just haven’t come across any Phison-branded cards yet.
2The cards tested here dated to before Lexar’s sale to Longsys.
