Serial Number Example Generator
Generates a fictional serial-number-shaped example — "SN-" followed by a letter-and-digit block, a four-digit block and a closing letter pair — for product-catalogue mockups, warranty-system test data or documentation examples. Not a real, assigned serial number.
What this generator does
Produces a serial number in a mixed letter-and-digit format of the kind stamped on hardware. Intended for asset-register mockups, support-form testing and documentation screenshots.

How this generator works
A serial is assembled from the prefix SN-, two letters and a two-digit number, a four-digit number, and a closing pair of letters, each part drawn independently at random. The letters come from a 24-letter alphabet that leaves out I and O, the two most often misread as 1 and 0. There is no check character: nothing in the serial is computed from the rest of it, so it cannot be used to test check-digit validation.
Limitations and good to know
- Fictional examples for documentation and mock-ups. They identify no product, are registered with nobody, and will not validate against a warranty lookup.
- The shape imitates common conventions but matches no particular manufacturer's scheme, and it carries no check digit.
- Nothing checks for a collision with a serial that already exists, and no sequence is maintained between draws.
A formatting example only — not a real, assigned serial number for any product.
