"MEIKO" comes directly from her voice provider's name, "Haigō Meiko."
MEIKO's codename was "HANAKO"; it likely came from "Yamada Hanako (山田花子)", a placeholder name for female characters, and the Japanese equivalent to "Jane Smith". "Megumi" was also a name considered during her development.
She is often misnamed Sakine Meiko by fans. The name originates from the eponymous derivative character.

The illustration was done by Shogo Washizu, often called わっしー(Wasshi), a former member of Crypton. Crypton placed this product on the market with box art that depicted a female character. This character had nothing to do with the singer's image, but her anime-based appearance appealed to a mainstream audience and the software sold well.
Wat described how different the intention of the CV series was to the concept of KAITO and MEIKO during the development of KAITO V3. Consequently Crypton took a different direction with their updates in comparison to the Appends of Hatsune Miku, Kagamine Rin/Len, and Megurine Luka.
MEIKO's VOCALOID1 boxart hid the front of her red sleeveless jacket, making it difficult to tell what the design consists of. Due to this, there are many different designs, even for official artwork. MEIKO has no official given age. In Maker Hikōshiki Hatsune Mix she is usually portrayed as a middle-aged woman, however KEI mentioned in a magazine interview that what he depicts in the comic is not official.
Spurned on by the items held by Hatsune Miku and KAITO, it became popular to feature MEIKO with One Cup Ozeki (sake).
