39 is also a shorthand for 'thank you' (san-kyuu) in Japanese, adding a layer of gratitude to Miku's name. So, Hatsune Miku fans also see it as a way to say 'thank you' to her!
Honestly, 39 is just a fun number that fans and creators have adopted to add a unique touch to Miku's identity. Nothing more, nothing less!
Miku's name can be read as 'mi-ku' (3 and 9) in Japanese, hence 39! It's a playful nod to her name.
