The Instagram Notes Numbers Trend refers to a trend where Instagram users write a coded number combination beginning with "o," such as, o99, o45 or o22, each combination referring to the initial of their crush's name. The trend went viral in April 2023 on Instagram and on TikTok as users shared videos of their crush's codes and the decoder graph.


Sometime around April 2023, Instagram users began sharing coded numerical combinations using the Notes feature, each code referring to the initials of their crush. It is unclear where the Instagram Notes numbers trend started or where the decoder comes from. The earliest known video sharing the trend was posted by TikToker[1] @theyluv.qlf on April 7th, 2023, sharing the decoder, garnering over 829,000 views in three days (shown below).
