What do o26, o34, o45... mean on Instagram
Published onNovember 6, 2023

New trends can be very confusing until you’re in the know. The latest viral one popping up on Instagram is the appearance of a mystifying number-and-letter combination being added to a user’s profile via the Instagram Notes feature. It could be o26, o45, or some other secret clue. So what do o26, o34, o45, and the other various combinations mean on Instagram?
It would be tricky to work out on your own as there is seemingly no logic to the sequence. But don’t worry, we’ve got you covered.
QUICK ANSWER
The number and letter combinations are a code, with each one referring to a letter of the alphabet. o26 represents the letter "Y", o34 is the letter "H", and o45 represents "J". They're usually references to the first letter of the name of someone the poster has affection for. Check out the table below for the full code.
What do o26, o34, o45, and other combinations mean on Instagram?

The various letter and number combinations, such as o26, o34, and o45, are indeed secret codes, each indicating a letter of the alphabet. There isn’t much logic to how they map to the order of the alphabet, so you’ll just need to have the key to hand to work them out. We’ll get to that below.
Since only followers of the person posting the code can see the Instagram Note on the poster’s profile, the combination is usually used to refer to someone the poster is keen on. It’s often the first letter of someone they have a crush on, but could just be a signal to a best friend who’s been there for them.
For example, o34 represents the letter “H”. So if you’re getting all mooney-eyed about a Harry or a Helena and want to give them a clue as to your affection, you might post “o34” in your profile. o26 corresponds to “Y” if you want to shout out your bestie, Yvonne. Or you could use 045, which is “J”, to let Jessica know that she’s captured your heart.
The origin of the code isn’t completely clear, but the cryptic notes started appearing around April 2023. A helpful TikTok user later shared the key to help others get to the bottom of the mystery.
