DIKU

What does DIKU stand for?

Do I know you

If you’ve ever received a text message from a number you don’t recognize, you might have responded with DIKU. This acronym stands for ‘Do I Know You’. It’s a quick way to ask the sender to identify themselves before you carry on with the conversation.

You’ll commonly see DIKU used in situations where you’ve recently changed your phone number or you’re sending a message to someone for the first time. It’s a handy shortcut to clear up any confusion about who’s on the other end of the line.

For instance, if you’ve just texted your cousin’s boyfriend and he doesn’t have your number saved, he might reply with something like, “Sorry, but… DIKU?” It’s a polite way of saying, “I don’t recognize this number. Can you tell me who you are?”

Example for using ‘DIKU’ in a conversation

Hey! Just wanted to say hi and see how you’re doing. It’s been a while since we last talked.

Um, sorry, but do I know you? DIKU?

Oh, my bad! It’s [your name]. We met at [event/place].

Ah, got it! Sorry, I didn’t recognize the number. Nice to hear from you again!
