What the number 143 really means when young people send it on WhatsApp

Ever scrolled through your WhatsApp chats and spotted “143” pop up without context? You’re not alone—it’s the latest mystery code making its rounds, and it speaks volumes in just three digits.

Decoding these secret numbers

I first noticed “143” when my niece messaged her best friend after a long day at school. No stickers, no words—just “143.” Intrigued, I asked what it meant, and she grinned: “It’s ‘I love you’ in code.” Sure enough, the digits break down neatly: 1 for “I,” 4 for “love,” and 3 for “you.” Simple, discreet and infinitely more playful than a heart emoji.

This trend, which first gained traction on TikTok, reflects a shift in how teenagers carve out moments of intimacy amid the daily barrage of messages. Rather than typing out “je t’aime” or “love you,” they weave these numbers into conversations, creating a private language that outsiders must decode.

But it doesn’t stop at 143. Young texters have extended the system with variations to express more nuanced feelings:

  • 1437: “I love you forever” (adding 7 for “forever”)
  • 687: A shorthand apology—“I’m sorry”
  • 1543: “I still love you,” ideal after a small tiff
  • 1122: A burst of encouragement, like saying, “You’ve got this”

Platforms like WhatsApp—used daily by over two billion people, according to Meta—offer the perfect canvas for this niche vocabulary. And it’s not just about secrecy: Pew Research Center finds that 67 per cent of teens prefer texting for emotional conversations, so blending numbers with words feels just right.

What makes these codes stick? They’re quick, they sidestep autocorrect mishaps, and they foster a sense of belonging. When you reply with “143,” you’re signalling membership in a club with its own inside jokes and shortcuts—a small rebellion against the generational gap.

Whether you’re a parent trying to keep up or simply curious about internet culture, next time you see “143” pop up, know that it’s more than digits—it’s a playful declaration of affection, wrapped in code. And if you spot something like “1122” or “1543,” you now hold the key to their hidden sentiments. Welcome to the secret language of WhatsApp’s youngest users.
