Twins share the one thing nobody else has to split: the birthday itself. Which makes the twin birthday message its own genre — half celebration, half rivalry, all shared history from minute one.
Twenty-six options below: twin-to-twin, and for the friends and family of a matched set.

Happy birthday to us — but mostly to me. Kidding. (Mostly.) Love you, twin.
Send as a card →Happy OUR day, twin! Sharing a birthday with you is the only joint custody I've never contested.
Send as a card →Happy birthday to my womb-mate and lifelong plus-one. We literally started this together.
Send as a card →Twin, you're the only person who's been to every single one of my birthdays. Attendance award AND my whole heart. Happy birthday to us!

Send as a card →Happy birthday to the person who knows me without translation.

Send as a card →To us, twin. Always to us.
Send as a card →Same day, best day. Happy birthday, twin!
Send as a card →Two candles-worth of extra wishes today. Happy birthday!
Send as a card →Honor the shared day: 'happy OUR day' beats 'happy YOUR day' between twins — the joint ownership is the relationship.
The minutes-apart rivalry is mandatory material: whoever's older has never once let it go, and the card should keep the tradition alive.
For twin friends: greet both by name, never as a unit only. Twins spend their lives being addressed as a set; individual wishes inside the double celebration land best.
'Happy birthday to us' plus one only-us fact: 'you've attended literally every birthday I've ever had'. The shared-day framing is the whole charm.
Double everything and name them separately: 'Happy birthday Maya AND happy birthday Zoe — two cakes or it doesn't count.'
