The figure reportedly comes from the final three digits of Rocafonda’s postal code, 08304. Yamal forms the numbers three, zero and four with his hands after scoring, turning a local reference into a recognisable football signature.
The report says Yamal spent his childhood in Rocafonda after moving there with his family, despite being born in Esplugues de Llobregat. That distinction matters: the celebration represents the area where his identity was shaped, rather than simply the location on his birth certificate.
The celebration has reportedly appeared after important goals for Barcelona and Spain, giving it a stage far beyond Mataró. Its repetition has helped supporters associate the number directly with Yamal.
The report also says 304 appears on personalised boots, alongside his initials and flags linked to his family heritage. That takes the gesture beyond a spontaneous celebration and into deliberate branding.
Rocafonda’s multicultural character also forms part of the story. Yamal’s father is Moroccan and his mother is from Equatorial Guinea, while the player has continued to express pride in those roots when representing club and country.
Football celebrations often become shorthand for a player’s identity. Yamal’s is distinctive because it points away from celebrity and back towards his beginnings. Children and supporters in Rocafonda have reportedly copied the gesture, giving the number a communal meaning.
The next storyline will be whether 304 becomes a lasting part of Yamal’s career as he takes on bigger matches, greater expectations and an even larger global audience.
