       Officials were stumped by his unusual name when he had to show it when he went for his vaccine appointment in the island of Sumatra, local reports say.

       Images of the boy’s paperwork and a name tag embroidered on his clothes show his name as ABCDEF GHIJK Zuzu.

       There are various reports as to how the family came to name their son as such, one saying it was due to the father's love of crosswords and another saying he wanted to become a writer.

       Zuzu, however, is derived from his parent’s names, Zuhro and Zulfahmi.

       But he he goes by the simplified nickname of Adef.

       Medics at the vaccination centre did not believe ABCDEF GHIJK Zuzu was the lad’s real name and he had to explain the reason and provide proof, it has been claimed.

       The 12-year-old boy has two older brothers with more normal names, Ammar and Attur, after their father lost the battle to call them NOPQ RSTUV and XYZ respectively.

       It comes as a Belgian family reportedly named their 11 children using a variation of the same four letters.

       Gwenny Blanckaert and Marino Vaneeno’s kids all share names that only have the letters A, E, L and X in them.

       The family of seven girls and four boys is also expecting baby number 12 - a boy - in April next year.

       Their eldest, 13, is called Alex and then there's Axel, 12, Xela, 11, Lexa, 10, Xael, 9, Xeal, 8, Exla , 5, Leax , 4, Xale , 2, Elax, 1, and six-month-old Alxe..

       In 2019, Gwenny and Marino said they planned to have more kids after giving birth to their ninth, who they named Xale, according to HLN.

       Explaining why they chose such a unique way of naming their brood, Gwenny said: "We named our oldest son after Marino's stepfather because we thought it was a beautiful name.

       "The name of our second son became Axel and after that we started puzzling."

       She later added: "We realized that they were the same letters, so we decided to continue like this."

       Speaking recently with Dutch media, the couple said they were "over the moon" about their new son.

       Gwynne said: "It will be a boy. That will bring the final score to 7-5. Seven girls and five boys."

       The couple have said they have no intentions of having any more kids after number 12.

       Gwenny said: "Right from the start we had set the bar at twelve. And we will stick to that.

       "The day that we sit around the table with twelve children, our family is complete."
