However, Pelé has always maintained that those are mistakes, that he was actually named Edson and that he was born on 23 October 1940.

Shortly before I came along, there was another arrival in Três Corações: electricity. In order to celebrate this great improvement to our daily lives, Dondinho named me Edson, a tribute to Thomas Edison, the inventor of the lightbulb. In fact, on my birth certificate I am actually called Edison with an 'i', a mistake that persists to this day. I'm Edson with no 'i', but to my eternal annoyance quite often the 'i' appears on official or personal documents and time after time I have to explain why. As if that wasn't confusing enough, they got the date wrong on my birth certificate as well – it says 21 October. I'm not sure how this came about; probably because in Brazil we're not so fussy about accuracy. This is another mistake that carries on to this day. When I took out my first passport, the date was put in as 21 October and each time I have renewed it the date has stayed the same.
