What do the numbers on her album covers mean?

The numbers are about her age. They are how old 아델 was when she wrote the songs, 19 - nineteen years old, 21 - twenty one years old.

The numbers on her albums represent how old she was when she made it. Like 아델 21 and 아델 19, that's how old she was when she made those albums. And I'm pretty sure there will be heaps 더 많이 to come. I'm her biggest fan.

Well, i though IT Was 의해 how many Songs she had, but i could Be her age, but its 50/50 chance

It can be number of song, 또는 it can be also number of her age but it really could be just a 랜덤 number which would keep use guessing it.

Do 당신 really have to ask this question? If u do, u're not a fan!

Early in the segment, Lowe quipped that 아델 was too young to have to lie about her age. Sessions for the album began when she was 25, though time has moved on. “I was 20 when 19 came out. I was 23 when 21 came out. I am 27. And so proud of being 27, thanks very much,” she explained. “But I quite liked it when I was 25.”

She then admitted she would do away with her system of naming albums after her age. “I think this will be my last age one. I’m sure I’m wrong with this but I feel there’s been a massive change in me in the last couple of years."
