in aisle vs. on aisle

[Sweetpumpkin]

Hi,

I have a question on the prepositions before 'aisle'.

1)The detergents are on aisle Number 3.
2)The detergents are in aisle Number 3.

I think both of them are right. I mean, the general meanings of them are same. Maybe there are slight difference by the meaning of each prepositions, though. What do you think?

Thank you in advance,

Where I live, we would say "in aisle Number 3", but I think in some countries they use "on". The meaning is the same.
