Argentinian passport number

[Jtee125]

Hi,

When entering information for a Argentinian passport to an airline, what is the correct passport number to provide?

There seem to be two options and I want to ensure I choose the correct one.

“Number”: 3 Latin characters followed by 6 numbers
“DNI”: 8 numbers

Is the “Number” including the 3 Latin characters what I should provide to the airline for checking into a flight?

Thanks!
