It’s used by the delivery people to contact me if they can’t find the delivery place or I’m not there. Also some of the local delivery companies will, for more expensive things, send the recipient an SMS with a code that you then give to the delivery person so that they know for sure they’re delivering to the right person (or somebody authorized by them).
It’s actually a pretty good way to solve a lot of problems with delivery, but it does mean I need to have a mobile phone number which ends up in the hands of at least two entities.





That would require for me to know which carrier would be doing the final leg of the delivery when the package is in my country, which often I don’t and it over time there’s even new carriers popping up.
A much simpler solution is to have a second mobile number which I give out for these things which is actually quite easy since I can just use a Pay As You Go SIM.
Might be worth changing the number AliExpress has on archive for me, though by now if the sold or leaked that info, it can’t be undone.
