Used stamps exchanges.

Hello. I received an envelope from Diego of Milan, Italy but I’m missing the ID number for registration. Please provide. Thanks

"diego50used" is from 50stamps.club where you are both members.
You can contact this member there to ask about the letter.
I can't find there a letter in progress.

Hello. You curently don't have incoming letters from Italy. And I can't find a member with the name Diego. It's possible that this letter is not from this club.
