Use correct Punctuation on your mailings. Do the best you can. Many post-offices can verify your written certified and registered mailing- address is in their system while you are standing there.Your post office attendant in your country might not enter the ~tildes or hyphens into their system, which is ok. We have noticed some will cross out your Punctuation on your mailing to match their system, but please know your volition to mail with correct punctuation is still there .
