I guess it depends on how the petitions work in countries? Where I'm from you never submit your national ID number (13 digit number given to each citizen once, never changes), but you do submit the "number" of your national ID (9 numbers and letters, changes when you move places or every 10 years, whichever comes first) when signing any petition.
