the same on me, DV, all prior passports been German Passports, heck, obtaining that one anyways meant that there's no need for any other, easy to travel the whole world, doesn't matter you visit Canucks or americans or arabs or chines or africa or the caribbean, lol.
the actual one, which i received in 2012 for 10 years, is my first with that "chip" on it, maybe they changed passport numbers due that. on the other hand, it is the first passports which i got issued/renewed by the Embassy here, so the change of location/issuing office may also be in charge for the change of the passport number.
if you open bank accounts with passports instead of a cedula, then you have to write solicitudes for the changes of the documentations for each bank etc etc, they are strict nutheads with those simple little things here, i could write a book about such stuff. since i have everything registered solely with my cedula, all runs smooth and fine, the passport stays in the security boxe and comes out for travels out of the country only, hence no danger to get it stolen out of the house on a attack or such.
