Only got couple of pages left in my passport and thinking to do the replacement at $178 as it still has 6 years left on it.
Do they cut the bar code out of the old PP when re applying voiding it and do they change the passport number? Being a replacement I'm hoping not, so it can fill up.
Renewed mine at the post office and they cut about 20mm off the front cover and first page. Number stayed the same.
