Do i need to change my passport address when moving home?

I am in the United States and called about this same issue. They told me that I need to write a letter to the National Passport Center and that my address would be updated in their system. My passport does not have an address on it either.

There is no address in your passport and so there is no need to tell the passport. As a rule, if anything that you can read and see on your passport changes, you need to change the passport e.g. name changes.

No you don't need to change your passport, but you will need to change your driving licence and log book... for example if your car gets stolen, it would mean that the police would have trouble tracing you..

I had to look at my passport. I could have sworn it had my address. It doesn't. lol Unless it has expired, you should be fine with it the way it is. Granted, mine says I live in Pennsylvania. I'm sure if I move to, say, Virginia again (God forbid), I would have to update it, but wouldn't have to get a new one until this one is no longer valid. I've got 9 years left on this one.

no - passport covers the person not address. They only need an address when you are renewing/applying for a passport

What passport have you got? Doesn't have your address on the passport.
