seeking advise for alternative for a permeant address

Once you have a bank account established, you could pay for a service, such as Mailboxes Etc, and have them send on mail to you.

If you're travelling and want mail to be sent for your collection, you can use "post restante" in many countries to have mail sent to a local post office to await your collection.

Hi, I'm thinking of backpacking around Europe for a while and won't have a permanent home address. I'm also in the process of opening another bank account, and I'll likely need to update my information, including my National Insurance (NI). Is there a way to obtain an address that will be accepted in most places and where I can receive mail? I've already tried a PO Box, but they informed me that only deliveries are allowed, and nothing more.

but the main issue is me using my address i want a new one, one that is not from family or friends. I head you can use air b&b but I'm not sure how that goes.

Thank.

You can't use an Air BnB. The problem is that once you have attached banking to an address, any financial problems can be connected to other people who live there. So no-one you don't know will (sensibly) allow a stranger to use their address as a permanent address if they aren't friends or family. It's the same reason homeless people have such problems getting back into work, they need a permanent address. You really need to find friends or family who will allow you to use their address.

yeah thanks. but what about people who live in vans how do they go about it probably friends and family but there must be an alternative :/

It shouldn't work like that -- the only way to get a financial association with someone should be by holding a joint financial product with them -- e.g. a joint bank account or a mortgage.

Look up what people who live on narrow boats do. The ones that don't have permanent moorings and have to move every couple of weeks must have a system.
