Not sure if this is common knowledge and I'm just late to the party here, but found out you can quite easily register for a virtual office pretty much anywhere.
For example, I work with realtors in America when I am based in UK (since commissions are much higher over there), this can cause issues when trying to register for several services since the company is not based in the same country.
What I've found I can do is get a virtual office (prices vary, I've found some for 9.99/mo and some for 20-30/mo) then use that office to register for things like caller registry.
I've linked a few examples below for anyone interested:
