I have an address specifically for that—it's just one letter and a few digits, redirecting to the main account. Works like a charm. Especially when the native alphabet in the country is not Latin and laboriously explaining which letter is which is a meme from the phone calls era. Whereas I can just call digits by the names in the local language, and everyone is familiar with hearing them.

Meanwhile, with my main-ish addresses, I've been told that they look like a random jumble of letters or a password. And once I've given one of them over the phone, took ten minutes easily—with confusion as to even how many letters are there.
