@astroroyalscot.bsky.social My cousin sent me a cash gift for my confirmation when I was 15 (1992) addressed only with my name and the municipality I lived in. No post code. The municipality was not a part of my address at all, and he spelled it wrong and instead used the name of a completely different municipality in a different part of the country.
I still got the letter though! And my cash gift. 😁
