"Your transaction failed because the shipping address you entered could not be validated"

I am trying to buy a Steam Deck but I keep running into this error. I never had any issues with my address on other Steam purchases or anywhere else. I tried modifying my address multiple times but nothing works. Steam support has been unhelpful so far, saying I am in an unsupported region, so they cannot provide help. I am in Lithuania, an EU country, and I've seen others ordering to it https://steamcommunity.com/app/1675200/discussions/0/3824161508145366870/ Is there any way I can verify my address with Steam in advace?

I went back to Steam support, and they advised me to write my zip code like this LTXXXXX (before I had tried LT-XXXXX, and LT XXXXX). I was trying to buy a refurbished Steam Deck, and they went out of stock before I could try this, so I am still waiting until they restock. Let me know if this works for you!
