"Invalid Address" when trying to make Steam Payment

I don't know what this issue is, but I've always paid with Steam payment for years, now it's telling me that I need to change my address and that it's invalid whenever I try to alter the smallest thing, not letting me progress to my payment. I've literally never changed countries or the province I live in, in my entire life.

I just paid for my subscription with Steam Payment and had no issue, I was not asked to update my address or anything.

Are you using Steam Wallet or Auto-Renew to pay, if Auto-Renew, I would logout and restart Steam, the same if logged in to the Steam site, and then select on the MogStation "Steam Wallet" and when it loads up the site, select to "Add Funds" to the Wallet and then it should skip Square Enix's payment processor and be successful.

I bought a game time card to try to get past this and it still redirects me to change my address and then saying it's invalid... I'll just wait a week or so and hopefully this is fixed.

EDIT: Well I fixed it, I had to change my address to a nearby city, apparently the new processor thing doesn't recognize rural towns. If anyone else is having the same issue, try that.

From what I've read, you need to check your actual address in a postcode finder such as for NA, USPS official site and type in your address, it should re-correct it to the updated format.

Though for Steam users, if you use the Steam Payment option on the main page, you will not be asked to update anything, as Steam processes the payment, not Square Enix, so why you got asked to change your address I don't know.

I updated my matching address and no fix for me

Login to the MogStation, select Steam Payment from the landing page, select Entry or Standard and then 30 days, select Steam Wallet then once it asks you to login to the Steam website simply click "Add Funds" if the Wallet doesn't have enough, charge it, done.

You can add funds from multiple sources, none of which have anything to do with SE.

Unsure if selecting Auto-Renew requires some form of check, but it should not.

How are you getting an invalid address error with the Steam version, where in that process I mentioned above?
