Why Does My Phone Think It's Clairvoyant?

My phone autocorrected a number today . . . I was trying to text the digits 3241 (part of an address) but my phone kept changing this number to 532411 . . . and this makes no logical sense, as this new, autocorrected number isn't the zip code of the address, nor is it the area code of phone numbers associated with this place . . . if anyone knows why my phone (older model Samsung Galaxy) thinks it can read my mind when it comes to numbers, please explain.
