Here are some other abbreviations you might see:
* Sta. (Less common, but sometimes used in formal documents)
* State (Sometimes used in informal writing, especially when the abbreviation is obvious from the context)
It's important to note that the abbreviation St. is typically used when referring to a state as part of a formal address, such as "123 Main St., Anytown, CA".
In other contexts, it's best to use the full word "state" unless there is a clear reason to abbreviate.
