Actually, there is a decent supply of numbers for something like this to last a while.
The key is that they are using numbers from lightly used area codes (e.g., rural Iowa). It's the heavily populated places that are running out of numbers and requiring new area codes.
Note that these disposable phone services aren't new. About five years ago there were a couple that were free (I suppose their plan was to make money selling ads, etc.); one was Numbr (later known as iNumbr).
Today, pretty much all of them are paid services. The 'Burner' app's rates are quite competitive.
