We moved from IN to PDX over the winter (sold/bought a house)...etc. Ever since then I've been receiving these calls too. 75% are IN numbers with the same 3 digit combo that I have. Most are health insurance, car warranty, or even Windows computers calls. (I always laugh at those b/c i've never owned a PC in my life, Apple's since '87). I usually don't answer but sometimes I do. I always block that callers number after they call but that doesn't seem to stop them from trying different numbers.
