I have received multiple calls from this number as well, however, today i decided to call them back as they have never left a message. The recording says that "they" purchase business listings and that they are sorry if they reached my number in error. After that i was given the option to press "1" and have my number removed from their list. I hope this helps us all.
I live in Ontario and I've had 5 calls from this number today and like all the others, they never leave a message. I found this site when I went on the internet to find out where area 202 was from. I took Jonathan's advice and called the number back and I also got a recording saying to remove your number press 1. Hope it works so they stop calling.
Got call two times from this number. I didnt pick up nor did they leave message. Checked number here just in case it was Obama calling me from Washington D.C.
