Who called from 2021145863

I've received in the last week on my land line an area code with 202 and it says Invalid Number.  Each of these are off a few digits after the area code of 202.  I don't answer them, and I just keep blocking all these numbers.  I also found when I entered the Publishers Sweepstakes Clearing House that I began to receive junk emails and now unwanted telephone solicitations.

Just block the entire area code-save time and blocking spaces.

I answered but no one would say anything, so I hung up and blocked the number. Going to report them to DoNotCall.gov.
