Anything with a "543" prefix is from the University of Washington.

It's the University of Washington. They probably want a donation.

Oh, I got one call from 206 543 6539, late afternoon today. Then, same number called me at 8:00 pm tonight. I did not pick up. No message.   I graduated from UW.  If its the official UW alumni association, I wish they would have left a message.  People are more suspicious about those who don't leave messages and keep calling.  This could be false people (criminals) pretending to be the UW alumni office asking for money.... you never know.  Be careful out there!

keep calling and don't leave message.

I answered and found out that it's some form of the University of Washington alumni association trying to collect donations. They also call from a similar number with a different ending digit. I personally think it's sketchy since they don't leave messages or have a voicemail when you call the number back, so I don't donate to them over the phone. I only make donations through the official UW fliers that come in the postal mail.

Got a call at about 7:45.  No message.  Exact same number.  And it isn't the first time.

Yep, keeps calling me too.  I am going to pick up next time.

Over 5 calls and no message

keeps calling and doesn't leave message.
