I got a missed call from this number.
It's from channelview

I answered and it was a guy talking about some kind of benefit for the families of fallen police officers and then he said something about sending me a sponsor card then I hung up

Charity call for officers , I respectively declined my information.

Called and didn't leave voicemail. Blocked the number

It's another faux "charity" trying to get you to send money, only a few pennies of which any officer's family will ever receive.  I asked for the official name of the charity so that I could examine its IRS Form 990 online.  That's when the caller hung up.  If they were legit, then they wouldn't be afraid for me to check them during the call.  That they immediately hung up, when I insisted to seeing their officially filed Form 990 (if it exists), told me all I need to know about them.
