It is an Arapahoe County Clerk, and she was reminding me of a court date I have on Wednesday.

This is a phone screening technique.  Ive received a call from this number numerous times.  As stated above anyone can use this program to block their call. It is common for government agencies to use, but with today's technology anyone can use it. I suggest ignoring this number. If it is important they will leave a message.  

Called on a sat for my husband from Arapahoe county courts ...if this was ligit they would know that hes been incarcerated for over 4 months now and his case has already been dismissed so no reason to call him. When I told them this is his wife they hung up. Called from 7200000000

Keeps calling after hrs and on weekends for my husband

Got a call from (720) 000-0000 at 11:09pm, lasted 40 seconds. This girl screamed into the phone for a "Nancy" or a "Cousin", I couldn't make out what she needed or who she was looking for, she screamed saying she needed help, asking her who she was looking for she immediately calmed down and I told her she had the wrong number, whispering to her friend "It's a wrong number" followed by a few giggles they then hung up. Not a professional number, not a scam, just utterly annoying.

i wish i could block unwanted BS calls

It's Arapahoe County Sheriff's Dept.
They left a message for me to call them back about my neighbors

I got the same call from the arapahoe county district office....?

called my Verizon Wireless cell 11/22/12 at 2 PM...when I answered they hung up...if this call is from Colorado as the above mentions it is strange as I live in New Hampshire and have never been to Colorado

Just got a call. The lady claimed to be from Arapahoe county sheriff's office. She had my full name right and was calling about some business I indeed have with them. So I think the call is legitimate.

I think this is a way for anybody to block their callback number.  Just got one today from someone today who was legit, but perhaps paranoid.

Just got a call from 720-000-0000 on my cell phone. The guy gave me a first name only said he was from Homeland Security in Denver CO about an immigration problem with my son.  Asked him to name my son and he gave me a wrong name and birthdate and then apologized for the mix up.  Told the guy if he was truly from Homeland Security then he shouldn't be mixing up ID's.  I should have played along with this moron to see what kind of scam he was working...

herrast me about court order

Just got a call from a guy saying a first and last name, then confirmed if i still lived in the same city? Told me that some girl had gone missing and if i had knew her. pretty weird that they knew my info?

must be a spoofed number

Just got a call from 720-000-0000 at 12:47am.  I freaked out because it was so late, and hung up on the call without answering.  Whoever or whatever it was did not leave a voicemail.  What the heck kind of phone number is that anyway?

This number has been calling me 5-6 times per day for the last couple of days.  I finally answered, and they asked for my husband, so I asked who it was, they said they were calling from the Colorado Democratic party.  I said my husband isn't a democrat, but thanks anyway!!

got a call from this number calling for a guy that was part of a criime or something like that

I received a call from this number and the caller left a voice mail.  It was from the Arapahoe County District Attorney's office - Victim Advocate Unit (I was a victim of a crime).  Not sure why the caller ID was all zeros, unless they blocked their number.

I just got a call from 720 000 0000... on my cell phone...
They hung up as soon as I answered....?

Got this call Feb 26 at 4PM MT
