The 720 area code is being used for fake legal threats and sheriff jury duty scams. Fraudsters claim you have a warrant for missing jury duty and must pay a fine to avoid arrest.
Threatens to serve a "faxed complaint" at your workplace, declaring you "officially notified."
"Voicemail saying they've received a fax with a civil complaint against me and threatened to show up at my home or place of employment."
Uses real officer names to demand $1,000 MoneyPak bonds for fake missed jury duty.
"Got a call from the number of the Boulder County Sheriff's office and a man claiming to be a deputy officer... He knew my full name and home address and told me to call back on his extension... and claimed I had 2 warrants out for my arrest for missing jury duty... He wanted me to get a cash card with $1000 to pay my bond."
Threatens cancellation of SSN due to illegal activity and pressures you to "press 1".
"I returned the call I was told my social security number has been compromised and involved in illegal activity. They asked if I knew of any activity like this with my SSN and I said no. They began to tell me how they can help. Scam."
Claims a 941 assessment or federal withholding tax lien requires immediate resolution.
"Jimmy called to say it was a Federal withholding matter and it was his final attempt to reach me and left a number."
Demands untraceable cash payments within 30 minutes to stop a delinquent shut-off.
"Claims to be Xcel Energy saying the power will be shut off today at this address. Contacted Xcel directly and they say all is good with our account."
A phantom debt tactic claiming a delivery agent failed to get signatures and you are "non-compliant."

Repeated robocalls (3-4x daily) for vehicles you don't own; pressing opt-out triggers more calls.
"I get SO many calls from this company about the warranty on my car! I've told them to stop calling. Asked them to stop calling. Told them I don't need the warranty/don't want it, etc. etc. They don't listen. I block one number and they call from another number."

Area code 720 covers the same geographic area as area code 303. This includes Denver, Boulder, and their surrounding suburbs in north-central Colorado.
Area code 720 is part of an overlay complex with area codes 303 and 983 , meaning they serve the same geographic region. Area code 303 was the original area code, established in 1947. Area code 720 was added in 1998, and area code 983 was activated on June 17, 2022. Ten-digit dialing is required for all calls made within this service area.
Introduced as an overlay for the north-central Colorado metro, 720 covers the same Denver-Boulder-Aurora geography as 303. Callers include Denver Federal Center administrators, DaVita scheduling staff, and CU Boulder alumni outreach teams.
