Shows number is avaliable  when doing a reverse lookup. It hails from Baltimore Maryland. More than likely a VoiP assigned number that was stolen then spoofed.  The number itself when called back is from Home Health house calls, and you hear the voice that tells you that you have reached them and says first of all that if you have a medical emergency to dial 911. Gives you a list of choices to reach specific departments. I didn't stick around long enough to do much more than find out what the thing was. Strangely, I have recieved many from Washington DC also with spoofed VOIP numbers as well, feeding the theory that it is a spoofed number. Quick crash course in spoofed numbers... A cellphone can say anything you want it to with a quick change of settings. You can create it to say unknown as well. Some spoofs that work are cellphones that have no service but use a voip and use as well as recieve calls from that number. When you call them back, it signifies to them that the line they called is active and in service. These numbers work off of data from call center voip lines, using specific numbers from a random call center data to call and offer services. Unless you can call from a cell that is identified as private number when other callers call in, or a landline that can do the same, I advise that you never call them back. If you don't know the number, do a reverse lookup. If that turns up nothing then report it instead of trying to sleuth it yourselves. :) Have a nice day!

Been receiving calls from 443-853-6898/ also they refer to call back # 866-686-2504. Stating United Health care/AARP House Call services. They ask to verfiy information, DO NOT GIVE ANY. Just ask for a call back ph#.
Cal the insurance number on your policy to verify the above numbers and they are providing this "house call service".
Beware!

This IS a legitimate call and IS a legitimate service.  The company is AARP Medicare Complete which is a Medicare Advantage Plan underwritten by United Healthcare.  Those that are on medicare and have chosen a medicare advantage plan will get calls from this number, which is AARP when 1) they have selected AARP Medicare Complete as their medicare advantage plan or 2) the dates are between Oct 1 and Nov 7 of ANY year which is the open enrollment period for Medicare and it is LEGAL for ANY medicare advantage plan company to call ANY medicare recipient to offer their service.

I let this go to my answering machine and the message was left that it was United Healthcare House Calls. I called back and asked what it was about they said they would arrange for a health care worker to come to my home for a 45 minute health assessment. I did not give them any info and called my insurance company. My insurance company had no connection to this number and they made notes to send to their investigation dept.  I also notified my police dept.  They were aware of the scam but I was the first in our area they heard from.  THIS IS A SCAM.

Calling and bothering old, disabled people very early in the morning is not COOL.
