Caller ID: Poolsville MD

The CID name is generated from a telephone company database using the caller ID number.
A destination provider may display no name or just the geographic location of the provided telephone area code on caller ID (e.g., "ARIZONA", "CALIFORNIA", "OREGON", or "ONTARIO"). This often occurs where the destination carrier is a low-cost service (such as a VoIP provider) running no database or outdated data in which the number is not found.

Missed calls could be from anyone.
Scammers, telemarketers, debt collectors, pranksters, surveys, notifications, alerts, wrong number, etc. Some use neighbor spoofing so it appears that an incoming call is coming from a local number, or spoof a number from a company or a government agency that you may already know and trust. If you answer, you can find out who it is or what they want. Just be aware some may use scam scripts to try to steal your money or valuable personal information, which can be used in fraudulent activity.
