How to Know Guardian’s Monitoring Center is Calling

When your Guardian system’s alarm goes off, the monitoring center jumps into action. In many cases, one of the actions they take is contacting you and the people on your emergency contact list. Since an emergency may be occurring, we want to be sure that we get in contact with you as quickly as possible.

To make connecting with you easier, we’ve changed the phone number you’ll see when you are being called by the monitoring center. When you’re receiving a call from Guardian’s monitoring center, you will see the number 800-364-3616 and, if you have Caller I.D., you will see the word “GUARDIAN” displayed. This number will only be used for monitoring center calls. When you see this number, you are receiving   an important call about your alarm system.

Make sure you don’t miss a security center call

  1. Program the number 800-364-3616 into your cell phone so you’ll know who’s calling at a glance.
  2. Write this number on any lists of important numbers you have in your home.
  3. Tell your emergency contacts to program this number in their phones.
  4. Use this number to notify the monitoring center of a false alarm or to return a call from the monitoring center.
  5. Never place this number on your “Spam” or “Block Caller” list.

Because this number is only for the monitoring center, you should not use it for your customer service needs. You can always call 1-800-PROTECT for your other Guardian needs.

Why we changed our security monitoring center number

Spam calls are becoming a bigger and bigger problem, especially for cellphone users. We’ve found that some people don’t even answer their phone if they don’t recognize the number. Touching base with customers and emergency contacts are an essential part of how our monitoring center works. Unifying to one new number allows you to program it into your phone and always know when Guardian’s monitoring center is calling.

We’re proud of our U.L.-certified monitoring centers. Both are located in the U.S., have achieved prestigious Five Diamond certification, and are staffed by highly trained, U.S.-based operators, all who work directly for Guardian Protection Services, right inside our monitoring centers here in the U.S. We hope this simple change makes it even easier to interact with our monitoring center.

    I suggest creating a vcard and QR code so people can quickly add this to their contacts. I just added it to my Google Contacts under “Guardian Alarm Monitoring Service”.

    This information is of no value to me. I have a land line without caller id. I do have an answering machine. My cell phone does not function at my residence.

    Hopefully, we will be receiving this info in the US Mail…. and hopefully the phone number I call into Guardian hasn’t changed as it is on all the litt le cards I have near all my phones..If not, I would hope new ones will be printed and mailed out to me.

    Carol, the number you call in on isn’t changing. It says so in the article.

    This change is because of all the scammers calling cell phones. It’s as bad as spam in email. I don’t answer a number unless I recognize it. So it’s great that Guardian is using a single well-known number for contacting us.

    Note that scammers can still forge Guardian’s number, because caller ID is not secure and is easily forged. A clever crook could call us pretending to be the monitoring service to get our password. Perhaps we need two passwords on our account. A second one for Guardian to identify itself to us, just as we must prove our identity to them.
