Smartphones May Filter Your Number

Many smartphones will show a business number as spam in a few different ways. The “SPAM” designation may be displayed in three different ways: Scam Likely, Spam Risk, Spam Likely. This occurs because phone carriers will have a list of many numbers that have been determined as potential scam risks. This is based on the history of the number. However, no one takes a serious look at these lists when the numbers reach new people. Plus, there are no services or databases available to manage how this system works.

Why Is My Business Telephone Being Given The “Spam” Designation?

There are many reasons that your business could be having a Spam designation. In fact, there are so many that we are only going to list the top three. 

  1. The amount of outgoing calls per day from your number. 
  2. A person has flagged your call from your business number. The person can report a number to their carrier as a spam number. 
  3. Your outgoing caller ID is not set to display properly or is not completed. This can cause a number to be automatically flagged as a spam number.

Each Carrier Handles SPAM Differently

Every carrier will have an app or feature that comes on the device when it is purchased. When someone calls a phone, the carrier will check the number through a system. This system is the database of numbers that have been reported as scam. If there is a number in the database that matches the number a business is calling from, it will be tagged. This means that the person who is receiving the call will see Scam Likely on their phone. This means that the recipient of the call can choose to answer or not. 

There are even more features available for spam calls. Carriers will ask customers if they would like to be part of this feature. It will block all calls that would pop up as Scam Likely. This means that the recipient of the call will never know that they were dialed. There are paid and free versions of this service from every carrier. Keep in mind that there are third-party apps that will allow you to do almost the same thing. 

Keep in mind that the Scam Likely ID that pops up on a cellphone is not always correct. Some calls are legitimate and will be marked as spam simply because someone has reported the number as potential spam. Remember, if someone reports a number enough for potential spam, the number will be flagged. 

Many phone carriers are also working on another feature. This feature will detect large amounts of phone calls from a common calling ID. This algorithm will allow the carrier to mark these numbers as Spam Likely numbers. 

How To Fix If Your Phone Number Is Marked SPAM

If you are experiencing this problem, the first thing you should do is change your number. You need a new number to replace the one that is being flagged as potential spam. Keep in mind that even if you change your number, the same thing may happen. There is always a history behind numbers that we know nothing about. If you are worried, ensure that the new phone number is working properly. Make a few calls and see how the caller ID shows up on a cellphone.

Is It Possible To Resolve The SPAM Designation Quickly?

Protecting Your Company Phone Number And Preventing Your Business From Being Blocked

The reason a phone number gets blocked is because of suspicious activity. This includes unusual calling patterns. A business may be flagged because they are making legitimate calls all day and have not registered their number. Businesses use a similar pattern to numbers that are spam. 

The list below has some tips on how to avoid being blocked.

  • The outgoing number for your business should always be valid and legitimate. 
  • Always ensure that your caller ID is valid. .
  • You should not substitute phone numbers in a caller ID that you do not know. 
  • Avoid having an outgoing number that is featured on the Do Not Call list.
  • Ensure that you are not making numerous calls in one minute. This is especially true if you are making calls that are not within normal business hours..
  • Do not call numbers back to back too many times. Ensure that you are allowing time between calls to ensure that you are not flagged. 

Another thing that you should do is check with different phone companies as well as third-paty apps analytics. These will show different complaints that have been made against the phone number that you use to call people from your business. 

When you are leaving a message, you should make sure that you have the same call-back number for each. You want to be consistent. It may also be beneficial to add other contact information that a recipient can use to report their concerns.

Here is an example, a customer support center will be less likely to be flagged based on complaints if there is a distinct number that is not linked with the telemarketing numbers. If these two departments are linked, the phone calls may be flagged as spam.
