How to Avoid Spam Risk Caller ID Flagging on Your Outbound Calls

There were 6.54 billion robocalls in September of 2021. Keep your legitimate sales calls from getting tagged as spam risk caller ID.

The Spam Problem

According to, 6.54 billion robocalls were made in the United States in September of 2021. I think 1/3 of those were made to my line alone! But seriously, it isn’t a revelation to anyone that spam calls are way out of control. This affects prospects’ willingness to answer the phone and if a call is clearly flagged as spam, forget about it.

Now suppose that your number gets flagged. If you are lucky, one of your prospects might reluctantly answer and tell you that your caller ID is showing up as a "spam" or "spam risk". But how often do you answer a spam call to tell them that it’s flagged as spam? You have to put a process in place to prevent getting flagged in the first place.

Why do my calls show up as spam?

There are two primary ways that your numbers are flagged. The first is from the end-user who uses spam blocking technology on their smartphone to block your calls. The second happens on the carrier level.
It is unlikely that a single lead blocking your phone number using a spam blocker will flag your outbound numbers, but if there are too many, it could permeate through the application database. If there are too many flags, your phone numbers will show as spam.

Carriers are also monitoring caller activity. If your local phone number is making more than ten calls per minute, or 100 calls per day, the phone carrier will likely associate that number with robocalling. And, you guessed it, the phone carrier will label your number as spam, and this will impact your contact rates.

What can you do?

Source Appropriately

For starters, make sure you are sourcing your leads appropriately. If you are capturing web leads, use appropriate opt-in language. Use omnichannel outreach techniques. Don't rely solely on calling your internet leads; employ SMS messaging and outbound emails. If someone is not interested in your services, promptly remove them from your calling lists. In other words, just don’t spam.

Use Multiple Outbound Numbers

If you have a large sales team calling into a large geographic area, make sure you have the appropriate volume of local numbers. For example, it’s advisable not to have a team of ten agents all using the same local phone number for your outreach attempts, as a carrier will quickly flag that number as spam.

Periodically rest your numbers, and the same is true if a phone number is flagged as spam. As soon as you confirm it is flagged, remove it from your outbound rotation.

Set Your Caller ID

Ask your phone provider to update your CNAM (the Caller ID) to your business name if possible. Try placing test calls on various carriers to see which may have flagged you as spam likely.

Register Your Numbers

Lastly, consider registering your phone numbers through major analytics organizations. This move lets the carriers know that you are a legitimate business trying to contact those who use that phone carrier. Importantly, this is not a whitelist, and your phone numbers can still get flagged as spam. It is also important to note that there is no guarantee that your spam flag will get lifted even if you submit a request.
