If prospects are seeing labels like "Spam Likely," "Scam Likely," "Fraud Risk," or "Robo Call" when you call them, your calls may be going unanswered or blocked entirely, even though you are making legitimate sales calls.
This article explains why this happens and what you can do to reduce it.
Why Your Calls Get Marked as Spam
These labels are not added by Saleshandy. They are applied by:
The prospect's mobile carrier
Third-party analytics engines that carriers use to detect suspicious call patterns
Apps installed on the prospect's device (such as Hiya, First Orion, or similar spam detection apps)
Once a number gets flagged, either because of high call volume, consumer complaints, or patterns that resemble robocalling, it is added to a list that triggers the spam label automatically on future calls.
What Triggers a Spam Label
Common reasons a phone number gets flagged:
High call volume in a short period: Making a large number of calls from the same number in a short window looks like automated dialing to carrier systems
Low answer rates: If most calls go unanswered, carriers treat this as a signal of unsolicited outreach
Consumer complaints: If a prospect manually reports your number as spam in their phone app, it contributes to the flagging
Calling outside normal business hours: Calls at unusual hours are more likely to be flagged
Newly purchased numbers: A fresh number with no history that suddenly makes high volumes of calls can be flagged quickly
Calling the same number repeatedly: Multiple unanswered attempts to the same contact in a short window raises a red flag
How to Fix and Prevent Spam Flags on Your Numbers
1. Review Your Calling Behavior
This is the most important step and entirely within your control.
Spread your call volume: Avoid making hundreds of calls from one number in a single day. Distribute calls across multiple numbers if you have them.
Do not call the same prospect repeatedly: If a prospect does not answer after 2–3 attempts, move on or try at a different time.
Call during business hours only: Stick to normal working hours in the prospect's timezone.
Keep your contact list clean: Remove invalid numbers, numbers that consistently go unanswered, and numbers that have been marked as wrong number.
Use Local Presence: Calling from a number that matches the prospect's area code increases answer rates and reduces the likelihood of calls being ignored or flagged.
2. Use Multiple Phone Numbers
If one number is getting flagged, rotate across multiple numbers using Saleshandy's number rotation feature. This distributes your call load and reduces the volume associated with any single number.

3. Register Your Number with the FCC
For US numbers, you can register directly at freecallerregistry.com, a free registry established by the FCC that covers the main analytics companies supporting major US wireless carriers. This can remove a negative label from your number.
Note: This is available for US numbers only.
FAQs
Can I purchase a new phone number if my current one is flagged?
Can I purchase a new phone number if my current one is flagged?
Yes. If your number has been heavily flagged and removal is not working, you can purchase a new number from the Phone Numbers section and reassign it to your account.
How long does it take for a spam label to be removed after registering?
How long does it take for a spam label to be removed after registering?
This depends on the analytics engine and carrier. It can take anywhere from a few days to a couple of weeks. There is no guaranteed timeline.
Does using Local Presence prevent spam labeling?
Does using Local Presence prevent spam labeling?
Local Presence improves answer rates by matching your number's area code to the prospect's region, but it does not prevent spam labeling on its own. You still need to follow clean calling practices to avoid being flagged.
Can I keep using a flagged number while waiting for the label to be removed?
Can I keep using a flagged number while waiting for the label to be removed?
Yes, but answer rates will likely remain low during this period. We recommend distributing calls across other assigned numbers in the meantime to maintain your outreach volume.
Will registering my number guarantee it won't be flagged again?
Will registering my number guarantee it won't be flagged again?
No. Registration improves your standing with carrier analytics engines but is not a permanent allowlist. If call patterns that triggered the original flag return, the number can be flagged again.
