“Unknown number” is already a barrier. Dirty data makes it worse.
Consumers are tired of spam, spoofing, and unwanted calls. If your business is calling old or misaligned contacts, you’re more likely to be ignored, or worse, reported.
Call-blocking apps and crowdsourced data account for nearly half (49.4%) of the flags we monitored in 2025. This high percentage suggests that dialing behavior attracts negative flags.
You have considerable control over your business’s dialing behavior, so adopting ethical dialing practices will significantly reduce the risk of your numbers being flagged.
Some of the most important strategies to avoid flags and call with confidence include:
Proper Agent Training
Train your agents to identify who they are and why they’re calling at the beginning of each call. Also, teach them how to use empathy during calls. How agents speak to people could make the difference between someone reporting your number and simply ending the call.
Diligent Data Hygiene
Proper data hygiene involves removing any leads on the Do Not Call Registry (DNC). Remove any numbers on your internal do-not-call list and any duplicate numbers from your lead lists. Use the Reassign Number Database (RND) to ensure you don’t call the new numbers of people in the DNC. You’ll also need to update your CRM to make sure it has the same information as your call lists.
Maintain Compliance Standards
All companies placing outbound calls must comply with certain rules. For example, agents can only place calls between 8 a.m. and 9 p.m. (local to the consumer). You might also need to follow additional regulations for your industry. For instance, your agents will need to follow HIPAA guidelines when making calls about healthcare topics.
Calling the right contacts and properly identifying the reason for each call matters because every unnecessary call can erode trust and increase the likelihood of negative feedback.
