Your landline call blocker is doing a great job keeping robocalls and telemarketers at bay. But like any protective tool, it performs best when kept up to date.
So how often should you refresh or review your blocked list? The answer depends on how many calls you receive and how your device is configured. Let’s break it down.
Why It’s Important to Refresh Your Blocked List
Scammers constantly change numbers to bypass filters. Keeping your blocked list updated ensures:
- You’re blocking the latest scam callers.
- You don’t run out of memory space.
- Legitimate numbers aren’t accidentally blocked.
The FCC reports that robocallers generate billions of new numbers every month — staying proactive keeps your protection relevant.
Summary: Refreshing your list helps your device keep pace with new scam numbers and maintain smooth operation.
How Often Should You Refresh the Blocked List?
The ideal refresh rate depends on call volume:
| Call Volume | Recommended Refresh Frequency |
|---|---|
| Light (few unwanted calls) | Every 6–12 months |
| Moderate (weekly nuisance calls) | Every 3–6 months |
| Heavy (daily scam attempts) | Monthly or as needed |
Many users check their lists quarterly — just like reviewing passwords or bank statements.
Summary: Refresh your blocked list every few months or monthly if you receive frequent scam calls.
How to Review and Refresh Your Blocked List
Most CPR Call Blocker devices make this simple. You can:
- Scroll through your blocked numbers using the display screen.
- Delete any legitimate numbers added by mistake.
- Manually add new scam numbers you’ve received.
- Perform a full reset if your list is full or outdated.
A quick refresh takes just minutes and ensures you’re still fully protected.
Summary: Review, remove, and add numbers regularly to maintain accuracy and efficiency.
When Should You Update the Preloaded Scam Database?
Devices like CPR Call Blocker V100K come with over 100,000 known scam numbers preloaded. These lists are extremely comprehensive, but upgrading every 12–18 months ensures protection from newer, more sophisticated scams.
You should update or upgrade if:
- You’re receiving more scam calls than usual.
- Your current device is several years old.
- You’ve switched to a VoIP home phone system.
Summary: Upgrade every 12–18 months to stay ahead of new robocall tactics and technology changes.
Signs It’s Time to Refresh or Reset
- You’re receiving more unwanted calls again.
- The same blocked numbers keep calling back.
- The device memory is full.
- You’ve added hundreds of new numbers manually.
Refreshing helps free up memory and ensures only active scam numbers remain blocked.
Summary: Rising call volume or a full memory are clear signs your list needs refreshing.
What Happens If You Don’t Refresh Regularly?
Neglecting updates won’t stop your blocker from working, but you might:
- Miss newly emerging scams.
- Run out of memory for new entries.
- Accidentally keep legitimate numbers blocked.
Regular refreshes keep performance consistent and protection current.
Summary: Skipping updates may reduce effectiveness over time as scammers evolve.
Extra Tips for Ongoing Call Protection
- Register your number on the Do Not Call Registry.
- Report unwanted calls to the FTC or FCC.
- Use carrier-level filters (AT&T ActiveArmor, Verizon Call Filter).
- Enable Caller ID for accurate identification.
- Whitelist trusted numbers so important calls always go through.
Summary: Combine regular updates with registration and carrier tools for complete scam prevention.

Keeping your landline call blocker’s list refreshed ensures your device stays effective against new scams and robocalls. A quick review every few months and an occasional upgrade keep your home phone protected for years to come.
