Neighbor spoofing protection
Neighbor spoofing is when spam callers fake a number that looks close to yours. Block Guard now treats this as one part of a bigger anti-spoofing stack that also includes STIR/SHAKEN checks, campaign suppression, logs, and allow rules.
In app
Neighbor spoofing is an explicit product control
This is not implied by a generic spam switch. Block Guard exposes neighbor-spoofing protection as its own layer so you can see where it fits alongside carrier verification and known-spammer checks.
Scammers use local-looking numbers because people still answer them more often. That makes neighbor spoofing one of the most common patterns behind robocalls and scam calls.
How Block Guard handles spoofed local numbers
- Neighbor spoofing protection looks for unknown numbers that mimic your area code and prefix.
- Anti-spoofing / STIR/SHAKEN gives you a separate carrier-verification signal.
- Rotating prefix campaign protection helps when many similar numbers cycle through one prefix.
- Call storm suppression temporarily quiets rapid unknown-call bursts.
Use precise rules, not just one-off blocks
- Block exact numbers when one caller keeps returning.
- Block similar numbers by same prefix or same area code from the blocked-call detail screen.
- Use wildcard or regex rules if the scam pattern is broader than a single number.
- Whitelist family, work, and real local businesses so strong spoofing rules do not catch them.
What to review after a spoofed call
- Blocked Call Log explains whether the call matched neighbor spoofing, anti-spoofing, known spam, or another rule first.
- Protection Center helps you see if the big protections are enabled.
- Analytics shows whether the same local pattern keeps coming back over time.
