Have customers called to say your business number appeared on their caller ID, even though you never called them? Someone may be spoofing your number. Caller ID spoofing means a caller can make a different number appear on the recipient’s screen. It does not, by itself, prove that your phone system was hacked or that your number was transferred away.
Why caller ID is not proof of identity
A caller can impersonate a bank, vendor, executive, IT technician, or even your own office number. That is why BCS tells businesses to verify unexpected requests through a contact method they already trust. If someone calls asking for a password, MFA approval, remote access, or a wire transfer, hang up and call the organization using a number from its official website or your existing records. Do not rely on the number displayed on the call or one supplied by the caller.
What to do if your business number is being spoofed
- Confirm the pattern. Ask callers for the date, approximate time, number they saw, and what the caller said. Keep examples for your phone provider.
- Check your own system. Review call logs, account access, forwarding rules, and any unusual international or premium-rate charges. Spoofing alone does not require access to your system, but unexpected activity deserves investigation.
- Contact your provider. Report the examples and ask what caller ID authentication and abuse reporting options they offer. Providers can investigate originating traffic, although there is no instant switch that prevents every spoofed call.
- Warn your team and customers. Tell employees not to treat caller ID as verification. If customers are receiving impersonation calls, publish a brief notice explaining how to reach BCS through known channels.
- Report suspicious calls. The FCC’s caller ID spoofing guide and the FTC’s imposter scam guidance explain reporting and verification steps.

Frequently asked questions
Does spoofing mean my phone system was hacked?
No. A caller can falsify the displayed number without entering your phone system. Check for suspicious call records, forwarding, account changes, and charges to determine whether anything else happened.
Should employees call back the number shown on caller ID?
For a sensitive request, use a verified number from your own records or the organization’s official website. The caller ID display can be falsified.
Can BCS stop every spoofed call?
No provider can promise that. BCS can help investigate your phone environment, coordinate with the carrier, and put practical verification steps in place.
