Community Urged to Practice Caution with Calls from Unknown Phone Numbers

The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) and the Mariana Regional Fusion Center (MRFC) are closely monitoring reports of local telephone numbers receiving calls from unusual or unexpected numbers.

The phone numbers reported are seemingly “spoofed,” which means it is imitated or disguised to appear as a different number. Reports received include international phone calls with area codes 338, 882, or 972. Other numbers may be included but not reported at this time.

Not all calls from unusual numbers should be regarded as suspect. To avoid missing important calls, familiarize yourself with numbers important to you and your household such as insurance agencies or others that you regularly deal with.

Remain vigilant and continue to follow these tips:
  • Do not answer calls from unknown international or unusual numbers.
  • If you answer the phone and the caller - or a recording - asks you to hit a button to stop getting the calls, you should just hang up. Scammers often use this trick to identify potential targets.
  • Never give out personal information such as account numbers, Social Security numbers, mother's maiden names, passwords or other identifying information in response to unexpected calls or if you are at all suspicious.
  • Use caution if you are being pressured for information immediately.
  • If you have a missed call from an international or unusual number with only one ring, do not be tempted to call back
  • If an international or unusual number calls you with only one ring, block the number, if possible

Residents are advised to report any suspicious activity or social media posts relating to the subject to the MRFC online at or email or call (671) 475-0400, following the Department of Homeland Security’s campaign, “If You See Something, Say Something.”
