Community urged to refrain from calling back international phone number


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

The international phone numbers may begin in area code 881 or 882 and are seemingly “spoofed,” which means it is imitated or disguised to appear as a different number.

The community is reminded to remain vigilant and continue to follow these tips:

  • Do not answer any unexpected calls from international or unusual numbers;
  • If you have a missed call from an international or unusual number with only one ring, do not be tempted to call back; and
  • 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.”
