Critical Installation Information

Last Updated :

Guam is across the International Dateline from the mainland United States. Guam's time zone is GMT + 10 hours. Guam does not use daylight savings time. Guam is about three hours by airplane from Tokyo and Manila, four hours from Seoul, Hong Kong, and Taipei, five hours from Saigon, Singapore, and Bali, and six hours to Bangkok, Sydney, and Auckland. Going to the other side of the International Dateline, it is seven hours by air plane to Honolulu, Fiji, and Samoa, and eight hours to Tahiti.

Assignment tours are 24 months for unaccompanied/single and 36 months for accompanied; check with your MPF for the most current information.

Passports and Visas

Ensure member and/or dependents have the required passports and/or visa prior to final out-processing. Member and/or dependents are not allowed to final out-process without the required passports/visas in hand for themselves (if applicable) and/or dependents. Members electing the accompanied tour will not be permitted to out-process without having the required passports/visas in hand for themselves (if applicable) and/or dependents.

These actions are necessary to prevent unforeseen hardships to the military members and their families. Therefore, as a last reiteration, it is essential, members do not out-process without having the appropriate passports/visas for themselves (if applicable) and/or dependents.

Making Phone Calls

To call Guam commercially from mainland United States, just dial 1, the area code for Guam (671), then the telephone number. Commercial - 1 (671) 366-xxxx (Guam has a U.S. area code). DSN 315-366-xxxx, Operator ext.-1110. To dial a commercial local call from on base, you must dial 99 + number. Example: 99 + 653-xxxx.


If en route and the flight is delayed, contact the Military Personnel Flight (MPF) Employment Office at DSN 315-366-3561, or your sponsor. For other emergencies, contact the American Red Cross for official verification of emergency. ARC will contact an Andersen AFB representative, who will notify your Command representatives of your present situation.

Special Needs Family Members

Stringent overseas medical screenings are required for all military, DoD Civilians, and command sponsored family members reporting to Guam. Individuals who evade or avoid medical screenings, who mislead medical screeners, or who fail to enroll in the EFMP when required will be dealt with by the Command on arrival at Andersen.

Non-Command Sponsored Family

Members who bring non-command sponsored family members to Guam do so at their own financial/medical risk!


School Age children and military spouses need a clean IPPD test (Tuberculosis Screening Test), especially if working in the beverage industry, medical community, or around children.

Exotic Pets

If you possess a pre-Endangered Species Act animal that you want to bring to Guam, contact the nearest Federal Parks & Wildlife office. Without proper documentation, you may not be able to get your animal back into the States. Pet quarantine on Guam is currently 5 days. It is expensive to bring an animal to the island.

Certified Birth Certificate or Passport

Many patients are MEDEVACed from Guam to U.S. hospitals in Japan or Okinawa. While Japan will not keep an emergency case from entering the country, the accompanying family member (if not active duty) will be required to have a passport. Also, the patient will need to obtain a passport to leave Japan. Guam Immigration and Naturalization Service do not recognize military dependent ID cards as valid proof of U.S. citizenship; therefore, we recommend all dependent travelers carry a certified Birth Certificate or passport.
