How to send a fax to Guam

Why fax to Guam?

If your recipient in Guam asks for a fax, you can send signed forms, supporting documents or other paperwork from your phone or computer. Confirm that the recipient accepts your document by fax and check their current fax number before sending.

What you need

To send a fax to Guam with unofax you need four things:

• Your document: PDF, Word, image, or any supported file. PDF gives the best results.
• The recipient's fax number: Guam uses +1 with area code 671. Enter 671 followed by the seven-digit subscriber number. The full international number starts +1 671.
• A payment method: credit card, debit card, Apple Pay, or Google Pay.

No account, no subscription, no fax machine required.

Tips for faxing to Guam

A few things to keep in mind when faxing to Guam:

• Local time: Guam uses Chamorro Standard Time (UTC+10) year-round. It can already be the next day compared with the mainland United States. Send during the recipient's business hours when possible.
• Supported numbers: Use an active, supported fax line. Premium-rate numbers are not supported.
• Cover sheet: include the recipient, department, reference number and your contact details.
• Use PDF for best quality: official forms, scans, and signed documents fax more clearly when converted to a clean PDF before upload.
• Check acceptance: confirm the submission deadline and any required follow-up. Delivery confirmation means the receiving fax system acknowledged receipt, not that a person has reviewed or accepted the document.
