Guam number not seven digits long?

Sometimes, the number you want to call may already be written out including the area code and/or +1 country code. For example:

  • +1 671 555 0012
  • (671) 555-0012
  • 671-555-0012

In such cases, just make sure the last seven digits (the local number) are prefixed with 00 1 671. All the examples above would be dialled from the UK as: 00 1 671 555 0012.
