Micronesia phone number format

How do you format a Micronesia phone number?

Write a Micronesia phone number with the country code +691. A mobile looks like 350 1234 inside Micronesia and +691 350 1234 from abroad. Mobiles have 7 digits after the country code, and the E.164 form is +6913501234. A format check confirms the digits fit the numbering plan, not that the number is in service.

How to write a Micronesia number in E.164

  1. Remove spaces, dashes, dots and brackets so only digits are left.
  2. Micronesia has no trunk prefix, so keep every digit of the national number.
  3. Put +691 in front. The result has 7 digits after the country code for a mobile.

So 350 1234 becomes +6913501234. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.

Mobile or landline?

In Google’s numbering-plan data, many Micronesia ranges are listed as “fixed line or mobile”, so the digits alone can’t always say whether a number takes texts. A live carrier lookup asks the network which kind of line serves the number now. More in mobile vs landline lookup.

Mobile, landline and special number ranges in Micronesia

A Micronesia mobile number starts with 3100, 3120, 3130, 3201–3209, 3301–3309, 3501–3509, 3602, 3701–3709, 3804, 3905, 820, 92–97 after +691. Every valid number of each type below starts with one of the digit groups shown. A number that starts the right way can still be unassigned: the groups say what a range is for, not that a number is connected.

Common questions

What is the country code for Micronesia?
The country calling code for Micronesia is +691. When you call Micronesia from abroad, dial your international prefix (or +) followed by 691 and the number.
How many digits is a Micronesia phone number?

How do I write a Micronesia number in international format?

Can you tell if a Micronesia number is a mobile?
Not always from the digits. In Google's numbering-plan data many Micronesia ranges are listed as "fixed line or mobile", so the number alone doesn't settle it. A live carrier lookup asks the network which kind of line serves the number today.
Does a valid format mean a Micronesia number is in service?
No. A valid format means the digits fit a range Micronesia's numbering plan allocates. It cannot tell whether the number is connected today or who carries it, because numbers are reassigned and ported. A live carrier lookup reports the current carrier and line type, but even that does not prove someone answers.
