A Pacific nation on the radio dial
.fm is the ccTLD of the Federated States of Micronesia, spread across hundreds of islands in the western Pacific. Thanks to FM radio, it became the natural ending for stations, podcasts and music services — Last.fm is the best-known example. Its sibling in spirit is .am, Armenia's code, which AM radio brands use the same way.
If you're naming a show or a station, .fm says "audio" faster than any tagline.
Good for
- Radio stations and internet radio
- Podcasts and audio networks
- Music discovery and streaming services
Watch out for
- Higher prices than most generic TLDs
- Means "FM radio" only to listeners who still remember the dial
.fm by the numbers
.fm is the internet country code for Micronesia. It's one of Micronesia's ccTLDs, the two-letter domains reserved for countries and territories.
.fm has a second life online. Because of what the letters suggest, it's picked up a following for FM radio, podcasts and audio, beyond Micronesia's borders. Legally it remains Micronesia's ccTLD.
A little context on Micronesia: the capital is Palikir, the main language is English and the international dialing code is +691.
IANA lists FSM Telecommunications Corporation as the manager of .fm, with an address in Micronesia (Federated States of). The registry's website is https://www.dot.fm. ccTLD managers set their own policies — who can register, which second-level names exist, pricing to registrars — so those rules differ from country to country.
On the technical side, .fm is served by 6 authoritative name servers, every one of them reachable over IPv6. It is also DNSSEC-signed: the root zone carries a DS record for .fm, which lets validating resolvers check its answers cryptographically. Registration data is published over RDAP and WHOIS (the WHOIS server is whois.nic.fm).
.fm FAQ
What country is .fm?
The Federated States of Micronesia, a Pacific nation of more than 600 islands. "FM" is its ISO 3166-1 code.
What does .fm mean?
Officially, .fm is simply the ISO 3166-1 code for Micronesia. Online, it's also used for FM radio, podcasts and audio — a "domain hack" that uses the letters for what they spell.
What does .fm mean in an email address?
Only that the sender's domain is registered under .fm. Because .fm is also used for FM radio, podcasts and audio, it doesn't necessarily mean the person is in Micronesia.
Who owns the .fm domain?
IANA lists FSM Telecommunications Corporation as the manager of .fm: it runs the registry and sets the rules for Micronesia's ccTLD. Individual .fm names belong to whoever registers them.
Can I register a .fm domain from the US?
It depends on FSM Telecommunications Corporation's policy. Some ccTLDs are open to anyone in the world, while others require a local address, company or trademark. Check the registry (https://www.dot.fm) or an accredited registrar before you buy.
Is .fm DNSSEC-signed?
Yes. The root zone has a DS record for .fm, so DNSSEC validation works all the way down from the root.
How do I look up who owns a .fm domain?
Query the registry's registration data service: the WHOIS server is whois.nic.fm, and RDAP lookups go to https://rdap.centralnic.com/fm/. Many registrants use privacy services, so personal details may be hidden.
