Key Takeaways
Submit your station to directories like TuneIn, Radio Garden, iHeartRadio, Radio.net, Streema, Online Radio Box, Audacy, RadioBrowser, RadioFM, and Internet Radio.
Each directory has its own submission process and audience, so submitting to multiple directories increases listener reach.
iHeartRadio generally only accepts stations with FCC-issued call letters; internet-only stations are normally not eligible.
Most directories offer free submissions, with processing times ranging from days to weeks.
Submit to as many directories as possible — starting with larger ones — for the broadest audience reach.
Growing your online radio station's audience starts with being discoverable. While a great website and seamless listening options lay the foundation, submitting to internet radio directories is one of the most effective ways of reaching more listeners who are actively searching for new stations. Here's a curated list of the most influential directories to get listed on.
Directories matter more than ever because of where audiences now listen and how they find stations. In the US, 35% of the population age 12 and over, an estimated 101 million people, own a smart speaker (Edison Research, The Infinite Dial 2025), and those devices reach stations by querying aggregators rather than a manually typed URL. In the car, younger listeners increasingly skip the built-in tuner: US 13 to 24s spend 43% of their in-car audio time on a mobile device, roughly double the 21% all-ages average (Edison Research, Sound Data 2024). A directory listing is what puts your station inside the apps and assistants people already use.
Radio Cult Tip: Radio directories require your station's streaming URL during submission. If you're a Radio Cult station, you'll find your streaming URL in your station settings — ready to copy and paste into any directory submission form.
1. TuneIn
[02/10/2025] Update: TuneIn is now accepting new station submissions. US-based stations can submit their station via TuneIn On Air and Non-US stations can submit their station here.
TuneIn is one of the most popular internet radio directories with a massive global listenership. TuneIn is now accepting new station submissions — US-based stations can apply via TuneIn On Air, while non-US stations have a separate submission process (see the links above).
Aggregators like TuneIn also sit behind smart speakers and voice assistants. In the UK, listening through smart speakers and other online devices has climbed from 22% of all radio hours in Q1 2022 to 28% in Q1 2025, with smart speakers alone accounting for 26% of at-home listening (Ofcom, Audio listening in the UK 2025). Seven in ten (71%) voice-assistant users use it for radio as well as other audio, and 54% of those who listen to radio make their requests through a smart speaker (Ofcom, Audio listening in the UK 2025). A spoken request like "play my station" only reaches you if you're listed in the directories that power it.
2. Radio Garden
Radio Garden is one of our favourite radio directories. They're big supporters of community and independent radio and you can find some real pearls via them.
Additionally, Radio Garden has one of the most fun ways to find new radio stations via an interactive, globe-based interface. You can find new stations simply by spinning a virtual globe of the Earth.
You can submit your station to Radio Garden here.
It's also worth checking out the Community Radio Index, a directory dedicated to community and independent stations. Much like Radio Garden, it lets listeners discover stations from around the world by spinning a virtual globe.
3. iHeartRadio
iHeartRadio comes up a lot as a radio aggregator. However, not all stations are eligible to be submitted to iHeartRadio. Only stations with FCC issued call letters are currently being accepted. Online / internet-only radio stations are not able to be considered at this time.
You can submit your station to iHeart Radio here.
4. Radio.net
Radio.net, based in Germany, is one of the largest directories out there with 60,000+ radio stations on the platform (Radio.net).
You can submit your station via Radio.net's help centre form here.
5. Streema
Streema provides a large directory of global radio stations and allows users to browse by genre, country, and city. It also offers a social element, enabling listeners to connect with others around shared interests in music and radio.
You can submit your station to Streema here.
Every directory on this list asks for a stable streaming URL, so a reliable stream is the foundation of getting listed. RadioCult gives you a broadcast-ready stream and the URL to paste into each submission form.

8. RadioBrowser
RadioBrowser is a community-driven directory, like Wikipedia, with thousands of stations added by the community worldwide. It's open-source, and listeners can contribute by adding stations, making it a great resource for lesser-known, independent stations.

9. RadioFM
RadioFM has over 50,000 stations in its directory with over 100 million active listeners around the globe (RadioFM).
You can submit your station to RadioFM here.
10. Internet Radio
Internet Radio is a straightforward directory with a large collection of stations and genres, including a significant number of independent and niche broadcasts. It provides an easy way for broadcasters to list their stations, making it popular among indie content creators.
You can submit your station to Internet Radio here. Note that it supports Shoutcast and Icecast streams and asks you to add a reciprocal link back to internet-radio.com.
Directory listings are just one channel. Pair them with the other tactics in our guide to growing an online radio audience, and pick a plan that fits your station so you have the tools to keep every new listener you earn.

Do I need to pay to list my station on radio directories?
Most internet radio directories offer free submissions. Some directories may offer premium or featured listings for a fee, but a standard listing is typically free across all the directories listed above.
How long does it take for my station to appear after submitting?
It varies by directory. Some like RadioBrowser list stations almost immediately since they're community-driven, while others like TuneIn or iHeartRadio may take days or weeks to review and approve submissions.
Can I submit an internet-only station, or do I need an FM licence?
Most directories accept internet-only stations. The notable exception is iHeartRadio, which generally only accepts stations with FCC-issued call letters. All other directories on this list welcome online-only broadcasters.
Should I submit to every directory or just a few?
Submit to as many as possible. Each directory has its own audience and discovery features, so broader coverage means more chances for new listeners to find your station. Start with the largest directories (TuneIn, Radio Garden) and work your way down the list.
