Finding Investigation Discovery on your Optimum setup doesn't have to be confusing. Whether you're navigating the traditional cable grid or looking for digital streaming alternatives, knowing where to find your favorite true crime programming saves you time.
Investigation Discovery, often called ID, remains a premier destination for docuseries, murder mysteries, and forensic investigations. If you subscribe to Optimum TV, your channel number depends on your specific regional lineup and whether you use legacy cable boxes or the newer Optimum Stream platform. This guide breaks down exact channel locations, package requirements, and digital viewing options so you can start watching right away.
Finding Investigation Discovery on Optimum Cable
Optimum organizes its channel lineups by region, meaning channel numbers can vary slightly depending on whether you live in New York, New Jersey, Connecticut, or parts of North Carolina. However, standard channel ranges usually place popular cable networks in predictable blocks.
For most Optimum subscribers, Investigation Discovery is broadcast in standard definition (SD) and high definition (HD).
- Standard Definition (SD): Often located around channel 124 or 198, depending on your local headend.
- High Definition (HD): Typically found on higher tier blocks, such as channel 675 or similar digital tiers.
To check your exact local channel number without flipping through hundreds of stations, press the Guide button on your Optimum remote and use the search feature. Type "Investigation Discovery" or "ID" to pinpoint the exact channel assigned to your zip code.
Package Availability and Tier Requirements
Not every cable package includes Investigation Discovery. If you can't find the network on your guide, your subscription tier might be the issue.
- Core and Select Packages: Basic tiers sometimes omit specialized cable networks or tuck them away into add-on sports and entertainment tiers.
- Preferred and Premier Packages: These higher-tier packages almost always include ID in their standard channel lineup.
- Custom TV Packages: If you built a custom channel pack, make sure entertainment networks were selected during your configuration.
If you recently changed your plan or moved to a new home within the Altice USA footprint, channel maps can take up to 24 hours to update on your set-top box. Restarting your cable box by unplugging the power cord for 30 seconds often forces a channel grid refresh.
Streaming Investigation Discovery Without Cable
If you've cut the cord or prefer watching on mobile devices, you aren't limited to a physical television box. Optimum subscribers can authenticate various streaming apps using their primary account login credentials.
Using the Optimum TV App
You can stream live television, including Investigation Discovery, using the official Optimum TV app available on iOS, Android, Amazon Fire TV, and Apple TV. As long as your mobile device or streaming stick is connected to your home Optimum internet network—or authenticated via your subscriber credentials—you can access your full channel lineup on the go.
Dedicated Network Apps and Max
Investigation Discovery is owned by Warner Bros. Discovery. This means you can log into the dedicated ID GO app using your Optimum username and password to watch on-demand episodes of shows like Homicide Hunter and Fear Thy Neighbor.
Additionally, much of the ID library streams on Max (formerly HBO Max) and discovery+. While these require separate subscriptions, they offer ad-free tiers and full season drops that traditional cable schedules don't provide.
Common Troubleshooting Steps for Missing Channels
Sometimes channels disappear from your guide or fail to load properly. Try these steps before calling customer support:
- Perform a Channel Scan: Go to your box settings menu and look for an option to rescan channels or update the program guide.
- Check Parental Controls: If certain networks are missing, a parental PIN might be blocking entertainment channels rated TV-14 or TV-MA.
- Verify Account Status: Past-due billing can result in partial service interruptions where basic channels work, but digital tiers are temporarily locked.
