Podcast GUID and OPML: what actually moves between apps
Last updated: June 2026
Podcast GUIDs and stable feed identifiers can help apps recognize shows when feeds move. The Podcast App supports OPML import/export and RSS-based listening; subscriptions can move with OPML, while history, progress, and GUID matching depend on what the source app and feed provide.
Your Identity, Not Theirs
Switch apps without rebuilding every subscription
OPML is the practical bridge most listeners can use today. Export your subscriptions from an app that supports OPML, then import that file into The Podcast App.
Stable feed identity reduces matching problems
Podcast GUIDs and episode GUIDs help identify shows and episodes when publishers provide them, but they do not automatically transfer private app state such as history, favorites, or downloads.
How Podcast GUID Works in The Podcast App
Read the feed data that is available
The app works from podcast RSS feeds and directory metadata. When stable identifiers are present, they can improve matching; when they are missing, feed URLs and directory records are still part of the fallback path.
Use OPML for the portable part
OPML usually carries subscriptions, not playback history or queue state. That makes it a good switching format, but not a complete backup of every app-specific detail.
Episode identity depends on publisher metadata
Episode GUIDs are publisher-provided RSS fields. They are useful when available, but progress and history still depend on how each app stores and exports its own data.
Your Questions, Answered
What is a podcast GUID?
A podcast GUID is a stable identifier published in a podcast RSS feed through the Podcasting 2.0 namespace. It helps apps and directories recognize a show even when feed URLs or hosting providers change.
Does OPML transfer my listening history?
Usually no. OPML is mainly a subscription-list format. It can move the shows you follow into The Podcast App, but playback history, progress, favorites, downloads, and queue state depend on what the previous app can export.
Does every podcast publish stable GUID metadata?
No. Many shows include episode GUIDs, and some include Podcasting 2.0 podcast:guid metadata, but support varies by publisher and hosting platform. The Podcast App should work with the feed data that is available.
Understanding Podcast GUID: The Foundation of an Open Podcast Ecosystem
For most of podcasting's history, a show's RSS feed URL was the only identifier that mattered. Subscription apps stored that URL, matched it against their databases, and assumed it would remain stable forever. In practice, it rarely did. Podcasters switched hosting platforms, rebranded their shows, consolidated feeds, or moved from one domain to another — and every time they did, listeners lost their subscriptions, their progress, and their history. The problem was structural: the industry had adopted a mutable, infrastructure-specific URL as a permanent identity, and no app could do anything about it when that URL changed.
Podcasting 2.0 defines podcast:guid as a stable show identifier in the podcast namespace. In practice, listeners benefit most when publishers include stable identifiers and apps keep OPML import/export available as the everyday migration path.
The Podcast App is built around RSS-based podcast listening and OPML portability. Stable identifiers such as podcast:guid and episode GUIDs are useful when publishers and directories provide them, but the app does not promise perfect cross-app history recovery from data that most OPML exports do not include.
