ISO country code fields
ISO country code fields is standardized country and language code fields expressing where media content is available or what language it is in - ISO 3166-1 alpha-2 market/region codes (Spotify available_markets, YouTube regionCode) and ISO 639-1 stream language codes on Twitch. In Datadory's catalog of 1,744 datasets, Spotify Web API and YouTube Data API v3 are working examples.
What is ISO country code fields?
Standardized country and language code fields expressing where media content is available or what language it is in - ISO 3166-1 alpha-2 market/region codes (Spotify available_markets, YouTube regionCode) and ISO 639-1 stream language codes on Twitch.
In this catalog it appears concretely: - Spotify Web API — "market availability exposed per ISO 3166-1 alpha-2 country code (available_markets, now deprecated)". - YouTube Data API v3 — "regionCode parameter filters results by ISO 3166-1 alpha-2 country, and i18nRegions lists regions where content is localized". - Twitch Helix API — "stream language exposed as ISO 639-1 codes".
YouTube Data API v3 is the second reference point worth knowing: "regionCode parameter filters results by ISO 3166-1 alpha-2 country, and i18nRegions lists regions where content is localized". Reading the two together shows how much variation sits underneath one shared label.
Why does ISO country code fields matter when choosing a dataset?
A table is only as good as the column you actually need. If this field is absent, sparsely populated or defined inconsistently across rows, no amount of surrounding richness rescues the analysis, so it deserves its own line in your evaluation checklist.
The failure mode is concrete: a source can carry the ISO country code fields label while differing from what you need on exactly the dimension that matters — market availability exposed per ISO 3166-1 alpha-2 country code (available_markets, now deprecated). Comparing two sources on that line usually settles the choice faster than any feature matrix.
You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and Spotify Web API lets you inspect the real artifact before any budget is committed.
How do you evaluate ISO country code fields in a data source?
Treat every claim of this attribute as testable:
- Open Spotify Web API and confirm its record — "market availability exposed per ISO 3166-1 alpha-2 country code (available_markets, now deprecated)" — against the files you actually receive. 2. Open YouTube Data API v3 and confirm its record — "regionCode parameter filters results by ISO 3166-1 alpha-2 country, and i18nRegions lists regions where content is localized" — against the files you actually receive. 3.

Frequently asked questions
What is an example of ISO country code fields?
Spotify Web API is the clearest example in this catalog. Its record states: "market availability exposed per ISO 3166-1 alpha-2 country code (available_markets, now deprecated)". Across all 1,744 datasets Datadory averages a quality score of 7.81 out of 10, so a named example can be weighed rather than trusted blindly.
Is data described as "ISO country code fields" free to use?
Treat access and permission separately. 82.4% of the 1,744 datasets in this catalog are free to access, but 235 are freemium and 61 are paid outright, so confirm both the price and the license on the exact distribution before building on it.
How do I verify a source really provides ISO country code fields?
Open Spotify Web API next to YouTube Data API v3 and compare the promise with the download. Field definitions are verified for 1495 of 1,744 datasets (85.7%), which makes that check fast inside the catalog and manual outside it.
