Are Airtable Record IDs unique across Tables? Across Bases?

I’m curious to know if record IDs like reciw1K6rcYbpRN0o are unique for a table, unique for a base, or unique across bases for an organization.

Hi Roman,

They are currently globally unique, but you shouldn’t count on this being the case in the future. We may change them to only be unique within a base, so it would be best to always store the base ID (begins with app) alongside the record ID in external systems.

Thanks Kasra!

Is it correct then that record IDs are never reused within a base, even after records are deleted?

That’s generally true, but we can’t guarantee that outside of your plan’s data retention period.
