What is an Instagram User ID?
Every Instagram account has a unique numeric User ID (also called PK or Primary Key) that is different from the visible username. While usernames can be changed at any time, the numeric ID remains constant throughout the life of the account.
Instagram User IDs are widely used by developers working with the Instagram API, social media managers automating workflows, marketers running influencer campaigns, and analysts tracking account metrics. The numeric ID is the most reliable way to reference an Instagram account programmatically.
