What is a Facebook UID & Why You Need It

Every Facebook profile, page, and group is assigned a unique numeric identifier (UID). While users see custom usernames, Facebook's Graph API and internal systems use these permanent numerical IDs for all operations.

API Integration

Developers need numeric UIDs for Facebook Graph API queries. Custom usernames don't work with API endpoints.

Custom Audiences

Facebook Ads Manager requires numeric IDs for precise custom audiences and targeted campaigns.
