An **advertiser** in AdCrunch is one ad account on one provider — for example, one Meta ad account, or one TikTok ad account. Advertisers are the unit of authorization (you grant AdCrunch access at the ad-account level) and the unit of scoping (every campaign, ad, and insight in AdCrunch belongs to exactly one advertiser).

## Identifiers

Every advertiser has a stable AdCrunch ID prefixed `acc_`. The provider's own identifier is preserved as a soft pointer.
