Multiple Facebook ad accounts: Meta's limits and setup

Originally published on proxymint.

Meta allows several ad accounts in one business portfolio. The real limits, roles, agency access and spend controls, and where a steady login IP helps a team.

TL;DR

• Meta allows multiple ad accounts inside a business portfolio. One person can manage up to 25 ad accounts, and each ad account can have up to 25 people, per Meta's help pages checked September 2026.
• A new portfolio starts with a creation limit of 1. The limit grows after a confirmed payment and with spend history, closed accounts still count, and full-control holders see the current number under Business info.
• Multiple ad accounts are normal, multiple identities are not. Meta asks for one personal account per person and may restrict business assets tied to a disabled account or created to evade a removal.
• Agencies work in the client's account without owning it. Request to share, partner access and the on-behalf-of relationship keep ownership, billing and history with the client.
• Most teams need no proxy. A steady login IP only helps distributed staff keep a consistent login history, and it never raises a limit or lifts a restriction.

Key takeaways

• Check your own creation limit before planning accounts. Business Settings, Business info, "Ad account creation limit", visible to people with full control.
• Give every person their own access, never a shared login. Use full control for 2 owners, partial access with task access for buyers and analysts, and finance for billing.
• Set an account spending limit on every ad account. Ads stop at whichever of the Meta daily spending limit, the account spending limit and the daily budget is lowest.
• Run Meta's security checklist quarterly. Remove people who no longer need access, close ad accounts nobody uses, and turn on peer approval.
• Add one static ISP IP per person only for distributed teams. One per person, never one per ad account. A restricted account goes to Account Quality.
