Errors during Meta's embedded signup fall into four stages. Find your stage, then the message you saw.

1. Business account creation

• "You have reached the limit for Businesses you can create" — use an existing business portfolio instead of creating a new one.
• "Your Facebook account is too new" — Meta blocks new accounts from creating portfolios; wait a few hours or use an established account.
• "You're no longer allowed to use Facebook Products to advertise" / disabled payment account — the Facebook account is flagged; use a different admin's account in good standing.

2. WhatsApp Business Account creation

• "User does not have permission" — you need admin rights on the business portfolio.
• "Limited number of WhatsApp Business Accounts before verification" — unverified businesses can create only one WABA; verify your business to add more.
• "We can't verify the Facebook Business Account" — the portfolio failed policy checks; check the email Meta sent, fix, and resubmit or use an already-verified portfolio.

3. Phone setup

• "This number is registered to an existing WhatsApp account" — delete the consumer-app account on it (or use Coexistence for a Business App number), wait ~3 minutes, retry.
• "Your verified name violates guidelines" — fix per the display name rules.

4. Phone verification (OTP)

• "Your phone number doesn't appear to be valid" — check international format; IVR-only numbers aren't supported.
• "You have guessed/requested too many times" — rate-limited; wait up to 12 hours, then resume the flow with the same number.
