It sounds like Airbnb mistakenly categorized your account as a business instead of an individual host. Since support hasn’t been helpful, try these steps:
Double-Check Your Account Settings
Remove Any Business-Related Details
If you entered a company name, VAT number, or business address anywhere, try removing them in your Profile & Listing settings.
Escalate the Issue
Contact Airbnb again, but this time request to speak with a senior support representative.
Explain that you accidentally selected a business account and need it switched to an individual host account.
Keep emphasizing that you are not a business and do not have business documentation.
I know this is frustrating, especially as a new host, but hopefully, one of these steps helps!
