The EIN (Employer Identification Number) is your US business tax ID issued by the IRS. Most guides treat it as a formality. It's not. The EIN is what links your LLC to the US tax system, which is what gives your PayPal account its legal foundation.
When PayPal limits accounts for Pakistani-owned LLCs, the EIN is often the document that resolves it. Without a clean EIN, you have no real business identity to present during a review. Apply via Form SS-4 - as a non-resident, you'll submit by fax or use a registered agent service to handle it.
