In Zenefits, your Legal Address must be an actual physical location and cannot be a PO Box or UPS Store. Under CIP rule (31 C.F.R. § 103. 121), which implements §326 of the USA PATRIOT Act, banks and other financial institutions (FIs) must collect certain information. Zenefits moves money for payroll and as such is considered to be a financial institution (FI). This requires us to obtain a Physical Legal Address, as PO Boxes/UPS Store Boxes are not verifiable. PO Boxes and UPS Store Boxes are considered mailing addresses.
