You can use a P.O. Box for your mailing address in registration. However, for the physical address of your entity, requires a street address. This distinction is important because while the mailing address can be a P.O. Box, allowing for flexibility in where you receive business correspondence, the physical address must accurately reflect your entity’s actual physical location for verification and legal purposes.

When registering or updating your information in, ensure that you provide both types of addresses correctly to comply with the registration requirements and to facilitate any necessary contact or verification by federal agencies.

If you need assistance with navigating what address to use, a Certified Registration Specialist (CRS) can help with the registration process. Call the Help Desk at (888) 646-9998 Mon-Fri 9am-5pm EST to find out more about how USBRI can help you get started with government contracting.
