If my small business has several offices and one is qualified as a ?principal office? that serves as the basis for a HUBZone designation, can all my offices claim HUBZone certification?

Yes, HUBZone is a status that applies to the entire business. This designation will remain in effect as long as any of the firm?s locations meet the test for and are certified as a “principal office” for HUBZone certification (assuming all other eligibility requirements are similarly maintained).
