All contractors must include their CCB license number on everything from business cards to site signs. License numbers are required on: 
  • Business cards
  • Written bids
  • Building-related contracts
  • Advertising, including telephone book, newspaper, radio and television ads.
  • Business letterhead stationery
  • Business signs at construction sites
  • Written inspection reports
  • Business vehicles with signage
Think of your CCB license number as a marketing tool and a way for potential customers to confirm that you are a licensed professional. Potential customers who see your license number on your business cards, bids, etc. can quickly confirm your license status on our website or by calling 503-378-4621. 
Many homeowners call the CCB to check on contractors but  don’t know the owner’s name or the correct spelling. If we can’t find your license number, you may lose work because people think you’re unlicensed.  
The number should include “CCB” and then your license number (for example, CCB #123456). You can also include the words “Licensed and bonded”. Violating OAR 812-003-0120 by failing to provide a CCB number can bring a fine of up to $400. 
Promotional items
  • CCB numbers are encouraged but are not required on promotional items where it is not practical to include them such as pens, pencils, bug deflectors, refrigerator magnets, etc.
  • Numbers are also not required on clothing or uniforms for sports teams sponsored by construction businesses.
