Certified Welder (CW) Quickcheck

Free Online CW Verification Service
Please enter a CW number below. This number can be found on a wallet card produced by the welder. The search will return the certification number, a name, and an expiration date for that individual.

Enter Certification number
Note: AWS strongly suggests that the welder’s identity be verified with a government issued photo identification card, such as a driver’s license.

How to interpret the CW number:

  • The first four digits of the CW number are the year and month of original certification. For example, 9603xxxW means that the Welder was certified in March of 1996.
  • The next three digits of the number are unique and the last letter of the CW number indicates that the certification is for a welder.
