Beginning on November 1, 2013, hard copy, mail-in apprentice registration applications will no longer be available. Contractors will be directed to use our online registration system to register apprentices when hired or remove their registration upon separation. You can find instructions for using the online system here.
NOTE: Our new system requires that all contractors have a correct FEIN (Tax ID number) in our database. If an attempt to register results in a “No match found” error message, please DO NOT register a new account, contact us at DORA_DPO_OnlineLicenses@state.co.us or 303-894-2421 so that we may ensure information accuracy in our system.
Registration Expiration Grace Period for New Applicants. All new applicants who are issued a plumbing contractor registration within 120 days of the upcoming expiration date will be issued a registration with the subsequent expiration date.
Registration Renewal Information. All Plumbing Contractor registrations expire on February 28 in odd-numbered years and must be renewed to continue practicing.
If you did not find the information you need, send an e-mail to the Division of Professions and Occupations.
