Official Colorado DORA electrical contractor and plumbing contractor registrations, licensed trades, AELS professional credentials, and discipline attached only by exact license prefix plus number. Colorado does not issue one statewide general-contractor license. This is not a ranking, recommendation, or Trust Score. Active is not recommended. A license row is not a unique company.

DORA statewide contractor-business evidence is Electrical Contractor (EC) and Plumbing Contractor (PC). General contracting, roofing, HVAC/mechanical, and many construction trades are primarily local. Absence from DORA EC/PC is not proof that a general contractor is unlicensed.
4,789
Active electrical contractor registrations
DORA prefix EC. Business-grain. Not unique companies. Not a general-contractor count.
3,147

DORA prefix PC. Business-grain. Do not add to EC as unique companies.
5,990
Contractor-relevant discipline observations
Rows with caseNumber on EC/PC/trade/AELS prefixes. One case may appear on more than one row. Not quality.
5,198
Distinct case numbers on those rows
Deduplicated caseNumber values. Still not a ranking or Trust Score.

DORA master license rows (all professions)
Not a contractor universe. Includes nurses, pharmacists, and other boards.
Public business identity is CO-DORA:{prefix}:{number}. This lookup covers EC and PC business registrations only. Individual electricians, plumbers, apprentices, architects, and engineers are not contractor-business profiles.

Model CO_DORA_SPECIALTY_NOT_GC. Primary regulator: Colorado Division of Professions and Occupations (DORA). Statewide electrical and plumbing contractor registration plus individual trade and AELS professional licenses. Does not issue a statewide general-contractor license. Source: CIM dataset 7s5z-vewr.
Identity CO-DORA:{licensePrefix}:{licenseNumber}. licenseNumber alone is not globally unique.
EC is a business registration (4,789 Active of 12,495 rows). PC is a business registration (3,147 Active of 5,415 rows). EC is not ME. PC is not MP. 784 normalized names hold more than one EC/PC credential.
Master/journeyman/residential electrician and plumber licenses are person-grain research evidence. They do not automatically create public person profiles. Apprentice records (APE, AP) are internal. Professional engineer, architect, land surveyor, and landscape architect licenses are not general contractors and are not construction businesses.

Contractor-relevant prefixes have 5,990 observation rows and 5,198 distinct case numbers. Attach only with exact licensePrefix + licenseNumber. Name-only is unsafe. A discipline row is not a unique case. A case is not a criminal conviction. No action found is not a clean record. The full DORA file has 59,624 flagged rows across all professions — do not call that a contractor discipline count.
