Ohio Contractor License Search (OCILB)

Search and verify Ohio contractor licenses straight from the official Ohio Construction Industry Licensing Board (OCILB) eLicense registry — the state's system of record for licensed specialty contractors.

Covers all five OCILB-licensed trades plus training agencies:

• EL — Electrical Contractors
• HV — HVAC Contractors
• HY — Hydronics Contractors
• PL — Plumbing Contractors
• RE — Refrigeration Contractors
• TA — Training Agencies

What you get

Each record includes:

Field	Description
name	Licensee name
credentialNumber	License number (e.g. EL.47712)
licenseType	Trade (Electrical, HVAC, Plumbing, …)
status	ACTIVE / INACTIVE / etc.
issueDate / expirationDate	Current license period
company	Company the license is registered under
address	Company public address of record
credentials[]	All credentials held by the contact (many contractors hold EL+HV+PL+RE under one number)
renewalRequirements[]	CE completion status + estimated renewal amount due
detailUrl	Link to the official detail page

Use cases

• License verification — confirm a contractor's license is active before hiring or writing a policy
• Lead generation — build lists of active electrical/HVAC/plumbing contractors in Ohio
• Compliance monitoring — track expirations and status changes across a contractor network
• Insurance & lending — validate trade licensing during underwriting

Input

Search by any combination of:

• lastName, firstName, maidenName — licensee name
• licenseNumber — number without the trade prefix (e.g. 47712 for EL.47712)
• credentialTypes — restrict to trades: ["EL", "HV", "PL"]; leave empty for all
• includeDetails — fetch each result's detail page (address, dates, company, all credentials, CE info); default true
• maxResults — cap the number of records (default 100, 0 = unlimited)

Example

{
    "credentialTypes": ["EL"],
    "lastName": "Smith",
    "includeDetails": true,
    "maxResults": 50
}

Notes

• Data comes directly from the official state registry at elicense4.com.ohio.gov — no third-party databases.
• Results are paginated 12 per page server-side; the actor handles pagination automatically.
• With includeDetails enabled the actor makes one extra request per result (throttled politely).
