# Trade Cert Hub

> Free, state-by-state licensing reference for U.S. skilled trades — electricians, plumbers, HVAC contractors, and general contractors. Every page lists continuing-education (CE) hours, renewal fees, bond and insurance requirements, exam details, reciprocity, and links the official state licensing board with a last-verified date.

Trade Cert Hub covers 4 trades across all 50 states (246 license profiles). Data is sourced from official state licensing boards and cited on every page. The site is free and supported by affiliate links to CE-course and bond providers, which never change the underlying data or its ordering. Content is general information, not legal advice — confirm with the official board before relying on it.
