How the edition is decided

The National Electrical Code is republished every three years, and each state decides when to adopt an edition. Building-code adoption and licensing examinations can change on different schedules. Confirm the edition for your exact exam and test date.

CortovaVoltPrep teaches NEC 2023 and NEC 2026 and switches between them with a toggle. These pages group recorded building-code adoption references last reviewed on September 6, 2026. A recorded adoption is not confirmation of the code edition on your licensing examination.

Local authorities having jurisdiction can enforce a different edition or local amendments than the state. Confirm your exam requirements before buying a code book. Use the free Exam Information Center for official state, local and territory sources, then choose your study edition at Start here.

Recorded adoption: NEC 2026

8 states

The source record lists NEC 2026 adoption. Confirm the current code and your exam edition separately.

Recorded adoption: NEC 2023

23 states

The source record lists NEC 2023 adoption. Confirm the current code and your exam edition separately.

Adoption not confirmed

For these 9 jurisdictions Cortova does not have the current adoption recorded in this directory, so it does not publish one. Ask your licensing board which edition it tests, then set that edition in the course. These pages are deliberately kept out of search results because they carry no state-specific fact worth ranking.
