Licensing boards adopt a specific code cycle, and it is not always the newest one. Check which edition your state or jurisdiction tests from before ordering.

See our electrician exam guides by state for the electrical trades. For plumbing and HVAC, or if you are still not sure, contact us with your state and licence level and we will point you to the right book.

Yes. We tab books by hand before they ship — tabs on every major article so you can find what you need under pressure.

Allow up to a week for a tabbed book to be prepared and shipped, since the work is done by hand. If you have an exam date coming up, order early or contact us and we will tell you what is realistic.

Every book we sell is an official published edition. We are a supplier, not a publisher — we are not affiliated with the NFPA, the ICC, or IAPMO.

We carry the official Spanish-language editions where they are published — the real translations, not summaries. Check the Libros en español collection, or contact us and we will tell you whether a Spanish edition exists for this code.

We ship within the United States. Allow up to 10 business days for delivery after your order is processed; most orders arrive sooner. Tabbed orders are prepared by hand, so allow up to a week before they ship.

Ordered the wrong edition? Contact us within 7 days of delivery and we will exchange it, as long as the book is unused and unopened. Damaged or incorrect items are on us. Full terms are in our refund policy.
