How to use this state page
Start with the state prefix and sample code list to understand how the registration family is structured. Then move to the exact code page if you already know the office number, or use the related guides if the question is about format, HSRP, or a state-specific rule change.
The yellow note on this page highlights the detail most likely to confuse users in that state, such as a legacy mark, a renamed prefix, or an office structure that does not map neatly to district boundaries.
