What is a NAC number? C-NAC vs D-NAC, explained

What is a NAC number?

Last verified July 2026

A NAC, or Notice of Assignment of Counsel, is how CPCS ties you to a case. You get one every time you are assigned a client, and it is the number your time bills against. A few things about it are worth knowing.

One NAC per case

Every time CPCS assigns you to a client, that case gets its own Notice of Assignment of Counsel. One client with three open cases has three NACs. Check each one for accuracy when it arrives and keep a copy in the file (Assigned Counsel Manual, Chapter 5).

A C-NAC and a D-NAC are not the same

There are two kinds, and they behave differently in eBill.

(eBill 2.0 User Manual, Section 3.)

Why a C-NAC bill sits "pending"

When you bill against a C-NAC before CPCS has the official assignment on file, the bill shows as pending. That is normal and it is deliberate, so you can still hit your billing deadlines while the paperwork catches up. Once CPCS has the assignment, the status changes from Pending to On File (eBill 2.0 User Manual, Section 3.1). A D-NAC cannot be added as pending. If one does not show up, call the eBill helpdesk.

One NAC can carry more than one docket

A single NAC can cover several docket numbers. eBill wants the full docket number for each, entered as it appears on the complaint. If there is no docket yet, you enter "No Docket" (eBill 2.0 User Manual, Section 3.2).

How Plani helps

When you connect Plani to eBill, it reads your NAC list and matches your clients to the right NAC, so your time files against the correct case. If a client has more than one NAC and Plani cannot tell which is right, it asks you before it files anything.
