In auto insurance, NB stands for Named Built, which refers to an agreed value that you and your insurer set for a specific vehicle when you carry comprehensive and collision coverage. This prearranged amount is used as the basis for paying losses, helping avoid disputes over actual cash value at the time of a claim. The practice is most common for classic, modified, or newer vehicles whose market value may fluctuate or whose replacement characteristics differ from standard trims. Below are key details to clarify how NB works in practice.

How Named Built Agreed Value Works
When you choose NB coverage, you and the insurer settle on a fixed value for the car. After that, this amount becomes the reference point for loss settlements within policy limits and endorsements. Typically, the carrier will verify the vehicle's specifications, condition, and documentation before finalizing the figure. Because the value is named in the policy, it can streamline claims and reduce negotiation at the time of loss. Below is a concise comparison of common valuation approaches in auto insurance.
| Attribute | Verified Detail | Source Type |
|---|---|---|
| NB (Named Built) | Agreed vehicle value set with insurer for comprehensive and collision coverage | Industry practice and policy terms |
| ACV (Actual Cash Value) | Market value at loss time, accounting for depreciation | Standard claims methodology |
| Stated Value | Policyholder-provided value within insurer's limits; may differ from NB | Underwriting and policy forms |
| Agreed Value | Mutually accepted value, often used for classic or specialty autos; NB is one form | Underwriting guidelines |
When NB Agreed Value Is Used
Insurers commonly apply NB agreements for vehicles where market valuation is complex or where standard ACV approaches could create dissatisfaction. Situations include classic car policies, where originality and restoration matter more than age; modified vehicles with added equipment; and new models in the first model years before residual values stabilize. In these cases, specifying NB helps align expectations and ensures that coverage reflects the car's agreed worth rather than a fluctuating market estimate.
NB Versus Other Common Auto Insurance Terms
Several abbreviations appear in auto policies, and it is important to distinguish NB from similar terms. Below is a short list that contrasts NB with related concepts to reduce confusion.
- NB (Named Built): Agreed value specified for a particular vehicle in the policy
- ACV (Actual Cash Value): Depreciated market value at the time of loss
- AV (Agreed Value): General term for a mutually accepted loss settlement amount; NB is one implementation
- RC (Actual Cash Rate) or SSC (Stated Safety Coverage): Sometimes used for specific endorsements, not the same as NB
Implications for Premiums and Endorsements
Choosing NB coverage can affect premiums because the insurer is committing to a specific payout level. Premiums may be higher than with standard ACV policies, reflecting the reduced depreciation and the insurer's exposure to the named value. Policyholders should review endorsements that define how NB is calculated, whether it includes accessories, and how it interacts with deductibles and limits. Regular updates may be needed if modifications are made or if the vehicle's condition changes, ensuring the coverage remains aligned with the NB amount.
