Delaware Reverse Phone Lookup

Identify Phone Number Location Using Delaware Area Codes

To identify the location of an Delaware phone number, you need to understand the North American Numbering Plan (NANP) structure that all Delaware numbers follow: +1 NPA NXX XXXX.

• +1 - Country code indicating the United States
• NPA - The area code reveals the geographic region where the number was originally assigned
• NXX - Central office code that locates the specific neighborhood and identifies the service provider
• XXXX - Subscriber number identifies the individual phone line within that local exchange

The area code (NPA) is your key to determining location. By matching the three-digit area code to Delaware's regional assignments, you can identify which part of the state the phone number originates from. Each area code corresponds to specific cities and counties throughout Delaware, making it possible to narrow down the caller's general location.

Here's a complete list of Delaware area codes with major cities:

Delaware Phone Numbers

Delaware has approximately 1.5 million active phone numbers. Mobile phones account for the majority with 1.18 million users. Traditional landlines are declining, with 54,000 connections statewide. Internet phone services account for about 290,000 numbers.

The dominance of cell phones means that searching a Delaware phone number will likely return a mobile result. The decline of landlines suggests that tracing newer numbers might be more challenging compared to older landline numbers with more readily available public information.
