Delaware area code
Delaware has one area code: 302.
- 302 has been in service since 1947. Delaware is one of 11 states served by a single area code.
- The registry lists no overlay for 302.
- A local call within 302 is usually dialed with 10 digits, the predominant pattern NANPA records for it.
- On the 07/30/2026 registry file, no new code is assigned to Delaware and no relief planning has begun for it.
This is public numbering-plan data from NANPA, reproduced as its registry records it. It is not ours, and an area code says where a number was assigned, not where the person holding it lives.

The Delaware area code in the registry
As the NANPA registry file dated 07/30/2026 lists it. An overlay code serves the same area as the code it was laid over.
| Area code | In service since | Overlaid with | Local calls dialed with |
|---|---|---|---|
| 302 | 1947 | None | 10 digits |
Two codes are shown as overlaid only where each code's own registry row lists the other. The registry's rows occasionally disagree, and where they do the pairing is left out rather than guessed. The dialing column is the predominant pattern NANPA records for a local call within the same code.
