NANPA groups these codes in shared numbering complexes: 202 / 771. Members can serve overlapping areas; being in the same complex does not necessarily mean identical geographic boundaries.

Open the individual area code to check its local dialing rule. For a phone lookup, enter +1 followed by the three-digit area code and the seven-digit number. A state or area code alone is not enough to look up a particular number.

No. An area code describes a number’s assigned region. People can keep numbers after moving, use them while traveling, or place internet-based calls. Caller ID can also be spoofed, so the code does not confirm the caller’s location or identity.
