The 614-356 prefix belongs to area code 614 and is anchored to the Dublin rate center (OH). In NANP terms, the prefix — or NXX — determines the rate center a number is billed against.

Dublin is part of the Columbus, OH Metropolitan Statistical Area. For routing purposes it sits in LATA 324. Numbers here keep Eastern time.

Code-holder of record: OHIO BELL TEL CO (OCN 9321), assigned April 13, 2001. The prefix is pooled: its ten thousands-blocks can be shared among several carriers, so different 614-356 numbers may be served by different companies.

Caller ID showing 614-356 is not proof the call came from Dublin: spoofing and porting both detach numbers from their origin. To verify a caller, hang up and dial the organization's published number, and report suspicious calls to the FTC.
