Area Code 330

Area code 330 was created on March 9, 1996, as Ohio's first new area code since the North American Numbering Plan was established in 1995. It was formed by splitting the southeastern portion of area code 216, covering Akron, Canton, Youngstown, and Warren in northeastern Ohio. The split was approved by the Public Utilities Commission of Ohio (PUCO) in 1995, and the Ohio Supreme Court later upheld PUCO's authority over this relief plan in City of Parma v. PUCO (No. 97-2222). In October 1999, PUCO approved the 234 overlay for 330, making the 330/234 complex the first overlay in Ohio history and requiring mandatory 10-digit dialing by October 1, 2000.

Key milestones:

• 1947: AT&T created 86 original area codes. Ohio received four: 216 (Northeast), 419 (Northwest), 513 (Southwest), and 614 (Central). All of northeastern Ohio, including Akron, Canton, and Youngstown, was served by area code 216. (Source: TheDirectory.org)
• 1995: PUCO approved Ameritech's two-phase plan to split area code 216 due to number exhaustion. Phase 1 created 330 for the southern portion. The Ohio Supreme Court later confirmed this 1995 approval in City of Parma v. PUCO. (Source: FindLaw)
• March 9, 1996: Area code 330 went into service, covering 12+ counties in northeastern Ohio including Akron, Canton, Youngstown, and Warren. It was the 168th area code in service nationwide. (Source: Wikipedia)
• August 16, 1997: Phase 2 implemented. Area code 440 was created by splitting the remaining 216 territory (western and eastern suburbs of Cleveland), leaving 216 serving only Cleveland proper. (Source: TheDirectory.org)
• October 1999: PUCO approved the 234 overlay for area code 330, the first area code overlay in Ohio history. (Source: PUCO)
• November 1999: The FCC granted Ohio PUC delegated authority for number conservation measures under DA-99-2635 (CC Docket No. 96-98), enabling steps that delayed 234 activation. NANPA announced 234 as the overlay on November 5, 1999.
• February 21, 2000: NANPA issued Planning Letter PL-213 officially establishing the 234 overlay on 330. (Source: NANPA)
• April 1, 2000: Permissive 10-digit dialing began in the 330 area.
• October 1, 2000: Mandatory 10-digit dialing became required throughout the region.
• October 30, 2000: Area code 234 went into service as an overlay of 330. Area code 234 was originally planned as the relief code for Jacksonville, Florida, before being reassigned to Ohio. (Source: Wikipedia)

Ohio operated with four area codes from 1947 to 1996, a 49-year period with no new numbering resources. The creation of 330 ended that streak and initiated a series of relief measures, including the 440 split and the 234 overlay, that reshaped telephone numbering across northeastern Ohio.

Area code 330's regulatory history spans federal, state, and judicial jurisdictions across three key periods. In 1995, PUCO approved Ameritech's petition to split area code 216, creating 330 for northeastern Ohio, which the Ohio Supreme Court later validated in City of Parma v. PUCO (No. 97-2222). In 1999, the FCC granted Ohio delegated number conservation authority under DA-99-2635, and PUCO approved the 234 overlay, Ohio's first. NANPA Planning Letter PL-213 formalized the overlay in February 2000, with mandatory 10-digit dialing taking effect October 1, 2000. (Source: FCC)

The regulatory framework governing area code 330 involved three levels of authority: PUCO at the state level, the FCC at the federal level, and NANPA as the neutral administrator. The Ohio Supreme Court's 1999 ruling in City of Parma v. PUCO established that state commissions have broad authority over area code relief decisions, a precedent that continues to shape numbering policy in Ohio. (Source: Ohio Consumers' Counsel)
