How the 463 Area Code Was Created clock-face timeline infographic on pale ice-blue background with 713-style blue palette showing a large bright-blue bordered clock circle with bold 463 at center and blue clock hands five white milestone cards connected by dashed blue lines to nodes around the clock ring reading 1947 Indiana assigned area code 317 then 1990s-2000s Mobile growth depletes 317 then Early 2010s Exhaustion forecast confirmed then 2016 IURC approves 463 overlay then Sept 2 2016 463 numbers go live semi-transparent blue decorative circles in corners

Indiana received area code 317 in 1947 as part of the original North American Numbering Plan. For decades, 317 served Indianapolis and the surrounding counties without issue — a single code was more than sufficient for the region's calling needs.

The situation changed dramatically through the 1990s and 2000s. Rapid population growth in the Indianapolis metro, particularly in Hamilton County, combined with the explosion of mobile phones, pagers, fax lines, and broadband connections, consumed available 317 number combinations far faster than original projections anticipated. By the early 2010s, forecasts confirmed that 317 would reach exhaustion within a few years.

Rather than splitting the region geographically — a disruptive approach that would have forced many 317 customers to change their numbers — Indiana regulators chose an overlay solution.

The Indiana Utility Regulatory Commission (IURC) approved the 463 overlay plan, coordinated mandatory 10-digit dialing across the region, and set the activation date. From September 2, 2016, all new telephone lines in the metro area became eligible for 463 numbers while every existing 317 holder kept their number unchanged.

Key milestones:

  • 1947 — Indiana assigned area code 317 under the original North American Numbering Plan
  • 1990s–2000s — Mobile and broadband adoption accelerates 317 number depletion
  • Early 2010s — Forecasts confirm 317 approaching exhaustion
  • 2016 — IURC approves 463 as an all-services overlay for 317
  • 2 сентября 2016 г. — 463 numbers begin active assignment in the Indianapolis metro

Правила набора номера 463

Because 463 overlays 317 across the same geographic territory, ten-digit dialing is mandatory for every call in the region — including calls between two neighbors on the same Indianapolis street.

Calling fromFormat to use
Within the 463/317 area463-XXX-XXXX (10 digits mandatory)
Elsewhere in the US or Canada1-463-XXX-XXXX
International+1 463 XXX XXXX

Ten-digit dialing became a requirement across the Indianapolis metro before 463's official launch to prepare residents for the new overlay. Any contacts saved using only the seven-digit local number must be updated to include the full area code — calls without it will not connect.

Indianapolis has grown into one of the Midwest's most significant economic centers. A 463 number connects your business directly to a metro area of more than 2.1 million residents across industries that include sports, life sciences, logistics, and one of the country's most active convention calendars.

Key reasons to choose a 463 area code number:

  • Local credibility — Indianapolis residents answer calls from familiar local prefixes at significantly higher rates than unknown out-of-state numbers
  • Sports and events economy — Indianapolis hosts the Indy 500, Big Ten championship games, the NCAA's national headquarters, and major conventions at the Indiana Convention Center year-round
  • Life sciences cluster — Home to Eli Lilly's global headquarters and a network of biotech and pharmaceutical companies that drive intensive B2B activity across the region
  • Logistics corridor — The intersection of I-65, I-70, and I-74, plus Indianapolis International Airport's FedEx hub, makes this one of the country's premier supply chain markets
  • Virtual reach — Just as businesses across Oregon rely on the 458 area code to reach Pacific Northwest customers without a physical office, a 463 number lets you connect with Indianapolis's market from any location and device

Как защититься от мошеннических звонков 463

Watch Out for 463 Scam Calls shield security infographic on pale ice-blue background with 713-style blue palette showing a bright-blue shield badge with 463 at top connected to five alternating white and light-blue horizontal rows each with a red triangle warning icon bold dark navy scam name and description for IRS Impersonation Social Security Fraud Utility Shutoff Threats University Scholarship Scams and Prize and Lottery Fraud with reportfraud.ftc.gov text at bottom and semi-transparent blue decorative circles in corners

As 463 numbers have become more widespread, fraudsters have begun spoofing them to appear local and trustworthy. Neighbour spoofing — displaying a 463 number that matches your own area code prefix — is particularly effective because both 317 and 463 are recognized as Indianapolis numbers.

Common 463 scam types to watch for:

  • IRS impersonation — Callers claim unpaid taxes and threaten immediate arrest without payment
  • Social Security fraud — Automated messages state your SSN has been suspended and demand verification
  • Utility shutoff threats — Callers posing as Indianapolis Power & Light or CenterPoint Energy demand immediate payment to avoid service disconnection
  • University scholarship scams — Fake financial aid calls targeting IUPUI, Butler University, and Purdue Polytechnic students
  • Prize and lottery fraud — Callers say you have won a prize but require an upfront fee before you can claim it

How to protect yourself:

  • Let unknown 463 calls go to voicemail before returning them
  • Never share financial details or Social Security information with an inbound caller you did not initiate
  • Verify any organization through the number listed on its official website
  • Report suspected 463 scam calls to the FTC at reportfraud.ftc.gov

Legitimate government agencies and established businesses will never demand immediate payment by gift card, wire transfer, or cryptocurrency during an unsolicited call.

Часто задаваемые вопросы

What is the 463 area code?

The 463 area code is a North American telephone area code assigned to Indianapolis and the surrounding central Indiana metropolitan area. It was activated on September 2, 2016, as an all-services overlay for area code 317, meaning both codes cover the same geographic territory simultaneously.

Where is the 463 area code located?

Area code 463 is located in central Indiana, serving Indianapolis and its suburban counties including Hamilton (Carmel, Fishers), Hendricks (Avon, Plainfield), Johnson (Greenwood), Boone (Zionsville), Morgan, and Hancock. The entire coverage area falls within the Eastern Time Zone.

Is 463 the same area as 317?

Yes. The 463 area code covers the exact same geographic territory as the 317 area code. Both codes serve Indianapolis and the surrounding metro counties simultaneously, which is why the arrangement is called an overlay — no geographic boundary separates them.

Why does Indianapolis have two area codes?

Indianapolis was assigned a second area code because the 317 prefix was running out of available number combinations. Rapid population growth — especially in Hamilton County — along with mobile phone adoption and broadband demand depleted the 317 supply faster than early planners anticipated. Regulators chose the 463 overlay in 2016 to extend capacity without forcing existing 317 holders to change their numbers.

What time zone is area code 463 in?

Area code 463 is in the Eastern Time Zone. Indianapolis observes Eastern Standard Time (UTC−5) in winter and Eastern Daylight Time (UTC−4) during daylight saving time. Indiana follows a single time zone statewide, so all 463 numbers observe Eastern Time regardless of their specific location within the coverage area.

Is a 463 number a cell phone or landline?

A 463 number can be a cell phone, a landline, or a VoIP number. Because 463 is an overlay code, it is assigned to all types of new telephone subscriptions across the Indianapolis metro regardless of technology. There is no way to determine whether a 463 number is mobile or landline from the area code alone.

Do I need to dial 10 digits when calling a 463 number from a 317 number?

Yes. Because 463 and 317 are overlapping codes sharing the same geography, all calls within the region require ten-digit dialing. You must include the full area code before the seven-digit number even when calling a local Indianapolis neighbor — calls using only seven digits will not connect.

Can I get a 463 number for a business located outside Indiana?

Yes. Virtual phone service providers offer 463 area code numbers to businesses and individuals regardless of physical location. A virtual 463 number lets you establish a local Indianapolis presence and forward calls to any device anywhere in the world, with no Indiana address required.
