Area code 215 is Philadelphia's original area code. The Pennsylvania PUC counts it among the state's four original area codes. A 1994 geographic split created 610 from the old 215 area, and two overlays, 267 and 445, now share Philadelphia's territory with 215.
Quick answer
- 215 is one of Pennsylvania's four original area codes and the code for Philadelphia, per the PUC.
- A 1994 split created 610 from the old 215 area. The PUC still lists 215 as Philadelphia's code.
- Overlays 267 (activated June 1999) and 445 (approved November 9, 2016) cover the same territory as 215. Existing numbers did not change.
- Local calls among 215, 267, and 445 use 10 digits, and calls to other area codes use 1 plus 10 digits (PUC, 2016).

How 215 became Philadelphia's code
- 1947: Area code 215 is opened. The FCC's utilization report lists its opening as January 1947. The PUC says Pennsylvania had only four area codes between 1940 and 1990: 412, 814, 717, and 215.
- 1994: The original 215 area in southeastern Pennsylvania is geographically split and area code 610 is introduced, according to the PUC's 2016 order. The sources we could open do not give the month.
- May 21, 1998: A PUC order directs that 215 and 610 each receive an overlay. The 215 area gets 267, and 610 gets 484.
- June 1999: The 267 overlay is activated and placed into service to relieve 215, according to the PUC's 2016 order. The FCC area code table lists 267 as opening in July 1999, one month later than the PUC order.
- August 5, 2016: NeuStar, as the neutral relief planner, petitions the PUC for an all-services distributed overlay of the 215/267 area. This is the docket P-2016-2560129 filing.
- November 9, 2016: The PUC grants the petition and approves the overlay. The new code is 445.
- March 3, 2018: The earliest date a new 445 number could be placed in service. The headline of a 2018 PUC press release says new numbers can begin service on March 3, 2018, and a carrier notice and a newspaper report give the same date. The FCC area code table lists 445 as opening in March 2018, which agrees on the month. We could not open the full press release from our network, so only its headline is used.
Where area code 215 is used
The PUC's area code page lists 215 as Philadelphia. It describes the six area codes of southeastern Pennsylvania (215, 267, 445, 484, 610, and 835) as covering "the Greater Philadelphia area and its surrounding counties." The page links a county and rate-center map for the 215/267/445 region, but the map could not be read as text.
Wikipedia, citing a PUC map, lists Philadelphia in full plus parts of Bucks, Montgomery, Lehigh, and Berks counties. A Philadelphia Inquirer report on 445 gives the same counties. Neither is a regulator source, so confirm a specific address with your phone provider before you assume its area code.
Why 215 needed relief
The PUC says Pennsylvania had four area codes until 1997 (814 in the northwest, 412 around Pittsburgh, 717 in the center, and 215 for Philadelphia). It says increased use of cell phones and other services made demand for additional telephone lines "exploded," which created the need for more area codes. The first change for 215 was the 1994 split that created 610.
In 1998 the PUC directed overlays for the 215 and 610 areas, and 267 followed for 215. In 2016 the industry projected exhaust for 215/267 in the second quarter of 2019 (April 2016 forecast). On September 9, 2016, NANPA moved that projection up to the second quarter of 2018, citing higher actual and forecast demand for codes.
The PUC found an overlay the least disruptive way to resolve the exhaust, because all existing customers keep their 215 or 267 numbers. The industry petition projected the new code would last about 24 years. Because an overlay was already in place, the PUC held no public input hearings.
Neighboring area codes in Pennsylvania
Philadelphia's own region is 215, 267, and 445. The table shows how other Pennsylvania codes relate to it, based on the PUC pages in this guide.
| Code | Where it applies | Relation to 215 |
|---|---|---|
| 215 | Philadelphia | Original code, opened 1947 |
| 267 | Same territory as 215 | Overlay, activated June 1999 |
| 445 | Same territory as 215 and 267 | Overlay, approved November 9, 2016 |
| 610 | Lehigh Valley and suburban Philadelphia | Split from 215 in 1994 |
| 484 | Same territory as 610 | Overlay on 610, ordered May 21, 1998 |
| 835 | Same territory as 610 and 484 | Overlay on 610/484; new 835 numbers no earlier than September 2, 2022 |
| 717 | Central Pennsylvania | Another of the four original codes |
Overlay codes that share 215's territory
An overlay adds a new area code to the same geographic area, so existing numbers do not change. Two overlay codes now serve Philadelphia's region alongside 215:
- 267 (activated June 1999): the first overlay on 215.
- 445 (approved November 9, 2016): the second overlay, an all-services distributed overlay of the 215/267 area. The PUC's 2016 order says an earlier 445 plan had been rescinded; Wikipedia dates that to 2003, which we could not confirm with the regulator.
Because the codes overlap, two neighbors on the same street can have different area codes. The area code does not show which building a number belongs to.
| Code | Added | Where it applies |
|---|---|---|
| 215 | 1947 | Philadelphia, original code |
| 267 | June 1999 | Overlay on 215 |
| 445 | Approved November 9, 2016 | Overlay on 215 and 267 |
Time zone and daylight saving time
Area code 215 uses Eastern Time. The tz database zone table lists America/New_York as "Eastern (most areas)." The federal rule in 49 CFR 71.4 puts the eastern zone east of the boundary described in 71.5, and that boundary runs through Michigan, Wisconsin, Indiana, Illinois, Kentucky, Tennessee, Georgia, Alabama, and Florida, not Pennsylvania.
NIST says daylight saving time starts at 2:00 a.m. on the second Sunday of March and ends at 2:00 a.m. on the first Sunday of November, under rules enacted by the Energy Policy Act of 2005. In 2026, NIST gives March 8 and November 1 as the change dates.
How to dial a 215 number
North American numbers have three parts: a country code, a three-digit area code, and a seven-digit local number. NANPA says the ITU assigned country code 1 to the NANP area. The PUC's 2016 order says local and toll calls within and between 215, 267, and 445 use 10 digits, so dial 215 plus the seven-digit number, and calls from those codes to other area codes use 1 plus 10 digits.
A carrier notice for the 445 overlay says you can still dial three digits to reach 911. Treat that as carrier guidance, and confirm any other rule with your provider.
Caller ID and scams with a 215 number
The FTC warns that "Scammers can make any name or number show up on your caller ID. That's called spoofing." Scammers can also match the first six digits of your own number. The FTC calls this neighbor spoofing.
- If you pick up and do not recognize the caller, the FTC advises that you hang up.
- Letting an unknown call go to voicemail is one option.
- The FTC says call blocking is your best defense against unwanted calls.
A 215 number shows the code that was assigned, not who is calling or where they are. Because 267 and 445 share the same territory, a 215 caller ID is not a reliable sign that the caller is in Philadelphia. The FTC pages we read do not say that 215 numbers in particular are targeted.
Business numbers in Philadelphia and nearby
215 is Philadelphia's original code, and 267 and 445 share its territory, so a business in the region may hold a number in any of the three. The PUC says an overlay does not change existing numbers, and new lines come from the overlay codes once the older codes run short.
Because the codes share territory, route calls by team or extension, not by area code. Ask your provider which code a new line gets, since that depends on its current inventory. 610, 484, and 835 are a separate region with its own overlays, so a business in the suburbs may be in either region.
Whether a specific 215 number can be assigned to your business depends on your phone provider and its current inventory. This guide does not make claims about availability.
Important: Confirm availability with your provider before you plan a campaign or print a number on materials.
Before you use a 215 number
- Confirm the number is available from your provider, and get its terms in writing.
- Ask who owns the number and whether it can be moved to another provider if you switch.
- Confirm which area code your line uses. 215, 267, and 445 all serve the Philadelphia region.
- Set 10-digit dialing for 215, 267, and 445 numbers before you go live, because the PUC's 2016 order says calls within and between these codes use 10 digits.
- Route calls by team or extension, because 215 and its overlays share one territory.
- Check each site's address. The PUC pages we could read do not give a county list, so confirm the address with your provider.
- Plan for caller ID. A 215 number does not prove who is calling, and neighbor spoofing copies the first six digits of your own number.
Frequently asked questions
Which area is the 215 area code for?
Area code 215 is Philadelphia's area code. The Pennsylvania Public Utility Commission (PUC) calls it the area code for Philadelphia and lists it with 267 and 445 as one region. The PUC says the six area codes of southeastern Pennsylvania (215, 267, 445, 484, 610, and 835) cover the Greater Philadelphia area and its surrounding counties. Secondary sources say the 215 region is Philadelphia plus parts of Bucks, Montgomery, Lehigh, and Berks counties; no PUC page we could open gives a county list.
Is area code 215 being split or replaced?
No split of 215 appears in the sources checked. Relief came from overlays: 267 (activated in June 1999, per the PUC) and 445 (approved by the PUC on November 9, 2016; the FCC area code table lists 445 as opening in March 2018, and the earliest date a 445 number could be placed in service was March 3, 2018, per the headline of a 2018 PUC press release). Existing 215 numbers keep their area code. The sources checked do not say when or how the region will get its next area code.
Does a 215 number mean the caller is in Philadelphia?
Not always. The FTC says scammers can make any name or number show up on caller ID, and neighbor spoofing matches the first six digits of your own number. Because 267 and 445 cover the same territory as 215, a local-looking number is not proof of who is calling or where they are.
Do I need to dial 10 digits for a 215 number?
Yes. The PUC's 2016 order says local and toll calls within and between 215, 267, and 445 use 10 digits (area code plus seven-digit number), and calls from those codes to other area codes use 1 plus 10 digits. The order says mandatory 10 or 1+10-digit dialing was already in place before 445 was added.
What is the difference between 215 and 610?
Area code 610 was created from 215 in 1994 when the original 215 area in southeastern Pennsylvania was geographically split, according to the PUC's 2016 order. The PUC describes 610, 484, and 835 as the region that serves the Lehigh Valley and suburban Philadelphia, while 215, 267, and 445 are the Philadelphia region.
