Pennsylvania area codes

Pennsylvania uses 15 area codes. The oldest is 215, in service since 1947; the newest is 835, from 2022. Across them 8,263 of 11,790 possible number blocks are allocated, 70.1% of capacity. 267, 484, 717, 814, 215, 724, 570, 610 and 412 are at or past 95%, which is why new numbers there come from overlays rather than the original code. Verizon holds 33.8% of the 8,263 assigned blocks across the state, ahead of AT&T at 12.6%; a further 14.1% sits with CLEC and VoIP holders outside the national carriers. In the 33 days to 30 October 2026, FTC complaints named a Pennsylvania caller ID 8,292 times – 3.6% of all complaints in the window, most often 610 with 1,030 (36th of 422 nationally). NANPA records 1,387 rate centers across the state's codes, and local calls take all ten digits.

Block share is share of allocated number blocks, not of subscribers. Complaint counts cover 28 Sep – 30 Oct 2026 and reflect spoofed caller IDs as much as real calls.

How full Pennsylvania’s codes are

A code holds at most 786 blocks of 10,000 numbers each. When a code fills up, the administrator does not reclaim numbers – it adds an overlay, and from then on new numbers in the same area come from the new code.

70.1% of capacity allocated – 8,263 of 11,790 blocks
9 codes at or past 95% – effectively closed to new numbers
3,527 blocks still unallocated across the state

Who holds the number blocks

Counted from every assigned block in the state: 8,263 blocks, each with the holder NANPA recorded for it. Percentages are measured, not estimated.

“Other CLEC / VoIP” is not one company: it is every holder outside the national carriers counted together, which is what resellers and app-based numbers look like in the records. This is allocation, not subscribers.

Spam complaints naming Pennsylvania codes

FTC Do Not Call complaints where the caller ID shown was a Pennsylvania number, 28 Sep – 30 Oct 2026 (33 days). Caller IDs on spam calls are routinely faked, so these are complaints about the code, not calls proven to come from it.

Frequently asked about Pennsylvania area codes

How many area codes does Pennsylvania have?

15 in service. They are 215, 223, 267, 272, 412, 445, 484, 570, 582, 610, 717, 724, 814, 835 and 878.

What is the oldest area code in Pennsylvania?

215, in service since 1947. Every later code in the state was split off from or overlaid on an existing one.

What is the newest area code in Pennsylvania?

835, from 2022, overlaying 484.

Is Pennsylvania running out of numbers?

267, 484, 717, 814, 215, 724, 570, 610 and 412 are at or past 95% of capacity, but NANPA has not opened relief planning for them, so no new code is announced.

What time zone is Pennsylvania in?

Eastern time.

Which Pennsylvania area code gets the most spam complaints?

610 – 1,030 FTC complaints in the 33 days to 30 October 2026, 36th of 422 codes nationally. Those are complaints about the caller ID shown, and spam callers routinely fake a local-looking number, so this says the code is imitated often, not that the calls come from there.

Which carrier holds the most Pennsylvania numbers?

Verizon, with 33.8% of the 8,263 blocks assigned across Pennsylvania, ahead of Other CLEC / VoIP at 14.1%. This is allocation of blocks by the numbering administrator, not a count of subscribers – people keep their numbers when they switch carriers.

Do you have to dial 10 digits in Pennsylvania?

Yes. Every code in the state is in an overlay or ten-digit dialing area, so a local call needs the area code too. Dialing seven digits reaches a recording, not a wrong number.
