Area code 445
Area code 445 is centred on Philadelphia, Pennsylvania. We hold 1,887 allocated blocks for it across 30 rate centres, split 62% mobile, 6% landline and 32% VoIP.
The other area codes laid over 445
Area code 445 does not have Philadelphia to itself. 2 other codes — 215, 267 — serve the same rate centres, laid over the same ground rather than dividing it. That is an overlay: a new code added when the old one ran out of numbers, covering the same streets. Two neighbours can hold different area codes, so the code says roughly when a number was issued rather than where it sits.
Each holds its own blocks and its own carrier mix, so a 445 number and a 215 number from the same street can report different line types. Filtering Philadelphia by area code needs all 3 of them.
445 is not confined to Philadelphia itself: its blocks sit across 30 rate centres, named in the table below.

Where 445 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Morrisvl and Phphsbzn39 are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

The largest holder, Verizon Wireless, has 25% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 445 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.

Common questions
Where is area code 445?
Area code 445 covers Philadelphia, Pennsylvania. It is not the only code there: 215, 267 are overlays on the same rate centres, so a Philadelphia, Pennsylvania number can start with any of them.
Is a 445 number a mobile or a landline?
It can be either, and the digits do not say which. North American mobile and landline numbers share the same ranges, so the answer comes from the carrier holding the block. In 445 the split runs 62% mobile, 6% landline and 32% VoIP, so mobile is the most likely single answer.
Which carriers hold 445 numbers?
The largest holders are Verizon Wireless, AT&T Wireless, Onvoy. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 445 numbers are there?
The code holds 1,887 allocated blocks in our copy of the numbering plan. A block is 1,000 or 10,000 consecutive numbers depending on how deeply it has been pooled, so 445 covers on the order of 1,887,000 possible numbers — most of which have never been issued to anyone.
