Phone numbers beginning 835 are registered to the Allentown area of Pennsylvania (Eastern time zone). The code entered service on September 2, 2022. The same territory is also served by its overlay codes (484/610/835 complex). Keep in mind the code identifies where the number was registered; the person calling may be elsewhere.

The code currently holds 96 working prefixes, held by 16 different carriers. Of these, 96 are pooled prefixes shared by multiple carriers. Numbers are anchored to 29 rate centers — billing localities that fix where each prefix belongs.

If a 835 call asks for money or personal data, treat the displayed number as unverified: hang up and reach the organization through its published number. Numbering data locates numbers, not callers.

The code was carved out of 484 (2022).

The current NANPA exhaust forecast for the 484/610/835 complex is 3Q 2050.

Local calls inside 835 are dialed 10D; 1+10 digit dialing for all hnpa and fnpa calls permissible at service provider discretion..

FAQ

Will 835 run out of numbers?

NANPA's current forecast projects exhaust in 3Q 2050 — decades of capacity remain.

Why am I getting spam calls from 835 numbers?

Scammers spoof recognizable area codes so calls look local or familiar. A displayed 835 number does not prove the call originated there — see our guide to spotting spoofed calls.

Where is a 835 number from?

835 is assigned to Allentown and surrounding areas of Pennsylvania in the Eastern time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
