What is what area code is 267?

Area code 267 is a telephone area code in the North American Numbering Plan (NANP) for the southeastern part of Pennsylvania, specifically the city of <a href="https://www.wikiwhat.page/kavramlar/Philadelphia">Philadelphia</a> and its immediate surrounding suburbs in Bucks, Montgomery, and Delaware counties. It overlays area code <a href="https://www.wikiwhat.page/kavramlar/215">215</a>. Area code 267 was introduced in 1999 as an overlay to relieve the exhaustion of available phone numbers in area code 215. The overlay means that both area codes serve the same geographic region, and ten-digit dialing (area code + seven-digit phone number) is required for all calls.
