Dialing 253 numbers
According to NANPA's dialing-plan data, local calls within 253 are dialed as ten digits (area code plus number) and toll calls as 1 plus ten digits. Ten-digit local dialing means the area code is part of how customers save and recognize your number, so print it in full everywhere. NANPA's dialing-plan note for this code reads: "1+10-digit dialing permissible at service provider discretion"
Who holds 253 exchanges
27 carriers hold the 508 central office codes assigned in 253. Qwest Corporation has the most, with 141 (28%). 305 of the codes (60%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. Numbers can move between carriers through porting, so a code's holder tells you where the block started, not where every number lives now.
