How calls are dialed in 505

According to NANPA's dialing-plan data, local calls within 505 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 permissible at service provider discretion."

Phone companies in area code 505

47 carriers hold the 684 central office codes assigned in 505. Qwest Corporation has the most, with 184 (27%). 447 of the codes (65%) 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.

Local calling areas in 505

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 505 has codes in 34 rate centers. The table lists the rate centers with the most codes, with the matching Census place where the abbreviation could be matched.
