Questions
Which carrier has 605-269 numbers?
The 605-269 block was assigned to Qwest according to the NANPA utilized-codes report. Individual numbers can be ported to another carrier, so a live check returns the carrier each number is on today.
Where are 605-269 numbers from?
The 605-269 prefix belongs to the Spearfish rate center in area code 605 (Sioux Falls, South Dakota). People keep their numbers when they move, so this is where the number was first assigned, not where the person is now.
Is a 605-269 number a cell phone?
The prefix alone cannot tell you. Numbers move between mobile, landline and VoIP carriers, so check each number: TrueSearch returns mobile, landline, VoIP or toll-free from live carrier data.
Does TrueSearch check Do Not Call lists?
No. TrueSearch does not check the National Do Not Call Registry, state DNC lists or litigator lists yet. Run those checks separately where they apply.
