NANPA lists Onvoy as the company holding the 681-210 block, one of 83 681 prefixes it holds. That is who was given the numbers, not who serves each one today: since number portability, any 681-210 number can move to another carrier and change from landline to mobile or VoIP.
Onvoy is one of the companies that commonly supply numbers to VoIP and texting apps, so numbers in this block are more likely to be VoIP lines. Only a per-number check confirms it.
A TrueSearch check returns, for every number:
- ✓Valid or dead. Disconnected and unassigned numbers are flagged before your dialer or SMS tool reaches them.
- ✓Mobile, landline or VoIP. Know which 681-210 numbers can take a text.
- ✓Current carrier. Which may or may not still be Onvoy.

Questions
Which carrier has 681-210 numbers?
The 681-210 block was assigned to Onvoy 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 681-210 numbers from?
The 681-210 prefix belongs to the Bluefield rate center in area code 681 (Charleston, West Virginia). People keep their numbers when they move, so this is where the number was first assigned, not where the person is now.
Is a 681-210 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.
