The number you verified in June can belong to someone else by September. Numbers get ported, disconnected and reissued every day, so a carrier lookup is only as good as the date behind it.
Ours pulls carrier and line-type data updated daily from FCC and carrier sources, not a snapshot from whenever the contract was signed.
1 question for whoever sells you carrier or portability data: when was this last updated? If the answer comes back in months, you are dialing history.
Has a ported number ever cost you a campaign, or did you only find out from the bounce report?
