Telephone number data.

The data comes from the network we run.

It is a database — ours. The difference is what feeds it: we have run a voice network since 2003, so carrier, line type, rate center and routing come out of the same systems that carry the calls, not from a file licensed third-hand.

Why people look a number up.

Three questions, one lookup.

Can I text it?

You cannot text a landline. Screening a list on line type before a send stops you paying for messages that cannot arrive, and keeps the delivery rate carriers judge your 10DLC campaigns on.

Is this signup real?

A VoIP number, or one ported last week, proves nothing on its own. It is still a signal worth having while the account is being created rather than after something goes wrong.

Where should this call go?

Route on the carrier that owns a number now, not the one that issued it. Terminating on-network traffic as though it were off-network means paying someone else to carry your own calls.

We hold the data for all of these — they simply do not have a product wrapped around them yet. If one of them is what you actually need, say so and we will tell you honestly how far off it is.

The volume, the format, and whether it runs against a list or inside a call path. We'll tell you straight whether we're the right fit.
