Everything the numbering plan knows, in one row.

Competitors return a status. We return the reasoning — so a human can overrule us when it matters.

One call · one credit
All fourteen fields come back together.

No tiered add-ons, no “carrier lookup” upsell. Every check returns the whole picture — in the API response and in your CSV export.

What this cannot tell you.

Most of this category advertises 99.9% accuracy. Here is the honest version.

It can tell you
Returned on every check, every plan
  • Whether the number is correctly formed for its country.
  • Whether the range is actually allocated, not just plausible.
  • Mobile, landline, VoIP, toll-free or premium rate.
  • The carrier the range was allocated to.
  • Country, region, timezone and today’s UTC offset.
It cannot tell you
No format check can
  • Whether the handset is switched on right now.
  • Whether the number was ported since it was allocated.
  • Whether a human still answers it.

You only truly know once a message or call is sent. Where the answer is genuinely ambiguous — in India and much of South East Asia, mobile versus landline often is — we return review instead of guessing.

Pay for answers, not seats.

Prepaid credits, and two ways to get them: commit to a plan for the lower rate, or buy any amount whenever you need it. The price per credit falls as the volume rises.

Questions

How is this different from a regex check?+
A regex says the shape looks plausible. We say whether the range is actually allocated by the country’s numbering authority, what kind of line it is, which carrier holds the range, and what timezone it sits in.
Do you send an SMS or place a call to verify?+
No. Nothing reaches the number, so nobody is disturbed and there is no per-message cost. That is also the limit: we cannot confirm a handset is switched on.
Why does a number come back as review instead of yes or no?+
Because in some numbering plans the mobile-versus-landline distinction is not available from static data. India and much of South East Asia included. A confident wrong answer costs you more than an uncertain one.
Will my CSV columns get rearranged?+
No. Your columns come back in their original order with ours appended after. Anything indexing your file by position keeps working.
What if a bulk job fails halfway?+
Jobs checkpoint as they run, so a restart resumes from the last completed chunk. You are not charged twice for rows already validated.
Do credits expire?+
No. Buy them, use them whenever. No monthly minimum and no seat pricing.
