Numverify alternatives
If you are weighing up a move off Numverify, here are the options that actually exist, what to check before you commit, and the cases where staying put is the right call.
Common reasons to shop around
- You need more than format validation: line type from real numbering-plan data, spam reputation, or fraud signals.
- You want email and IP checks on the same balance instead of a separate subscription for each.
- You need documented data provenance for a compliance review.
What you can move to
Veriastra
details →Numbering-plan validation plus spam reputation from published complaint records, and the same credits work across email, IP and domain.
Numverify
Fine for straightforward format and country validation at low volume, and priced accordingly.
libphonenumber
The open library underneath most format validation. Free, self-hosted, no rate limit.
Three things worth checking
What is actually behind the endpoint
Format validation is an open library. If that is all a service does, you are paying for hosting and a rate limiter.
Spam and complaint data
Reputation is only as good as its source. Ask whether it comes from published regulator complaints or from an unnamed pool.
Rate limits at your peak
Cheap tiers throttle. Check the ceiling against your busiest hour, not your monthly average.
What the switch actually involves
- 01
Work out what you are buying first
At their top tier they are cheaper per call — $129.99 for 250,000, read 6 Aug 2026 — and that price buys format and carrier.
If those two fields at scale are genuinely the whole requirement, stay: you would be paying us for signals you never read.
People move when the requirement grows a third field, because that is the point where their price stops being the low one.
- 02
The endpoint
POST /api/lookup-phone. The response is a superset: everything they return, plus rate centre and OCN, complaint history from the FTC and FCC, and whether the number sits on your own suppression list.
- 03
The field that changes name
Their `line_type` becomes `type`, `carrier` stays `carrier`, and `valid` stays `valid`. The rest is additive, so an existing integration keeps working on the fields it already reads.
- 04
The reason people actually move
Not the fields — the decision. /api/dial-check answers "should this number be called" in one request instead of leaving you to write the thresholds yourself.
- 05
Run both for a week
They and we both read numbering-plan data, so agreement should be very high. Look at the disagreements: they are usually recently allocated blocks, and whichever refreshed most recently wins.
When to buy something else
For a hobby project doing a few hundred format checks a month, a free tier somewhere will serve you better than any paid plan — including ours. The arithmetic flips the day the checks decide something: a wrong line type in production costs more than the whole plan.
