POST api.tracenow.io/phone

Know if a number is real — and reachable.

Send a phone number in any format. Get formatting, country, carrier and line type, VoIP and burner flags, plus a live network check that tells you whether the number is actually active right now.

What you can do with it

  1. 1

    Validate before you send an SMS

    Confirm a number is well-formed, valid for its country and currently active — so you stop burning OTP spend on dead or fake numbers.

  2. 2

    Flag VoIP and burner numbers

    Catch disposable and VoIP numbers used in fraud and bonus abuse, with a daily-refreshed burner-prefix list behind a single flag.

  3. 3

    Confirm live reachability

    A live network lookup returns whether the number is connected, its carrier, and porting and roaming status — the strongest "real person" signal on a phone.

  4. 4

    Normalize and enrich at scale

    E.164, local and international formatting plus country and region metadata clean and standardize numbers across your whole dataset.
