Wangiri check: is this missed call a scam?

Purpose

Check whether the calling code of an international missed call is a known origin of one-ring callback scams (wangiri), and what to do.

Requirements

Anyone can read these guides, no account needed. Some tools require Pro, as indicated in each guide.

Got a missed call from abroad? Type the number or just its calling code. We tell you whether that code is a known origin of “one ring” scams that want you to call back an expensive number.

Read the available fields alongside their limitations. An empty result does not prove safety or identify a person.

Known origin of missed-call scams: Calls from this calling code keep appearing in wangiri campaigns. Do not call back: the call is charged as an expensive international call.

Caribbean area code used in one-ring scams: This +1 area code looks like a domestic North American number, but calling back is billed as an international call. It is a classic one-ring scam origin.

Satellite or global network: These codes have some of the highest per-minute rates. Do not call back a missed call from one of them.

A number from this edition’s country: It is not an international call, so it is not a wangiri pattern. If it seems suspicious, look the number up to see reports from other people.

Not on the list: This calling code is not among the usual wangiri origins. That does not make the call safe: if you don’t know anyone there, don’t call back.

Unknown calling code: No allocated calling code starts with those digits. Check the number: it may be spoofed or incomplete.

Limitations

Indicative information from published numbering plans. It describes the type of number, never the person or company behind it.

Troubleshooting

If the input is invalid, check its format and country. Retry connection errors; respect the waiting period when a limit is reached.

Enter a valid phone number or prefix.

Use with the API

Whether the calling code is on the wangiri (one-ring callback scam) list, Caribbean NANP, satellite, domestic or not listed.

Send the JSON body to the tool's own route, or to POST /v2/tools with the tool field added. Both routes return the same result.
