Check if a phone number
has been ported

One API call returns a ported flag, the original carrier, and the network serving the number today — resolved from national portability registries.

Hundreds of millions of numbers have moved between networks under number portability. Once a number is ported, everything keyed to its original carrier — SMS routing, pricing, fraud rules — quietly points at the wrong network. And a recently ported number is a classic SIM-swap signal worth checking before you trust an account change. This page's lookup is part of Current Carrier Lookup, Veriphone's live-registry product.

The ported flag, in context

Add mode=current to a verify call. If the number has moved, ported is true and both carriers are in the response. 

{
  "phone": "+14155552671",
  "carrier": "T-Mobile USA, Inc.",
  "current_carrier": "Verizon Wireless",
  "ported": true
}

Example response, abbreviated — the full standard validation fields are always included.

10 credits per lookup on any paid plan or credit pack — from $2.00 per 1,000. If the current carrier can't be resolved, you pay the standard 1-credit rate: no result, no surcharge. See pricing.

FAQ

Frequently Asked Questions

Yes. The lookup reads national portability registries — nothing is sent to the phone, and the owner is never contacted or identified. You learn which network holds the number, not who owns it.

No — it tells you whether the number is currently served by a different network than the one it was assigned to, and which network that is. Porting dates aren't part of the registry data we return.

230+ countries and territories — see the live coverage list. Where resolution isn't available, you get the standard validation result at the standard rate.
