Know which of your old phone numbers are still alive.

Save the US and Canada numbers you used to own. Number Watch checks carrier records and tells you whether each one is still active, looks disconnected, or has been reassigned to someone else.

Live status checks

Each number is looked up against carrier records, with the result stored in your private history.

Honest signals

We surface what carriers actually tell us — and we're upfront when something's just "unknown".

Automatic re-checks

Pick daily or weekly. We'll quietly re-check in the background and flag any changes.
