Search Available Numbers
Search for available phone numbers before provisioning. Filter by area code or zip code, required capabilities (voice, SMS/MMS), and message type. Returns a paginated list of matching numbers. Run this step first to confirm number availability in your target area before calling the Number Provision endpoint.
What this does: Returns a paginated list of available area code and zip code combinations that have numbers matching your criteria. This tells you which area codes have available inventory before you commit to a provision call. Each result includes an NGP code and area code to use in POST /v1.0/numbers/provision.
Next steps:
- Provision a number from the results —
