See which state a telehealth visit comes from.

A clinician may only treat patients in the states they're licensed in. One lookup on a paid plan says which state or province a patient connects from, and whether a VPN, a proxy or a hosting server hides where they really are.

Care in the right state, and portals kept safe.

  • State licensure

    A clinician licensed in one state sees a patient connecting from another. Ask the patient to confirm where they are before the visit starts.

  • Patient portal log-ins

    Credential stuffing hits portals from proxy pools and hosting servers. Ask for a second factor when a log-in comes from one.

  • Prescription requests

    Refill requests for controlled medicines come through VPNs to hide where they're from. Hold them for a pharmacist when they do.

  • Appointment times

    Patients in another timezone miss appointments booked in yours. Show each slot in the patient's own time.

The state, and what might hide it.

The country, timezone, Tor and privacy relays answer with no key and no daily or monthly cap. The state, and VPN, proxy and hosting flags, come with every paid plan, and Pricing lists every field by plan.

  • location.country

  • is_vpn

Check at the moments licensure and safety depend on.

  1. 01

    At check-in

    Look up the patient's address when the visit starts and compare its state with the clinician's licenses. A VPN or a different state asks the patient to confirm where they are.

  2. 02

    At portal log-in

    Check each log-in's address before the session opens. A proxy or a hosting server asks for a second factor, and a home or mobile line goes straight through.

  3. 03

    When booking

    Read the timezone as the booking page loads, so every slot shows in the patient's own time. Keep their own choice if they set one.

On this page

Is an address enough to prove where a patient is?

No, and it shouldn't be the only check. It says where the connection is placed and whether a VPN or a proxy may hide it; ask the patient to confirm their location when the two disagree.
