    Choose a country

    Select the country whose number you need for your Hardblock verification. Each country shows live availability and the current price.

Why use a temporary number for Hardblock

A disposable non-VoIP number is the safest way to verify Hardblock: you avoid SIM-swap exposure, keep your primary number off Hardblock's servers, and can spin up additional accounts for business, testing or travel. Free public numbers are usually already burned — a dedicated number from VoIPStore is fresh and high-deliverability.

Hardblock in United States — FAQ

Can I receive Hardblock SMS with a United States non-VoIP number?

Yes — our United States (+1) numbers are real, non-VoIP mobile lines that Hardblock accepts for SMS verification. They have high deliverability and are not on the blocked VoIP lists Hardblock screens for.

How long does the United States number stay active?

Long enough to receive your Hardblock code — usually up to ~20 minutes. It's a one-time number for the verification, not a recurring rental.

What happens if the Hardblock code never arrives?

The order expires and the United States number is auto-refunded to your balance. You only ever pay for numbers that successfully deliver a code.

Do I need to be in United States to use the number?

No. You can order a United States number from anywhere in the world and receive the Hardblock SMS in your VoIPStore dashboard.
