Hark Pro SMS Verification — Receive Your OTP Code
Hark Pro is an AI assistant that works inside your email and logins, and the number on it receives its texts. Signival gives you a temporary non-VoIP number to receive the OTP. Pay in Naira or crypto.
Hark Pro is the AI assistant from Hark Labs, released on web, iOS and Android on 6 October 2026. Reports say you can sign up with Google, Apple or an email address, and Hark may ask you to verify a mobile number, which it uses to text you. It sends a one-time password (OTP) by SMS, a temporary code you enter to continue. If you would rather not use your personal SIM, Signival gives you a temporary non-VoIP phone number that receives the Hark SMS verification code and shows it in your dashboard.
We could not reach a Hark help page on phone verification, so this guide sticks to what Hark’s Terms of Service say and what users report. Two things stand out. The number is tied to texts: Hark’s terms say adding one means you get recurring automated messages, and you must tell Hark if it changes. And Hark Pro acts inside your inbox and logins, so it is an account worth protecting. This guide covers both, how to receive a Hark OTP with Signival, and what to do when a rented number expires.
Why Hark Pro Asks for a Mobile Number
Hark’s Terms of Service say that by adding your mobile number to your account, you agree to receive recurring automated text messages from Hark. These include replies to your requests, task updates and account notifications.
The terms also say you must tell Hark promptly if you change or deactivate your mobile number, and that carriers are not liable for delayed or undelivered messages. You can stop texts only by removing the number in your account settings or by telling your agent.
Hark Pro is built to act for you. Reviews describe it connecting to your email and signing in to sites, and the terms make you responsible for activity through your account and say you must keep your credentials secure and not share them. Users also report phone checks appearing during sign-up or in promotional flows, so read what the screen asks for.
When Hark Pro May Ask for a Phone Number
Signing up or adding a number
Reports say sign-up works with Google, Apple or an email address. When Hark asks you to verify a mobile number, it sends a code by SMS.
Receiving texts from your agent
Once a number is on your account, Hark’s terms say it texts you replies, task updates and account notices.
Removing or changing the number
The terms say to remove the number in your account settings or tell your agent, and to tell Hark promptly if the number changes.

Get an available number for Hark Pro, receive the SMS verification code, and complete your activation through your Signival dashboard.
Can a Temporary Number Receive Your Hark Pro OTP?
An OTP number is a temporary phone number, sometimes called a virtual number, that receives text messages without a SIM in your phone. For Hark Pro it can receive the verification code by SMS.
We could not find a rule about VoIP or virtual numbers in the Hark pages we reached. Signival numbers are sourced from mobile operators rather than internet-based VoIP lines, but Hark runs its own checks, so there is no guarantee.
Hark’s terms say carriers are not liable for delayed or undelivered messages, so a slow code is not unusual. A Signival activation is short, though, so if no SMS arrives within the window, cancel and try another number.
A rented number expires, and Hark texts that number with task updates and notices. Once you are verified, remove the number in your account settings or move to one you keep, and use a Google, Apple or email sign-in you control. Hark Pro can log in to sites for you, so do not make a rented number the only thing standing between you and the account.

Tips for Receiving Your Hark Pro SMS Code
- Use the official Hark Pro listing. Search for Hark Pro from Hark Labs on the store, or use hark.com. Do not install a ‘Hark’ app from a link someone sent you. Several unrelated products share the name.
- Try the web version if the app is missing. Reports say the app has not reached every country’s store yet, and that the web version is the same assistant on the same account.
- Keep a login you control. Reports list Google, Apple and email as sign-in options. A login you control keeps working after a rented number expires.
- Remove the number once you are done with it. Hark’s terms say you stop texts by removing the number in settings. Do that before the rented number is reassigned.
- Never share the code. Hark’s terms tell you not to share your credentials. A code is only ever for you to type into Hark.
If Your Hark Pro OTP Code Does Not Arrive or Is Rejected
The SMS does not arrive
Check the country code and digits, wait through the activation window and request the code once. Hark’s terms note that carriers can delay or fail to deliver messages. If nothing arrives within 5 minutes, cancel for a refund.
Hark says the number cannot be used
Check the country code and digits. If they are right, Hark may not accept the number, so cancel and try one from another country.
The code arrives but is not accepted
Codes expire quickly. Type it in as soon as it appears, and request a new one only if the first has expired.
Texts keep going to an old number
Remove the number in your Hark account settings or tell your agent, and tell Hark promptly if the number has changed or been deactivated.
You think someone else has access to your account
Hark’s terms say to notify support@hark.com promptly about suspected unauthorized access. Change your sign-in credentials too.
