If you freelance from outside the US, you may want a US number for Upwork or Fiverr. The TripoSIM US number receives verification codes (OTP SMS) from apps, and both platforms sent their codes to it in TripoSIM’s tests. Here is how to set it up, what both platforms say about location, and where a US number helps with clients.

Does the TripoSIM US number get Upwork and Fiverr codes?

Yes. TripoSIM tested 22 apps from October 3 to 18, 2026, and Upwork and Fiverr both sent their verification codes to its US numbers on October 3, 2026. The number receives codes from apps in general, so the list is examples, not a limit. Look up any other app in the app check tool.

How do you verify Upwork or Fiverr with the US number?

  1. Get the number from the plans page and open the TripoSIM app. Allow notifications so you see texts as they arrive.
  2. Add it as your phone number in Upwork or Fiverr. Pick United States (+1) and type the 10 digits, with no extra leading 1 or 0.
  3. Request the code once. It arrives as a text in the TripoSIM app. Wait a minute before asking again.
  4. Use the call option if the platform offers one. The number takes incoming calls and has voicemail.
  5. Enter the code and finish the check. Add an authenticator app as a second login method where the platform offers one.

If the code does not arrive, check the number format, make sure the app has internet, and contact TripoSIM support from the app.

Why must you register with your real country?

Both platforms check location and act on mismatches, whatever phone number you use:

  • Upwork allows a VPN only if “You’re still accurately representing your country of residence on your profile” and says a VPN is not for concealing “your true location” (Upwork Help: VPN). Mismatches can lead to “holds, verification requests, or even temporary suspensions”.
  • Upwork also says it “may restrict or permanently suspend your account if we cannot verify the information you provide” (Upwork Help: represent yourself authentically). Location checks can ask for a government ID, a utility bill or a financial statement, and the ID and profile address must be from the same country (Upwork Help: verify your location).
  • Fiverr’s community blog (July 2024) says “Misrepresenting your location for any reason is against our Terms of Service”. It also says travelling and working from another country does not trigger a flag, and asks you to tell Customer Success if you move (Fiverr Community).

A US phone number does not make you a US freelancer, and you should not use it to suggest you are one.

Where else does a US number help freelancers?

With your clients. Once a contract is running, some US clients prefer a quick call to a long message thread. Calling an overseas number can be costly or awkward for them, while a US number is an ordinary call. With the TripoSIM number you get:

  • A US +1 number your US clients can call like any other US number.
  • 300 outgoing minutes a month to US and Canadian numbers, through the app over Wi-Fi or mobile data.
  • Voicemail when you are asleep in another time zone.
  • Texts from US and Canadian senders, with no sending or replying.

Before moving any client contact off-platform, check that platform’s rules on communication and payments, and keep payments on the platform. Our freelancer use case page and the guide to a second number for freelancers cover setup, working hours and voicemail greetings. To look up other apps, use the app check tool.

Bottom line

You can verify Upwork and Fiverr with the TripoSIM US number: both sent their codes to it in TripoSIM’s tests on October 3, 2026. Keep your profile set to your real country, and use the number for US clients who want to call you too. Our explainer on what a VoIP number is covers the number type, and the plans page has both plans.
