How Stripe delivers codes:Text (SMS)Authenticator appPasskey or security key

Stripe asks for phone numbers in two places: when you open the account, and for two-step authentication when you sign in to the Dashboard. If you run a US company or sell to US customers from abroad, a US number in the TripoSIM app covers both over Wi-Fi or mobile data. Every Stripe rule below is from Stripe Support.

Which phone numbers does a US Stripe account need?

Stripe says its financial partners require it to collect phone numbers for the business and the people on the account. When you open a Stripe account in the United States:

  • Business phone number: a valid and active US-based phone number. Individual and sole proprietor accounts do not need one. For a company formed through Stripe Atlas, it can be in any country.
  • Customer support number: a valid number in any country, and it can be the same as the business phone. Stripe shares it with card networks and shows it on cardholder statements, invoices and receipts.
  • Representative or owner number: a valid number in any country, except on individual and sole proprietor accounts, where it must be an active US-based number.

A TripoSIM US number is a +1 number in an app. Customers who see it on a receipt can call it, and you answer in the TripoSIM app or get a voicemail. Calls you make back use your 300 minutes a month to the US and Canada.

How do you turn on Stripe’s text codes?

  1. In the Stripe Dashboard, open your user profile (Personal details).
  2. Under Two-step authentication, click Add, then Add SMS.
  3. Enter your US number with +1 and click Confirm phone number.
  4. Enter the code from the TripoSIM app. Stripe says it can take a minute or two.
  5. Write down the backup code Stripe shows. It appears only once.

From then on, Stripe asks for a code when you sign in from a new device, and now and then to check the account is still secure. TripoSIM tested Stripe on October 3, 2026.

Which two-step method should you use?

Stripe lists its methods from most to least secure: passkeys, security keys, Touch ID or Windows Hello, authenticator apps, then text messages. It advises turning on two or more methods and avoiding SMS where you can. A sensible setup is a passkey or authenticator app as your main method, with your US number as a backup.

Sharing the account? Stripe says to invite each person as a team member, so everyone has their own login and two-step device. An administrator can require two-step for the whole team on the Team settings page.

What if you lose access?

  • Backup code: sign in, choose Sign in another way, then I don’t have any of these, and enter the backup code. This removes two-step so you can set it up again.
  • No backup code, account owner: send Stripe an account recovery request. Stripe says a decision may take a couple of business days, and the recovery link it emails must be used within 48 hours.
  • No backup code, team member: ask an account administrator to reset your two-step on the Team settings page.

Store the backup code offline, for example on paper in a safe place. Stripe advises against cloud storage or a plain-text note.

Keep the number too. If your TripoSIM plan ends, the number is kept 30 days on the yearly plan or 90 days on the monthly plan, then released. See number recycling and account security.

What if the code does not arrive?

  1. Wait up to 10 minutes, then request a new code. Stripe says delivery times vary and codes expire quickly.
  2. Check the TripoSIM app is online with notifications allowed.
  3. Changed numbers? On Personal details, click the … next to your phone and choose Update. Without the old number, use your backup code first.
  4. Still nothing: sign in with your backup code, then add an authenticator app as a second method. For the number itself, contact TripoSIM support.
