Sign up with your mobile number

The Mobile tab of the sign-up page: your name, your mobile number and a 6-digit code on WhatsApp. No email or password needed.

The sign-up page (/signup) has two tabs, Mobile and Email, under Continue with Google and the other one-click buttons, which work whichever tab is open. Mobile is the default: you sign up with your mobile number and a 6-digit code that OmniBrand sends you on WhatsApp, with no email address and no password. Email is the form with Your name, Email and Password, described in Sign up: creating your OmniBrand account. The page remembers the tab you used last in this browser. The Mobile tab is shown only while OmniBrand can send codes on WhatsApp; when it cannot, the page shows the email form only.

Before you start

  • You need WhatsApp on the number. The code arrives as a WhatsApp message from OmniBrand's own number, with the code and a button to copy it. There is no text message (SMS) option.
  • The number must be a mobile number. A landline is refused.
  • Everything else is as with email sign-up: no card is asked, nothing is charged, and a paid plan picked on the pricing page starts the 14-day Pro trial.

Step by step

  1. Open the sign-up page and click Mobile at the top (it is already selected the first time).
  2. Fill in Your name.
  3. In Mobile number, the button on the left shows a flag and a country code, for example +966. It starts on the country you are visiting from. When that cannot be told, it starts on the country of your browser's language, for example +1 (United States) for English or +20 (Egypt) for Arabic. Check it before you type your number. To change it, click it, type a country name or a code in Search for a country or code, and click the country.
  4. Type your number in the box next to it, as you dial it in that country (for example 050 123 4567), or with + and the country code (for example +966 50 123 4567).
  5. Tick Send me help and updates on WhatsApp if you want tips and news from OmniBrand on WhatsApp. It is not ticked by default, and the account works the same without it.
  6. Click Send code. The page then says "Enter the 6-digit code we sent on WhatsApp to (your number)."
  7. Type the 6 digits in Code. The sixth digit sends it by itself; you can also click Sign up (or Start 14-day free trial when you chose a paid plan). The code works for 10 minutes.
  8. Your account is created and you are signed in. The setup wizard opens, as after an email sign-up.

Above the form, tick the box "I agree to the Terms and Privacy Policy"; that is your consent, as on the Email tab.

Buttons on the code step

  • Resend code: a new code on WhatsApp. It shows "Resend code in 0:30" and counts down before it works again. A new code replaces the old one.
  • Change number: back to the number, to fix a typing mistake.

What is different from an email account

  • Your login has no email address and no password. You log in with your number and a code: see Log in with your mobile number.
  • No welcome email is sent (there is no address to send it to). If no channel is connected a day after you sign up, and only if you ticked Send me help and updates on WhatsApp, OmniBrand can send you one WhatsApp message instead, "Connect your first channel", with a "Connect a channel" button that opens Accounts. It comes once only. To stop it, turn off Setup help from OmniBrand under notifications on your account.
  • Receipts, team invitations, paying for a plan, broadcasts and a few other actions need an email address. Trying one says "Add an email address first under Your account. Receipts and invitations need one." Add it under Your account, Email address: see Your account. A grey banner at the top of the app says "You log in with your mobile number. Add an email address to get receipts and invite your team." with Add email.
  • Your number is how you log in, so Remove on the Phone number card is refused until you have added an email address.

If something goes wrong

  • "Enter your mobile number and check the country code.": the number is too short or not a number. Check the country code button and the digits.
  • "That is not a mobile number we can use. Pick the country and type the number, or type it with + and the country code (for example +44 7400 123456).": OmniBrand could not read it as a mobile number of that country (or it is a landline). Check the country code and the number.
  • "This number can't receive WhatsApp messages. Continue with Google or email instead.": a few seconds after Send code, WhatsApp reported that the number has no WhatsApp, so the code will not arrive. The code step shows this by itself (it checks for about 45 seconds), with two buttons: Continue with Google takes you to the Google button at the top of the page, and Continue with email opens the Email tab. For another delivery problem it says "WhatsApp couldn't deliver the code to this number. Click Resend code to try again, or continue with Google or email." and Resend code works at once. Another message, "We couldn't send a WhatsApp code to this number. Check the number or use Email sign-up.": WhatsApp did not accept the message, usually because the number has no WhatsApp. Check the number, or click Email and sign up with your email address. The same answer comes straight away, without a new message, when WhatsApp took the last code to this number in the past hour but then reported that it could not deliver it.
  • "This code has expired, or a newer one was sent. Click Resend code to get a new one.": more than 10 minutes passed, or you asked for a newer code. Click Resend code.
  • "That code is not right. Check the newest WhatsApp message and try again. Tries left: (n).": a digit is wrong. After 5 wrong tries the code stops working: "Too many wrong codes. Click Resend code to get a new one."
  • "A code was sent a moment ago. Wait until the button stops counting down, then try again.": wait for Resend code to stop counting down.
  • "Several codes were sent in the last hour. Use the newest WhatsApp message, or try again after (time).": at most 5 codes go to one number in an hour; use the newest message.
  • "This number already has an OmniBrand account." with Log in with your mobile: the number you confirmed already opens an account. Click Log in with your mobile and log in with it.
  • "We could not confirm that you are a person. Complete the check above the button and try again.": tick the box that appears above the button, then click Send code again (on the code step, click Resend code again).
