    Hi Kasb Life,

    Thanks for reaching out to Jotform Support. To achieve a phone number field that starts with a "+" followed by 7 to 14 digits, you can use the Input Mask feature in Jotform's Phone field. Here's how to set it up:

    1.  In Form Builder, click on Add Element on the left side of the page.

    2. Then, in the Form Elements menu, under the Basic tab, scroll down the list and choose the Phone field.

    3. Now, just drag and drop it to your form.

    4. Click on the Gear icon to access phoneproperties.

    5. Under Phone properties, click on Options.

    6. In the Input mask, enter with a fixed "+" character, then use the number mask symbol # for digits. For example, you can use +############## where the number of # symbols corresponds to the number of digits allowed.
