haven01 Phone Number Validations
How do I create a validation for phone numbering formatting? Currently users can enter a US phone number or international number, how can I create a validation rule to format the US phone # and international phone # accordingly?
You probably have to combine these 2 formulas with another formula that evaulates the Country field
US Phone
US Phone Number Has Ten Digits Field Value Description: Validates that the Phone number is in (999) 999-9999 format. This works by using the REGEX function to check that the number has ten digits in the (999) 999-9999 format.
Formula: NOT(REGEX(Phone, "\\D*?(\\d\\D*?){10}"))
Error Message: US phone numbers should be in this format: (999) 999-9999. Error Location: Phone
Int'l Phone
Phone Number Has International Format Field Value Description: Validates that the Phone number begins with a plus sign (+) for country code. Note that this validation rule conflicts with the ten-digit rule. Formula: LEFT(Phone, 1) <> "+" Error Message: Phone number must begin with + (country code). Error Location: Phone
