I'm trying to validate a phone number with Yup:

phone: Yup.number()

  .typeError(That doesn't look like a phone number)

  .positive(A phone number can't start with a minus)

  .integer(A phone number can't include a decimal point)

  .min(8)

  .required('A phone number is required'),

.min(8) validates that the number is 8 or more. So simply entering 8 will pass. How can I make 8 characters required so 1000 0000 would pass?
