I had trouble to understand what's "less then 8 numbers". If this really means "less then 8 decimal digits", this answer is correct and the simplest one. My 5.

Thank you, I think I automatically read "Minimum Number is 8" as "At least 8 digits" because phone numbers here in Denmark is 8 digits.

Good guess indeed. OP recommended to formulate requirements thoroughly.
