a really simple integration test Or even a basic design review. Fields that can't be used computationally should never be stored as if they were attribute-free integers. Not only for this risk, but in the specific case of phone numbers, there is positional importance to specific digits (e.g. country code, area/region code, etc.) requiring that left-justification be maintained and zero-padding avoided.
