First of all you have to create a new validation rule and then apply it to your field at a data template level. For example, if you want to validate your numeric value by a regular expression like ^(\d{6,12})$ then you will need to:

1. Create a new Validation Rule in /sitecore/system/Settings/Validation Rules/Field Rules/ folder with Sitecore.Data.Validators.FieldValidators.RegexValidator,Sitecore.Kernel Type and specify your regular expression in Parameters field see an example here

2. Apply the validation rules to the required field by selecting your newly created Validation Rule in Quick Action Bar, Validate Button, Validator Bar properties under the Validation Rules section for your specific field in the corresponding data template see an example here

From now on you can validate your data input during editing, for example via Preview -> Validation action in Sitecore menu.
