By default, WP Affiliate Manager’s fields have built-in validation to handle 10-digit phone numbers and 5-digit numeric zip codes. This, however, does not mean you can’t use the WP Affiliate Manager in your country.
In your WP-Admin, go to Affiliates -> Settings, and then click on the “Affiliate Registration” tab. You can disable the default “US” fields by unchecking the checkbox in the “Enabled” column. Then you can replace those fields with a custom field of your own by clicking the “Add Custom Field” button.
In the “Custom Field” dialog, you can create a new field to capture your Phone, Province, Post Code or whatever else you’d like to add. By using a “Text” Field Type you can set a maximum length, or by using a “Number” Field Type validation will ensure it’s all digits.
