We've released a new gem for all your postal code formatting and validation needs.
Going Postal will validate and correctly format postal codes from the UK, US, Canada, Australia, New Zealand, and South Africa, and can be used as either a model mixin or as a namespaced collection of static methods.
To validate an address, enter as much information about the intended recipient as you can. You will need to include street, city, and state information or a postal code. An exact address match against UPS Address Validation confirms that an address exists in a standard database of address possibilities.
UPS Address Validation compares an address to a standard database of address possibilities.
A successful validation attempt indicates that the address information you provided exists in the database. Chicago, IL 60657-2211Result: The address you entered matched the database.

Simple and flexible usually go together, so a short while later a module with a handful of methods like ) and the code is up on Git Hub.
In any case, all databases are capable of doing adequate syntactic validation when values are inserted or updated.
For example, to prevent empty strings (which are not the same thing as NULL), you can specify a constraint such as: Constraints of this type are declared in the CREATE TABLE statement. There are 256 * 256 = 65536 different ASCII two-character combinations, but only sixty-five of them are official USPS abbreviations.
It currently supports UK, US, Canadian, Australian, New Zealand, and South African postal codes (plus rules to say no postcode is valid in Ireland, as they don't use them), and we'd love to accept contributions to add rules for more countries.
At Jot Form, we want to make sure that you’re getting the online form builder help that you need.
