Simple way is to write your one regular expression based validator. 
 
Or you can use one of the many zipcode + postal code lookup APIs, if you must be correct.
</div>

<div>
But I need some sort of depend. and this isn't working. <pre><code class="code-10 nolinks" id="code-20-43049107-1">$.validator.addMethod('regex', function(value, element, param) { 
&nbsp; &nbsp; &nbsp; &nbsp; return this.optional(element) || 
&nbsp; value.match(typeof param == 'string' ? new RegExp(param) : param); 
&nbsp; &nbsp; }, &nbsp; &nbsp; 'Please enter a value in the correct format.');&nbsp;

$("#form1").validate(
&nbsp; &nbsp;{
&nbsp; &nbsp; &nbsp;&nbsp; rules: {
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Zip : {
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; required: true,
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;regex:"(/\d{5}-\d{4}$|^\d{5}$/)" &nbsp;
//OR 
&nbsp; &nbsp; &nbsp;&nbsp;/* regex: {
&nbsp; &nbsp; &nbsp; &nbsp; 
&nbsp; &nbsp; &nbsp; &nbsp; param: "(/\d{5}-\d{4}$|^\d{5}$/)",
&nbsp; &nbsp; &nbsp; &nbsp; depends: function(element) {
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return $("#Country").val()=='USA' ;
&nbsp; &nbsp; &nbsp; &nbsp; }
&nbsp; &nbsp; &nbsp; }*/
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;
&nbsp; &nbsp; &nbsp;&nbsp;} // end zip
&nbsp; &nbsp;} , //end rules
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;.....

Hi, 
 
Note american can be 5 or 9 digit (ZIP+4) code 
 
I'm using this input mask <a href="http://github.com/RobinHerbots/jquery.inputmask" rel="ugc">http://github.com/RobinHerbots/jquery.inputmask</a> 
This is great because it allow more than one pattern and won't depend of country selection. 
(you can validate server side instead) 
 
with regex 

<pre><code class="code-1 nolinks" id="code-20-43049108-1">$(&quot;#zipcode&quot;).inputmask([&quot;99999[-9999]&quot; , &quot;A9A 9A9&quot; ]); //USA or Canadian Zip Code
</code></pre>
 
And I validate using server side using PHP 
 
First I keep only digits and letters 

<pre><code class="code-1 nolinks" id="code-20-43049108-2">preg_replace('/[^a-zA-Z0-9]/', '', $zipcode); 
</code></pre>
 
And I validate with regex 

<pre><code class="code-1 nolinks" id="code-20-43049108-3">!preg_match ('/^[A-Za-z]\d[A-Za-z]\d[A-Za-z]\d$|^([0-9]{5})([0-9]{4})?$/i', $zipcode)
</code></pre>
</div>

Is there a way to integrate it in to the jquery validation system?&nbsp;

<div class="content wysiwyg-content">
Is there a validation addon for the jquery validation that will validate the zipcode field , if it's american to require only 5 digits, but if the fields for country = 'canada', it should validate as min 6 char and lettes and numbers?

jquery validation for zip or postal code

jQuery (Core) is a cross-browser JavaScript library that provides abstractions for common client-side tasks such as Document Object Model (DOM) traversal, DOM manipulation, event handling, animation and Ajax. jQuery also provides a platform to create plugins that extend jQuery's capabilities beyond those already provided by the library.
