Validating Postal Codes

You can use JavaScript Validation to ensure the postal code standard field on contact profiles conforms to a certain pattern. For example, Canadian postal codes follow the pattern of LNL NLN
Where
L = a letter
N = a number

Example: M5V 2H1

Steps

1. Click on Global Settings
2. Under User & Contact Settings, click on the hyperlink for User/Contact Standard Field Settings
3. From the left-hand list of standard fields, click on the hyperlink for Zip / Postal Code
4. In the Validation setting, enter isMatch(@value@, 'LNL NLN', true)
5. Enter a Validation Message, such as "Postal Code must be in the format of 'A#A #A#', example: 'M5V 2H1'."

Now, when a postal code is entered, if the Postal Code is not in the specified format, the user will be prompted with the Validation Message.

To Only Enforce Postal Code Formats for a Particular Country

To only enforce the above formats for users who live in Canada, enter the following into the Validation setting:

document.frmuser.ucountry.value!="10" || isMatch(@value@, 'LNL NLN', true)

Zip Code Format

To enforce a US zip code of 5 or 5+4 digits, enter the following into the Validation setting:

isFloat(@value@.replace(/-/g,""),true) && (isMatch(@value@, 'NNNNN', false) || isMatch(@value@, 'NNNNN-NNNN', false))
