There are often times when it’s necessary to validate the data entered by a signer to ensure it matches a specific format. This can include phone numbers, email addresses, passport details, identification numbers, and more. DocuSeal provides the capability to choose from existing validation options for field values or create your own using regular expressions.
To do this, follow these steps:
Validation Type | Example |
---|---|
SSN | 123-45-6789 |
EIN | 12-3456789 |
support@docuseal.co | |
URL | https://docuseal.co |
ZIP | 60604 |
Number only | 123456 |
Letters only | Abcd |
Regular expressions are patterns used to search and validate text to ensure it matches a specific format.
Setting up custom validation for a field is similar to selecting a validation type. Instead of choosing a predefined validation type, select Custom from the list and then enter your regular expression.
Regular expression | Description | Example |
---|---|---|
[A-Z] | Uppercase letters only | ABCD |
^+[1-9]\d{1,14}$ | Phone number in international format | +1234567890 |
^\d{2}-\d{2}-\d{4}$ | Date in DD-MM-YYYY format | 01-01-2024 |
