# Test Data
By default, VGS Collect SDKs include pre-built validations. To make your integration easier, we provide the list of test data below.
* [Credit and Debit Cards](#test-credit-and-debit-cards)
* [Card Expiration Date](#test-card-expiration-date)
* [Social Security Number(US)](#test-social-security-numberus)
## Test Credit and Debit Cards
Check the valid list of default Card Brands and their details:
| **Card Brand** | **Card Length** | **Test Cards** |
| ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- |
|  **Visa** | 13, 16, 19 |
|
* Default **Checksum** validation for all card brands(except UnionPay) is done with the [Luhn Algorithm](https://en.wikipedia.org/wiki/Luhn_algorithm).
* Default **CVC/CVV** length for **AMEX** is 4 digits, for all other card brands - 3 digits.
> If you need more testing data, you can use online services that allow you to generate luhn-valid card numbers for testing purposes.
## Test Card Expiration Date
Card Expiration Date can be any date in the future, but no more than 20 years from the current month.
By default, VGSCollect SDKs support card date in short(**mm/yy**) and long(**mm/yyyy**) formats, which depend on your configuration.
**Card Expiration Date Test Data**
| **mm/yy** | **mm/yyyy** |
| --------- | ----------- |
| 01/25 | 01/2025 |
| 12/40 | 12/2040 |
## Test Social Security Number(US)
There are a few limitations for valid Social Security Numbers in the US:
* It should have 9 digits.
* It should be divided into 3 parts by a hyphen (-).
* The first part should have 3 digits and should not be 000, 666, or between 900 and 999.
* The second part should have 2 digits, and it should be from 01 to 99.
* The third part should have 4 digits, and it should be from 0001 to 9999.
Also, there are [additional](https://fmx.cpa.texas.gov/fm/pubs/payment/payee_setup/index.php?s=validation\&p=validation) Invalid SSNs(e.g.: `123-45-6789` is an invalid SSN).
**Test SSN Data**
| **SSN** |
| ----------- |
| 123-45-6788 |
| 222-22-2223 |
| 555-66-7777 |
