Hybrid Input Validation
Identity Verification does as much as possible to ensure the user data it helps you collect and verify is clean and standardized. If you're getting all your user data for Identity Verification entirely from the Link flow, then you don't need to worry about the validations described below. If you are submitting data about the user via the API (e.g. for a hybrid or fully API-based verification approach), you will need to match the formatting and standardization requirements described below.
To help with development, we also provide a JSON file containing the same validation rules.
ID Numbers
Plaid's Data Source Verification will automatically collect, validate, and verify any of the following ID numbers for countries that you've enabled in the Dashboard Editor.
If you are separately collecting ID numbers outside of Link, or if you have existing customer data you're looking to import into Plaid, you can submit this data to the Identity Verification API programmatically via /identity_verification/create or the /link/token/create user object.
The table below lists each ID number that Identity Verification supports. The API type is a unique identifier that you should provide via API via the id_number.type field.
ID Numbers submitted via API should be stripped of any formatting characters like spaces, periods, and dashes. The table below also includes the exact regular expressions we use to decide whether a given ID Number is well-formed and valid for that region's ID type.
Plaid may perform additional validation to ensure the ID number is valid for the selected type. For example, the SSA will not issue SSNs with specific numbers in certain positions. SSNs that meet any of the following conditions will not be accepted:
- Begin with “9”, “666”, or “000”
- Have the number “00" in positions 4 – 5
- Have the number “0000” in positions 6 – 9

Input Validation by Country
Address standards vary by country. Some countries do not support postal code or region (the equivalent of "state" or "province" depending on the region). In other countries, postal code and/or region is valid in a sense, but superfluous and not typically collected in native forms.
Separately, variations in identity data coverage mean that collection of "ID Number" is a required part of Data Source Verification in some countries, optional (configured in the Dashboard Editor) for other countries, and not supported in countries that do not support Data Source Verification at all.
This regional variation is reflected in the table below.
The labels for each input field below correspond to the following input validations:
address.postal_codeandaddress.regionRequired - If
addressis provided as part of the request, this field must always be presentNot Accepted - If
addressis provided as part of the request, this field must be omitted. Specifically, the key should be omitted from theaddressobject (as opposed to the key being present with a null value)
id_numberRequired - If
id_numberis not provided for this country,kyc_checkwill treat the Identity Verification Session as having incomplete data and will require user interaction with the Identity Verification modal in order to collectid_numberOptional - If
id_numberis not provided for this country and your Identity Verification Template is configured to not collect ID numbers for this country then Identity Verification will automatically run thekyc_checkstep without any user interaction as long as all other required input fields are provided. Similar to the address fields, the API requires you omit theid_numberkey entirely if you are not providing ID number dataNot Accepted - ID number verification is not supported for this country and the
id_numberfield should always be omitted from API requests
