National ID & Tax ID Validator

Catch fake and mistyped ID numbers in bulk, and get the data hidden inside them: birth date, sex, region and more. 222 ID types from 108 countries and territories, plus passport MRZ.

What you get

• Validation: checksum check wherever a public algorithm exists
• Decoding: date of birth, sex, region or place of birth, citizenship, serial number, depending on the type
• Derived identifiers: data that follows from the number itself, e.g. the official <personal code>@eesti.ee e-mail address of Estonian ID card holders, or the place of birth from a French INSEE number
• Auto-detection: no need to know the document type; every type the value fits is returned
• Formatted value: the number in its usual printed layout

Use cases

• KYC onboarding: reject typos and invented numbers before paying for full verification
• Consistency checks: compare the birth date and sex encoded in an ID with what the user entered
• Data cleaning: classify and normalize identifier columns in bulk

Input

Field	Required	Description
values	yes	Identifiers, one per line
country	no	ISO 3166 alpha-3 (or alpha-2), e.g. EST. Only this country's types are tried
type	no	Exact type, e.g. est_personal_id, taken from an earlier run

{"values": ["37605030299"], "country": "EST"}

Output

One row per matching type:

{
  "value": "37605030299",
  "valid": true,
  "type": "est_personal_id",
  "checksum_verified": true,
  "formatted": "37605030299",
  "fields": {"email": "37605030299@eesti.ee", "yyyymmdd": "1976-05-03", "gender": "male", "sn": "029", "checksum": 9}
}

• valid: true = a checksum matched; false = nothing matched; null = no country or type given, or only format-only types matched. Without a hint it stays null because short numbers from different countries often share a format and a random number passes some country's checksum about a third of the time.
• checksum_verified: false means only the format matched: the type has no public checksum.
• A value that fits no type gives one row with empty type.

Pricing

You pay per identifier checked, however many types it matches.

Privacy

Identifiers are not logged or stored by us. They end up only in your own dataset.

Limitations

• Not a registry check. A valid number may never have been issued, or may belong to someone else.
• Passport MRZ: the two-line passport format (TD3) only; ID-card and visa MRZ are not supported.
