πΊπΈ United States: Driver's License / SSN
SSN: 9 digits (AAA-GG-SSSS). Driver's License varies by state (6-12 alphanumeric). Passport: 9 alphanumeric chars.
The code β fill in the blanks and open a PR
// packages/verify-local/src/document/countries/US.ts
import { CountryVerifier, DocumentResult, NumberValidation } from "../verifier.interface";
const US: CountryVerifier = {
countryCode: "US",
countryName: "United States",
documentTypes: ["drivers_license", "ssn"],
parse(ocrText: string): DocumentResult {
// Driver's License / SSN format: SSN 9 digits or DL varies by state
const doc_number = ocrText.match(/([A-Z0-9]{6,12})/)?.[1] ?? "";
return { valid: !!doc_number, doc_number, country: "US" };
},
validate(docNumber: string): NumberValidation {
// basic alphanumeric check (state-specific validation varies)
return { valid: /^[A-Z0-9]{6,12}$/.test(docNumber) };
},
};
export default US;
Then add one line in registry.ts:
import US from "./countries/US";
// add to registry map: "US": US,
