driverlicenseverificationresult, their values will be "true" (if validation for corresponding request param is successful), "false" (if validation for corresponding request param is failure) or "" (if the corresponding request param is either not provided from the client or has invalid/corrupt value) confidence score logic our validation process checks specific details like names, license numbers, and dates you provide each detail has a different importance the api checks specific details to calculate a validation score namely \['driverlicensenumber', 'firstname', 'lastname', 'statecode', 'persondob', 'driverlicenseissuedate', 'driverlicenseexpirationdate'] weight importance each detail has a different level of importance in the check for instance 'driverlicensenumber' matching is most crucial (given the highest weight of 0 50) exact matches in 'firstname' or 'lastname' are important too (weighted at 0 10 each), while close matches count a bit less (0 075) 'state' match, birthdate, and specific dates on the license carry moderate weight (0 10) dates like 'driverlicenseissuedate' and 'driverlicenseexpirationdate' are less critical (0 05) scoring system the api assigns scores to each detail based on whether they match exactly or closely these scores are added up, and if the total reaches 1, it means everything matched perfectly if the total is slightly less than 1, it implies some details didn't match as well validation threshold the goal is to achieve a combined score of 0 70 or higher this benchmark ensures that most parts match well if the total score meets or exceeds 0 70, the api considers it a successful validation if it falls below, it indicates some discrepancies in general, we suggest keeping the passing score at 0 70 or higher to ensure a strong verification if you're unsure, we can leave it as is, and we'll use 0 70 as the default passing score for the verification states supported by dmv state abbreviation state name al alabama az arizona ar arkansas co
