Verify Florida driver's licenses

Capture a Florida license front and back and idcheck.now decodes the AAMVA PDF417 barcode, validates the 1 letter + 12 digits license number by recomputing it from the holder's name and birthdate, and cross-checks every encoded field against the printed card.

What we check

Every layer we run on a Florida license

These checks run on every Florida verification — no per-feature upsell on the core flow.

  • AAMVA PDF417 decode

    Full CDS v01–v12 parse of the Florida barcode — decoded live in the browser and again independently server-side. Any mismatch is a tamper signal.

  • Mandatory-field enforcement

    DCS, DAC, DBB, DBA, DAQ, and address elements must be present and well-formed per the AAMVA CDS.

  • License-number recomputation

    The Florida number is recomputed from the holder's surname (Soundex), first/middle name codes, birth year, and day code — then compared to the barcode's DAQ field segment by segment.

  • Barcode ↔ OCR cross-check

    Encoded fields are compared against the printed visual zone — name, DOB, expiry, and license number must agree.

  • Expiry & age validation

    DBA (expiration) is enforced against the validity window; DBB (birth date) drives per-session age thresholds.

  • Issuing-authority IIN check

    The issuer identification number in the barcode header is checked against Florida's AAMVA issuer record.

  • DMV verification (DLDV add-on)

    Florida participates in AAMVA DLDV — a live check of license number, name, and DOB against the state DMV record, enableable as an add-on.

License-number format

The Florida license-number format

1 letter + 12 digits

The barcode's DAQ element carries the license number. idcheck.now validates it against the published Florida pattern as a plausibility signal — formats drift over time and legacy cards remain in circulation, so a format miss is a warning fed into the composite score, not an automatic decline.

For Florida, this is only the first step: the number is also recomputed from the holder's identity — see the deep dive below.

Fraud deep dive

Florida license numbers are derived, not assigned

SSSS FFF YY DDD N

Florida computes the license number from the holder's identity. The first four characters are the Soundex code of the surname (one letter plus three digits). The next three digits are a first-name code plus a middle-initial code from the published Gallian code table — for example JAMES = 440 and MARY = 580, with names not in the table falling back to a first-initial code.

The following two digits are the birth year, and the final three-digit day code is (month − 1) × 40 + day, with 500 added for female holders. A June 9th birthday encodes as (6−1)×40 + 9 = 209 for a male and 709 for a female.

idcheck.now recomputes all five segments from the barcode's name and DOB fields and compares them to the DAQ license number. A fabricated number that wasn't derived from the claimed identity fails this check — it is one of the strongest forgery signals we produce.

Inside the barcode

What the Florida PDF417 barcode tells us

A sample of the AAMVA CDS elements decoded from every Florida barcode, and what each one feeds into.

ElementMeaningHow idcheck.now uses it
DAQ Customer ID / license number The license number itself — validated against the state format and, for FL/IL/WI/MO, recomputed from the holder's identity.
DCS Customer family name Mandatory. Soundex-encoded into the license number in FL/IL/WI; cross-checked against the printed card everywhere.
DAC Customer first name Mandatory. Mapped to a first-name code (Gallian table) inside FL/IL/WI license numbers.
DBB Date of birth Mandatory. Encoded into the FL/IL/WI day-code segment and the Missouri trailing digits; drives age checks.
DBA Document expiration date Mandatory. Enforced against the document validity window on every verification.
State DMV verification

AAMVA DLDV for Florida

DLDV participant

Florida participates in AAMVA's DLDV program. As an add-on, idcheck.now can submit the license number, name, and date of birth to the Florida DMV through DLDV and return the state's own verdict — the strongest confirmation short of an in-person check.

Most US jurisdictions participate in DLDV; participant lists and response fields change over time. Confirm availability for Florida at integration time.

FAQ

Florida verification questions

What format is a Florida driver's license number?

Florida driver's license numbers are 1 letter + 12 digits. idcheck.now validates the barcode's DAQ field against this pattern on every verification; older card layouts still in circulation are handled as plausibility warnings rather than hard failures.

Can a fake Florida license number pass idcheck.now?

Not easily. Florida derives license numbers from the holder's surname (Soundex), first and middle names (Gallian code table), birth year, and a birth-date day code that also encodes sex. idcheck.now recomputes the expected number from the barcode's name and DOB fields and compares it segment by segment — a fabricated number that wasn't derived from the claimed identity fails the check.
