idcheckVerify South Dakota driver's licenses

Every layer we run on a South Dakota license
These checks run on every South Dakota verification — no per-feature upsell on the core flow.
-
AAMVA PDF417 decode
Full CDS v01–v12 parse of the South Dakota 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 format validation
The barcode's DAQ license number is validated against the South Dakota pattern: 6–10 digits, or 12 digits.
-
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 South Dakota's AAMVA issuer record.
-
DMV verification (DLDV add-on)
South Dakota participates in AAMVA DLDV — a live check of license number, name, and DOB against the state DMV record, enableable as an add-on.
The South Dakota license-number format
6–10 digits, or 12 digitsThe barcode's DAQ element carries the license number. idcheck.now validates it against the published South Dakota 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.
What the South Dakota PDF417 barcode tells us
A sample of the AAMVA CDS elements decoded from every South Dakota barcode, and what each one feeds into.
| Element | Meaning | How 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. |

Yes — South Dakota participates in AAMVA's DLDV (Driver's License Data Verification) program, and a live DMV check is available as an add-on on any paid tier.
