Cannabis License Verifier — batch check license status in 12 US states

Give it a list of cannabis licensees (license numbers and/or business names) and get back, for each one, whether it exists in the official state regulator data, its normalised status (active, inactive, expired, suspended, revoked, pending), the raw regulator status, license type, issue/expiry dates and premises address. Built for compliance, KYC/onboarding, banking, insurance and supply-chain teams that need to re-verify a vendor or customer list — not download a whole state.

No browser, no proxies, no login: every source is a public regulator API, open-data feed or published spreadsheet, fetched live on each run.

Supported states

CO	MED licensed-facility lists (all 9 facility types)	~600 current facilities	Current licensees only (Licensed) + expiry date	Monthly
NV	Cannabis Compliance Board establishment list	~640 active, conditional, surrendered/revoked	Active / Conditional / Surrendered / Revoked	Monthly
MD	Maryland Cannabis Administration data-dashboard workbook	~210 growers, processors, dispensaries, ancillary	Current licensees only (Licensed) + start/expiry	Monthly
ME	Office of Cannabis Policy adult-use workbook + medical establishments & caregivers	~1.9k	Active / Conditional / Pending	Monthly

FL	OMMU licensed MMTC table	~50 MMTC license holders	Initial Licensure / Dispensing Authorization	As published
MI	Cannabis Regulatory Agency Accela portal, full "Download results" CSV export (adult-use + medical facility modules)	~10k records incl. void/closed/suspended/revoked	Active / Active - Late Renewal / License Void / Closed / Suspended / Revoked + disciplinary-action flag	Live (exported from the CRA portal on every run)
OH	Division of Cannabis Control license lists (dispensary, cultivator, processor, testing-lab workbooks)	~320 current dual-use licenses	Current licensees only (Licensed) + issue/expiry; legacy MMCP numbers also match	As published (list dated in the file, updated roughly weekly)

States where the list contains only current licensees (CO, MD, CT, OH) return status: "active" with a statusRaw that says so; a license that has lapsed simply won't match there (matched: false).

Not supported (and why): OR (OLCC moved its license table into a Socrata story with no public tabular feed as of Sep 2026), MO (Tableau only), AZ (regulator PDF last updated 2021), IL (PDF updated Jan 2026, layout too unstable for verification), NM (feed has no license numbers or status), MN / VT / NJ (browser-only portals), RI (blocks cloud requests).

Michigan rows carry the CRA record number (AU-R-…, GR-C-…, PC-…), the Accela status verbatim and a ; disciplinary action on file suffix in statusRaw when the CRA has public disciplinary documents for that license; the export has no issue date. Ohio rows use the dual-use license number (CCD…, CCC…, CCP…, CCL…); a query with the legacy medical-program number (MMCP…) still matches the same record.

Input

{
  "queries": [
    { "state": "CA", "licenseNumber": "C10-0000651-LIC" },
    { "state": "ME", "businessName": "The Cannabis Cabin LLC" },
    { "state": "NY", "businessName": "7 Leaf Clover" },
    { "state": "WA", "licenseNumber": "414884" },
    { "state": "MI", "licenseNumber": "AU-R-001610" },
    { "state": "OH", "businessName": "Ancient Roots LLC" },
    { "businessName": "Curaleaf" }
  ],
  "states": [],
  "matchMode": "fuzzy",
  "maxResultsPerQuery": 3,
  "maxItems": 10
}

Field	Default	Notes
queries	3 sample lookups	Each object: state (2-letter), licenseNumber and/or businessName. Omit state to search every supported state. If both are given the license number is used.
states	[] (all)	Only process queries for these states.
matchMode	fuzzy	fuzzy ignores case, punctuation and entity suffixes (LLC, Inc, Corp…) and tolerates small typos; exact requires the normalised name / license number to match exactly.
maxResultsPerQuery	3	Cap on candidate rows per query (multi-location operators often hold several licenses under one name).
maxItems	10	Cap on total result rows.

License numbers are matched on alphanumerics only, so c10-0000651, C10 0000651 and C10-0000651-LIC all resolve to the same California license (confidence 0.95 when a state suffix is missing, 1.0 on exact).

Output

One row per match, or one row with matched: false when nothing in the state's data matches the query. An unmatched result is a valid verification outcome (the licensee is not on the regulator's list) and is charged like a match. Rows whose note reports an unsupported state or an unreachable source are not charged.

matchConfidence is 0–1: 1 = exact normalised match, 0.95 = license number without state suffix, 0.6–0.95 = fuzzy name match (Dice similarity / whole-word containment). matchedOn tells you whether the hit was on licenseNumber, businessName or dbaName.

Status normalisation

status	Raw regulator values mapped here
active	Active, ACTIVE (ISSUED), Active (renewal on file), Open, Licensed, Approved, Limited Operations, Initial Licensure, Dispensing Authorization
pending	Pending, Conditional, Pending Conditional, In-Process, Payment Pending, PCA / Amendment Under Review, Provisional
inactive	Inactive, Surrendered, Canceled, CLOSED (PERMANENT/TEMPORARY), Not Operating, Former Title Certificate, Withdrawn, Denied
expired	Expired
suspended	Suspended
revoked	Revoked
unknown	anything else — statusRaw always keeps the original text

Pricing

Pay-per-event: a small start fee plus one event per verification row (matched or unmatched). A 500-line vendor list checked across the supported states costs a few dollars — versus a per-state data dump you would still have to join yourself.

Tips

• Sources are downloaded once per run and cached in memory, so batches of hundreds of queries are fast; California is queried per lookup through the DCC search API and needs no bulk download.
• Use matchMode: "exact" for automated re-checks of a list you already resolved once (store the returned licenseNumber and verify by number from then on).
• Query without state to find out where an operator is licensed — each state hit comes back as its own row.
