Hawaii and Nevada require one county parameter on license lookups and searches. Names are case-insensitive, and surrounding whitespace is ignored. Missing, blank, repeated, or unrecognized values return 400 validation_error. Numeric IDs and FIPS codes are not accepted. Your API key must have access to the requested state.

​
Hawaii

Use the issuing county. The same license number can exist in more than one county.
Lookup
Search
A lookup in a supported county returns 404 license_not_found if there is no match. A search returns 200 with data: []. The API does not fall back to another county. To search both supported counties, send a request for each. There is no statewide search or county=all option. Store Hawaii licenses using (state, address.county, license). Include types[].type when identifying a particular license type. For example, hi / MAUI / 441 and hi / HONOLULU / 441 identify different licenses. Type codes include the issuing county, such as MAUI:PERMANENT.

​
Nevada

Use the geographic county. Coverage currently includes unincorporated Clark County, Las Vegas, North Las Vegas, Henderson, Boulder City, and Mesquite. county=clark includes all six issuing authorities.
Lookup
Search
City-issued licenses use the same filter. For example: /v2/license/nv/L09-00003?county=clark. Preserve punctuation and leading zeros in license numbers.

​
Accepted counties

Accepted values are carson city, churchill, clark, douglas, elko, esmeralda, eureka, humboldt, lander, lincoln, lyon, mineral, nye, pershing, storey, washoe, and white pine. Use the full name without a County suffix. Abbreviations (cl), city names (las vegas), and county=all are invalid. Carson City is accepted as a county-equivalent. Recognized counties outside Clark County are valid filters, but have no data. Lookup returns 404 license_not_found; search returns 200 with data: []. This differs from Hawaii, where requests for Hawaii County and Kauai are rejected.

​
Issuing agencies

The county filter does not select an issuer. In the November response, each types[].agency identifies the agency that issued that type. It contains id, object, name, and url, or is null when the issuer is unknown. Type codes also retain their issuer prefix, such as CLARK_COUNTY:LIQ-118 or LAS_VEGAS:L16. The county and city in an address are not enough to identify the issuer. Retrieve a state lists the agencies registered for covered Nevada jurisdictions.

​
Source limitations

All six sources are checked daily. Henderson publishes weekly, so daily checks may return unchanged records. Clark County, Las Vegas, and North Las Vegas publish historical statuses where available. Henderson, Boulder City, and Mesquite publish active inventories. Clark County’s listing omits owner, phone, original issuance, and expiration fields. Those values are null.

​
Update existing requests

Add county to both lookup and search requests for hi and nv. Other states do not require it. For Hawaii, keep the issuing county with any stored license number.
