North Carolina DMV MCP — live wait times at every NCDMV driver license office and license plate agency, plus the office directory the same feed carries. Keyless.

North Carolina and Oregon are the only two US states whose DMV publishes a machine-readable live wait feed. Every other state's is captcha-gated, blocked to cloud egress, broken, or only inside a phone app.

Tools

• nc_dmv_wait_times(office?, service?, open_only?, sort?, limit?) — current average wait, longest wait, and open/closed status per office. 148 driver license offices; service: "vehicle" switches to the vehicle services / license plate agency units.
• nc_dmv_offices(office?, city?, zip?, service?, district?, limit?) — address, city, ZIP, phone, posted hours and NCDMV district. This feed is the only machine-readable NCDMV office directory that exists, so it doubles as the state's office locator.

Auth

None. Keyless and unauthenticated.

Gotchas this pack handles for you

Closed-hours zeros are data, not gaps

Outside posted business hours every office reports OfficeStatus Closed with AvgWT/MaxWT of 0:00:00. That is NCDMV reporting an idle queue — it is neither an error nor a missing value, and it must not be read as "walk right in".

Responses therefore always carry offices_open, and when nothing is open the note says the wait figures are idle-queue zeros. sort: "wait" puts open offices ahead of closed ones for the same reason: a shortest-wait ranking would otherwise be won by 148 closed offices tied at zero.

The feed is a tree, and the sentinel row lies about its parent

UnitID=2 returns 161 <Unit> blocks: one root (Driver Services, UnitLevel 1), eleven districts (level 2), the 148 real offices (level 3), and a sentinel named Invalid. For UnitID=182 the real unit sits at level 2 instead.

So the pack keeps leaves — any UnitId never named as another unit's ParentUnitId — rather than filtering on UnitLevel, which survives NCDOT re-organising the tree.

The ordering matters: the Invalid sentinel hangs off a real office (Greensboro West, ParentUnitId=143). Computing the parent set before dropping Invalid demotes that office out of the results and yields 147 offices where NCDMV publishes 148. Invalid is dropped first.

Addresses

-- is the feed's null. The separate <ZipCode> tag is empty on every single unit, so the ZIP has to be parsed out of the one-line Address string ("521 S. Sandhills Blvd., Aberdeen, NC 28315"). That line is not consistently punctuated: some offices embed newlines, omit the comma before the city, or drop NC altogether ("2479 E. Fifth St., Lumberton 28358"). The parser peels from the right — ZIP, then the state token, then the city at the last comma — and returns the whole string in address with city: null when the city cannot be separated from the street safely.

Current coverage: 118 of 148 offices carry an address at all (NCDMV leaves 30 blank); of those, 118 ZIPs and 116 cities parse. offices_missing_address reports the gap.

Some entries are stale on NCDMV's side — Greensboro Express OLD still appears in the feed. They are returned as published rather than second-guessed.

Wait units

AvgWT / MaxWT are H:MM:SS; the pack converts them to whole minutes.
