NDC 166 — license plate combination

NDC 166 is filed as a generated example of the Alaska sequential passenger serial — AAA 999 (3 letters + 3 digits). Letters NDC sit in positions 1, 2, 3; digits 166 sit in positions 4, 5, 6. This page does not identify a car, an owner, or a live registration. It measures how the string sits inside a published character map of 12,167,000 slots, adopted in this atlas from 1981 after numeric-only and early gold-on-blue runs.

Disclaimer. NDC 166 is not published here as a real vehicle or plate record. It is a generated example of a serial map for teaching and testing.

Alaska format in brief

Alaska moved from territorial numbering into a letter-digit mix as the vehicle fleet grew. The three-by-three block remains the teaching example because it is short, high-contrast, and still in the passenger series.

I, O and Q are treated as skipped in this atlas to match common die and OCR practice on Alaskan stacks. Full essay: Alaska license-plate format.

Combinatorics for NDC 166

Alphabet size 23 × the digit slots in AAA 999 produces 12,167,000 serials. Rank 6,419,166 is about the 52.7588 percentile of that space (0 = first serial, 100 = last).

Why someone might look up NDC 166

UseNote
Vanity researchPeople compare a wanted phrase against the sequential map so they can see whether it is a standard serial or a specialty request.
Fleet labellingInventories and film-unit vehicles often need a plausible unused-looking serial that still obeys a state’s character classes.
Fiction and propsWriters and set designers pick a combination that could exist on a given state’s dies without copying a photographed car.
Dataset testingOCR, ANPR and form-validation tests need strings that match a published pattern, including separators.
Format teachingThe combination is a worked example of how many plates a map can hold, not a window into a motor-vehicle file.

Generated example versus a real plate

A real Alaska plate is a physical die issued from a series or a vanity queue. NDC 166 on this URL is a string that fits that series’ character classes. Identical glyphs can exist in both worlds; this website has no feed that would let it tell them apart. If you need an official answer, ask the Alaska motor-vehicle agency, not plates.autos.

Questions about NDC 166

Which state does NDC 166 belong to?

NDC 166 is analysed here as a generated example of the Alaska passenger serial (AAA 999). It is not assigned to a motorist by this site. The glyphs fit the sequential passenger skeleton used in this atlas.

Is NDC 166 real?

No claim is made that NDC 166 is currently issued, expired, or reserved. The string sits inside a published character map. Whether a DMV ever stamped it is a registration fact this atlas does not observe.

What does NDC 166 mean?

NDC 166 is a serial, not a slogan. Letters NDC occupy positions 1, 2, 3; digits 166 occupy positions 4, 5, 6. Spoken with the NATO alphabet it reads November · Delta · Charlie · one · six · six.

Which state uses NDC 166?

This page files NDC 166 under Alaska because it fits that state’s AAA 999 passenger map. The same alphanumeric string also fits Hawaii, Iowa, Louisiana, Minnesota, Mississippi, Nebraska, Oklahoma, South Carolina, Vermont. Other states with a different skeleton will reject the same glyphs.

Which vehicle uses NDC 166?

None that this atlas knows of. There is no vehicle make, model, colour, or VIN attached to NDC 166. If you photographed a car, the door-jamb sticker and the registration — not this page — identify the vehicle.

Which state’s format does NDC 166 follow?

Alaska sequential passenger plates are taught here as AAA 999 (3 letters + 3 digits), in use in this atlas from 1981. Earlier Alaska plates used numeric-only and early gold-on-blue runs.

Is NDC 166 a vanity plate?

Probably not, as modelled. Sequential passenger serials are issued in series; vanity (personalised) plates are requested strings that often break AAA 999. NDC 166 fits the sequential map, so this atlas treats it as a series example, not a purchased phrase.

How is NDC 166 read?

Left to right as printed: NDC 166. Aloud: November · Delta · Charlie · one · six · six. Hyphens and spaces are separators in the published pattern, not extra serial values.

Which letters and numbers are in NDC 166?

Letters: NDC (3). Digits: 166 (3). Combined alphanumeric length: 6. Separators in the Alaska display form are taken from AAA 999.

How many combinations can the NDC 166 format produce?

The Alaska map AAA 999 with a 23-letter alphabet yields 12,167,000 distinct serials. NDC 166 sits at rank 6,419,166 in that mixed-radix order (about the 52.7588 percentile).

Could NDC 166 have been issued before?

It could, mathematically: the string is inside the 12,167,000-slot space. Issuance is a DMV operation (series rolls, skipped blocks, recalls). This page does not query a live file and cannot say whether NDC 166 was ever bolted to a bumper.

Why does NDC 166 appear on Google?

Because plates.autos publishes a stable analysis URL for the combination. Search engines that crawl https://plates.autos/alaska/license-plate-combinations/ndc-166/ are reading an educational combinatorics page, not a leaked registration. Ranking is not a proof of issuance.

Which country or region is NDC 166 from?

The working assumption on this page is the United States, West region, state of Alaska. Other countries use different dies, shields and checksums. A similar glyph string abroad would be a coincidence of alphabet, not a shared registry.

Is NDC 166 a valid US format?

NDC 166 is a valid glyph string under the Alaska AAA 999 sequential passenger model used in this atlas. Validity here means “fits a documented sequential passenger skeleton,” not “cleared by a motor-vehicle agency.” Optional, military, and government plates are out of scope.

Which characters can appear on NDC 166?

On the Alaska sequential map: letters from ABCDEFGHJKLMNPRSTUVWXYZ and digits 0–9. Skipped letters in this atlas: IOQ. Separators: whatever AAA 999 prints (space, hyphen, or dot). Decorative dies and stacked graphics do not add serial glyphs.

How might NDC 166 have been generated?

Two honest answers. A DMV would emit it by walking the AAA 999 series. This website can also construct it with PHP by placing letters NDC and digits 166 into those slots — which is exactly how a generated example is made. Neither method is a public records search.

Was NDC 166 used in a film or series?

This atlas does not track screen-used plates. Prop departments often invent in-format serials. If NDC 166 appeared on camera, that is outside the dataset here; treat any match as unverified.

Why might NDC 166 be blurred in a photo?

Publishers, Street View pipelines, and news desks often blur plates as a privacy habit, not because NDC 166 is special. A blur is not evidence that the combination is issued, sensitive, or unique.

What are similar plate numbers to NDC 166?

Immediate serial neighbours increment the mixed-radix rank by small deltas (for example NDC 163 and NDC 164). Same-format random draws on this page change on refresh so crawlers can discover more in-class URLs without turning NDC 166 itself into a moving target.

What appears online about NDC 166?

You may find this analysis, forum guesses, or unrelated hits (part numbers, product SKUs). None of those sources, including plates.autos, is a substitute for a state records request. NDC 166 as published here is a generated example combination.
