SRC0021 — license plate combination

SRC0021 is filed as a generated example of the Arizona sequential passenger serial — AAA9999 (3 letters + 4 digits). Letters SRC sit in positions 1, 2, 3; digits 0021 sit in positions 4, 5, 6, 7. 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 175,760,000 slots, adopted in this atlas from 2008 after AAA-NNN and cactus graphic series.

Disclaimer. SRC0021 is not published here as a real vehicle or plate record. It is a generated example of a serial map for teaching and testing.

Arizona format in brief

Arizona cycled through county prefixes and desert graphics. The seven-character AAA9999 block expanded capacity without a dash, which is why SPR9932-style strings are analysed here without a hyphen.

Vanity plates in Arizona can break this pattern entirely; this atlas only models the standard passenger serial. Full essay: Arizona license-plate format.

Combinatorics for SRC0021

Alphabet size 26 × the digit slots in AAA9999 produces 175,760,000 serials. Rank 126,120,021 is about the 71.757 percentile of that space (0 = first serial, 100 = last).

Why someone might look up SRC0021

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 Arizona plate is a physical die issued from a series or a vanity queue. SRC0021 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 Arizona motor-vehicle agency, not plates.autos.

Questions about SRC0021

Which state does SRC0021 belong to?

SRC0021 is analysed here as a generated example of the Arizona passenger serial (AAA9999). It is not assigned to a motorist by this site. The glyphs fit the sequential passenger skeleton used in this atlas.

Is SRC0021 real?

No claim is made that SRC0021 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 SRC0021 mean?

SRC0021 is a serial, not a slogan. Letters SRC occupy positions 1, 2, 3; digits 0021 occupy positions 4, 5, 6, 7. Spoken with the NATO alphabet it reads Sierra · Romeo · Charlie · zero · zero · two · one.

Which state uses SRC0021?

This page files SRC0021 under Arizona because it fits that state’s AAA9999 passenger map. The same alphanumeric string also fits Georgia, Michigan, New York, North Carolina, Ohio, Pennsylvania, Texas, Virginia, Washington, Wisconsin. Other states with a different skeleton will reject the same glyphs.

Which vehicle uses SRC0021?

None that this atlas knows of. There is no vehicle make, model, colour, or VIN attached to SRC0021. If you photographed a car, the door-jamb sticker and the registration — not this page — identify the vehicle.

Which state’s format does SRC0021 follow?

Arizona sequential passenger plates are taught here as AAA9999 (3 letters + 4 digits), in use in this atlas from 2008. Earlier Arizona plates used AAA-NNN and cactus graphic series.

Is SRC0021 a vanity plate?

Probably not, as modelled. Sequential passenger serials are issued in series; vanity (personalised) plates are requested strings that often break AAA9999. SRC0021 fits the sequential map, so this atlas treats it as a series example, not a purchased phrase.

How is SRC0021 read?

Left to right as printed: SRC0021. Aloud: Sierra · Romeo · Charlie · zero · zero · two · one. Hyphens and spaces are separators in the published pattern, not extra serial values.

Which letters and numbers are in SRC0021?

Letters: SRC (3). Digits: 0021 (4). Combined alphanumeric length: 7. Separators in the Arizona display form are taken from AAA9999.

How many combinations can the SRC0021 format produce?

The Arizona map AAA9999 with a 26-letter alphabet yields 175,760,000 distinct serials. SRC0021 sits at rank 126,120,021 in that mixed-radix order (about the 71.757 percentile).

Could SRC0021 have been issued before?

It could, mathematically: the string is inside the 175,760,000-slot space. Issuance is a DMV operation (series rolls, skipped blocks, recalls). This page does not query a live file and cannot say whether SRC0021 was ever bolted to a bumper.

Why does SRC0021 appear on Google?

Because plates.autos publishes a stable analysis URL for the combination. Search engines that crawl https://plates.autos/arizona/license-plate-combinations/src-0021/ are reading an educational combinatorics page, not a leaked registration. Ranking is not a proof of issuance.

Which country or region is SRC0021 from?

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

Is SRC0021 a valid US format?

SRC0021 is a valid glyph string under the Arizona AAA9999 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 SRC0021?

On the Arizona sequential map: letters from ABCDEFGHIJKLMNOPQRSTUVWXYZ and digits 0–9. Skipped letters in this atlas: none modelled. Separators: whatever AAA9999 prints (space, hyphen, or dot). Decorative dies and stacked graphics do not add serial glyphs.

How might SRC0021 have been generated?

Two honest answers. A DMV would emit it by walking the AAA9999 series. This website can also construct it with PHP by placing letters SRC and digits 0021 into those slots — which is exactly how a generated example is made. Neither method is a public records search.

Was SRC0021 used in a film or series?

This atlas does not track screen-used plates. Prop departments often invent in-format serials. If SRC0021 appeared on camera, that is outside the dataset here; treat any match as unverified.

Why might SRC0021 be blurred in a photo?

Publishers, Street View pipelines, and news desks often blur plates as a privacy habit, not because SRC0021 is special. A blur is not evidence that the combination is issued, sensitive, or unique.

What are similar plate numbers to SRC0021?

Immediate serial neighbours increment the mixed-radix rank by small deltas (for example SRC0018 and SRC0019). Same-format random draws on this page change on refresh so crawlers can discover more in-class URLs without turning SRC0021 itself into a moving target.

What appears online about SRC0021?

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. SRC0021 as published here is a generated example combination.
