SRC 300 — license plate combination
SRC 300 is filed as a generated example of the Iowa sequential passenger serial — AAA 999 (3 letters + 3 digits). Letters SRC sit in positions 1, 2, 3; digits 300 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 17,576,000 slots, adopted in this atlas from 1997 after county numeric plates.
Disclaimer. SRC 300 is not published here as a real vehicle or plate record. It is a generated example of a serial map for teaching and testing.

Iowa format in brief
Iowa dropped county-number bases in the 1990s in favour of a simple three-by-three serial on a sky-and-field graphic.

Combinatorics for SRC 300
Alphabet size 26 × the digit slots in AAA 999 produces 17,576,000 serials. Rank 12,612,300 is about the 71.7587 percentile of that space (0 = first serial, 100 = last).

Why someone might look up SRC 300
| Use | Note |
|---|---|
| Vanity research | People compare a wanted phrase against the sequential map so they can see whether it is a standard serial or a specialty request. |
| Fleet labelling | Inventories and film-unit vehicles often need a plausible unused-looking serial that still obeys a state’s character classes. |
| Fiction and props | Writers and set designers pick a combination that could exist on a given state’s dies without copying a photographed car. |
| Dataset testing | OCR, ANPR and form-validation tests need strings that match a published pattern, including separators. |
| Format teaching | The 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 Iowa plate is a physical die issued from a series or a vanity queue. SRC 300 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 Iowa motor-vehicle agency, not plates.autos.
Questions about SRC 300
Which state does SRC 300 belong to?
SRC 300 is analysed here as a generated example of the Iowa 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 SRC 300 real?
No claim is made that SRC 300 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 SRC 300 mean?
SRC 300 is a serial, not a slogan. Letters SRC occupy positions 1, 2, 3; digits 300 occupy positions 4, 5, 6. Spoken with the NATO alphabet it reads Sierra · Romeo · Charlie · three · zero · zero.
Which state uses SRC 300?
This page files SRC 300 under Iowa because it fits that state’s AAA 999 passenger map. The same alphanumeric string also fits Alaska, Hawaii, Louisiana, Minnesota, Mississippi, Nebraska, Oklahoma, South Carolina, Vermont. Other states with a different skeleton will reject the same glyphs.
Which vehicle uses SRC 300?
None that this atlas knows of. There is no vehicle make, model, colour, or VIN attached to SRC 300. If you photographed a car, the door-jamb sticker and the registration — not this page — identify the vehicle.
Which state’s format does SRC 300 follow?
Iowa sequential passenger plates are taught here as AAA 999 (3 letters + 3 digits), in use in this atlas from 1997. Earlier Iowa plates used county numeric plates.
Is SRC 300 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. SRC 300 fits the sequential map, so this atlas treats it as a series example, not a purchased phrase.
How is SRC 300 read?
Left to right as printed: SRC 300. Aloud: Sierra · Romeo · Charlie · three · zero · zero. Hyphens and spaces are separators in the published pattern, not extra serial values.
Which letters and numbers are in SRC 300?
Letters: SRC (3). Digits: 300 (3). Combined alphanumeric length: 6. Separators in the Iowa display form are taken from AAA 999.
How many combinations can the SRC 300 format produce?
The Iowa map AAA 999 with a 26-letter alphabet yields 17,576,000 distinct serials. SRC 300 sits at rank 12,612,300 in that mixed-radix order (about the 71.7587 percentile).
Could SRC 300 have been issued before?
It could, mathematically: the string is inside the 17,576,000-slot space. Issuance is a DMV operation (series rolls, skipped blocks, recalls). This page does not query a live file and cannot say whether SRC 300 was ever bolted to a bumper.
Why does SRC 300 appear on Google?
Because plates.autos publishes a stable analysis URL for the combination. Search engines that crawl https://plates.autos/iowa/license-plate-combinations/src-300/ are reading an educational combinatorics page, not a leaked registration. Ranking is not a proof of issuance.
Which country or region is SRC 300 from?
The working assumption on this page is the United States, Midwest region, state of Iowa. Other countries use different dies, shields and checksums. A similar glyph string abroad would be a coincidence of alphabet, not a shared registry.
Is SRC 300 a valid US format?
SRC 300 is a valid glyph string under the Iowa 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 SRC 300?
On the Iowa sequential map: letters from ABCDEFGHIJKLMNOPQRSTUVWXYZ and digits 0–9. Skipped letters in this atlas: none modelled. Separators: whatever AAA 999 prints (space, hyphen, or dot). Decorative dies and stacked graphics do not add serial glyphs.
How might SRC 300 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 SRC and digits 300 into those slots — which is exactly how a generated example is made. Neither method is a public records search.
Was SRC 300 used in a film or series?
This atlas does not track screen-used plates. Prop departments often invent in-format serials. If SRC 300 appeared on camera, that is outside the dataset here; treat any match as unverified.
Why might SRC 300 be blurred in a photo?
Publishers, Street View pipelines, and news desks often blur plates as a privacy habit, not because SRC 300 is special. A blur is not evidence that the combination is issued, sensitive, or unique.
What are similar plate numbers to SRC 300?
Immediate serial neighbours increment the mixed-radix rank by small deltas (for example SRC 297 and SRC 298). Same-format random draws on this page change on refresh so crawlers can discover more in-class URLs without turning SRC 300 itself into a moving target.
What appears online about SRC 300?
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. SRC 300 as published here is a generated example combination.
