OB-8945 — license plate combination
OB-8945 is filed as a generated example of the District of Columbia sequential passenger serial — AA-9999 (2 letters + 4 digits). Letters OB sit in positions 1, 2; digits 8945 sit in positions 3, 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 6,760,000 slots, adopted in this atlas from 2013 after AB-1234 slogan rotations.
Disclaimer. OB-8945 is not published here as a real vehicle or plate record. It is a generated example of a serial map for teaching and testing.

District of Columbia format in brief
D.C. slogan plates (taxation, end taxation, etc.) rotate around a short AA-9999 sequential serial rather than a three-letter prefix.
SPR-9932 has three letters and does not match D.C.’s two-letter prefix. Full essay: District of Columbia license-plate format.
Combinatorics for OB-8945
Alphabet size 26 × the digit slots in AA-9999 produces 6,760,000 serials. Rank 3,658,945 is about the 54.1264 percentile of that space (0 = first serial, 100 = last).

Why someone might look up OB-8945
| 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 District of Columbia plate is a physical die issued from a series or a vanity queue. OB-8945 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 District of Columbia motor-vehicle agency, not plates.autos.
Questions about OB-8945
Which state does OB-8945 belong to?
OB-8945 is analysed here as a generated example of the District of Columbia passenger serial (AA-9999). It is not assigned to a motorist by this site. The glyphs fit the sequential passenger skeleton used in this atlas.
Is OB-8945 real?
No claim is made that OB-8945 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 OB-8945 mean?
OB-8945 is a serial, not a slogan. Letters OB occupy positions 1, 2; digits 8945 occupy positions 3, 4, 5, 6. Spoken with the NATO alphabet it reads Oscar · Bravo · eight · nine · four · five.
Which state uses OB-8945?
This page files OB-8945 under District of Columbia because it fits that state’s AA-9999 passenger map. No other jurisdiction in this atlas shares this skeleton for these glyphs. Other states with a different skeleton will reject the same glyphs.
Which vehicle uses OB-8945?
None that this atlas knows of. There is no vehicle make, model, colour, or VIN attached to OB-8945. If you photographed a car, the door-jamb sticker and the registration — not this page — identify the vehicle.
Which state’s format does OB-8945 follow?
District of Columbia sequential passenger plates are taught here as AA-9999 (2 letters + 4 digits), in use in this atlas from 2013. Earlier District of Columbia plates used AB-1234 slogan rotations.
Is OB-8945 a vanity plate?
Probably not, as modelled. Sequential passenger serials are issued in series; vanity (personalised) plates are requested strings that often break AA-9999. OB-8945 fits the sequential map, so this atlas treats it as a series example, not a purchased phrase.
How is OB-8945 read?
Left to right as printed: OB-8945. Aloud: Oscar · Bravo · eight · nine · four · five. Hyphens and spaces are separators in the published pattern, not extra serial values.
Which letters and numbers are in OB-8945?
Letters: OB (2). Digits: 8945 (4). Combined alphanumeric length: 6. Separators in the District of Columbia display form are taken from AA-9999.
How many combinations can the OB-8945 format produce?
The District of Columbia map AA-9999 with a 26-letter alphabet yields 6,760,000 distinct serials. OB-8945 sits at rank 3,658,945 in that mixed-radix order (about the 54.1264 percentile).
Could OB-8945 have been issued before?
It could, mathematically: the string is inside the 6,760,000-slot space. Issuance is a DMV operation (series rolls, skipped blocks, recalls). This page does not query a live file and cannot say whether OB-8945 was ever bolted to a bumper.
Why does OB-8945 appear on Google?
Because plates.autos publishes a stable analysis URL for the combination. Search engines that crawl https://plates.autos/district-of-columbia/license-plate-combinations/ob-8945/ are reading an educational combinatorics page, not a leaked registration. Ranking is not a proof of issuance.
Which country or region is OB-8945 from?
The working assumption on this page is the United States, Northeast region, state of District of Columbia. Other countries use different dies, shields and checksums. A similar glyph string abroad would be a coincidence of alphabet, not a shared registry.
Is OB-8945 a valid US format?
OB-8945 is a valid glyph string under the District of Columbia AA-9999 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 OB-8945?
On the District of Columbia sequential map: letters from ABCDEFGHIJKLMNOPQRSTUVWXYZ and digits 0–9. Skipped letters in this atlas: none modelled. Separators: whatever AA-9999 prints (space, hyphen, or dot). Decorative dies and stacked graphics do not add serial glyphs.
How might OB-8945 have been generated?
Two honest answers. A DMV would emit it by walking the AA-9999 series. This website can also construct it with PHP by placing letters OB and digits 8945 into those slots — which is exactly how a generated example is made. Neither method is a public records search.
Was OB-8945 used in a film or series?
This atlas does not track screen-used plates. Prop departments often invent in-format serials. If OB-8945 appeared on camera, that is outside the dataset here; treat any match as unverified.
Why might OB-8945 be blurred in a photo?
Publishers, Street View pipelines, and news desks often blur plates as a privacy habit, not because OB-8945 is special. A blur is not evidence that the combination is issued, sensitive, or unique.
What are similar plate numbers to OB-8945?
Immediate serial neighbours increment the mixed-radix rank by small deltas (for example OB-8942 and OB-8943). Same-format random draws on this page change on refresh so crawlers can discover more in-class URLs without turning OB-8945 itself into a moving target.
What appears online about OB-8945?
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. OB-8945 as published here is a generated example combination.
