Plate Block Margin Number Format Validator
Validate exact plate-block number text against caller issue-specific accepted literal formats; preserves leading zeros. Caller independently verifies observations, reference edition, units and applicability; not a grading-service certificate, authentication, conservation treatment, actual market price or legal/insurance entitlement.
Description
A plate-block number format can be checked against literal formats already verified for an issue.
A plate-block number format can be checked against literal formats already verified for an issue.1
This validator preserves leading zeros and exact characters, reporting whether the observed string occurs in the supplied accepted list.
When to use Plate Block Margin Number Format Validator
Use this tool when you need to summarize the supplied collecting records or matched observations. Prepare independently verified observations, reference edition/context, and matching units or currency basis.
How to use Plate Block Margin Number Format Validator and understand its results
- Prepare independently verified observations, reference edition/context, and matching units or currency basis.
- Enter observedPlateNumberText, callerAcceptedLiteralFormats, following the field table and calculation rules below, then run the tool.
- Read matchesCallerLiteralFormat. For result objects, inspect the nested output fields below, including any missing evidence or selected indices.
- Correct any input issues and run again. Before using a successful result, review its units, signs, evidence coverage, and stated model or reference assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedPlateNumberText | Observed plate number text | string | Required |
| callerAcceptedLiteralFormats | Caller accepted literal formats | list of string | Required |
Require a nonempty unique list of nonblank accepted formats and compare the observed plate format by exact case-sensitive includes. Return true or false as a successful result; a nonmatching string does not trigger an input error. No numeric coercion or pattern inference occurs.
matches=acceptedLiteralFormats.includes(observedLiteralFormat) Read these symbols with the field meanings and branch or reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| matchesCallerLiteralFormat | Matches caller literal format | boolean |
{
"input": {
"observedPlateNumberText": "0012",
"callerAcceptedLiteralFormats": [

"output": {

}
}Limitations and assumptions
Observations, reference edition, and applicability are independently supplied. Arithmetic and reference summaries do not provide authentication, a certified grade, or an actual market price.
Missing required fields, unknown fields, wrong types, and violated calculation rules return input issues. Arrays must be dense, with no missing cells. Ordinary string lists allow at most 128 strings of at most 128 UTF-16 units each.
Alternative or Complementary methods
For a related task, use Control Block Cylinder Number Parser: A control-block identifier can contain a literal prefix followed by a digit sequence whose leading zeros matter. This parser separates the digits under a supplied prefix rather than treating the whole mark as a number. For a complementary step, use Imprint Block Presence Bottom Margin Checker: An imprint block includes printed marginal information that must be observed relative to an expected format. This checker compares supplied evidence requirements and returns compatible and fully witnessed classes separately.
