Toyota Part Number Format

This section describes the Toyota part number format and provides examples of how the parser handles various input formats.

Part Number Structure

A Toyota part number consists of three components:

Component	Length	Description
Part Number Category	5 characters	Identifies the part category
Vehicle Usage Code	5 characters	Identifies the vehicle application
Part Suffix (optional)	2 characters	Supersession or revision identifier

Format Examples

• 90915-YZZJ3 - Basic format with hyphen
• 90915YZZJ3 - Basic format without hyphen
• 90915-YZZJ3-01 - With supersession suffix

Parsing Behavior

The parser is flexible and handles various input formats:

Case Insensitivity

All inputs are normalized to uppercase:

Input	With Hyphens	Without Hyphens
12345ABCDE	12345-ABCDE	12345ABCDE
12345abcde	12345-ABCDE	12345ABCDE
12345-ABCDE	12345-ABCDE	12345ABCDE
12345-abcde	12345-ABCDE	12345ABCDE

With Supersession Suffix

Input	With Hyphens	Without Hyphens
12345ABCDEXY	12345-ABCDE-XY	12345ABCDEXY
12345abcdexy	12345-ABCDE-XY	12345ABCDEXY
12345-ABCDE-XY	12345-ABCDE-XY	12345ABCDEXY
12345-abcde-xy	12345-ABCDE-XY	12345ABCDEXY

Non-Alphanumeric Character Removal

When removeNonAlphanumericCharacters: true is specified, invalid characters are stripped:

Input	With Hyphens	Without Hyphens
12345ABC'DE	12345-ABCDE	12345ABCDE
12@345ABCDE	12345-ABCDE	12345ABCDE
12345A#BCDE	12345-ABCDE	12345ABCDE
12345ABC%DE	12345-ABCDE	12345ABCDE
1&2345ABC%DE	12345-ABCDE	12345ABCDE
12345-ABCDE??	12345-ABCDE	12345ABCDE
12345-ABCDE??	12345-ABCDE	12345ABCDE

Usage

Parsing

// Basic parsing
if (ToyotaPartNumber.TryParse("90915-YZZJ3", out var part))
{
    Console.WriteLine($"Category: {part.PartNumberCategory}"); // 90915
    Console.WriteLine($"Usage: {part.VehicleUsageCode}");      // YZZJ3
    Console.WriteLine($"Suffix: {part.PartSuffix}");           // (empty)
}

// Parsing with non-alphanumeric character removal
if (ToyotaPartNumber.TryParse("90915 YZZJ3", out var part, removeNonAlphanumericCharacters: true))
{
    Console.WriteLine(part.ToString()); // 90915-YZZJ3
}

Formatting

var part = ToyotaPartNumber.Parse("90915YZZJ3");

// With hyphens (default)
Console.WriteLine(part.ToString());      // 90915-YZZJ3
Console.WriteLine(part.ToString(true));  // 90915-YZZJ3

// Without hyphens
Console.WriteLine(part.ToString(false)); // 90915YZZJ3

Equality

Part numbers are compared case-insensitively and hyphen-agnostically:

var part1 = ToyotaPartNumber.Parse("90915-YZZJ3");
var part2 = ToyotaPartNumber.Parse("90915-yzzj3");
var part3 = ToyotaPartNumber.Parse("90915YZZJ3");

// All are equal
Console.WriteLine(part1.Equals(part2)); // true
Console.WriteLine(part1.Equals(part3)); // true
Console.WriteLine(part1.GetHashCode() == part2.GetHashCode()); // true

Valid Formats

? Valid:

• 90915-YZZJ3 - Standard format with hyphen
• 90915YZZJ3 - No hyphen
• 04152-YZZA1 - Different category
• 04152YZZA1 - No hyphen
• 90915-10003 - Numeric usage code
• 90915-YZZJ3-01 - With supersession suffix

? Invalid:

• 123 - Too short
• ?????-????? - Non-alphanumeric (without removal flag)
• 12345-ABCDE-123456 - Suffix too long
• 12345-ABC*EE - Invalid character (without removal flag)
• 12345-123456 - Vehicle usage code is 6 characters (must be 5)
• 123456-12345 - Part category is 6 characters (must be 5)
• 12345-12345-1 - Suffix is 1 character (must be 0 or 2)
• 12345-12345-123 - Suffix is 3 characters (must be 0 or 2)
• 12345-12345- - Trailing hyphen with no suffix

Components

Part Number Category (5 characters)

The first 5 characters identify the general category of the part.

Example: In 90915-YZZJ3, the category is 90915

Vehicle Usage Code (5 characters)

Characters 6-10 identify the specific vehicle application or usage.

Example: In 90915-YZZJ3, the usage code is YZZJ3

Part Suffix (0 or 2 characters)

Optional characters after the 10th position indicate supersession or revision.

Example: In 90915-YZZJ3-01, the suffix is 01
