Hot Wheels have their own unique identifying characteristics. Each model has a ton of subtle information that allows identifying exactly what makes each car unique. To help us maintain consistent and relevant data on each casting, we’ve created a list of Hot Wheels data entry standards to keep everyone on the same page. If you have any questions or suggestions for these standards, feel free to contact us with the green "Contact hobbyDB" button on the right.



  1. Adding New Cars (Variants and Subvariants): With the exception of new castings every Hot Wheels model will have variants and most will have Subvariants. Customs are added as a variant of the original casting, but have the customizer's name set as the brand instead of Hot Wheels. More on how to add customs here.

    Always search for the casting and use "New Item" -> "Add Variant" to create a new entry if other variants of the casting already exist in the database. Subvariants are items with only minor differences, such as a different wheel type or a different packaging style. 

    More on how to create new items here.

    More info on Subvariants:
  2. Images: The Main Image should ideally be the car on the card or on its box and the Show on Search Photo should be the car loose. Both ideally on white (or even better, transparent) background. Subvariants should have a Detail Image to show the differences between Subvariants. Only add images you have permission from the copyright holder to add. Add as many other images as you think make sense. More on photos here.

  3. Name: Always use the name on the package. If it’s a set car without a name on the package, or is loose, use the name on the base or the common casting name. Please do not use custom names like "3-Window" or "’34 with missing tampo". More information on Names here.

  4. Alternate Name: If the item's packaging has a different name from the normal casting name, add it here. Example: If the name on the card is “Mom’s Pro ’34” from the Mother’s Wax exclusive, you would enter “3-Window ’34” (standard name for the casting) as the alternate name.

  5. Brand: This should always be Hot Wheels (unless it a Custom, for more on those see here).

  6. Series: This is the most powerful field as it places the item on related pages/lists on the site. A Series is a group of products made by the same manufacturer, linked by being the same type of item and frequently by theme, scale or similar characteristics.
    • A mainline car should have "Mainline" and its segment series (such as "First Editions" or "HW Flames") listed. Do not include the year in the Series name since we can filter by year within series lists.

  7. Related Subjects: This field is for associating the item with any other applicable subjects. These subjects are shown on search results and can be used to filter searches. Some common Related Subjects are the make of the real-life car, casting designer, and livery or sponsors.

  8. Model: This is the model name of the real-life car. For example, the "Volkswagen 'Classic Bug'" casting would have "Beetle" in this field.

  9. Body Type: Sedan, convertible, SUV, etc.

  10. Production Status: This provides a number of classifications from which you can select. Use only the following statuses for Hot Wheels:
    • "Chase" - Regular Treasure Hunt cars. Super Treasure Hunt cars should use "Super Chase"
    • "Custom" - More info here
    • "Error" - Factory production mistakes, such as wrong wheel types, wrong card, missing decoration, etc.
    • "Exclusive" - Exclusive to a certain retailer, such as Target or Walmart
    • "Limited Edition" - items produced in intentionally-limited quantities as indicated on the package
    • "Premium" - the more collector-oriented models such as Hot Wheels Boulevard, RLC , and Team Transport. Do not use "Deluxe"
    • "Promotional" - items given away as part of a promotion, for example cars included in cereal boxes or McDonald's Happy Meals.
    • "Prototype" - pre-production model
    • "Regional" - only released in a specific country or region
    • "Set Exclusive" - only available in a multipack, track set, or play set
    • "Standard" - items that are just regular production (mainline cars)
    • "Super Chase" - Super Treasure Hunt cars

  11. Released: Unless there is an advertised release date, just enter the year the item was released in or intended for. The next year's mainline cars usually start appearing in stores in the fourth quarter of the year, so even though 2016 cars could be found in late 2015 they are still considered to be released in 2016.

  12. Discontinued: If the car was produced for multiple years (uncommon for Hot Wheels) enter the last year of production here. Otherwise this field can be left blank.

  13. # Produced: Enter the number of items that were produced, if known. Example: 2014 Gulf Drag Bus from the RLC had 4,000 produced. 

  14. Made in: Enter the country/region where the car was made, usually embossed on the baseplate or printed on the packaging. The only currently known options for Hot Wheels are China, France, Hong Kong, India, Indonesia, Macau, Malaysia, Mexico, Thailand, United States, and Venezuela.

  15. Scale: Enter the scale. Standard scales Hot Wheels are 1/18, 1/24, 1/43, 1/50, 1/64 or 1/87. These are often not exact; for example most diecast cars referred to as 1/64 scale are really just scaled down to approximately 3 inches to fit in the standard packaging. Unless the exact scale is specified on the model or its packaging just select the closest standard scale.

  16. Material: Choose the vehicle body's primary material. Select either "--Diecast Metal/Mazak" or "Plastic" as appropriate. There is no need to select both "Metal" and diecast metal.

  17. Color: List the primary paint color and paint type for the body. Example: A 1968 Redline release could include “Spectraflame” and “Red”. A newer car may have "Metallic" and "Red", or "Flat" and "Black". Unpainted cars are "ZAMAC".

  18. Decoration: Describe any decoration details such as a “Fire Dept.” decal, “Orange & Blue stripes on sides and hood”, "Detailed headlights and taillights", etc.

  19. Features: Add any additional features from the list. You can control-click (PC) or command-click (Mac) to select multiple features.

  20. Packaging Details: List any card or packaging variations such as “International Short Card”, “Snowflake Card” or different styles such as “2004 Style card” or “Red car on card artwork”.

  21. Reference #: Enter the collector number and the series number (if applicable). For consistency, these formats must be used (note the position of spaces, the # symbol, and commas): 
    1. The reference number for a mainline car with no segment series, such as the #714 Talbot Lago from 1997 would be entered as:
      Collector # 714

    2. The reference number for a mainline car that was part of a segment series, like the '49 Volkswagen Beetle Pickup from the 2020 Rod Squad series, would be entered as:
      Collector # 095/250, Series # 2/10

  22. Manufacturer ID: Enter the Mattel Toy Number from the packaging. Almost every Mattel product will have an alphanumeric Toy Number (SKU) and since the mid 1990s they always have five digits. They are also the best way to search a Mattel product on hobbyDB. For recent releases, the Toy Number can usually be found on the back of the card's J hook. Mattel Toy Number on the back of a Hot Wheels blister card
  23. UPC: Enter the 12 digit barcode number found on the package including the leading and trailing check digits and without spaces.

  24. Alternate UPC: Some recent Hot Wheels cars have been released in different assortments with different UPCs. If the only difference to the packaging is the UPC, add the second UPC to this field. If there are other differences (such as USA vs. International card) add it as a Subvariant.

  25. Description: Enter any other details about the car that aren’t covered above and or highlight what makes the car different from a normal release. Use complete sentences. Details already specified in database fields should not be repeated. If the model has a date code on the baseplate it can be entered here. Marketing copy from Mattel can also be entered here, but it should be clearly marked as such. Otherwise the description should be written in a neutral point of view.
