Product identification
How to read an Oallstar product number.
Product numbers follow a consistent structure so buyers can identify the product family and distinguish individual catalog records.
Example only. The exact prefix is assigned according to the product category.
- 01Product family prefix
The letters at the beginning identify the product category or product family.
- 02Sequential product number
The numeric section uniquely identifies the individual product record within that family.
- 03Optional suffix
A suffix is used only when a product requires a clearly defined version, revision, or variant.
- 04Search the complete code
Enter the complete product number without extra spaces for the most precise catalog result.
Common questions
Before you submit an inquiry.
What information should I include with an RFQ?
Include the Oallstar code or OE number, vehicle or equipment information, required quantity, destination country, and clear product photos when available.
Can Oallstar confirm a part using only an OE number?
An OE number is a strong starting point. Final confirmation may also require technical specifications, connector details, dimensions, or vehicle application information.
How do I search a large list of cross-reference numbers?
Open the relevant product detail page and use the search field and producer filter inside the OE and reference number section.
What if the required product is not listed?
Send the available reference numbers and photos through the inquiry form. The request will be recorded for manual review.
