YQ Service is an automotive data platform specialized in accurately identifying replacement parts starting from a vehicle's VIN code. The company, YQ Service s.r.o., is headquartered in Košice, Slovakia, and combines original equipment (OE) part data with aftermarket data in a single automotive components identification system, which we will refer to in this article as an ACIS system.
For a distributor, a repair shop, or an online store, the practical difference is simple: instead of manually searching for the right part by make and model, you enter the vehicle's VIN, and the system returns exactly the parts compatible with that specific car. That reduces compatibility errors and wrong orders.
Below we explain what YQ Service is, how VIN-based search works, who benefits from this type of system, and how it fits into a complete auto parts catalog alongside TecDoc.
What YQ Service Is, In Practice
YQ Service s.r.o. is a Slovak company that specializes in providing automotive technical data for identifying replacement parts. According to the official website yqservice.eu, the platform covers more than 100 million VIN numbers and 67 passenger and commercial vehicle brands, with access to more than 10 million technical drawings sourced directly from manufacturers.
The company is a member of the Automotive Data Publishers Association (ADPA) and, according to the same source, is used by more than 250 companies across 34 countries, processing around 11.5 million VIN searches per month. Among the companies using YQ Service data, the official website names EUROPART, Intercars, and DENSO.
In practice, YQ Service does not sell parts directly to end consumers. It is a data provider and identification system that distributors, parts manufacturers, and online stores integrate into their own platforms, in order to offer precise vehicle-based search.
What the ACIS System Is and How It Combines OE and Aftermarket Parts
ACIS is the term used to describe an automotive components information system that brings together, in a single queryable database, two types of parts:
- OE (Original Equipment) parts — parts identical to the ones installed at the factory on the vehicle, produced by or for the original vehicle manufacturer.
- Aftermarket parts — compatible parts manufactured by companies other than the original manufacturer, validated as a replacement for the OE part.
The difference matters to the buyer: OE parts generally guarantee an exact match with the original vehicle, while aftermarket parts often offer a lower price, with compatibility confirmed technically, not just estimated from make and model.
An ACIS-type system doesn't force the store to choose between the two categories. Its role is to display, for each part searched, both the OE option and the available aftermarket alternatives, so the end customer or the repair shop can decide with full information.
What a VIN Is and What Information It Contains
A VIN (Vehicle Identification Number) is the unique identification code of a vehicle, made up of 17 alphanumeric characters. Every manufactured vehicle has its own VIN, which is never repeated.
Precise technical information about the vehicle can be extracted from the VIN structure, including:
- Manufacturer and country of production.
- Model, generation, and body type.
- Year of manufacture.
- Engine type and, in many cases, factory-specific equipment.
This precision is why VIN-based search eliminates the compatibility errors that often occur when a buyer selects parts based only on make and model — two seemingly identical cars can have different engines or factory equipment, and therefore different parts.
How VIN-Based Auto Parts Search Works With YQ Service
In practical terms, the VIN search process through a system like YQ Service generally follows the same steps, whether the user is an end customer on an online store or an operator in a parts warehouse:
- The user enters the vehicle's 17-character VIN code.
- The system decodes the VIN and identifies the exact vehicle: make, model, generation, engine, year of manufacture.
- Based on the manufacturer's original technical drawings, the system displays the part categories available for that vehicle (brakes, filters, suspension, body parts, etc.).
- For each category, the user sees both the original OE part and the compatible aftermarket alternatives.
- The selected part is added to the cart or sent directly to the order, with the correct code.
Besides VIN search, according to publicly available information on yqservice.eu, the platform also supports search by vehicle model, by the part's OEM number, or by license plate number, for cases where the VIN is not immediately available.
Search Methods Available in an ACIS System
| Search Method | When It's Used | Precision Level |
|---|---|---|
| VIN code | Customer has the vehicle's registration or VIN on hand | High — exact parts for that vehicle |
| Make + model + engine | Customer doesn't have the VIN available | Medium — needs further confirmation |
| Part OEM number | Customer already knows the old part's code | High, if the old part was the original one |
| License plate number | Quick alternative to VIN, where available | High, depending on database accuracy |
Who Uses YQ Service: Distributors, Repair Shops, and Online Stores
ACIS-type systems, such as the one offered by YQ Service, are relevant to several types of users in the automotive industry:
- Spare parts distributors — order compatible parts quickly, reduce procurement errors, and optimize inventory management.
- Repair shops — quickly identify the part needed for a vehicle on the lift, without manual searches through printed catalogs or separate websites.
- Online auto parts stores — offer customers VIN-based search directly on the site, with automatic recommendation of compatible parts.
- Vehicle and parts manufacturers — can provide more accurate technical support and compatibility information to customers and partners.
For an online store, integrating VIN-based search means, in practice, fewer returns caused by incorrectly ordered parts and a shorter time to complete an order.
YQ Service and TecDoc: Complementary Systems, Not Alternatives
YQ Service and TecDoc are not solutions between which a store has to pick just one. YQ Service mainly covers OE parts, with data sourced directly from manufacturers' technical drawings, while TecDoc is the best-known aftermarket parts catalog in Europe. A store that wants a complete catalog — original and aftermarket parts, for the same category of need — needs both data sources in practice.
If you want technical details about integrating the TecDoc aftermarket catalog, including VIN-based part identification through the TecDoc API, you can read the technical guide on VIN search with the TecDoc API.
Case Study: YQ Service Integration for an Original Parts Store
HappyWeb built stoauto.ro, an online store for original auto parts, with yqservice.eu data integration. The project includes a catalog module for original auto parts, product-to-vehicle association by make, model, and engine type, a "garage" feature for saving the customer's vehicles, price list import, and integration with standard ecommerce modules (cart, customer account, order management).
You can see the full project details on the stoauto.ro portfolio page.
Frequently Asked Questions About YQ Service and VIN Search
1. Is YQ Service an online store or a data provider?
YQ Service is an automotive technical data provider. The company does not sell parts directly to end consumers; instead, it provides identification data (including VIN-based search) that distributors, repair shops, and online stores integrate into their own platforms.
2. What's the practical difference between OE and aftermarket parts?
OE parts are identical to the ones installed at the factory on the vehicle. Aftermarket parts are manufactured by other companies, but technically validated as a compatible replacement, usually at a lower price.
3. What if I don't have the vehicle's VIN on hand?
You can search by make, model, and engine, by the old part's OEM number, or, where available, by license plate number. Accuracy is generally higher with the VIN, since it removes ambiguity between engine or equipment variants.
4. Can YQ Service be integrated alongside TecDoc in the same store?
Yes. They are complementary systems — YQ Service covers OE parts, TecDoc covers aftermarket parts — and they can be integrated together for a complete auto parts catalog.
Conclusion
YQ Service is an automotive data platform from Slovakia, specialized in accurately identifying replacement parts starting from a vehicle's VIN code, by combining OE data with aftermarket parts in a unified system. For distributors, repair shops, and online stores, the practical benefit is direct: fewer compatibility errors and a faster ordering process.
HappyWeb has already implemented this type of integration for an original auto parts store (stoauto.ro) and can do the same for your store, including in combination with a TecDoc aftermarket catalog.
