GTIN Check API
On-demand barcode and GTIN validation using GS1's official GTIN Check service—built into the PartLogic platform and available for teams that need programmatic access alongside portal workflows.
Built for real-world product data workflows
Teams no longer need to stitch together spreadsheets, scanners, and ERP screens for a standards-backed check. Use GTIN validation in the portal when adding parts, or integrate lookups into the tools you already run.
Ad-hoc lookups
Send a barcode or GTIN whenever you need a check—ideal for receiving desks, data stewards, and one-off investigations.
Authoritative validation
Responses are sourced via GS1’s official GTIN Check service so you can trust the result when reconciling product records.
In the platform and via API
Use GTIN check inside the PartLogic portal when onboarding parts, or call the API from scripts, middleware, and line-of-business apps.
Structured product signals
Use validated identity and related product information to reduce mismatches, duplicates, and bad master data.
Who it is for
If you already invest in clean identifiers, GTIN Check meets you where you work—in the portal, in code, and in day-to-day operational checks.
Engineering & data teams
Wire lookups into ETL jobs, microservices, and internal portals with the same validation your catalogue stewards use in the portal.
Operations & supply chain
Give receiving, quality, and catalogue teams a consistent way to confirm a GTIN before it enters your systems of record.
Get started
GTIN check is available in the PartLogic customer portal when you validate barcodes during part creation and classification. For API access, create an integration key in the portal and follow the developer guides for authentication and endpoints.
