Bulk batch code verification for inventory teams

Upload a CSV or paste multiple batch codes to check them simultaneously. The system cross-references against its database of over 50,000 brands to return production dates and estimated shelf life. This eliminates the need to visit individual brand websites or third-party databases.

Business outcome: Reduces manual verification time from hours to minutes for large inventory checks.

API integration for automated supply chain workflows

Connect Cosr.ai directly to your inventory management or ERP system via a REST API. This enables real-time batch code checks as products are scanned into your warehouse, flagging expired or soon-to-expire items automatically.

Business outcome: Enables automated compliance checks without manual data entry, reducing human error.

Extensive database of global cosmetic brands

Coverage spans luxury, mass-market, and indie brands across regions including Europe, North America, and Asia. The database updates regularly as new brands and batch code formats are added by the community and internal research.

Business outcome: Minimises the risk of unrecognised batch codes, especially for international stock.

Accurate production date and shelf life calculation

Each batch code is decoded to show the exact manufacturing date and the remaining shelf life based on product category. The tool accounts for different regional date formats and manufacturer-specific coding schemes.

Business outcome: Provides clear expiry information for inventory rotation and customer communication.

Searchable history of all batch code lookups

Every lookup is stored in a searchable log, allowing teams to revisit past checks, export reports, and audit their verification history. This is critical for compliance documentation and dispute resolution.

Business outcome: Creates an auditable trail for regulatory inspections and internal quality control.

Mobile-friendly interface for on-the-go scanning

Access the tool from any mobile browser to scan batch codes directly from product packaging. The interface is optimised for quick single lookups, making it useful for retail staff on the shop floor or consumers in-store.

Business outcome: Enables instant verification at point of sale or receipt, improving customer trust.

• Broad brand databaseCovers over 50,000 brands, reducing the chance of encountering an unrecognised batch code.
• Bulk verification efficiencyBatch uploads and API integration make it practical for inventory-level checks, not just single lookups.
• Clear date outputReturns both production date and remaining shelf life in a simple, readable format.
• Audit trail for complianceThe history log provides a verifiable record of all checks, supporting regulatory requirements.

• Incomplete brand coverageSome newer or very niche brands may not be in the database, requiring manual fallback checks.
• No counterfeiting guaranteeA valid batch code does not prove the product itself is authentic — only that the code matches a known format.
• Limited to cosmeticsThe tool does not support batch codes for pharmaceuticals, food, or other regulated product categories.
• Professional RealityCosr.ai is a practical lookup tool, but it relies entirely on its database accuracy — if a brand changes its coding system, results may be incorrect until the database updates.

Retail inventory auditing

A beauty retailer receives a pallet of 200 different SKUs. Using Cosr.ai's batch upload, the team checks all codes in under a minute, identifying 12 products that are already expired and 30 that will expire within three months. This prevents customer complaints and regulatory fines.

Consumer pre-purchase check

A shopper finds a discounted lipstick at a market stall. They use the free Cosr.ai single lookup to check the batch code, discovering the product was manufactured four years ago and is likely expired. They avoid the purchase.

Import compliance verification

An importer of Korean skincare products uses the API to automatically verify batch codes on every shipment before clearing customs. The system flags any codes that do not match expected formats, prompting further investigation.

Second-hand marketplace listing

A reseller on a platform like eBay or Depop uses Cosr.ai to verify the batch codes on luxury cosmetics before listing them. This builds buyer trust and reduces the risk of disputes over product age.

Go to cosr.ai and enter a single batch code in the search bar to test the free lookup.
