Feeling the Itch?  It’s UDI Season.

September typically marks new deadlines in the rollout of FDA’s Unique Device Identification (UDI) final rule.  That’s not the case this year – FDA’s next deadline doesn’t go into effect until 2018 – but we want to use the opportunity to provide a refresher. 

What is UDI?  It stands for Unique Device Identification.  A complete UDI contains two parts:

  1. “DI” – Device Identifier, such as a Global Trade Identification Number (GTIN)
  2. “PI” – Production Identifier, such as a lot code or expiration date

The complete UDI is printed onto each package label as both a barcode and human readable text.

Device Identifier

In order for companies to grow and expand, they must have the ability to communicate to new markets around the globe.   This is where the Global Trade Identification Number (GTIN) comes in.  GTIN is the global language that allows companies to effectively identify, capture, and share information automatically and accurately no matter who and where they are.  GTINs can be acquired through accredited issuing agencies such as GS1. 

How does it work?  First GS1 assigns a Company Prefix.  This prefix will allow businesses around the world to identify that company. Next, using GS1’s online portal, unique GTINs are obtained for all products under your scope.  Defining your scope and understanding what requires a GTIN vs. what doesn’t is of critical importance.  PCL specializes in helping companies with UDI implementation and can be a great resource to walk you through the considerations and ensure successful scope definition.

Production Identifier

This take can take many forms – essentially the Production Identifier “PI” is anything that creates a unique fingerprint for the production of the device, such as a lot number, expiration date, manufacture date, etc.  Good news is that medical device manufacturers are already doing this, so now it’s a matter of simply plugging that information into the UDI format.  GS1 accomplishes this by categorizing information into “application identifiers” (“AI”) which you can select from.  For example, expiration date is coded by the number (17) in parenthesis.  When the barcode shows (17) followed by [DATE] this means “expiration date”.

Verification

Once the barcode is created, verification & validation is the best way to ensure barcodes scan properly every time.  Verifying the content and quality of your labels saves time, productivity and money in the long run. PCL offers barcode grading as a service which can grade GS1 general specification codes and verify for print quality, quits zones, etc.

Bringing it All Together

UDI at its core is simple and powerful – GTINs combined with production identification numbers such as lot numbers, expiration dates, manufacturer dates, etc. uniquely identify your company and product around the world.  The use of barcodes allows labels to be scanned so the information stored can be easily and automatically accessed. The integration of scannable barcodes to access information increases the efficiency, productivity and customer satisfaction across the supply chain - inventory management and traceability, point of sale accuracy, regulatory compliance, shipping and receiving, and information sharing. 

Worried about UDI?  Don’t reach for the ointment, reach for the phone and call PCL today.  We specialize in helping companies’ setup, implement, and validate UDI compliant barcodes through both project management and testing.  We look forward to supporting your next project!
