UID Labels and Nameplates

About UID and IUID Marking

Unique Identification (UID) and Item Unique Identification (IUID) are part of the identification marking process mandated by the United States Department of Defense (DoD). UID and IUID are permanent marking methods used to give military property and Government-Furnished Property (GFP) a Unique Item Identification (UII).

UID and IUID marking is a systematic process to globally and unambiguous distinguish property and ensure data integrity throughout an item’s lifecycle through the use of two-dimensional (2D) Data Matrix ECC 200 Symbols.

UID and IUID marking is required for all military property and equipment with an acquisition cost over $5,000, equipment that is mission essential, controlled inventory, or serially-controlled.

UID Construct 1 Components

  • Issuing Agency Code
  • Enterprise Identifier
  • Serial Number unique within the Enterprise

UID Construct 2 Components

  • Issuing Agency Code
  • Enterprise Identifier
  • Part Number
  • Serial Number (unique within the Part Number)

Labeling is required for DoD vendors. Express UID and IUID nameplates satisfy the following DoD standards and specifications:

  • MIL-STD-130 – this standard specifies the marking requirements and methods for identification of military property produced, stocked, stored, or issued by or for the DoD. This standard further provides information for the implementation of machine-readable information (MRI) processes for item identification marking and facilitating automatic data capture.
  • MIL-STD-13231 – this standard specifies the DoD’s uniform marking requirements for electronic items.

This includes chromic acid anodizing, non-chromic acid anodizing, sulfuric acid anodizing, and hard anodic coatings.

The label looks amazing.  Thank you for taking the time to meet our requirements and provide the sample labels quickly.  My manager was impressed with how quickly you provided a sample via email.  We look forward to working with you to meet our asset tag needs.

When looking for a new vendor for labels, I reached to to Express and they were very knowledgeable and helpful. After waiting for days from a large company, these guys had fast turnarounds for quotes, and the pricing was better than the mighty conglomerate that had me waiting.
Evan was very helpful and always available when I had a question. Great service you guys!

I have to say you are all so easy to deal with at Express, it really is a pleasure doing business with you!!!

I just wanted to let you know that the labels arrived in a timely manner and they looked great! I just wanted to express my thanks to you for the outstanding job that you did in making things happen in such a short window.

Robert H.

Requested a quote for product information and pricing and received a response the same day. Not too often that same day responses are provided from vendors, especially for the type of request that was put through. Good stuff and will keep in the file for a Go-To company.

Thank you so much for processing our ID plates so quickly and getting them shipped earlier than projected!  I am sincerely grateful for your efforts with this and providing us the items in a timely manner.  Looking forward to doing business again in the near future.

I just want to say how nice they [the tags] look, how well they were packaged, how appreciative I am that you got them to us in time and communicated with me during this order.  Thank you so much!

Linda G.

We will let you know if we ever need anything else.  Ya’ll have been great!

Jennifer D.

I am impressed! Thanks for the fast service.

Jason D.

We got the labels and everyone here really likes the quality and appearance of them.  I’m working on another order for you of the UID labels and will have that data out next week.  Thanks!

Greg H.

We are extremely pleased with our order.  You blew us away with your quick, reliable service and will be our only source for UIDs in the future.

David W.

We have used Express a number of times and the quality and service CANNOT be beat! Everyone works hard to ensure your order is correct and on time (if not early)! I cannot say enough good things about them!
