Unique device identifiers (UDI) are now a requirement for medical devices marketed in the US, and are being phased in by the EU and other countries. UDI systems are intended to benefit healthcare providers, manufacturers, authorized health authorities, hospitals and institutions, and individual consumers by providing:
UDI timeframes and deadlines vary by market and product, and have been revised multiple times in some countries. This article details the UDI deadlines for the countries which have announced specific programs, and is current as of the date of this article. Note that these dates can change as participating countries adjust their plans. We will continue to update this as more information becomes available.
There are two main components to UDI requirements, labeling and database registration. Despite efforts to harmonize both labeling and database requirements across markets, countries with UDI adoption plans have added market-specific requirements.

There are two components to a medical device UDI: the UDI device identifier (UDI-DI) and the UDI production identifier (UDI-PI). The UDI is presented as a barcode label (human and machine readable) on device packaging or on the device itself and acts as the access key to all device UDI attributes.
UDI-DI: This is the static portion of the UDI which identifies the manufacturer along with the specific device version. The UDI-DI (device identifier), also known as the Global Trade Item Number (GTIN) is assigned by an approved organization, such as GS1, and contains:
The UDI-DI is the primary identifier to be used in looking up device attributes in country-specific databases and is assigned prior to placing a product on the market. Note that the device identifier is different for different packaging levels of the same device.
UDI-PI: This is the dynamic portion of the UDI which is assigned by the manufacturer and identifies one or more of the following:
The UDI-PI actual values do not appear in country-specific databases (with the exception of the EU vigilance database).
Keeping track of country-specific UDI requirements, implementation timelines, and affected devices can be a big challenge to RA teams—especially because the information is scattered across many sources and hard to find. In this guide, we have consolidated timeline information and device class requirements across multiple countries. For additional country-specific details, check our Ultimate Guide to the EU MDR/IVDR UDI and the Ultimate Guide to the China NMPA UDI System.
The Australian Therapeutic Goods Administration (TGA) has set up a technical working group to define the specific UDI labeling and data requirements, with an expected date for the regulation in January, 2023. Mandatory compliance, however, will likely not go into effect until the following year. More details about the implementation timeline and progress of the project can be found on the Australian TGA website.
On January 10, 2022, RDC 591/2021, the regulation that requires UDI labeling and database registration for devices regulated by the Brazilian Health Regulatory Agency, ANVISA, came into effect. The regulation calls for rolling implementation based on risk class and the establishment of a Brazil UDI database. In the case of reusable devices for which the UDI information is placed directly on the product, an additional two years have been added to the transition periods below.
Details of the UDI database, and related compliance dates, are not yet available.
* Use of UDI labels became mandatory with this regulation in January, 2022 for coronary artery stents, drug-eluting coronary artery stents, and implants for hip and knee arthroplasty.

Health Canada has proposed a UDI framework based closely on the international UDI guidance from the IMDRF. The current proposal involves requiring UDI labeling for all devices, with the exception of Class I low-risk devices. Health Canada intends to either develop a UDI database or modify the existing Medical Devices Active License Listing database (MDALL) to accommodate UDI data. It is expected that, like most countries, Canada will add a small number of additional UDI data attributes to be required.
China’s current requirements include UDI labeling for the more complex devices, with additional device classes pending. In addition to labeling requirements, China requires that the UDI be recorded as part of a medical device registration.

UDI compliance deadlines have been delayed in the European Union, but the first UDI labeling deadlines have just passed. While 3 of the 6 EUDAMED database modules are currently available for voluntary use, EUDAMED registration is not being mandated until all 6 modules are fully functional. Mandatory compliance for UDI data entry into the EUDAMED UDI module is estimated to be mid-2026.
The first compliance deadline for UDI labeling was May 26, 2022 with the rest of the device classes rolling out through May 26, 2027.

At the end of 2021, the Indian Ministry of Health and Family Welfare delayed the implementation of UDI requirements in India and no new deadline has yet been put in place. Originally, Rule 46 of Medical Device Rule 2017 was set to require UDI labeling by January 1, 2022 for medical devices approved for manufacture, sale, distribution, or import in India. Details on how the UDI needs to be displayed on devices and the specific information that the UDI needs to include have not yet been released.
Japan was an early promoter of standardized barcodes, but is still working towards harmonizing their requirements with global UDI expectations.
Saudi Arabia has allowed voluntary UDI registration since October 1, 2020, but mandatory compliance for all device classes doesn't begin until September 1, 2022. These requirements apply to both labeling and database registration.
Medical devices imported before the compliance date can be distributed for up to 1 year after the compliance date without meeting UDI requirements. This exception does not apply to the Direct Marking (DM) requirement, which is a permanent marking of the UDI on the device itself.
All UDI Requirements:

Singapore is not currently requiring compliance with UDI labeling or database registration regulations. When requirements do go into effect, Singapore will accept UDI labels for devices already marketed in the U.S. and the EU, otherwise the UDI will need to comply with all of Singapore’s HSA guidelines, including partnering with an HSA-designated UDI issuing entity.
Singapore is also allowing companies a 6-month grace period for medical devices imported before the November deadlines listed below. So, for example, a company with a high-risk implantable device that requires UDI labeling and registration in November, 2022 would be allowed to continue to market devices that are not UDI compliant through May 1, 2023 (allowing local stock depletion prior to the compliance date).
For more information, see the Guidance on Medical Device UDI system from Singapore Health Sciences Authority.
South Korea has implemented UDI labeling and database registration requirements for most device classes, with just one class pending. As part of the introduction of UDI, South Korea has also mandated that manufacturers provide a device monthly supply history report, required 1 year from the UDI compliance dates.
Note that South Korean regulations refer to “Integrated Medical Device Information System,” or IMDIS, which is their UDI database and “Medical Device Standard Code,” which is the UDI code itself.
For more information, see the updated South Korean regulations:Guidelines for generating UDIs, Medical Device Act No. 14330 and the Regulation on KGMP No 2016-156 (links in Korean).
Taiwan has begun a phased implementation of UDI, which includes both labeling and database reporting requirements.
The United States is currently mandating compliance with both labeling and database requirements for all devices. The FDA does not intend to enforce the GUDID submission requirements for Class I and unclassified devices, other than implantable, life-supporting or life-sustaining devices (I/LS/LS), regardless of whether they are consumer health products, before December 8, 2022. Implantable, life-supporting or life-sustaining devices, including Class I I/LS/LS devices, are already expected to comply with GUDID submission requirements. The US FDA requires that all UDI information be entered into the US-specific GUDID database.
For additional information, see the FDA UDI system and requirements.
Each country has their own UDI database and varying requirements for the data stored in those databases. There is overlap in the data required among the various UDI databases, but each country also has unique data they require.
In addition, countries require that UDI-DI information be provided by “issuing entities.” Note that with the exception of China, all countries accept GS1, HIBCC, and ICCBA as issuing entities.
* Data attributes are approximations based on country UDI requirements and include mandatory, optional, mandatory if applicable, and country database auto generated elements.
** Expected to be similar to US GUDID requirements.
Our team recently discussed country-specific UDI requirements and strategies that regulatory affairs teams can use to better manage UDI data in an in-depth webinar. For additional information on UDI requirements, you can watch the webinar replay here.
