PARKnSHOP Sees Multiple Benefits from Verified by GS1


Replacing one-at-a-time manual GS1 GTIN checks with batch-sized automation through Verified by GS1 allowed PARKnSHOP to reduce the time needed to list products.


PARKnSHOP is Hong Kong’s leading supermarket chain and one of the most trusted brands in Hong Kong. Part of the A.S. Watson Group, PARKnSHOP has about 260 physical outlets in Hong Kong and Macau as well as a thriving e-commerce market.

“We provide a wide range of products for our customers to purchase both online and in our stores,” explains Garrick Chan, PARKnSHOP Supply Chain Director, “and we frequently update and refresh our product range, in order to ensure that our customers stay excited.”

PARKnSHOP believes in the GS1 GTIN and understands well the efficiencies of the GS1 system of standards. The company has long-established control points to make sure every product’s GS1 GTIN is validated before it is listed.


As part of their commitment to provide accurate product listings, PARKnSHOP’s supply chain team previously checked each new product’s GS1 Global Trade Item Number® (GTIN®) manually.


PARKnSHOP now queries batches of GS1 GTINs in Verified by GS1 and instantly gets feedback for all items items.


PARKnSHOP’s product listing process is efficient and streamlined. What used to take days, now only takes a few hours.

Accurate GTINs help us ensure that our supply chain flow is error-free, whether in catalogue planning, planogram design, ordering, supplier delivery to our warehouse and to retail shops—and even for our customers.

Verified by GS1 for PARKnSHOP


Manual processes


For years, PARKnSHOP staff manually checked every GS1 GTIN one by one: an obviously time-consuming and inefficient method that limits the quantity of GS1 GTINs that can be processed on any given day.

So, in February 2021, when GS1 Hong Kong introduced Verified by GS1 to PARKnSHOP, the retailer was immediately interested: “We were very keen to grasp this opportunity to improve our business,” says Garrick Chan.

Being an early adopter of Verified by GS1 was also completely in line with the A.S. Watson Group’s commitment to support The Consumer Goods Forum, as they work to empower the digital transformation with accurate and better product information.

Benefits quickly visible

PARKnSHOP’s GS1 GTIN validation process for a batch of new items now only takes hours instead of days. “Within a few months of implementing Verified by GS1,” says Garrick Chan, “our product listing processes were streamlined. We can query a big batch of barcodes in the system and instantly get back the feedback for all items—all in one go, without limitation on the number of GS1 GTINs.”

Thanks to Verified by GS1, PARKnSHOP can reinvest their resources into other tasks and projects that bring more value to their business. They are also avoiding the bottlenecks they used to face whenever they want to add a large set of new items to their product listings.

Less than a year after going live with Verified by GS1, Garrick Chan and his team are fully convinced by its benefits and value: “Having accurate product information flowing along our supply chain has helped us achieve efficiency.”

Information they can trust

Another benefit the retailer has found in using Verified by GS1: access to a single source of trusted information. PARKnSHOP is increasingly selling products that come from all over the world. Because Verified by GS1 is linked to the GS1 Registry Platform, the company can check the GS1 GTINs of all of their products, no matter where they were sourced.

Better online experiences

Garrick Chan notes that using Verified by GS1 also enhances the experience of their online shoppers.

Since nowadays many customers shop online—where they cannot physically see or touch a product—accurate and complete product information has become an extremely important part of the purchasing decision.

With Verified by GS1 connecting them directly to information provided by brand owners themselves, PARKnSHOP can get trusted and up-to-date product descriptions, images and more into their listings of product master data and then onto the web pages of their online shop.

“It’s not only about efficiency and speed,” Garrick Chan says, “it’s also about accuracy and alleviating the legal risk of incorrect product information.”

“At PARKnSHOP, we believe in GS1 global standards. Only through a collaborative effort from brand owners, retailers and e-tailers can we build a reliable and trusted commerce ecosystem around the world.”
