Scaling app marketing campaigns with bulk QR code generation

QR codes have become a core part of cross-platform marketing strategies. They serve as an incredibly effective tool in bridging the gap between offline, desktop, connected TV (CTV), and mobile: giving users a seamless way to transition between devices. For brands, QR codes have developed from a “nice-to-have” to an important component in creating smooth user journeys, unlocking key use-cases like offline-to-app, desktop-to-app, CTV-to-app, and more.

An effective QR code must embed not just analytics and campaign data, but also deep linking information that brings the user directly to the relevant in-app content. This ensures users don’t get stranded on an app homepage, but land exactly where they expect (a product page, loyalty program, exclusive in-app promotion, etc.), picking up their journey without friction.

Users that are already visiting a brand’s offline stores, or consuming the brand’s content on other devices like PCs or CTVs, exhibit strong signals of awareness and intent. They are prime candidates to be nudged to the mobile app.

For marketers running campaigns across multiple channels, stores, or even entire retail networks, QR codes can quickly become a challenge of scale. Imagine a nationwide rollout where each store location needs its own code, each salesperson has a unique identifier, and every campaign placement requires a custom link. Without the right infrastructure, managing this volume is slow, resource-intensive, and overly dependent on developers.

And scale without measurement is difficult, or even impossible, to tie to real outcomes. To truly understand the impact of QR-driven campaigns, marketers need visibility into performance at every level—campaign, store, salesperson, channel, and more. That’s what transforms QR codes from a tactical tool into a strategic growth driver, but the right infrastructure is critical. 

With Adjust’s bulk QR code generation tools, marketers can produce thousands of branded QR codes (embedded with deep links) quickly and without developer support. Campaign managers simply upload a spreadsheet of details, and Adjust automatically generates unique codes tailored to each use case—whether for in-store signage, out-of-home placements, or CTV ads.

Every code comes with customizable design options to match brand identity, plus embedded attribution data for real-time performance tracking. Deep linking ensures users land in the right place in-app, while measurement and reporting provide insight into scans, installs, and post-install events. At scale, this makes QR campaigns not just easier to launch, but smarter to optimize.

Each QR code also has a short link under the hood, which enables dynamic updates of any underlying link data/parameters without modifying the short link/QR code. This means that campaign data, redirection, and deep link routing can be modified without needing to rip-and-replace the QR code. Print and distribute once, then repurpose them as much as you need!

Here’s what’s possible:

• Spreadsheet bulk generator: Empowers non-technical marketers to create thousands of QR codes at once without developer involvement. By filling out campaign details in a spreadsheet, Adjust’s script automatically packages links and produces branded QR codes. Suitable for use cases like offline-to-app. 
• QR code API: Flexible API that allows developers to create customized QR codes in near real-time. Suitable for use cases like desktop web-to-app.
• Deep linking integration: Each Adjust QR code is powered by our advanced TrueLink functionality, which ensures that users landing in the app are directed to the correct page.
• Customization options: Marketers can define QR code size, style, margins, borders, and background colors to match brand identity and improve user trust and scan-through rates.
• Full measurement & attribution: Campaign-level and store-level insights enable optimization, incentivization, and real-time adjustments across locations.

Aditya Birla Fashion and Retail Limited is a leading Indian fashion retail company. By using Adjust’s bulk QR code generator for their Pantaloons brand, they scaled offline-to-app campaigns across hundreds of retail stores nationwide. Each store received its own unique, branded QR code, tied to its store ID and location. The results included:

• Store-level reporting to optimize locally while tracking national impact
• Empowered retail personnel who could actively drive app adoption
• Consistent branded QR codes across thousands of touchpoints

The increasing prominence and utility of QR codes reflects a shift in how users expect to interact with brands across devices. For marketers, they are no longer just a way to connect offline to online, but a strategic lever for growth, personalization, and measurement.

With the right infrastructure in place, QR codes unlock seamless user journeys across platforms, scalable acquisition opportunities, and granular insights to fuel campaign optimization.

For mobile app businesses, the ability to generate, customize, and measure QR codes at scale is now a competitive advantage, and automation via Adjust makes it possible.
