Mandatory QR Codes SUBTEL Resolution 737: Complete Guide 2025

Starting February 2026, all short-range devices commercialized in Chile must include a specific QR code on their packaging. This is one of the most significant innovations of SUBTEL Resolution 737. But what should this QR code contain? Where should it be located? What technical specifications must it meet?

With 21 years of experience in SUBTEL certification, at Certificación Telecom we are among the first to implement the compliant QR code system. In this guide we explain everything you need to know.

⚠️ Deadline: February 22, 2026

From this date, all WiFi, Bluetooth, Zigbee, RFID, and similar devices commercialized in Chile must have the mandatory QR code on their packaging. Without it, they cannot be legally sold.

Why mandatory QR codes?

Resolution 737 marks a radical change in how SUBTEL regulates short-range devices. Instead of the traditional certification process (which could take weeks or months), now importers declare conformity and provide all technical information via a QR code.

Benefits of the QR code system:

Which devices require mandatory QR code?

According to Resolution 737, the following short-range devices must include QR code:

✅ Important exception

Medical devices classified in sections (g) and (h) of Resolution 737 still require traditional SUBTEL certification and cannot use only the QR code system. These include implantable medical devices, vital monitors, and critical hospital equipment.

Technical specifications of the QR code

Not just any QR code is valid. SUBTEL establishes specific requirements you must meet:

Mandatory QR code specifications:

QR standard:
ISO/IEC 18004 (international standard QR Code)
Error correction level:
Minimum Level M (15% recovery) - Recommended Level Q (25%)
Minimum printed size:
2 cm x 2 cm (for small packages) - Recommended 3 cm x 3 cm
Contrast:
High contrast (black on white preferable, minimum 70% difference)
Quiet zone:
Minimum 4 modules margin around the code
Print resolution:
Minimum 300 DPI to guarantee reliable scanning
Location:
Outside of packaging, clearly visible, not obstructed
Durability:
Resistant during packaging lifespan (no removable stickers)

❌ Errors that invalidate your QR code

  • QR too small (less than 2 cm) - won't scan reliably
  • Low contrast (gray on white, light colors) - makes scanning difficult
  • No quiet zone (QR stuck to other elements) - causes read errors
  • Low-quality printing (less than 300 DPI) - blurry pixels
  • Removable or temporary sticker - SUBTEL may consider this as "no QR"

Mandatory content the QR code must contain

The QR code must link to a web page (URL) containing the following structured information:

1. Device information

2. Radiofrequency technical specifications

3. Responsible party information (importer/manufacturer)

4. Supporting technical documentation

5. Regulatory information

💡 Professional tip: At Certificación Telecom we create professional compliance pages, hosting included, with all this information structured according to SUBTEL specifications. Just send us your documentation and we generate your ready page + optimized QR code.

Where to place the QR code on packaging?

QR code placement is critical. SUBTEL can inspect at any point of sale, and if the QR is not accessible, the device is considered "without QR code."

Valid locations:

NOT valid locations:

📦 Design recommendation

Place the QR code on the back of the box, near importer information and technical specifications. Include text like:

"Complies with SUBTEL Resolution 737
Scan for technical information"

How to generate your compliant QR code

Generating the QR code technically is simple, but making it SUBTEL-compliant requires following specific steps:

Option 1: Do it yourself (advanced)

  1. Create your compliance page: Website with all required information (see list above)
  2. Get permanent URL: Stable domain (don't use temporary URLs or shorteners)
  3. Generate the QR code:
    • Use professional QR generator (qr-code-generator.com, qrcode.com, or libraries like qrcode.js)
    • Select error correction level: Q (25%) or higher
    • Generate in vector format (SVG, EPS) for scalable printing
    • Also export to PNG/JPG at minimum 1000x1000 px (300 DPI at final size)
  4. Validate the code: Test scanning with multiple devices (iPhone, Android, professional QR readers)
  5. Integrate in packaging design: Respecting size and quiet zone specifications
  6. Print test: Print sample and verify scanning before mass production

Option 2: Professional service (recommended)

At Certificación Telecom we offer complete service:

Delivery time: 3-5 business days with complete documentation.
Cost: From $300,000 CLP (includes page + QR + hosting for 1 year).

Common errors when implementing QR codes

1. Using URL shorteners (bit.ly, tinyurl, etc.)

Problem: SUBTEL requires permanent URLs. Shorteners can expire, change ownership, or be blocked.

Solution: Use your own domain with a clear URL: https://yourcompany.com/subtel/model-123

2. Compliance page without complete information

Problem: Creating a page with only basic data (brand, model) without technical supporting documentation.

Solution: Include ALL required information: RF specifications, declaration of conformity, responsible contact, downloadable PDF documents.

3. QR pointing to general corporate website

Problem: QR leading to "www.company.com" instead of device-specific page.

Solution: Each model must have its own specific URL with product technical information.

4. Not testing scanning before mass printing

Problem: Discovering the QR doesn't scan reliably after printing 10,000 boxes.

Solution: ALWAYS print a test sample and scan with multiple devices before mass production.

5. Forgetting to keep the page active

Problem: Domain expires, hosting expires, or page is accidentally deleted.

Solution: Configure automatic domain and hosting renewal. Monitor that URL remains active (uptime monitoring).

What happens if I don't include the QR code?

Starting February 22, 2026, commercializing short-range devices without the mandatory QR code is a serious violation of SUBTEL regulations.

Consequences:

⚠️ SUBTEL can inspect at any time

Inspections can occur at:

  • Points of sale (retail, physical stores, distributors)
  • Customs (at time of import)
  • Wholesale distributor warehouses
  • Through undercover purchases (mystery shopping)

Frequently asked questions about SUBTEL QR codes

Does the QR code completely replace traditional certification?

Yes, for most short-range devices (WiFi, Bluetooth, Zigbee, non-medical RFID). Only medical devices classified in sections (g) and (h) still require traditional SUBTEL certification.

Can I use the same QR for multiple models?

No. Each model or variant must have its own QR code pointing to specific information for that device. If only exterior color changes without RF changes, you can use the same QR mentioning variants on the page.

What happens if I update the device firmware?

If firmware only modifies application functionality (without changing RF parameters), you don't need to change the QR. If you change radiofrequency parameters, you must update the information on your compliance page.

Must the QR work without internet?

No. The QR points to an online URL, so the inspector will need internet connection to access the information. SUBTEL assumes inspectors will have connectivity.

Can I include the QR only on the device and not on the box?

It's not sufficient. The QR must be on the outer packaging to be accessible without opening the product. You can include an additional QR on the device as redundancy, but the packaging one is mandatory.

How long must I keep the QR page active?

While the device is in the Chilean market + at least 2 additional years for already sold devices. We recommend maintaining it permanently.
