Custom Domains

By default, Qrius QR codes redirect through a short URL like qrslnk.com/abc123. But what if you want your brand on the redirect?

Custom domains let you use your own domain — like scan.mycompany.com — instead of our default. Your QR codes still work exactly the same way, but the redirect URL carries your branding.

What Custom Domains Do

When someone scans a QR code, they’re actually scanning a short link that redirects to your destination. With a custom domain, that short link uses your domain instead of ours.

Without custom domain:

• QR encodes: qrslnk.com/xyz789
• User scans → gets redirected → reaches your destination

With custom domain:

• QR encodes: scan.mycompany.com/xyz789
• User scans → gets redirected → reaches your destination

The experience is identical. But if a user checks their browser address bar, they see your domain, not ours. It feels more professional and builds trust.

Setting Up a Custom Domain

Step 1: Add Your Domain

1. Go to Settings → Domains tab
2. Click Add Custom Domain
3. Enter your domain (e.g., scan.mycompany.com)
4. Click Next

Step 2: Verify DNS

Qrius will show you a DNS CNAME record to add. It looks like:

Name: scan
Type: CNAME
Value: cname.vercel-dns.com

Go to your domain registrar (GoDaddy, Namecheap, AWS Route 53, etc.) and add this CNAME record.

Important: You need DNS access for your domain. If you don’t have it, ask your IT team.

Step 3: Verification & Activation

1. Return to Qrius and click Verify Domain
2. Qrius checks your DNS records
3. Once verified, the domain is active immediately

DNS propagation can take a few minutes to a few hours globally. Until then, some scans might still hit the old default domain. That’s normal — be patient.

Managing Your Domains

On the Domains page, you can:

• View all domains — see which ones are verified and active
• Edit domain — change which domain is your primary
• Delete domain — remove a domain (unverified domains can be deleted instantly)

When you delete a domain, QR codes that used it will fall back to the default domain. Existing scans aren’t affected — the redirect still works.

Best Practices

1. Use a subdomain — scan.mycompany.com is better than pointing your root mycompany.com to Qrius
2. Keep it short — scan.co or go.mycompany.com are memorable
3. Use one primary domain — don’t bounce between multiple domains in your campaigns; pick one and stick with it
4. Verify before launching — test a few QR codes after verification before running a big campaign
5. Document your setup — keep track of which domain is for which campaign (especially if you have multiple organizations)

How It Affects Existing QR Codes

When you add a custom domain:

• New QR codes use your custom domain by default
• Existing QR codes keep their old short URL (they still work fine; nothing breaks)
• Optional update — if you want old codes to use your new domain, you can regenerate them (they’ll get new short codes)

So adding a domain is non-destructive. Your old campaigns keep working.

Troubleshooting

“Domain verification failed”

• Double-check your CNAME record in your DNS provider
• Wait a few minutes — DNS can take time to propagate
• Make sure you’re pointing the right subdomain (e.g., scan, not scan.mycompany.com)

“My QR codes still use the old domain”

• Existing codes keep their old URLs (that’s by design)
• New codes you create will use your custom domain
• If you really need old codes on the new domain, regenerate them (they’ll get new short codes)

“I don’t have DNS access”

• Ask your IT or web team to add the CNAME record
• Some registrars (like Shopify or Wix) manage DNS for you

“I want to remove the custom domain”

• Delete it from the Domains page
• QR codes fall back to the default domain
• Existing scans still work
