| Step | What to do | Where to look |
|------|------------|---------------|
| 1. Check the packaging | Open the original box. The activation key is printed on a sticker or card that is included with the device. | Look for a label that says “Activation Key”, “Product Key”, “Serial No.” or “Kennwort”. It is usually a 12‑ to 16‑character alphanumeric string (e.g., AB12‑CD34‑EF56‑GH78). |
| 2. Inspect the router itself | Some models also carry the key on the hardware. | On the back or underside of the FRITZ!Box you will find a label that lists the Serial Number (S/N) and often the Activation Key next to it. |
| 3. Use the web interface after first‑time setup | If you have already powered the router on and connected it to a computer or smartphone, the key can be displayed in the wizard. | Open a browser and go to http://fritz.box (or the IP address shown on the device). During the initial setup wizard you will be prompted to enter the activation key. Click “Show key” or “Copy to clipboard” if the option is available. |
| 4. Check the documentation that came with the box | The quick‑start guide or printed manual often repeats the key for easy reference. | Look for a page titled “Activation / Registration” or similar. |
| 5. Retrieve it from your AVM account | If you registered the router when you first set it up, the key is stored in your online profile. | Log in to the AVM portal at https://my.avm.de → My Devices → select your FRITZ!Box model → Activation Key will be shown (you may need to verify your identity). |
| 6. Contact AVM support | If the key cannot be located (e.g., lost packaging, damaged label), AVM can verify your device and provide a replacement key. | Use the AVM support form or call the AVM hotline. Have the Serial Number and proof of purchase handy. |

| Mistake | Why it’s a problem | How to fix it | |---------|-------------------|---------------| | Typing the Serial Number instead of the Activation Key | The two strings look similar but are not interchangeable. | Verify you are using the 12‑/16‑character key that includes hyphens. | | Using a key from a different FRITZ!Box model | Keys are model‑specific; a key from a 7590 won’t work on a 7530. | Double‑check the model printed on the router or box. | | Entering the key with extra spaces or line breaks | The web wizard treats spaces as invalid characters. | Copy‑paste directly from the label or type carefully, avoiding extra whitespace. | | Trying to use a key that has already been registered on another account | The key can only be linked to a single AVM account. | Log in with the account that originally registered the device, or request a new key from AVM support. | | Step | What to do | Where
