You’d think this would be the easiest part of pet tag shopping: just put your name and number on it, right? Done. Except — what if you have two phone numbers? What about your vet? What if your pet has a medication they need every day? What if a stranger finds them at 11pm on a Sunday and doesn’t know what to do?
The information you put on (and behind) your pet’s tag is the difference between a “found pet” story that ends in a heartwarming reunion and one that drags on for days. Here’s the complete guide to what actually belongs on your pet’s ID — and why smart tags let you include far more than the engraving alone allows.
The Two Layers of Pet Tag Info
Modern smart tags actually carry two separate layers of information:
- Engraved on the surface — what someone reads instantly, no scan required
- Stored in the digital profile — what someone sees when they tap their phone to the tag
The engraved layer is your “minimum viable info” — what every finder gets right away. The digital layer is your “everything else” — the depth that turns a frantic finder into a calm Good Samaritan who knows exactly what to do.
What to Engrave on the Tag’s Surface
Keep this short and high-contrast — there isn’t much real estate, and you want the most important info legible from a distance.
Must-Haves
- Your pet’s first name — calms them, helps the finder talk to them
- One phone number — the most reliable way to reach you
- “Tap for info” or NFC symbol — signals there’s more to read
Optional but Helpful
- “Microchipped” if applicable — vets and shelters notice this
- “Reward” if you’d offer one (it motivates strangers to act fast)
- City/zip code if there’s room
What to Skip
- Your home address — too much detail for a stranger to have
- Long full names — first name is enough
- Email addresses — phone is faster in an emergency
What to Put in the Digital Profile
This is where smart tags shine. The profile can hold as much as you want, organized in a way that helps the finder act quickly. Here’s what to include:
Contact Information
- Primary owner name and phone
- Secondary owner / spouse / partner phone
- One out-of-town emergency contact (in case you’re traveling)
- Best email for non-urgent communication
Veterinary Information
- Vet practice name and phone number
- Pet’s microchip number
- Any pre-authorization notes (“treat as needed, I’ll cover costs”)
Medical Information
- Medications and dosing
- Allergies (food, medication, environmental)
- Chronic conditions (diabetes, epilepsy, hip dysplasia)
- Recent surgeries or injuries
Behavioral Notes
- How your pet reacts to strangers (friendly, shy, fear-bites)
- Triggers (sudden movement, loud sounds, men with hats)
- What calms them (their name, treats, a specific phrase)
- Whether they’re house-trained
The Voice Greeting
If your tag supports it (Shiloh’s House tags do), record a short voice message. Keep it warm, short, and practical:
“Hi! I’m Heather, Shiloh’s mom. Thank you so much for finding her. Please call or text me at the number on this profile and I’ll come get her right away. There’s a treat in this for you, I promise.”
Voice greetings dramatically increase the rate at which finders wait with your pet rather than dropping them at a shelter or driving off.
What NOT to Include
Just as important as what to put in is what to keep out. Skip:
- Your home address — first responders can find it via your phone, but a random stranger doesn’t need it
- Social Security numbers, account numbers, or anything financial — never relevant
- Photos of your kids alongside the pet — not relevant, and a privacy issue
- Anything overly cute or jokey that overshadows the practical info
- Long backstories — keep it scannable, not a novel
How Often to Update
Most pet parents set up their tag once and never touch it again. Bad idea. Set a calendar reminder to review the profile every 6 months and update whenever:
- You move or change phone numbers
- You switch vets
- Your pet’s medication or medical needs change
- An emergency contact changes
- You travel for an extended period (add a temporary contact)
The whole point of a smart tag is that the data stays current — but only if you actually keep it current.
Putting It All Together
Here’s the simple rule: the engraving covers the basics so a finder doesn’t need to scan to start helping. The smart profile covers everything else so a finder has the full picture once they do scan. Layered together, your pet has the most informed first responders possible — even if those first responders are total strangers.
