Losing a pet is every owner's worst nightmare. You're probably here because you want to make sure your dog or cat can find their way back home if they ever get lost. Two of the biggest names in pet microchip registration are PetKey and Home Again, but which one actually works better?
I've spent hours digging into both services to give you the real deal. No fancy marketing talk, just straight facts about what each company offers and which one might be the better choice for your pet. Let's jump right in.
Key Takeaways
- PetKey offers completely free lifetime registration with no annual fees
- Home Again charges annual fees but includes extra services like lost pet specialists
- Both microchips work with universal scanners used by vets and shelters
- PetKey focuses on basic recovery services, while Home Again bundles additional benefits
- Your choice depends on whether you want free basic protection or paid premium features
- Either option is way better than no microchip at all
What is PetKey?
PetKey is a pet recovery service that started back in 1998. They made a pretty bold move by offering completely free microchip registration for life. Yep, you read that right - no annual fees, no hidden costs.
The company runs a 24/7 call center and maintains a massive database of registered pets. When someone finds your lost pet and a vet or shelter scans the microchip, they can look up your contact information in PetKey's system and get your furry friend back to you.
PetKey partners with various microchip manufacturers, so their service works with multiple chip brands. This makes it super convenient since you don't need a specific chip brand to use their registry.
What is Home Again?
Home Again launched in 1995 and quickly became one of the most recognized names in pet recovery. They're owned by Merck Animal Health, which is a huge company in the veterinary world.
Unlike PetKey, Home Again charges an annual membership fee (usually around $19.99 per year). But they argue this fee pays for extra services that free registries don't provide.
Home Again has registered over 10 million pets and claims to reunite a pet with their owner every few minutes. Their microchips are ISO-compliant, meaning they meet international standards and can be read by most modern scanners.

Recovery Success Rates
Both companies claim high success rates, but exact numbers are tricky to verify.
Home Again publishes statistics showing they reunite pets with owners regularly. They emphasize their "lost pet specialists" who actively help with recovery efforts.
PetKey doesn't publish as many statistics, but their free service has successfully reunited thousands of pets with their families. The basic recovery system works just fine for most situations.
Here's the thing though - having any microchip registry is way more important than which specific one you choose. Most lost pets get reunited because someone found them and got them scanned, not because of fancy extra services.
Technology and Scanner Compatibility
Both services use ISO-standard 134.2 kHz microchips. This is the frequency that almost every vet clinic and animal shelter in the United States can scan.
PetKey microchips:
- Universal scanner compatible
- 15-digit identification number
- Works with multiple chip manufacturers
- No proprietary technology required
Home Again microchips:
- Universal scanner compatible
- Bio-Thermo technology in some chips (detects body temperature)
- 15-digit identification number
- Widely recognized brand
The scanner compatibility is basically identical. Any standard pet scanner will read either chip without problems.
Customer Support Quality
PetKey Support:
- 24/7 phone line
- Email support
- Basic online resources
- Response times vary
- Focused on recovery assistance
Home Again Support:
- 24/7 phone line with dedicated specialists

- Comprehensive online resources
- Generally faster response times
- Proactive lost pet assistance
- Access to vet advice hotline (with membership)
Home Again puts more resources into customer support. According to big write hook, this kind of dedicated support infrastructure can make a difference in stressful situations.
Database and Registration Management
PetKey:
- Free unlimited updates to your contact information
- Simple online portal
- Easy to transfer ownership
- No expiration warnings needed (because there's no expiration)
Home Again:
- Unlimited contact updates with active membership
- More sophisticated online portal
- Transfer process well-documented
- Sends renewal reminders
- More detailed pet profiles allowed
Both let you update your info whenever you move or change phone numbers. This is crucial because an outdated registry is basically useless.

Which One Should You Choose?
Let's get practical about this decision.
Choose PetKey if:
- You want basic protection without ongoing costs
- You're registering multiple pets
- You don't need extra services like vet hotlines
- You want to set it and forget it
- Budget is a primary concern

- You prefer a well-known brand name
For most pet owners, honestly, PetKey's free service is more than enough. The basic recovery function works the same way - someone finds your pet, gets them scanned, and calls you.
But if you're the type of person who wants every possible resource available during an emergency, Home Again's extra features might be worth the annual fee.
Alternative Options to Consider
You're not limited to just these two services. Here are other options worth knowing about:
24PetWatch: Another paid service similar to Home Again with annual fees around $19.99. Includes lost pet recovery and some insurance options.
Found Animals Registry: Free registry service that works with any microchip. Similar to PetKey in offering no-cost registration.
AAHA Universal Pet Microchip Lookup: Not a registry itself, but searches multiple databases at once. Many shelters use this tool.
FreePetChipRegistry.com: Another free option that accepts any ISO-standard microchip.
The good news is most of these registries can look up chips from other companies. You can even register your chip with multiple services for extra protection.
Real User Experiences
I looked through hundreds of reviews to see what actual pet owners say about petkey vs home again.
PetKey users generally say:
- "Love that it's free and actually works"
- "Got my dog back within hours"
- "Simple to use, no complaints"
- "Wish the app was better, but can't complain for free"
Home Again users typically report:
- "The lost pet specialist really helped us search"
- "Worth the annual fee for peace of mind"
- "App is convenient for updating info"
- "Reunited with our cat thanks to their alerts system"
- "Renewal reminders get annoying"
Both services have successfully reunited countless pets with their families. The complaints about Home Again usually involve the cost or forgetting to renew. PetKey complaints are usually about wanting more features.
How Microchip Recovery Actually Works
Understanding the process helps you see why both services work similarly at the core.
- Your pet gets a microchip implanted (usually at the vet)
- You register that chip number with a recovery service
- Your pet gets lost (hopefully never happens)
- Someone finds your pet and takes them to a vet or shelter
- Staff scans your pet for a microchip
- They look up the chip number in the registry database
- They contact you using the information on file
- Happy reunion!
The critical steps - scanning and database lookup - work the same whether you use PetKey or Home Again. The differences come in with alert systems and support services.
Making Your Final Decision
Here's my honest take on the petkey vs home again debate.
If you want a simple, free solution that covers the basics perfectly well, go with PetKey. You'll save money and still have solid protection for your pet.
If you're willing to pay for extra peace of mind and like having additional support services, Home Again is a reputable choice. Just remember to keep your membership active.
The most important thing isn't which service you pick - it's that you actually microchip your pet and register the chip. Too many people get their pet chipped at the vet but never complete the registration. That's like buying a security system but never turning it on.
Final Verdict
Both PetKey and Home Again are legit services that help reunite lost pets with their owners. PetKey wins on price (free is hard to beat), while Home Again offers more comprehensive support services for those willing to pay.
For most pet owners, PetKey provides everything you really need. The free lifetime registration removes any barriers, and the basic recovery system works just fine. You can always register with multiple services for extra protection without spending a dime.
Home Again makes sense for people who want premium features and don't mind the annual cost. Their lost pet specialists and additional services do provide extra value, especially if you travel alot with your pets.
My recommendation? Start with PetKey since it's free. If you later decide you want more features, you can always add a Home Again membership. Your pet can be registered in multiple databases, giving you the best of both worlds.
Whatever you choose, just get your pet microchipped and registered. That's the single most important step you can take to protect your furry family member.
Frequently Asked Questions
Can I register my pet with both PetKey and Home Again?
Yes! You can register the same microchip with multiple recovery services. This actually increases your chances of being contacted if your pet is found, since different vets and shelters might check different databases first.
What happens if I forget to renew my Home Again membership?
Your pet's information stays in the database, but you loose access to the premium features like lost pet specialists and vet hotline. Basic recovery services might still work, but it's better to keep your membership current or switch to a free service.
Do these services work internationally?
Both use ISO-standard chips that can be scanned internationally. However, the recovery services are primarily US-based. If you travel abroad frequently with your pet, check if additional international registration is needed.
How long does microchip registration take?
With both services, online registration typically takes 10-15 minutes. You'll need your pet's microchip number, your contact information, and details about your pet. PetKey is slightly faster since there's no payment processing.
Can I transfer my pet's registration if I sell or rehome them?
Yes, both services allow ownership transfers. The new owner will need the microchip number and may need some information from you to complete the transfer. Always update the registration when a pet changes homes.
Is a microchip a GPS tracker?
No, this is a common misconception. Microchips don't track your pet's location. They only store an identification number that can be scanned when someone finds your pet. For real-time tracking, you need a GPS collar.
Do microchips expire or need to be replaced?
Nope! Microchips are designed to last your pet's entire lifetime. They have no battery and don't wear out. Once it's implanted and registered, you're set. Just remember to update your contact info if you move or change phone numbers.
