Getting your pet microchipped is one of the best decisions you will ever make as a pet owner. But here is what most vets don’t tell you clearly enough: the procedure is only the beginning. The chip sitting under your pet’s skin does absolutely nothing on its own until you take the next steps. This guide covers exactly what to do after your pet is microchipped — immediately, within 24 hours, this week, and every year going forward — so the chip can actually do its job.
Quick Answer — What to Do After Your Pet Is Microchipped
Step 1: Get the 15-digit chip number in writing before you leave the vet. Step 2: Register it today at foundanimals.org — free, takes 5 minutes. Step 3: Verify at lookup.aaha.org. Step 4: Monitor the injection site for 48 hours. Step 5: Update your details whenever your phone number or address changes. That’s it — and most pet owners skip steps 2 and 3.

Why What You Do After Microchipping Matters More Than the Chip Itself And What to Do After Your Pet Is Microchipped
A microchip without registration is like a phone that nobody has the number for. The chip is a passive RFID device — it stores nothing more than a 15-digit identification number. It has no GPS, no battery, and no signal of its own. When a shelter scanner passes over your pet, it reads that number. Then a staff member searches the number in a pet registry database. If your number is there — linked to your name and phone — they call you within the hour. If it is not there, your pet becomes an anonymous stray.
This is exactly why what you do after your pet is microchipped is more important than the chip implant itself. The procedure takes 30 seconds and costs $25–$75. The registration takes 5 minutes and is free. Yet over a third of microchipped pets that arrive at shelters have chips that lead nowhere — because their owners thought the job was done when the needle went in.
Want to understand how the chip works before diving into next steps? Read our Complete Guide to Pet Microchipping — covers the technology, procedure, cost, and everything in between.
What to Do Immediately After Your Pet Is Microchipped
These are the things you must do before you even leave the vet clinic — or within the first hour of getting home.
1
Do This Now
Get Your Pet’s 15-Digit Chip Number in Writing
Before you leave the vet
Your vet will have a sticker card or printed document with your pet’s microchip number on it — a 15-digit string of numbers that is unique to your pet for life. This number is everything. Without it, you cannot register, cannot verify, and cannot update your pet’s records.
Before you walk out the door, confirm you have this number in hand. If the vet doesn’t automatically give it to you, ask: “Can I have the microchip number for my records?” They must provide it — it is your pet’s permanent ID.
Store it in three places right now: Save it in your phone contacts as “Pet Chip Number,” photograph the sticker card, and write it in your pet’s health record folder at home.

Do This Now
Ask Your Vet If They Registered the Chip
Before you leave the vet
Some veterinary clinics automatically register your pet’s chip in a database when they perform the procedure. Many do not. You need to know which situation you are in — because if they didn’t register it, you must do it yourself today.
Ask your vet directly: “Did you register this chip in a database? If so, which one, and is it registered to my current contact information?” If the answer is yes — verify it yourself anyway at lookup.aaha.org when you get home. Some vets register chips using their clinic’s contact information rather than yours, which means a shelter would call the vet clinic rather than you.
Never assume: Even if your vet says they registered the chip, still verify at lookup.aaha.org within 24 hours. This takes 2 minutes and costs nothing.
Not sure if your vet registered the chip or want to check a chip that was already implanted? Read our guide: How to Check If Your Dog Is Already Microchipped.
What to Do Within 24 Hours After Your Pet Is Microchipped
These are the most critical steps — the ones that transform the chip from a passive number into a reunion tool. Do these today, not next week.

Register Your Pet’s Chip in a Free Database
Within 24 hours of procedure
This is the single most important step after your pet is microchipped. Go to foundanimals.org/microchip-registry — the most recommended free pet microchip registry in the US — and register your pet’s chip number with your current contact details. It takes 5 minutes and costs nothing.
When you register, fill in every field completely:
- The full 15-digit microchip number — double-check for typos
- Your full legal name
- Your current home address
- Your primary phone number — the one you answer reliably
- A secondary emergency contact — a different person with a different number
- Your email address
- A clear, recent photo of your pet
Why the secondary contact matters: If you are traveling, at work, or in a low-signal area when your pet is found, a secondary contact means someone can be reached immediately. This single addition has reunited thousands of pets with owners who were temporarily unreachable.

Register in a Second Database for Extra Coverage
Same day as registration
The United States has no single national pet microchip registry — different shelters check different databases. Registering in only one database means some shelters may find nothing when they search your pet’s chip number. The fix is simple and free: register in two or three databases.
After registering at Found Animals, also register at
Call your local shelter: Ask them which database they check first when a stray arrives. Then register there too. This one phone call is the most targeted thing you can do to maximize your pet’s chance of a fast reunion.

Do This Today
Verify Your Registration at AAHA Universal Lookup
Within 24–48 hours of registering
After registering, confirm your pet’s chip is actually showing up in the database that shelters use. Go to lookup.aaha.org — the AAHA Universal Pet Microchip Lookup — and enter your pet’s 15-digit chip number. This free tool searches all major US databases simultaneously.
If your chip appears — great, you are protected. If nothing comes up, wait 24–48 hours (some databases take time to sync) and check again. If it still doesn’t appear after 48 hours, contact the registry’s support team — there may be a typo in the chip number or a database sync issue.
This is the step most owners skip — and it is the step that catches problems before they cost you your pet. Take 2 minutes and do it today.
What to Do in the First Week After Your Pet Is Microchipped
6
This Week
Call Your Local Shelter and Confirm Which Database They Use
Within the first week
This step takes one phone call and 2 minutes — but it is one of the most targeted things you can do for your pet’s safety. Call your nearest animal shelter and ask: “Which microchip registry database do you search first when a stray animal arrives?”
The answer might be HomeAgain, PetLink, 24Petwatch, or their own internal system. Whatever they say — make sure your pet is registered there. If you’re not already, register immediately. This single step ensures that when your local shelter scans your pet, they find your number fast. What to Do After Your Pet Is Microchipped

This Week
Update Your Pet’s Collar and ID Tag
Within the first week
A microchip is your pet’s permanent backup identification — but a collar and ID tag are still the first line of defense. When someone finds a lost pet, the first thing they do is look at the collar. A microchip scan requires equipment that most members of the public don’t have.
Make sure your pet’s collar tag shows:
- Your current phone number — ideally two numbers
- Your pet’s name
- Optionally: “I am microchipped” — this signals to finders that a vet or shelter can retrieve owner information quickly
Best combo for maximum safety: Collar with current ID tag + registered microchip + registration in two or more databases. All three layers together give your pet the best possible chance of coming home. What to Do After Your Pet Is Microchipped

This Week
Set an Annual Calendar Reminder
Set it and forget it
One of the most common reasons microchips fail to reunite pets with owners is outdated contact information. People move. Phone numbers change. Emergency contacts change. The chip registration stays the same unless you update it — and most people forget.
Right now, set a recurring annual calendar reminder on your phone — pick your pet’s birthday, adoption anniversary, or any date you’ll remember. When the reminder fires each year, spend 2 minutes logging into your registry and verifying your address, phone number, and emergency contact are still current.
Name the reminder clearly: “Update pet microchip registration” — so you know exactly what to do when it appears.
Post-Microchipping Aftercare — What Is Normal and What Is Not
Microchipping is a very safe, minor procedure — but knowing what to expect in the hours and days after helps you monitor your pet confidently and catch any problems early.
| What You Might See | Timeframe | Normal or See Vet? | What to Do |
|---|---|---|---|
| Mild tenderness at injection site | First 24 hrs | ✓ Normal | Avoid pressing the area. Give treats and cuddles. Monitor only. |
| Small firm lump under skin | First 1–2 weeks | ✓ Usually normal | Likely the chip itself or minor scar tissue forming. Mention at next vet visit if it persists. |
| Pet scratching at the area | First 24–48 hrs | ✓ Usually normal | Minor irritation. Monitor. Use a soft cone if scratching is excessive to prevent infection. |
| Minor swelling — not spreading | First 24 hrs | ✓ Normal | Apply a cool cloth gently for a few minutes if pet seems bothered. Monitor progress. |
| Swelling increasing after 48 hrs | After 48 hrs | ⚠ Call your vet | Increasing swelling after 48 hours is unusual. Contact your vet for evaluation. |
| Redness spreading from the site | Any time | ⚠ Call your vet | Could indicate infection. Contact your vet promptly. |
| Discharge or oozing | Any time | ⚠ Call your vet | Not normal. Potential infection. See your vet same day. |
| Lethargy lasting more than a day | After 24 hrs | ⚠ Call your vet | Unusual after a routine microchip procedure. Seek veterinary advice. |
Most Pets Are Back to Normal Within Minutes
The vast majority of dogs and cats show no signs of discomfort after microchipping and return to their normal behavior within minutes of the procedure. Serious side effects are genuinely rare. When in doubt about anything you observe, call your vet — that is always the right move.

Annual Maintenance — What to Do Every Year After Microchipping
The chip itself is a set-and-forget device — it lasts 25+ years with zero maintenance. But the registration requires your active attention, because your life changes even when the chip doesn’t.
1
Every Year
Verify your contact details in every registry you use
Log into each registry where your pet is registered and confirm your phone number, address, and emergency contact are all still accurate. Takes 5 minutes per registry. This is the single most important annual task for any microchipped pet owner.
2
Every Year
Ask your vet to scan the chip during your annual wellness visit
Ask your vet to run a scanner over your pet at every annual checkup. This confirms the chip is still in place, still readable, and has not migrated to an unusual location. It takes 15 seconds and costs nothing extra in most clinics.
3
Every Year
Re-verify at lookup.aaha.org
After confirming your registry details are current, re-search your pet’s chip number at lookup.aaha.org to confirm everything is still showing correctly. Databases occasionally experience syncing issues — this 2-minute check catches any problems before they matter.
4
When Life Changes
Update immediately when you move or change your number
Don’t wait for the annual reminder. Any time your phone number, home address, or emergency contact changes — log into your registry the same week and update your records. A chip registered to an old phone number is nearly useless in a reunion scenario.
5
When Ownership Changes
Transfer chip registration if you rehome your pet
If you ever need to rehome your pet, transfer the chip registration to the new owner’s name and contact details. Contact the registry you used and follow their ownership transfer process. Never leave the chip registered to a previous owner — this creates confusion if the pet is ever lost.
8 Critical Mistakes Pet Owners Make After Microchipping
These are the errors that turn a life-saving chip into a useless piece of glass — all avoidable, all common.
Assuming the chip is enough — not registering at all
Fix: Register at foundanimals.org today — free, 5 minutes
The most common and most dangerous mistake. Over a third of microchipped pets at shelters have chips that lead nowhere because the owner thought the procedure itself was sufficient.
Registering but never verifying at AAHA lookup
Fix: Search your chip number at lookup.aaha.org
Many owners register correctly but never confirm the chip actually appears in the universal search system. A data sync error or number typo can make registration invisible to shelters.
Only registering in one database
Fix: Register in two or three free registries
Different shelters use different databases. Being in only one registry means some shelters may find nothing when they search your chip, even though you are technically registered.
Not updating contact details after moving
Fix: Update registry same week you change address or phone
A chip registered to your old address sends a shelter to the wrong location. A chip registered to a disconnected number goes unanswered. Outdated info is nearly as bad as no registration.
Losing the chip number and never recovering it
Fix: Save it in three places — phone, photo, pet records
Without the chip number, you cannot verify, update, or re-register. If lost, your vet can scan your pet to recover it — but save it in multiple places to avoid the hassle.
Not adding a secondary emergency contact
Fix: Add a backup contact in your registry profile now
If you’re unreachable when your pet is found, a secondary contact gives shelters an immediate backup. This one addition has been the difference between reunion and failed contact in countless cases.
Removing the collar because “the chip is enough”
Fix: Keep collar and ID tag on at all times
A chip requires a scanner to read. A collar is visible to anyone who finds your pet. Both serve different purposes — a collar is the first line, the chip is the permanent backup. Use both.
Never scanning the chip again after implantation
Fix: Ask vet to scan the chip at every annual wellness visit
Chips very rarely fail, but it does happen. A chip that has stopped reading offers no protection. Annual scanning at your vet visit confirms the chip is still working correctly — and it’s free.
