Is there a difference between microchip registries?

Yes. Some registries charge annual fees ($15-$25/year), others offer lifetime registration ($19.99-$29.99 one-time). All registries should be searchable via AAHA Universal Pet Microchip Lookup for lost pet recovery.

Do I need to pay a recurring fee for microchip registration?

No. Free registries like Found Animals Foundation offer lifetime registration. Paid registries offer additional services like lost pet alerts and travel certificates.
