Do more than update the database
A microchip is an identification tool, not a GPS tracker. Continue local searching and contact vets, rescues and other appropriate local services.
PetChipHelp is an independent guidance service. We can help identify the database and explain the process, but official microchip records are changed by the database provider that holds the registration.
Have the microchip number?
Check which database appears to hold the record, then go straight to the right provider.
