I tried linking my pet's tag and it says it's invalid?

I am sorry to hear you are having issues with the tag activation process.

If you are getting an Invalid Tag ID Error, please check to be sure it isn't already activated on your pet’s account.


If it isn't activated sometimes numbers are confused for a letter, or vice versa. Here are some of the most commonly confused characters:

  • Zero for the letter "O"
  • One for the letter "I"
  • Two for the letter "Z"
  • Three or Eight for the letter "B"
  • Five for the letter "S"
  • Letter "I/i" for the letter "L"

Also be sure to include any prefixes, dashes, letters, and numbers when activating your tag.
