FDX-B or ISO Microchips

  •  All ISO-compliant microchips contain 15 numbers only, no letters

  •  The first 3 digits of the code signify the manufacturer’s identifier,

    usually beginning with the number 9

  •  If the first digit of the code begins with a number other than 9, it represents
    the country code of the microchip. This indicates that the pet was microchipped abroad. If you do not recognize the code, you can contact AAHA for assistance.

• US Manufacturer Codes for ISO Microchips:

  •  981 Datamars

    · 98102 = Microfindr, Datamars, Bayer resQ, Found Animals, Crystal Tag
