Microchips tend to be a confusing part of pet travel, so we like to revisit this issue every once in a while in order to help clarify some of the muddier details.
In particular, after publishing a post about whether AVID microchips are compatible for international pet travel, we've been receiving a lot of questions about HomeAgain microchips and whether or not they're ISO compatible. In short, yes they are, but keep reading to find out more.
Take a look at our previous blog post on this topic for more info on AVID and HomeAgain microchips, and read on to explore some frequently asked questions about microchips and pet relocation.
Microchips are tiny computer chips that have been programmed with identification numbers. They are used to facilitate safe and orderly animal importation into different countries, and they're no bigger than a grain of rice. Microchips are implanted with a hypodermic needle, usually between a pet's shoulder blades, and the process requires no anesthesia or sedation.How do you know which microchip you need?
Different countries have different requirements when it comes to microchipping, so before a trip it's important to double check the specific rules and regulations of your destination. International travelers will most likely need to secure an ISO (International Organization for Standardization) approved chip.What do you do if you already have one kind of microchip and find out you need another?
The original chip does not have to be removed. Just make sure your vet letter states that there are two chips so that the official in charge of scanning will know to look for the other chip if the wrong information initially shows up.Which microchips will allow entry into the EU?
The HomeAgain chip is ISO compatible, as is the AVID Euro chip (which is different from the AVID Standard). Some countries, such as Hong Kong, still require the AVID Standard microchip, so again, double check each nation's requirements before you travel internationally.
