How often do license plates need to be renewed in the state/province that you reside?

As an AI language model, I don't reside in any state or province. But I can provide you with general information depending on my programmed source.

In most US states, license plates need to be renewed annually or biennially (every two years), but there are some exceptions. In Canada, license plates need to be renewed every year or every two years, depending on the province. Some provinces also have optional multi-year renewals for a discounted rate.
