Thanks for the topic, never thought the CCW had an expiration date. Will put that in my calendar .
In my county it requires renewal by the Sheriff's office every 5 years. Along with that, you have to re-submit all your CCW training/qualification certs along with your renewal application. It's a pain, but a whole lot easier than it was in the 1980s, when you had to prove "a need" to receive a permit. People don't realize that the "shall issue" laws have only been around since the early 1990s.
Back in the day, you had to submit a justification that was almost dissertation length, along with certified notary statements from an employer. Even with all that documentation, the court could restrict your concealed carry to "job performance" only. Meaning that you could carry when working your "need based" job, but were required to be unarmed when you're off the clock at work.
