What is IQ on a resume?
IQ on its own is a meaningless figure, at most a crude indicator for potential. I would never advertise my IQ on a resume or any IQ related communities which I subscribe to. Unless they specifically ask, don't share your IQ. If you're exceptionally smart, they will pick up on it without you needing to mention it.
What do Employers Want?
What employers want is execution and drive - not potential. Employers want accomplishments that took effort and perseverance. You can be Steven Hawkings mental superior but it doesn't matter if you don't do anything with it. If I were an employer and I was choosing between someone average but driven against someone brilliant but unmotivated I'd pick the individual with drive.
If you're employer expressly expects high-IQ individuals then they will weed people out as necessary - they can do it on their own. If they don't expressly expect it you'll be flashing your feathers for nothing, even worse they might see you as a high risk of leaving to greener pastures.
Don't Advertise Arbitrary numbers, Advertise Accomplishments
In all honesty paired with your lacklustre academics employers might read you as saying "I'm exceptionally smart, but I have so little drive I did poorly in school". Even if that's not how you'd frame it - that's how employers will.
Instead of approaching this and saying "I'm smart, hire me", list things you've done that impress people; I've listed things like sophisticated programs I wrote in public school (it's an excellent interview conversation when you are accused of stealing college-level work at age 12), focus programs, extracurricular classes, etc. You don't need (or want) too many, even one or two is enough.
If you don't have any accomplishments that indicate your intelligence then frankly you should lower your expectations and accept you need get points on that resume, and that your academic missteps might cost you a few years while you carve out real achievements.
Are you a good programmer? Work on a complex open-source project and list it on your resume. Amazing artist? Build a portfolio. Gifted at science? Write a paper and get it published. Build real career-specific accomplishments and you'll have a resume with much more meaning than having the bullet point "I'm really smart". If you do really high-profile work you might even be approached.
At the 98th percentile there's still 2 people out of 100 who could be as smart or smarter than you; ~140,000,000 people globally. Every classroom of 50 students statistically has one other student as smart or smarter than you and I. Also, there's plenty of 'average' people who will intensely focus on the same field as you - and can very well beat you if you butt head-to-head unless you put in equal effort. Jobs may often require some sort of on-the-spot test or entry submission - and IQ will count for nothing when someone with laser-focus outperforms you.
Remember that IQ signifies capacity and not usage; just because you have a big library doesn't mean it's full of books. Falling on the high side of the standard deviation isn't an accomplishment on it's own, and shouldn't be treated as one on a resume - all it means is that you can learn and comprehend something faster with less effort, and doesn't automatically give you the 'complete package'.
Reading over your question, it sounds more like you're concerned about how you can cut-corners and skip the line by using your IQ. Saying you deserve extra consideration because you're smart is meaningless because it sounds like you haven't applied any effort to deserve that consideration. If you really want to succeed in the long run, you need to accept that you have to put in real effort to earn your mental stripes and stop trying to coast one one single number you feel makes you exempt.
