Yes and piece of advice to those who carry the number or write the number and carry it with them: Don't. The chances of displacing it are high. Better to store it in a safe or a secure place where you know it will be there at all times. Memorize it. People can't get into your brain, but they can go into your notebook, your electronic notes, etc. if they manage to hack or steal your belongings. Save yourself the headache and prevent your life being stolen from you. And that goes for other important information that is susceptible to fraud.

i mean if you have it in a way thats not obvious, like a code or something then I'm sure its fine

i memorized mine tho
