How to use structured data?

How to use structured data? I have created a new web page recently (https://www.assureshift.in/local-packers-and-movers-wakad). I want to use structured data.
Is this the proper method?

{
 "@context": "https://schema.org",
 "@type": "Organization",
 "url": "http://www.example.com",
 "name": "Unlimited Ball Bearings Corp.",
 "contactPoint": {
   "@type": "ContactPoint",
   "telephone": "+1-401-555-1212",
   "contactType": "Customer service"
 }
}
