A code signing certificate proves your software really came from you and wasn't altered in distribution. So how do you get one? How does the process differ between an individual developer and a company, which documents are required, and what does it cost? Let's walk through it step by step.
The Application Process Through a CA
Code signing certificates are issued by independent Certificate Authorities (CAs). The process comes down to these steps:
- Choose the certificate type — decide whether you want individual, organization, or EV.
- Fill out the application form — applications are made on the CA's website.
- Submit your documents — ID or company documents are requested.
- Go through verification — the CA confirms your details by phone, email, or official records.
- Receive the certificate — after approval, it's delivered by email or on a secure device (token).
This usually takes a few days. EV certificates can take longer because the review is more detailed.
Individual, Organization, and EV Certificates
Code signing certificates come in different types depending on your needs:
| Type | Best for | Advantage | Trade-off |
|---|---|---|---|
| Individual | Solo software developers | Cost-effective for small projects | The certificate shows the developer's name, not a company |
| Organization (OV) | Companies, software firms, corporate developers | The company name appears → more professionalism and trust | More expensive; application takes a bit longer |
| EV | Providers in critical sectors like finance, health, public | Highest assurance; the key is stored on a hardware device | The most costly and time-consuming process |
Which Documents Are Required?
The documents requested depend on the type, and they can vary slightly from one CA to another. In broad strokes:
For an individual certificate
- ✅ ID (passport, driver's license, or national ID card)
- ✅ Proof of address, if your ID doesn't include one
- ✅ A verifiable email address and phone number
For an organization (OV) certificate
- ✅ Trade registry gazette or company registration document
- ✅ Tax number and the company's official paperwork
- ✅ A phone line registered to the company, plus a verification call to that line
- ✅ Domain verification (required by some CAs)
For an EV certificate
- ✅ All of the above, plus additional official verifications
- ✅ A direct verification call with an executive or authorized person
Costs
The cost of a code signing certificate varies by provider and type. Some providers offer extra discounts on multi-year purchases.
Common Mistakes
- ❌ Choosing the wrong certificate — using one that doesn't fit your platform.
- ❌ Forgetting the expiry — an un-renewed certificate leaves your software unsigned.
- ❌ Storing the key insecurely — a stolen private key is the biggest risk.
- ❌ Submitting incomplete documents — this delays or even kills the application.
In Closing: Not Hard, but Important
Don't let getting a code signing certificate intimidate you. Once you pick the right provider, the process runs in an orderly way; the verifications wrap up within a few days, and you end up with a certificate that proves your credibility. For individual developers, it's the fastest way to earn trust; for companies, it's essential for a professional look and customer confidence.
Getting a code signing certificate isn't a burden — it's an investment in your software and your brand.
