What company details your website legally needs - Zephyra Studio

A tax ID, a company registration number, a registered address, these are not decoration at the bottom of a page, they are a legal requirement for any registered business operating through a website. Without them, a visitor has no way to verify who they are dealing with, and an inspector has clear grounds to flag it.

What exactly needs to be there

Serbia's e-commerce law and company law require a business website to clearly display basic identifying details, usually in the footer or on a dedicated "About" or imprint-style page.

• Full company name, exactly as registered
• Tax identification number
• Company registration number
• Registered address (the full address, not just a city)
• Contact e-mail and ideally a phone number
• For online stores, additionally: how and when to file a complaint, and the return policy

Why this matters for trust, not only compliance

These details are not just paperwork for an inspector. A buyer deciding whether to order from an unfamiliar site checks exactly these items before entering a card number, if they cannot find them, the site reads as not a real business, no matter how good the design looks.

This matters especially for sites that charge for services or sell products, missing these details is one of the more common reasons a visitor abandons a cart before paying, not because the price is too high, but because they do not trust the site.

Key takeaways

• A tax ID, registration number, and registered address are a legal requirement for a registered company, not an optional detail.
• Online stores carry an additional obligation to clearly state complaint and return terms.
• Missing these details directly affects whether a buyer trusts the site enough to enter a card number.

Conclusion

If you are not sure whether your site clearly shows every required company detail, or it is buried somewhere nobody finds it, that is something we check and fix as a standard part of building a site.
