Every trademark application must list the “classes” (categories) of goods or services it covers under the Nice Classification system — the same 45 classes used by the USPTO, UK IPO, EUIPO, and most IP offices worldwide. Filing under the wrong class is one of the most common (and costly) trademark mistakes. Type what you sell or offer below to find your likely class, then use our Trademark Cost Calculator to estimate filing fees.
What Are You Selling or Offering?
List each product or service separately. You can search as many as you like — most brands end up needing 1–3 classes.

Trademark Class FAQs
Do I need to register in more than one class?
Only if you actually sell across categories. A clothing brand that also runs an online store typically needs Class 25 (clothing) and Class 35 (retail services) — registering in classes you don’t use can be revoked for non-use and just adds cost. Use the Trademark Cost Calculator to see what each additional class costs in your jurisdiction.
What happens if I file under the wrong class?
Your application may be refused or you may end up unprotected in the category that actually matters for your business. Some offices allow limited amendments early in examination, but you generally cannot add a new class after filing without submitting a new application and paying new fees.
Is this tool a substitute for professional advice?
No. This is a starting point based on common goods/services descriptions, not a legal opinion. Class boundaries can be nuanced (for example, software is split between Class 9 for downloadable products and Class 42 for SaaS), so it’s worth having a trademark professional confirm your exact classes before you file.
Disclaimer: This tool provides general guidance on Nice Classification categories for informational purposes only. It is not legal advice and does not guarantee acceptance by any trademark office. Class definitions and acceptable identifications of goods/services vary slightly by jurisdiction (e.g. USPTO ID Manual vs. EUIPO). Consult a licensed trademark attorney to confirm your classes before filing.
